广西防城港市一次冬季连续性大到暴雨过程成因分析OA
Analysis of Synoptic Cause of the Continuous Rainstorm Process in Guangxi Fangchenggang in the Winter of 2009
利用常规气象资料和1°×1°NCEP6小时再分析资料等,分析广西防城港市一次冬季连续性暴雨过程发生的原因.结果表明:①这次冬季强降水是在高空槽、副高边缘、西南急流、冷空气和切变线等多个系统的配合下产生的；②有利的500 hPa环流形势是造成暴雨的必要前提；③暴雨区内的水汽供应主要是边界层内的水汽通量辐合造成的；④冷空气与西南暖湿气流形成的切变辐合在边界层产生明显的锋生作用.
Based on the conventional meteorological data and 1 ° × 1 ° NCEP 6 hour reanalysis data, synoptic cause of the continuous rainstorm process in Cuangxi Fangchenggang were analyzed. The conclusions are as follows: the rainstorm occurs with multiple systems of trough, the edge of the subtropical high, southwest jet, cold air and shear line; the favorable upper air circulation at 500 hPa is the essential factor; the conver gence of vapor flux in the …查看全部>>
