Cyclogenesis

Cyclogenesis is the development or strengthening of cyclonic circulation in the atmosphere. Cyclogenesis is an umbrella term for at least three different processes, all of which result in the developm
This collage of GOES 13 satellite images shows the development of a nor'easter over two days.
This image displays a dense cloud pattern and arcing band of convection, indicating a young, developing cyclone.
The diffuse cloud pattern in this image indicates an old, low-pressure system undergoing Cyclolysis.
This image illustrates the relative positions of two storm systems over the north-eastern Pacific.
Low-pressure area
Videos
In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area. Low-pressure ar
A low-pressure system over Iceland.
This depiction of the Hadley cell shows the process which sustains low-pressure areas. Diverging winds aloft allow for lower pressure and convergence at the Earth's surface, which leads to upward motion.
