In which stage of a thunderstorm does rain, down rushing air, and increased winds occur?

The mature stage of a thunderstorm is characterized by the presence of rain, down rushing air, and increased winds. During this phase, the storm has developed fully, with strong updrafts that contribute to the formation of large clouds and precipitation. As the updrafts continue to lift moisture high into the atmosphere, the cloud becomes heavy enough to release its water content, resulting in rain. The strong downdrafts of air, known as microbursts, can also occur during this stage, leading to rapidly changing wind directions and an increase in wind speeds near the surface. This combination of rainfall and turbulent winds is a hallmark of the mature stage, making it a critical period for weather phenomena associated with thunderstorms.

In contrast, the dissipating stage involves a decrease in rainfall and storm intensity, while the formation and initial stages focus on the development of the storm itself and lack the characteristics of significant rain and strong winds.
