摘　　要：基于垂向混合坐标系统的海洋模式HYCOM建立了全球大洋气候态环流场。在此基础上与前人研究工作进行对比,分析和讨论了全球风生大洋环流场的季节变化情况。从模拟结果看该模式具有较好的模拟能力,可以合理地模拟南极绕极流、赤道流系、黑潮和湾流等世界各主要大洋流系。从断面温度场、流函数分布和断面流量场等分析显示:南极绕极流堪称世界最强流,湾流整体强于黑潮,3者都具有夏季增强、冬季减弱的特点。HYCOM模式在国外的研究方兴未艾,而在国内的应用尚处在起步阶段。本文通过对该模式的介绍和结果分析,向读者推荐使用该模式。Based on the hybrid coordinate ocean model （HYCOM）, the climatically global ocean current system is established. Comparea with the former study, this paper analyzes and discusses the seasonal variations of the wind driven circulation in global ocean. The results show that this model can reasonable reproduce the equatorial currents, the Kuroshio Current, the Gulf Stream and the other main currents in global ocean. By analyzing the temperature sections, stream functions and volume transport sections, the results show that the Antarctic Circumpolar Current is the strongest current in the world oceans, the Gulf Stream is stronger than the Kuroshio Current, and all of them are stronger in summer and weaker in winter. The study on HYCOM is very famous in foreign countries, but the application to HYCOM is still in the starting stage in our nations. The goal of this paper is to recommend this model by verify its numerical results.
