摘　　要：MM5数值产品作为大气强迫,利用冰-海洋耦合模式模拟2003～2004冬季渤海海冰演变过程。与海冰遥感、海洋站监测资料等实测资料相比,初冰日和终冰日和观测数据比较接近,模拟海冰各个发展阶段主要分布特征和MODIS遥感图像相似,但模拟的海冰厚度与辽东湾93平台、202平台的冰厚观测数据相比存在较大出入,说明该模型还有待改善。总体上看,冰-海洋耦合模式基本具备模拟渤海海冰季节演变过程的能力。We use the ice-ocean coupled model, which is driven by simulated atmospheric forcing of MM5, to simulate the seasonal variation of 2003/2004 ice cover in the Bohai Sea. And the simulated result is compared with the satellite remote sensing data and the station observation data. The simulated ice freezing date ice free date and every ice period important characteristic is good. The simulated ice thickness is thicker than that observed on oil platform JZ-93 and JZ20-2. It＇s found that the coupled ice-ocean model can simulate the seasonal evolvement of the sea ice in the Bohai Sea.
