What is a characteristic of downdrafts during the dissipating stage?

During the dissipating stage of a thunderstorm, downdrafts play a significant role in the storm's behavior. One characteristic of this stage is that downdrafts dominate and can cut off the inflow of warm, moist air that is necessary for storm development. As a storm reaches the dissipating stage, the updrafts weaken and eventually stop, leading to a reduction in the vertical movement of air necessary to sustain the storm. This change is primarily due to the overpowering downdrafts, which signify that the storm is losing its energy and moisture supply.

In this stage, the strength of the downdrafts indicates a shift in the storm's dynamics, where the downward flow of air becomes the primary force influencing the weather conditions. This results in a funneling effect that can effectively stifle any remaining upward motion, leading to a gradual end to the storm. Understanding this characteristic helps in recognizing the lifecycle of thunderstorms and their potential hazards, particularly in relation to flight operations.
