摘要：

本文根据1976—1983年12-3月的卫星云图,对生成于澳大利亚卡奔塔利亚湾的十余次热带风暴过程做了研究。发现于奔塔利亚湾台风的形成过程有惊人的一致性。当赤道西风强烈爆发时,无数东西向云带受伊里安岛山脉和约克角半岛的地形强迫影响,作气旋性旋转进入原已存在于卡奔塔利亚湾的热带忧动中,发展成为螺旋状云带。同时在中等一弱冷锋迫近的配合作用下,扰动加强成为卡湾台风。对于生成卡湾台风的过程以及与泰国湾的对比分析,也从反面证实了上述十湾台风生成的环流条件。

This paper analyses the processes of more than ten tropical cyclones occurring in the Gulf of Carpentaria , Australia , based on the satellite photographs of December-March, 1976-1983.It is shown from analyses that the processes of formation of tropical cyclones over the Gulf of Carpentaria are surprisingly similar to each other. when the west wind in the equator bursts, many east-west oriented cloud belts rotate cyclonically,entering into the tropical disturbances which have existed in Carpentaria already,and developing into spiral Cloud belts because-of the geographical forcing by the mountains of Irian Island and the York Cape Peninsula. Furthermore,since the mild or weak cold front comes nearer, the disturbances strengthen and become the typhoon over the Gulf of Carpentaria. The circulation conditions for the formation of the typhoon over the Gulf of Carpentaria are also proved by its comparison with that over the Gulf of Thailand.
