What characterizes the dissipating stage of a thunderstorm?

The dissipating stage of a thunderstorm is primarily characterized by the presence of strong downdrafts. At this stage, the lifting or updrafts that originally fueled the storm begin to weaken significantly. As the updrafts lessen, the precipitation that the storm has produced starts to fall, which enhances the downdrafts. These downdrafts can lead to a reduction in overall storm intensity, ultimately causing the storm to dissipate.

This stage is marked by a decrease in cloud height and a reduction in the overall thunderstorm activity as the storm's energy source is cut off. The cooling effects of the rain and downdrafts serve to stabilize the atmosphere, leading to the storm's weakening.

The other characteristics mentioned in the other options, such as strong updrafts and rapid growth of the cloud, are typical of the earlier stages of a thunderstorm, not the dissipating stage. Similarly, while thunderstorms do have various hazards, the dissipating stage itself is not characterized by all hazards, particularly since the intensity and severity of the storm are declining.
