摘　　要：采用区域海气耦合模式对１９９８年５～ ８月东亚近海海况进行了模拟研究。耦合模式模拟出了黑潮海流及其右侧的大尺度反气旋式涡旋，对南海表层海流的模拟也与实际基本相符，并模拟出了南海海流受季风影响较大的特点。模式也模拟出了伴随西南季风爆发及推进而发生的海温突增及暖水区北推过程。这为进行区域气候变化与区域海气相互作用问题的研究开辟了一条新途径。The oceanic elements at East Asian coastal oceans from May to August in 1998 are simulated by using a coupled regional ocean-atmosphere model developed in this Paper. The Kuroshio current and the large-scale anticyclonic vortex to its right are simulated by this coupled model. The simulated surface currents of the SCS which are greatly influenced by the monsoon are also basically consistent with the reality. The sudden increase of SST and the northward expending process of warm water region accompanied with the onset of summer monsoon are fairly modeled by the coupled model. This is a new way to study the issues of regional climate change and regional air-sea interaction.
