True/False Exam Questions 30. 31. 32. 33. 34.

The appearance of a downdraft marks the end of the mature stage of a thunderstorm. In a multicell storm, each of the cells is always in the same stage of development. A supercell storm consists of a single rotating updraft. Conditional instability is a favorable condition for thunderstorm formation. The atmospheric conditions that promote the formation of severe thunderstorms tend to prevent many smaller ones from forming. ....
