Fluxes of momentum,heat,radation and water at the air-sea interface dhve the ocean circulation and determine the coupling between the atmosphere and the ocean.A reliable determination and analysis of these flux fields and wind fields are therefore essential for understanding the role of the oceans in climate. The goal of this paper is to introduce some atmospheric kinetic and dynamic eiements, calculative methods, research history and the data for analysing global climate and interaction between the atmosphere and the ocean. The comprehensive ocean-atmosphere data set(COADS)is the most complete data set available for the global oceanic regions up to now. The examples of calculation and analysis of wind stress and wind fields in the world oceans on the basis of the wind data derived fron COADS are given at last.
