What is the main reason a thunderstorm weakens in the dissipating stage?
Answer and explanation
Correct answer: The downdraft cuts off the updraft
During dissipation, the downdraft spreads across the storm’s inflow region and blocks the supply of warm, moist air. Without that buoyant inflow, the updraft weakens, cloud growth stops, and rainfall gradually decreases. Lightning or gusty winds may continue briefly, but the organized storm loses intensity.
