What does thunderstorm mean?
A thunderstorm is a storm accompanied by thunder and lightning, often with heavy rain, hail, or strong winds. In ordinary conversation, the word describes a weather event and may imply that the storm is powerful, noisy, or disruptive. Because thunder is the sound produced by the rapid heating and expansion of air along a lightning channel, the presence of thunder distinguishes a thunderstorm from other kinds of rain or wind storms. The word also has a figurative use for a sudden and violent exchange of anger, criticism, or argument. Expressions such as “a storm of complaints” and “a thunderstorm of protests” treat the verbal conflict as a storm breaking violently over the participants. Thunderstorms are common in many regions, particularly where warm, moist air rises into cooler air, though their frequency and severity vary seasonally and geographically.
