摘要：

利用浪潮流耦合模式FIOCOM的2018年7月上半月琼东上升流预报产品，与全球混合坐标模式HYCOM数据，以及MW_IR和OSTIA两类卫星数据融合产品进行比较分析。研究结果表明： FIOCOM模式较好地刻画了2018年7月上半月琼东上升流区域的位置以及该区域海洋表层及次表层冷水上翻和离岸流显著等陆架区上升流特征。4类产品温度场的比较分析表明： FIOCOM模式对2018年7月上半月琼东上升流的预报准确性优于HYCOM预报结果。

The upwelling forecast product along the east coast of Hainan Island in the first half of July 2018 simulated by the wave-tide-circulation coupled ocean model FIOCOM is compared with HYCOM and the fusion products of MW_IR and OSTIA. The results show that FIOCOM could capture the location of upwelling area east of Hainan Island in the first half of July 2018 as well as the features of the shelf upwelling such as the anomalous upwelling of cold water in the surface or subsurface sea and the significant offshore current in the area. The comparative analysis of temperature field of the four kinds of products reveals that FIOCOM is more accurate than HYCOM in forecasting the upwelling east of Hainan Island in the first half of July 2018.
