| 摘 要： | 分析热带西北太平洋和南海的表层至100m的水温变化与热带气旋活动的关系。得出:(1)海洋热含量正距平年热带气旋偏多,反之偏少。(2)热带西北太平洋西部热含量增加时,副热带高压脊点偏西,移入南海的热带气旋频数增加,反之减少。(3)因热带东、西太平洋水温变化反相,南海水温变化与热带东太平洋同位相,故从太平洋移入南海的热带气旋与在南海生成的热带气旋频数的变化趋势近于相反。

| Abstract: | The relationship of heat content in the tropical Northwest Pacific, South China Sea and the movement of tropical cyclone which generated in these oceans was analysed. It was shown that : 1. When yearly anomaly of heat content was positive, the frequency of tropical cyclone increased, otherwise it decreased; 2.When heat content increased, the ridge point of subtropical high moved more westly, and frequency of tropical cyclone moving from Pacific into South China Sea increased, otherwise it decreased; 3. Because variation of SST in west Tropical Pacific and East Tropical Pacific was opposite,while the variation of South China Sea and the East Tropical Pacific was the same, so the frequency of tropical cyclone which moved from the Pacific into South China Sea was almost opposite. |
