What shape characterizes the dissipating stage of a thunderstorm?

During the dissipating stage of a thunderstorm, the shape characterized is typically referred to as an anvil shape. This shape forms due to the upper-level winds spreading out the ice and water particles in the anvil cloud, which extends horizontally. As the storm loses its intensity, the rising air currents weaken, and the precipitation begins to decrease, leading to the characteristic flattening at the top, resembling an anvil.

Understanding the formations of thunderstorms is essential in aviation and UAV operations, as they significantly influence weather conditions. The anvil shape specifically indicates that the storm is entering its final phase, providing vital information to pilots and operators regarding the likelihood of turbulence or changing weather patterns as the storm fades.
