中文摘要:
      本文根据大陆上此较完善的地面观测资料,着重地对1953—1956年四次较强的登陆台风,此较细致地分析了台风中的气压、风、降水量和中心附近的气象状况的分布以及其相互联系.主要的结果如下:(i)台风范围内气压分布的特点随其移动方向的改变有显著不同.台风低压的填塞为其半径的函数,而且其六小时填塞率和当地气压日变化一致.(ii)台风范围风速的分布不仅和其气压分布相适应,而且受到海陆、地形的显著影响.地面风的辐合分布和台风降水分布的配合较好.(iii)台风登陆后的降水分布大致按其发展程度分为三种类型:对称型、侧偏型、对锋面型.(iv)台风刚刚登陆,其中心附近可有两种截然不同的天气状况:一类中心天气晴晴朗平静,一类中心狂风大雨.总的来说,登陆台风的地面结构一方面从东风带到西风带发生显著的变化,一方面受到海陆、地形的重大影响.
英文摘要:
      Based on the comparatively complete surface data}we have analyzed the dishibutions of presure, wind, rainfall weather as well as their interrelations of four intense typhoons which invades the continents. The main results are as follows:(1)The pressure distribution within a typhoon varies considerably with its direction of motion. The filling of a typhoon is a function of its radius.(2) The wind distribution within a typhoon is considerably influenced by the earth's topography. The distribution of convergence agrees well with the rainfall distribution.(3) After invading the continent the rainfall distribution may be classi-fled into three types, namely symmetrical type, asymmetrical type and accoiding to the stage of its development.(4) Just after invading the continent there are two entirely different types of weather near the center of typhoon, namely clear and quite weather and violent rainfall. In conclusion, the structure of typhoon changes considerably when it enters the westerlies from the easterlies. On the other hand its structure is influenced appreciably by the land and sea and the earth's topography.
