摘　　要：利用妈祖·海流海洋数值模式(MaCOM)构建了一个水平分辨率为1/48°的西太平洋数值模拟系统,使用该系统开展了3个数值模拟敏感性试验,分析了有无潮汐、更换大气驱动场对黑潮流系上7个关键断面热输送数值模拟能力的影响。分析结果表明潮汐对于黑潮热输运的影响力约是更换大气强迫场的两倍。台风对所经过的黑潮断面热输运能力有显著的影响,但仅局限于中心附近海域和台风经过期间,未发现类似近惯性振荡波在时空上的延续。在高纬和浅海区域,体积输运的演变规律和热输运之间存在一定差异,热输运的季节变化略平缓。MaCOM模拟的黑潮主流热输运年均值与季节变化趋势和再分析数据以及前人的研究基本一致。Using the Mass Conservation Ocean Model(MaCOM),a numerical simulation system with a horizontal resolution of 1/48°was constructed in the western Pacific.Three sensitivity experiments were carried out using this system to analyze the effect of tides and different atmospheric driving fields on the heat transport on seven key sections of the Kuroshio Current.The analysis results show that the influence of tides on the heat transport of the Kuroshio Current is about twice that of the replacement of atmospheric forcing fields.Typhoons have a significant impact on the heat transport capacity of the Kuroshio Current section where they pass through,but its impact only limited to the central area and during the passage period.No features analogous to near-inertial oscillation waves were found.There are some differences between the evolution of volume transport and heat transport in high-latitude and shallow sea areas.However,the seasonal variation of heat transport is slightly flat.The annual average and seasonal variation of the main stream heat transport of the Kuroshio Current simulated by MaCOM are basically consistent with reanalysis data and previous studies.
