What are the three stages of a thunderstorm?

1. Cumulus, Dissipating, and Dry

2. Cumulus, Mature, and Dissipating

3. Active, Dormant, and Mature

4. Cumulus, Stable, and Final

The correct answer is: Cumulus, Mature, and Dissipating

The three stages of a thunderstorm are indeed Cumulus, Mature, and Dissipating, which reflects the progression of a thunderstorm's life cycle. In the Cumulus stage, warm, moist air rises and cools, leading to the formation of cumulus clouds. This stage is characterized by the initial development of convection currents and the growth of the cloud as moisture continues to rise. During the Mature stage, the thunderstorm reaches its peak intensity. Updrafts and downdrafts are present, with strong winds, heavy rain, and possibly hail. This stage is when the storm produces the most severe weather and why it is vital for aircraft dispatchers and pilots to monitor. Lastly, the Dissipating stage occurs as the storm begins to lose its strength and moisture. Downdrafts dominate, which leads to a decrease in precipitation and ultimately the storm's end. Understanding these stages is crucial for flight safety and weather-related decision-making. The other options do not accurately capture the distinct phases of thunderstorm development as recognized in meteorology.
