What is one characteristic of the cumulus stage of a thunderstorm?

The cumulus stage of a thunderstorm is primarily characterized by considerable updrafts and the building phase of the storm. During this stage, warm, moist air rises, cooling as it ascends, which leads to condensation and the formation of cumulus clouds. This process is vital as it represents the initial development of the thunderstorm. The strong updrafts are a sign that the storm is gaining strength, and this stage typically precedes the onset of precipitation.

Understanding this stage helps in recognizing the progression of thunderstorms, which is essential for predicting further developments and potential hazards associated with severe weather.
