| 摘 要： | 利用FY-2气象卫星的TBB资料对登陆华东地区的台风进行了对流非对称结构的分析。不同象限的对流分析显示,在台风登陆的-24—6 h过程中,其南侧的对流始终强于北侧,西侧的对流在登陆至8 h之前强于东侧,之后两者的对流相对强弱发生变化。台风对流的非对称分布,一部分是由于环境垂直风切变和台风移动造成的,还有一部分是由于台风登陆过程相关象限对流受限引起的。此外,华东沿海的地形抬升作用也有利于台风东侧对流的产生和加强。对比华南登陆台风的非对称对流分布特点,发现导致两者明显不同的原因主要在于台风登陆过程的路径与海岸线的相对夹角,以及台风东侧的不同地形。 |

| Abstract: | The asymmetric distribution of convection associated with tropical cyclones making landfall along the east China coast was studied with FY-2 geostationary meteorological satellite data TBB.The convection in various quadrants of TC was examined during the period of-24 to 6 h relative to landfall.The convection to the southern side of the TC showed much intense than that to the northern side during the whole landfall period.The convection to the western side of TC was stronger than that to the eastern side be... |
