Which mechanism causes surface ocean gyres' intensification along western continental coasts?

💡 Explanation

When surface water flows towards a coast, Ekman transport causes convergence that is then deflected by western boundary currents due to the Coriolis effect because of Earth’s rotation, increasing the gyre's speed and concentrating water. Therefore Ekman transport convergence results, rather than alternatives that don't explain flow speed changes along coasts.
