D)Coriolis forces

Question

Quizplus · Accepted Answer

The release of latent heat by condensation increases the vertical instability by warming the air and making it less dense, leading to buoyancy and upward motion. This is a key process in thunderstorm development. A low pressure aloft or a jet stream aloft may provide favorable conditions for thunderstorm development, but do not directly increase the vertical instability within the storm. Coriolis forces are not relevant to the initiation of thunderstorms.
