Which atmospheric-driven effect causes enhanced coastal upwelling currents along western continental edges at mid lats?

💡 Explanation

When wind blows parallel to a coastline, Ekman transport causes surface water to move 90 degrees to the wind direction because of the Coriolis effect, resulting in divergence of water away from coast and upwelling. Therefore Ekman transport divergence results, rather than other choices that don't directly explain coastal upwelling along the west coast.
