Question

Quizplus · Accepted Answer

A seasonal north wind blowing along the west coast of a landmass in the Northern Hemisphere would cause the Ekman transport to move surface water offshore, leading to the upward movement of cold, nutrient-rich deep water to the surface. This process is known as upwelling. In the Northern Hemisphere, winds blow clockwise around a high-pressure system, so a northerly wind blows parallel to the shore in the summer, inducing upwelling.
