Ekman Downwelling (Hydroform Type)

Component: Hydroform

Unique Identifier: 654

Hydroform Class Current
Hydroform Ekman Flow
Hydroform Type Ekman Downwelling


Description
Definition Downwardly-directed current, resulting from either the convergence of water masses or from the convergence of a water mass with a coastline. At this convergence, gravity will force water into a downwelling, which will carry surface water to greater depths. In the nearshore, the circulation will take the water to the shallow bottom and then move seaward. In deeper waters, the downwelling will carry water to a depth determined by energy dissipation and relative density considerations; the maximum downwelling depth can be into the abyssalpelagic zone.
