Which stage of thunderstorm development is characterized by updrafts and downdrafts caused by falling precipitation?

• A. Cumulus stage
• B. Dissipating stage
• C. Mature stage
• D. Precipitation stage

Answer: (C)

The stage when air is still rising strongly but rain and other precipitation are starting to fall is the mature stage. During this phase, updrafts continue to lift warm, moist air into the cloud while downdrafts develop as falling raindrops (and any hail) drag air downward and cool the surrounding air. The coexistence of these rising and sinking motions is what drives the storm to its peak, producing heavy rainfall, thunder, and often strong winds.

The other stages fit different patterns: the cumulus stage involves only updrafts with no precipitation yet; the dissipating stage is dominated by downdrafts as the updrafts weaken and the storm fades. A term like precipitation stage isn’t part of the standard sequence, and the mature stage is the one that specifically features both updrafts and downdrafts driven by falling precipitation.
