In meteorology, what does 'CAP' stand for?

In meteorology, 'CAP' stands for Convective Available Potential Energy. This term refers to the amount of energy available for convection, which is the process by which warmer, less dense air rises and leads to the formation of clouds and precipitation. CAP quantifies the potential for the atmosphere to support convection and ultimately plays a crucial role in determining storm development and intensity.

Understanding Convective Available Potential Energy is essential for meteorologists, as it helps in predicting severe weather events such as thunderstorms and tornadoes. A higher CAP indicates a greater potential for storms to form, as there is more energy available for the air to rise and generate convective activity. This concept is particularly important in severe weather forecasting, as it aids in identifying conditions conducive to the development of severe thunderstorms.

The other options, while related to atmospheric phenomena, do not correctly define 'CAP' in the context of meteorology.
