| 本文利用1960～1994年台风年鉴资料,定义进入30°N以北、125°E以西的热带气旋为影响北方热带气旋.根据定义普查,35年中共有63个造成北方暴雨,年均1.个.我们把影响北方暴雨的63个热带气旋根据后期移动路径的不同划分为6类,以500hPa高空图为基础,分析西风带和副热带系统的特征,给出了各类热带气旋在影响北方前24h副热带和西风带系统的异同. |
| Making use of the year-book data of the typhoon between 1960-1994, we define the tropical cyclone entering the area north to 30°N and west to 125°E as the affecting-north tropical cyclone. According to the definition, we can find there are sixty three tropical cyclone altogether in thirty five years have caused northern storm. The annual mean is 1.8. We’ll classify the sixty three tropical cyclone into six types by later period moving path. Based on the 500hpa aerogram, we’ll analyse the characteristic of the westerly and subtropical system and show the similatities and differences of the subtropical and westerly system while 24 hours before every kind of storm surge affecting the north. |
