Question

Quizplus · Accepted Answer

The energy of a mid-latitude cyclone comes from the contrast between sinking cold air and rising warm air. As the warm air rises and the cold air sinks, the resulting pressure gradient force generates winds which contribute to the energy of the cyclone. Clouds, greenhouse effect, and ocean water may play a role in the development and maintenance of the cyclone, but they are not the primary source of energy. Earth's interior is not relevant to the formation of a mid-latitude cyclone.
