摘　　要：黑潮是一支高温、高盐的西边界暖流,也是北太平洋副热带环流的重要组成部分;同时,黑潮也是影响潜艇航速、定位和行动隐蔽性的重要海洋环境现象。黑潮将高温、高盐的海水输送至东海,会对我国东部沿海地区的气候产生重要影响。利用ROMS模式以较高的分辨率模拟东海海表面和PN断面温度结构的季节变化特征,并结合WOA13数据进行对比分析,为开展东海黑潮相关研究提供基础。结果表明ROMS模式对东海黑潮具有较好的模拟效果,模式模拟的海表面温度的季节变化趋势与WOA13数据较为一致,冬、春季黑潮路径较为明显;同时,模式较好地模拟了PN断面温度结构的季节变化特征,流核结构明显。Kuroshio as a high temperature,high salt,west boundary warm current,is an important part of the north Pacific subtropical circulation.At the same time,kuroshio is a kind of important marine environmental phenomena which can influence speed.Location and covertaction of submarine Kuroshio flows into the east China sea with high temperature,high salt water.Kuroshion in East china sea have an important influence on the climate of the east coast of China.By making use of the Regional Ocean Modeling System（ROMS）and data of WOA13（World Ocean Atlas 2013）,the seasonal variation characteristics of sea surface in east china sea and PN section temperature structure are simulated in order to provides the basis for the related research of Kuroshio.Results shows that ROMS have a good simulation on the east China sea Kuroshio,the simulation of the SST seasonal variation agrees with the result of the WOA13,and the route of the Kuroshio in winter and spring is clear.At the same time,the model can simulate the seasonal variation characteristics of PN section temperature structure.
