Thunderstorms and large cumulonimbus clouds are characteristic of:
A) all polar air masses.
B) stable air.
C) unstable air.
D) isothermal lapse rates.

Question

Quizplus · Accepted Answer

Thunderstorms and large cumulonimbus clouds are caused by unstable air, which is characterized by rapid upward movement of warm air and the formation of convective clouds. Polar air masses do not necessarily lead to thunderstorms and cumulonimbus clouds, and stable air typically produces clear skies or only small and short-lived clouds. Isothermal lapse rates refer to a situation where temperature does not change with altitude, and are not directly related to thunderstorms or cumulonimbus clouds.
