Hubei
–
Hubei is a province of the Peoples Republic of China, located in the Central China region. The name of the province north of the lake, referring to its position north of Dongting Lake. The provincial capital is Wuhan, a major thoroughfare and the political, cultural. It borders Henan to the north, Anhui to the east, Jiangxi to the southeast, Hunan to the south, Chongqing to the west, the high-profile Three Gorges Dam is located at Yichang, in the west of the province. The Hubei region was home to sophisticated Neolithic cultures, by the Spring and Autumn period, the territory of todays Hubei was part of the powerful State of Chu. During the Warring States period Chu became the major adversary of the upstart State of Qin to the northwest, which began to assert itself by outward expansionism. As wars between Qin and Chu ensued, Chu lost more and more land, first its dominance over the Sichuan Basin, then its heartland, which correspond to modern Hubei. In 223 BC Qin chased down the remnants of the Chu regime, Qin founded the Qin dynasty in 221 BC, the first unified state in the region. Qin was succeeded by the Han dynasty in 206 BC, which established the province of Jingzhou in what is now Hubei, the Qin and Han played an active role in the agricultural colonization of Hubei, maintaining a system of river dikes to protect farmland from summer floods. Towards the end of the Han Dynasty in the beginning of the 3rd century, the incursion of northern nomadic peoples into the region at the beginning of the 4th century began nearly three centuries of division into a nomad-ruled north and a Han Chinese-ruled south. Hubei, to the South, remained under southern rule for this entire period, until the unification of China by the Sui dynasty in 589. After the Tang dynasty disintegrated in the 10th century, Hubei came under the control of several regional regimes, Jingnan in the center, Wu to the east, and the Five Dynasties to the north. The Song dynasty reunified the region in 982 and placed most of Hubei into Jinghubei Circuit, Mongols conquered the region in 1279, and under their rule the province of Huguang was established, covering Hubei, Hunan, and parts of Guangdong and Guangxi. The Ming dynasty drove out the Mongols in 1368 and their version of Huguang province was smaller, and corresponded almost entirely to the modern provinces of Hubei and Hunan combined. While Hubei was geographically removed from the centers of the Ming power, during the last years of the Ming, todays Hubei was ravaged several times by the rebel armies of Zhang Xianzhong and Li Zicheng. The Manchu Qing dynasty which had much of the region in 1644, soon split Huguang into the provinces of Hubei. The Huangshi/Daye area, south-east of Wuhan, became an important center of mining, in 1911 the Wuchang Uprising took place in modern-day Wuhan, overthrowing the Qing dynasty and establishing the Republic of China. In 1927 Wuhan became the seat of a government established by left-wing elements of the Kuomintang, led by Wang Jingwei, during World War II the eastern parts of Hubei were conquered and occupied by Japan while the western parts remained under Chinese control

Hunan
–
Hunan Province is the 7th most populous Province of China and the 10th most extensive by area. The name Hunan means south of Lake Dongting, a lake in the northeast of the province, vehicle license plates from Hunan are marked Xiang, after the Xiang River, which runs from south to north through Hunan and forms part of the largest drainage system for the province. Hunans primeval forests were first occupied by the ancestors of the modern Miao, Tujia, Dong and it entered the written history of China around 350 BC, when under the kings of the Zhou Dynasty, it became part of the State of Chu. After Qin conquered the Chu heartland in 278 BC, the region came under the control of Qin, the agricultural colonization of the lowlands was carried out in part by the Han state, which managed river dikes to protect farmland from floods. To this day many of the villages in Hunan are named after the Han families who settled there. Migration from the north was especially prevalent during the Eastern Jin Dynasty and the Southern and Northern Dynasties Periods, during the Five Dynasties and Ten Kingdoms Period, Hunan was home to its own independent regime, Ma Chu. Hunan and Hubei became a part of the province of Huguang until the Qing dynasty, Hunan province was created in 1664 from Huguang, renamed to its current name in 1723. Hunan became an important communications center due to its position on the Yangzi River and it was an important centre of scholarly activity and Confucian thought, particularly in the Yuelu Academy in Changsha. It was also on the Imperial Highway constructed between northern and southern China, the land produced grain so abundantly that it fed many parts of China with its surpluses. The population continued to climb until, by the century, Hunan became overcrowded. Some of the uprisings, such as the ten-year Miao Rebellion of 1795–1806, were caused by ethnic tensions, the Taiping Rebellion began in the south in Guangxi Province in 1850. The rebellion spread into Hunan and then further eastward along the Yangzi River valley, ultimately, it was a Hunanese army under Zeng Guofan who marched into Nanjing to put down the uprising in 1864. Hunan was relatively quiet until 1910 when there were uprisings against the crumbling Qing dynasty and it was led by Hunanese native Mao Zedong, and established a short-lived Hunan Soviet in 1927. The Communists maintained an army in the mountains along the Hunan-Jiangxi border until 1934. Under pressure from the Nationalist Kuomintang forces, they began the Long March to bases in Shaanxi Province, after the departure of the Communists, the KMT army fought against the Japanese in the second Sino-Japanese war. They defended the Changsha until it fell in 1944, japan launched Operation Ichigo, a plan to control the railroad from Wuchang to Guangzhou. Hunan was relatively unscathed by the war that followed the defeat of the Japanese in 1945. In 1949, the Communists returned once more as the Nationalists retreated southward, as Mao Zedongs home province, Hunan supported the Cultural Revolution of 1966–1976

Yangtze
–
The Yangtze River, known in China as the Cháng Jiāng or the Yángzǐ Jiāng, is the longest river in Asia and the third-longest in the world. The river is the longest in the world to flow entirely within one country and it drains one-fifth of the land area of the Peoples Republic of China and its river basin is home to one-third of the countrys population. The Yangtze is the sixth-largest river by volume in the world. The Yangtze River plays a role in the history, culture. The prosperous Yangtze River Delta generates as much as 20% of the PRCs GDP, for thousands of years, the river has been used for water, irrigation, sanitation, transportation, industry, boundary-marking and war. The Three Gorges Dam on the Yangtze River is the largest hydro-electric power station in the world, in recent years, the river has suffered from industrial pollution, agricultural run-off, siltation, and loss of wetland and lakes, which exacerbates seasonal flooding. Some sections of the river are now protected as nature reserves, a stretch of the upstream Yangtze flowing through deep gorges in western Yunnan is part of the Three Parallel Rivers of Yunnan Protected Areas, a UNESCO World Heritage Site. In mid-2014 the Chinese government announced it was building a transport network, comprising railways, roads and airports. Because the source of the Yangtze was not ascertained until modern times, Yangtze was actually the name of Chang Jiang for the lower part from Nanjing to the river mouth at Shanghai. In modern Chinese, Yangtze is still used to refer to the part of Chang Jiang from Nanjing to the river mouth. Yangtze never stands for the whole Chang Jiang, Chang Jiang is the modern Chinese name for the lower 2,884 km of the Yangtze from its confluence with the Min River at Yibin in Sichuan Province to the river mouth at Shanghai. Chang Jiang literally means the Long River, in Old Chinese, this stretch of the Yangtze was simply called Jiang/Kiang 江, a character of phono-semantic compound origin, combining the water radical 氵 with the homophone 工. Krong was probably a word in the Austroasiatic language of local peoples such as the Yue, similar to *krong in Proto-Vietnamese and krung in Mon, all meaning river, it is related to modern Vietnamese sông and Khmer kôngkea. By the Han Dynasty, Jiang had come to any river in Chinese. The epithet 長, means long, was first formally applied to the river during the Six Dynasties period, various sections of Chang Jiang have local names. From Yibin to Yichang, the river through Sichuan and Chongqing Municipality is also known as the Chuan Jiang or Sichuan River, in the Hubei Province, the river is also called the Jing Jiang or the Jing River after Jingzhou. In Anhui Province, the takes on the local name Wan Jiang after the shorthand name for Anhui. And Yangzi Jiang t 揚子江s 扬子江, p Yángzǐjiāng) or the Yangzi River, the name likely comes from an ancient ferry crossing called Yangzi or Yangzijin

Badong County
–
Badong County is a county located in the extreme west of Hubei province, Peoples Republic of China. It is under the administration of Enshi Prefecture, the Yangtze River flows through the county and the county seat is located just east of the Wu Gorge in the Three Gorges region. Badong County is famous for the Shen Nong Stream gorges located near Badong town, the stream itself falls into the Yangtze opposite the Badong center city. The Badong county seat, commonly referred to simply as Badong, is in the town of Xinling, dito nakasira si badong Other name Coal mining in small pits is the main commercial activity in the region, along with farming. There is also a cement factory on the river to the east of the town. The rural population of Badong County, as many other parts of inland China, has seen major changes in the past two decades. The new freedom to travel and work in parts of China has also led to a major exodus of workers to the coastal areas of China to find work. The older people tend to stay in the villages, and the workers return to have their children. The overall result is that many villages in Badong are shrinking, Badong County is divided into 10 towns and 2 townships. They two sides of the Yangtze are connected by the Badong Bridge, due to the difficult terrain and the road conditions, the most convenient way to reach Badongs county seat is with a Yangtze riverboat. Both regular boats and hydrofoils call in the busy Badong harbor on the way up, the county has one Yangtze crossing, the Badong Bridge, carrying China National Highway 209. The highway crosses the northern half of the county from the northeast to the southwest, as of 2009, Highway 209 was little more than a dirt road for a 20-km stretch north of the bridge. China National Highway 318 crosses the southern part of the county from the east to the west, the new G50 Shanghai–Chongqing Expressway and Yichang-Wanzhou Railway have been recently completed along the same corridor as well. The Siduhe Bridge on the new highway, located near Yesanguan town, is one of the longest bridges of its kinds, the Badong Station on the new railway, located near Yesanguan Town in the south-central part of the county, is the only railway station within the county. At the planning station it was known as Yesanguan Station, due to its location, a number of provincial highways run north to south through the county. Deng Yujiao incident, occurred in Badong in 2009 Ran Jianxin incident, occurred in Lichuan and Badong in May, gnodab, the opposite of Badong Official website of Badong County Government

Sichuan Basin
–
The Sichuan Basin, or Szechwan Basin, is a lowland region in southwestern China. It comprises the central and eastern portions of Sichuan province, due to its relative flatness and fertile grounds, it is heavily populated with a population of more than 100 million. In addition to being a dominant geographical feature of the region, the Sichuan basin also constitutes a cultural sphere that is distinguished by its own customs, cuisine. It is also called the Red Basin and it is famous for rice cultivation. It is also the principal gas-producing region of China, Mountains frame the Sichuan Basin on all sides, the Qionglai Range in the west the Longmen Mountains in the northwest the Daba in the northeast. The Yangtze River, flowing from the Sichuan Basin into the eastern China, the Sichuan Basin consists of low hills and alluvial plains, and several major rivers flow into the Chang Jiang, which passes through the southern part of the basin. The seismically active Longmenshan Fault - the source of the catastrophic 2008 Sichuan earthquake - runs along the boundary of the basin. See the articles on Chongqing and Chengdu for further details, a greater variety of natural landscapes and wildlife has been at least partially preserved in the mountains surrounding the basin. The natural ecosystems of mountains have been classified by the World Wildlife Fund as the Qionglai-Minshan conifer forests. It was in the hilly Lichuan County, on the eastern fringe of the basin. The Dawn Redwood is distinctive because it is a deciduous conifer

Karst
–
Karst topography is a landscape formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves and it has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes, the English word karst was borrowed from German Karst in the late 19th century. The German word came into use before the 19th century, according to the prevalent interpretation, the term is derived from the German name for the Karst region, a limestone plateau above the city of Trieste in the northern Adriatic. Scholars disagree, however, on whether the German word was borrowed from Slovene, the Slovene common noun kras was first attested in the 18th century, and the adjective form kraški in the 16th century. The Slovene words arose through metathesis from the reconstructed form *korsъ, ultimately, the word is of Mediterranean origin, believed to derive from some Romanized Illyrian base. It has been suggested that the word may derive from the Proto-Indo-European root karra- rock, the name may also be connected to the oronym Karsádios oros cited by Ptolemy, and perhaps also to Latin Carusardius. The development of karst occurs whenever acidic water starts to break down the surface of bedrock near its cracks, as the bedrock continues to degrade, its cracks tend to get bigger. As time goes on, these fractures will become wider, if this underground drainage system does form, it will speed up the development of karst formations there because more water will be able to flow through the region, giving it more erosive power. The carbonic acid that causes karstic features is formed as rain passes through the atmosphere picking up carbon dioxide, once the rain reaches the ground, it may pass through soil that can provide much more CO2 to form a weak carbonic acid solution, which dissolves calcium carbonate. The oxidation of sulfides leading to the formation of acid can also be one of the corrosion factors in karst formation. As oxygen -rich surface waters seep into deep anoxic karst systems, they bring oxygen, sulfuric acid then reacts with calcium carbonate, causing increased erosion within the limestone formation. This chain of reactions is, This reaction chain forms gypsum, the karstification of a landscape may result in a variety of large- or small-scale features both on the surface and beneath. On exposed surfaces, small features may include solution flutes, runnels, limestone pavement, medium-sized surface features may include sinkholes or cenotes, vertical shafts, foibe, disappearing streams, and reappearing springs. Large-scale features may include limestone pavements, poljes, and karst valleys, mature karst landscapes, where more bedrock has been removed than remains, may result in karst towers, or haystack/eggbox landscapes. Beneath the surface, complex underground systems and extensive caves. Some of the most dramatic of these formations can be seen in Thailands Phangnga Bay, calcium carbonate dissolved into water may precipitate out where the water discharges some of its dissolved carbon dioxide. Rivers which emerge from springs may produce tufa terraces, consisting of layers of calcite deposited over extended periods of time, in caves, a variety of features collectively called speleothems are formed by deposition of calcium carbonate and other dissolved minerals

Monsoon
–
Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is sometimes used for locally heavy but short-term rains. The major monsoon systems of the world consist of the West African and Asia-Australian monsoons, the inclusion of the North and South American monsoons with incomplete wind reversal has been debated. The south-west monsoon winds are called Nairutya Maarut in India, the English monsoon came from Portuguese monção, ultimately from Arabic mawsim and/or Hindi mausam, perhaps partly via early modern Dutch monsun. Strengthening of the Asian monsoon has been linked to the uplift of the Tibetan Plateau after the collision of the Indian sub-continent and Asia around 50 million years ago. Because of studies of records from the Arabian Sea and that of the wind-blown dust in the Loess Plateau of China, testing of this hypothesis awaits deep ocean sampling by the Integrated Ocean Drilling Program. The monsoon has varied significantly in strength since this time, largely linked to climate change. A study of marine plankton suggested that the Indian Monsoon strengthened around 5 million years ago, then, during ice periods, the sea level fell and the Indonesian Seaway closed. When this happened, cold waters in the Pacific were impeded from flowing into the Indian Ocean and it is believed that the resulting increase in sea surface temperatures in the Indian Ocean increased the intensity of monsoons. Five episodes during the Quaternary at 2.22 Ma,1.83 Ma,0.68 Ma,0.45 Ma and 0.04 Ma were identified which showed a weakening of Leeuwin Current. The weakening of the LC would have an effect on the sea surface temperature field in the Indian Ocean, thus these five intervals could probably be those of considerable lowering of SST in the Indian Ocean and would have influenced Indian monsoon intensity. The impact of monsoon on the weather is different from place to place. In some places there is just a likelihood of having a more or less rain. In other places, quasi semi-deserts are turned into green grasslands where all sorts of plants. The Indian Monsoon turns large parts of India from a kind of semi-desert into green lands, see photos only taken 3 months apart in the Western Ghats. In places like this it is crucial for farmers to have the right timing for putting the seeds on the fields, Monsoons are large-scale sea breezes which occur when the temperature on land is significantly warmer or cooler than the temperature of the ocean. These temperature imbalances happen because oceans and land absorb heat in different ways, in contrast, dirt, sand, and rocks have lower heat capacities, and they can only transmit heat into the earth by conduction and not by convection. Therefore, bodies of water stay at an even temperature

Miao people
–
The Miao is an ethnic group recognized by the government of China as one of the 55 official minority groups. Miao is a Chinese term and does not reflect the self-designations of the component groups of people, which include Hmong, Hmub, Xong, and A-Hmao. Because of the given reasons, many Miao peoples cannot communicate with each other in their mother tongues. The Miao live primarily in southern Chinas mountains, in the provinces of Guizhou, Hunan, Yunnan, Sichuan, Guangxi, Hainan, Guangdong, some members of the Miao sub-groups, most notably the Hmong people, have migrated out of China into Southeast Asia. Following the communist takeover of Laos in 1975, a group of Hmong refugees resettled in several Western nations, mainly in the United States, France. There has been a recent tendency by Hmong Americans to group all Miao peoples together under the term Hmong because of their disdain for the Chinese term Miao, the term Miao gained official status in 1949 as a minzu encompassing a group of linguistically-related ethnic minorities in Southwest China. Historically, the term Miao had been applied inconsistently to a variety of non-Han peoples, early Western writers used Chinese-based names in various transcriptions, Miao, Miao-tse, Miao-tsze, Meau, Meo, mo, miao-tseu etc. In Southeast Asian contexts words derived from the Chinese Miao took on a sense which was perceived as derogatory by the Hmong subgroup living in that region, in China, however, the term has no such context and is used by the Miao people themselves, of every group. The later prominence of Hmong people in the West has led to a situation where the entire Miao linguistic/cultural family is referred to as Hmong in English language sources. Following the recent increased interaction of Hmong in the West with Miao in China it is reported that some upwardly aspiring non-Hmong Miao have even begun to identify themselves as Hmong. However, most non-Hmong Miao in China are unfamiliar with the term as referring to their group and continue to use Miao. Though the Miao themselves use various self-designations, the Chinese traditionally classify them according to the most characteristic colour of the womens clothes.6 million. Outside of China, members of the Miao linguistic/cultural family sub-group or nations of the Hmong live in Thailand, Laos, Vietnam and Burma due to outward migrations starting in the 18th century. As a result of recent migrations in the aftermath of the Indochina and Vietnam Wars from 1949–75, many Hmong people now live in the United States, French Guiana, France, altogether, there are approximately 8 million speakers in the Miao language family. This language family, which consists of 6 languages and around 35 dialects belongs to the Hmong/Miao branch of the Hmong–Mien language family, there are about 1. 5–2 million Hmong in China. Note, The Miao areas of Sichuan province became part of the newly created Chongqing Municipality in 1997, most Miao currently live in China. Miao population growth in China,1953,2,510,0001964,2,780,0001982,5,030,0001990,7,390,0003,600,000 Miao, about half of the entire Chinese Miao population, were in Guizhou in 1990. There are 2,000,000 Hmong spread throughout northern Vietnam, Laos, Burma,174,000 live in Thailand, where they are one of the six main hill tribes

Pinyin
–
Pinyin, or Hànyǔ Pīnyīn, is the official romanization system for Standard Chinese in mainland China, Malaysia, Singapore, and Taiwan. It is often used to teach Standard Chinese, which is written using Chinese characters. The system includes four diacritics denoting tones, Pinyin without tone marks is used to spell Chinese names and words in languages written with the Latin alphabet, and also in certain computer input methods to enter Chinese characters. The pinyin system was developed in the 1950s by many linguists, including Zhou Youguang and it was published by the Chinese government in 1958 and revised several times. The International Organization for Standardization adopted pinyin as a standard in 1982. The system was adopted as the standard in Taiwan in 2009. The word Hànyǔ means the language of the Han people. In 1605, the Jesuit missionary Matteo Ricci published Xizi Qiji in Beijing and this was the first book to use the Roman alphabet to write the Chinese language. Twenty years later, another Jesuit in China, Nicolas Trigault, neither book had much immediate impact on the way in which Chinese thought about their writing system, and the romanizations they described were intended more for Westerners than for the Chinese. One of the earliest Chinese thinkers to relate Western alphabets to Chinese was late Ming to early Qing Dynasty scholar-official, the first late Qing reformer to propose that China adopt a system of spelling was Song Shu. A student of the great scholars Yu Yue and Zhang Taiyan, Song had been to Japan and observed the effect of the kana syllabaries. This galvanized him into activity on a number of fronts, one of the most important being reform of the script, while Song did not himself actually create a system for spelling Sinitic languages, his discussion proved fertile and led to a proliferation of schemes for phonetic scripts. The Wade–Giles system was produced by Thomas Wade in 1859, and it was popular and used in English-language publications outside China until 1979. This Sin Wenz or New Writing was much more sophisticated than earlier alphabets. In 1940, several members attended a Border Region Sin Wenz Society convention. Mao Zedong and Zhu De, head of the army, both contributed their calligraphy for the masthead of the Sin Wenz Societys new journal. Outside the CCP, other prominent supporters included Sun Yat-sens son, Sun Fo, Cai Yuanpei, the countrys most prestigious educator, Tao Xingzhi, an educational reformer. Over thirty journals soon appeared written in Sin Wenz, plus large numbers of translations, biographies, some contemporary Chinese literature, and a spectrum of textbooks

Chongqing
–
Chongqing, formerly transliterated as Chungking, is a major city in Southwest China and one of the Five national central cities in China. Administratively, it is one of Chinas four direct-controlled municipalities, the municipality was created on 14 March 1997, succeeding the sub-provincial city administration that was part of Sichuan Province. Chongqings population as of 2015 is just over 30 million with a population of 18.38 million. The official abbreviation of the city, Yu, was approved by the State Council on 18 April 1997 and this abbreviation is derived from the old name of a part of the Jialing River that runs through Chongqing and feeds into the Yangtze River. Chongqing was also a Sichuan province municipality during the Republic of China administration, Chongqing has a significant history and culture and serves as the economic centre of the upstream Yangtze basin. It is a manufacturing centre and transportation hub, a July 2012 report by the Economist Intelligence Unit described it as one of Chinas 13 emerging megacities. Tradition associates Chongqing with the State of Ba, the Ba people supposedly established Chongqing during the Spring and Autumn period after moving from their first capital Yicheng in Hubei under pressure from Chu. This new capital was first named Jiangzhou, in 316 BC, however, the state of Ba was conquered by the State of Qin. Jiangzhou subsequently remained under Qin Shi Huangs rule during the Qin Dynasty, the successor of the Qin State, and under the control of Han Dynasty emperors. Jiangzhou was subsequently renamed during the Southern and Northern Dynasties to Chu Prefecture, then in 581 AD to Yu Prefecture, the name Yu however survives to this day as an abbreviation for Chongqing, and the city centre where the old town stood is also called Yuzhong. It received its current name in 1189, after Prince Zhao Dun of the Southern Song Dynasty described his crowning as king, in his honour, Yu Prefecture was therefore renamed Chongqing subprefecture marking the occasion of his enthronement. In 1362, Ming Yuzhen, a peasant rebelling leader, established the Daxia Kingdom at Chongqing for a short time, in 1621, another short-lived kingdom of Daliang was established by She Chongming with Chongqing as its capital. The Manchus later conquered the province, and during the Qing Dynasty, immigration to Chongqing, in 1890, the British Consulate General was opened in Chongqing. The following year, the city became the first inland commerce port open to foreigners, the French, German, US and Japanese consulates were opened in Chongqing in 1896–1904. During the Second Sino-Japanese War, it was Generalissimo Chiang Kai-sheks provisional capital, the city was also visited by Lord Louis Mountbatten, the Supreme Commander of SEAC which was itself headquartered in Ceylon, modern day Sri Lanka. Chiang Kai Shek as Supreme Commander in China worked closely with Stilwell, the Japanese Air Force heavily bombed it. Due to its mountainous environment, many people were saved from the bombing, due to the bravery, contributions and sacrifices made by the local people during World War II, Chongqing became known as the City of Heroes. Many factories and universities were relocated from eastern China to Chongqing during the war, in late November 1949 the Nationalist KMT government fled the city

Precipitation
–
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, graupel, Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and precipitates. Thus, fog and mist are not precipitation but suspensions, because the vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated, Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers, moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain. This process is active when freezing rain is occurring. A stationary front is often present near the area of freezing rain, provided necessary and sufficient atmospheric moisture content, the moisture within the rising air will condense into clouds, namely stratus and cumulonimbus. Eventually, the droplets will grow large enough to form raindrops. Lake-effect snowfall can be locally heavy, thundersnow is possible within a cyclones comma head and within lake effect precipitation bands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation, on the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. The movement of the trough, or intertropical convergence zone. Precipitation is a component of the water cycle, and is responsible for depositing the fresh water on the planet. Approximately 505,000 cubic kilometres of water falls as precipitation each year,398,000 cubic kilometres of it over the oceans and 107,000 cubic kilometres over land. Given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres, Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Precipitation may occur on celestial bodies, e. g. when it gets cold, Mars has precipitation which most likely takes the form of frost. Precipitation is a component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 505,000 km3 of water falls as precipitation each year,398,000 km3 of it over the oceans, given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres. Mechanisms of producing precipitation include convective, stratiform, and orographic rainfall, Precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice

Tujia people
–
The Tujia, with a total population of over 8 million, is the 8th largest ethnic minority in the Peoples Republic of China. They live in the Wuling Mountains, straddling the borders of Hunan, Hubei and Guizhou Provinces. The endonym Bizika means native dwellers, in Chinese, Tujia means also local, as distinguished from the Hakka whose name implies wandering. The Ba Kingdom reached the zenith of its power between 600 BC and 400 BC but was destroyed by the Qin in 316 BC. After being referred to by a succession of different names in ancient documents. The Tujia tusi chieftains reached the zenith of their power under the Ming Dynasty and they achieved this through their reputation as providers of fierce, highly disciplined fighting men, who were employed by the emperor to suppress revolts by other minorities. On numerous occasions, they helped defend China against outside invaders. The Manchus invaded and conquered the Ming in 1644 and established the Great Qing Empire, ever suspicious of local rulers, the Qing emperors always tried to replace Han officials with Manchu officials wherever they could. In the early 18th century, the Qing court finally felt secure enough to direct control over minority areas as well. This process, known as gaituguiliu, was carried out throughout south-west China gradually and, in general, the court adopted a carrot-and-stick approach of lavish pensions for compliant chieftains, coupled with a huge show of military force on the borders of their territories. Most of the Tujia areas returned to control during the period 1728-1735. With the weakening of central Qing rule, numerous large-scale uprisings occurred culminating in the Taiping Rebellion which affected the area badly, following the collapse of the Qing Dynasty, the Tujia found themselves caught between various competing warlords. More and more land was given over to the cultivation of high-earning opium at the insistence of wealthy landlords, after the founding of the Peoples Republic of China in 1949, Tujia areas came under Communist control, and banditry was rapidly eradicated. The Great Leap Forward led to famine in Tujia communities. The Tujia were officially recognised as one of the 55 ethnic minorities in January 1957, State Councillor Dai Bingguo, one of Chinas top officials on foreign policy, is the most prominent Tujia in the Chinese government. Today, traditional Tujia customs can only be found in the most remote areas and they are also famous for their richly-patterned brocade, known as xilankapu, a product that in earlier days regularly figured in their tribute payments to the Chinese court. Regarding religion, most of the Tujia worship a white tiger totem, Tujia is a Tibeto-Burman language and is usually considered an isolate within this group, although it has grammatical and phonological similarities with Yi. Today there are at most 70,000 native speakers of the Tujia language, most of live in the northern parts Xiangxi Tujia
