| 摘 要： | 本文对1974—1983年夏季印缅槽活动进行普查后指出,夏季印缅槽属于印度季风槽的一部分,它的活动受南海毗邻地区热带天气系统所制约。在南半球越赤道气流进入孟加拉湾和中南半岛所形成的西南季风潮过出后期,往往是印缅槽形成的良好时期。初夏印缅槽活动与华南前汛期的暴雨有较好的相关。

| Abstract: | In this paper, YIN-MIAN trough during summer in the years of 1974-1983 are analysed. It is found that the YIN-MIAN trough is a branch of Indian monsoon trough and its activity is restricted by the tropical weather systems over the South China sea and adjacent area.The favorable condition for the YIN-MIAN trough genesis is at the late regime of monsoon surges which originate from the cross-equatorial current from the Southern Hemisphere and prevail over the Bay of Bengal and Indo-China Peninsula. It is shown that there is close relationship between the activity of the YIN-MIAN trough and the haevy rainfall over the South China in the early rainy season. |
