Abstract:

The characteristics of polar atmosphere boundary layer have remarkable response to the flux variation at ocean-air interface in polar region.Both Ocean-Atmosphere-Ice Interactions (OAII)research and the Surface Heat Budget of the Arctic Ocean(SHEBA)project show that the study of structure and physical characteristics of polar atmosphere boundary layer is very im- portant for learning ocean-air interface flux and polar environmental change.The research on the polar ocean-air interface flux and the polar atmosphere boundary layer is briefly introduced in this paper and the preliminary numerical simulations are carried out by using a simple one- dimensional K-closure model and an Arctic single-column model,respectively.The output data from the European Centre for Medium-Range Weather Forecast(ECMWF)model are used as the lateral forcing in the simulation and the results from the simulation are analyzed and com- pared with the SHEBA data in the paper.
