A global coupled air-sea model of shallow water wave is developed based on coupled ocean-atmospheredynamics.The coupling is realized through the air-sea interaction process that the atmosphere acts on theocean by wind stress and the ocean acts on the atmosphere with heating proportional to sea surface temperature(SST)anomaly.The equation is harotropic primitive one.Response experiments of coupling system arealso carried out SSTA in two categories of intensities.Compared with the results of AGCM simulation ex-periment in which only the dynamic change of air system is considered,it demonstrates that the air-seainteraction between the tropical ocean and the global atmosphere plays a very important role in the evolutionof climate system.The results of numerical simulation show that it is encouraging.
