| 摘 要： | 利用常规气象资料和卫星、雷达、区域自动站等资料以及NCEP再分析资料,对2009年闽东北地区"莫拉克"台风的降水特征做初步分析.结果表明:台风"莫拉克"暴雨具有明显的"空心化"特征,有利的环境场条件、螺旋雨带上对流单体的不断影响、台风移动缓慢是此次台风暴雨的主要原因,而地形也有明显增幅作用.通过雷达回波基本反射率因子强...

| Abstract: | By using conventional meteorological,satellite,radar,regional automatic weather station,and NCEP re-analysis data,the characteristics of precipitation over the northeastern Fujian Province induced by the typhoon Morakot are studied.The results show that Morakot had an obvious hollow structure;the favorable environmental condition,the continuous impact of convective cells in the spiral cloud band,and the slow movement of the typhoon were the main reasons for the heavy rainfall,while the increasing role of to... |
