【摘要】 分析了0509号台风的移动路径、强降水分布及物理量场分布,重点分析台风在安徽突然转向东北和强降水不在中心附近而是偏于中心东北侧的原因。结果表明:副高突然南落及200hPa辐散偏向台风中心右侧是台风在安徽转向进入江苏的原因;台风进入西风带以后没有明显的冷空气侵入;台风进入山东前,半岛大暴雨是由台风右侧东南急流和切变线引起,而台风进入山东境内时,鲁北、鲁中强降水由台风倒槽引起。更多还原

【Abstract】 The characteristics of typhoon NO. 0509 moving course, heavy rain and physical quantities fields have been analysed, the importance of which is the reason of typhoon abrupt turning northeastward in Anhui Province and heavy rain over the northeast of the typhoon center. The following meaningful conclusions are given which show that: the reasons of typhoon abrupt turning are the subtropical high pressure moving southward and divergence fields of 200hPa locating the right of the typhoon center; there is no obvious cold air invading Shandong after the typhoon entering westerly belt; the southeasterly jet of typhoon and shear caused the Shandong peninsula great rainfall before the typhoon entering Shandong. But after the typhoon entering Shandong, the typhoon inverted trough brought the rainfall in north and center to Shandong.更多还原
