摘　　要：用一个水平二维模式对近海风暴流进行数值研究。选用西行、北上和西行转向三个模式台风路径。发现在台风后部沿轨迹右侧留有强的、稳定的、与台风同方向的“尾流”。在“尾流”右侧还伴有一个绕“水堆”的顺时针方向的涡旋。试验证实台风过境后主要增水区位于台风路径右侧。并指出海洋对缓慢移动的台风的响应更强。A two-dimensional horizontal model is employed for numerical studies of storm-induced currents in coastal seas. Three model typhoon tracks, westerly, northerly and turning northwestward arc selected. It is noteworthy that along the track a strong sustained wake current in the same direction with the typhoon is left behind the typhoon centre and on the right of the wake current is a clockwise vortex around a water pile. The fact that the water elevation area is located on the right of the tracks as shown by the results of the storm surge models is obvious. The results also indicate that the oceanic response to the slower translating typhoons is stronger.
