Atmospheric convection is the vertical transport of heat and moisture in the atmosphere. It occurs when warmer, less dense air rises, while cooler, denser air sinks.
Convective available potential energy
…In meteorology, convective available potential energy (commonly abbreviated as CAPE) is a measure of the capacity of the atmosphere to support the vertical movement of air that can lead to cloud formation and storms. As air rises in an atmosphere, it expands and cools. CAPE exists when a given mass of air (called an air…
