Question

Quizplus · Accepted Answer

B) In the Northern Hemisphere, the surface air moving from 30 to 60 degrees latitude generally moves from southwest to northeast (not northeast as stated, but the general concept of air movement and storm formation is correct). This air is relatively warm and moist and encounters colder air moving southward, leading to the formation of stormy regions, particularly at the polar front near 60 degrees latitude.
