A SIMPLE AIR-SEA PLANETARY BOUNDARY LAYER MODEL WITH SPECIAL REFERENCE TO EKMAN CURRENTS Ⅰ——ON THE WINDS OVER SEA SURFACE AND THE OCEAN CURRENTS IN AN OCEAN OF INFINITE DEPTH

In this paper,special attention is paid to the analyses of the winds over sea surface and the currents in an ocean of infinite depth.With the aid of a simple air-sea planetary boundary layer model,the physically diagnostic analyses of the wind and the current profiles,the surface wind stress,the dissipation of energy and the Ekman pumping in the atmosphere as well as in the ocean under the actions of atmospheric large scale baroclinic disturbances are made in detail for an ocean of infinite depth.Strong emphasis is laid upon the effect of the atmospheric baroclinicity.Some theoretical results thus obtained is in agreement with the observations.
