Structure of Coastal Upwelling on a Sloping Bottom

Document Type: Proceeding Paper

Part of: Hydraulic Engineering

Abstract:

A large eddy simulation of coastal upwelling on a sloping bottom is carried out. The structure of the upwelling consists of a persistent primary front, a temporary secondary front which forms the nose of a top unstable layer, and a trailing mixing zone. Baroclinic instability occurs at the primary front and develops into large, predominantly 2-D waves and eddies. The computed results are compared with past experimental data.
