摘要：

本文用PSU/NCAR中尺度模式MM4对黑潮暖流海域海洋边界层大气的斜压性对我国东南沿海地区局地环流及天气影响的数值模拟分析表明:在有利的大尺度背景风场向岸东风的作用下,我国东南沿海地区夜间可以有海岸锋生成,黑潮暖流影响锋生强度,并使沿海岸一带区域夜间降水增大。

In this paper, PSU/NCAR mesoscale model, MM4, is used to investigate the effects of the Kuroshio Current induced baroclinity on the regional circulations and weather over the southeastern China. The numerical results indicate that under the favorable large scale weather condition, the onshore wind field, the coastal frontogenesis can be seen during nighttime along the southeast coast of China. The intensity of the coastal front is influenced by the Kuroshio Current, and precipitation along the coastal zone will, therefore, increase due to the coastal frontogenesis.
