【摘要】 <正> 台风是夏、秋季对我国东南部天气有重大影响的热带天气系统,西北太平洋台风、强台风平均每年有6.6次登陆我周。影响台风的形成和移动路径的因素很多,其中海水表面的温度(以下简称表面海温)也是重要因素之一。海水热容量大,具有很大的热惯性,在中、长期天气预报中,表面海温的影响是一个必须考虑的因素。本文对在我国(台湾省暂时没有统计在内)登陆台风的盈年和亏年的北太平洋表面海温场进行分析,并进一步对台风季节前期的表面海温场进行相关分析,指出了表面海温的变化对台风移动路径有影响的关键海区,再取一些相关系数位高的点,作出检验方程。更多还原

【Abstract】 According to the analysis of surface water temperature departure in the North Pacific from 1949 to 1974, corresponding to the number of typhoon landed in China were two types of surface water temperature departure fields wholely contradict to each other. To the year with more typhoon landed in China was the Typ Ⅰ of surface water temperature field, namely the type of warm the north and cold in the south, and to the year with less typhoon was the type Ⅱ, or cold in the north and warm in the south.Both types of departure fields were set up around March and began to disappear in November. From March to July was the stage of developing and temperature increasing while from August to November was the stage of weakening and temperature decreasing.The changes of surface water temperature prior to the typhoon season had evident effects on, the typhoon tracks in some areas which corresponded to the areas with strong currents, The degree and arera subjected the cffects had both temporal variations.更多还原
