Comparative analysis of the circulation and structure characteristics with different types of plum rains in the North of Zhejiang Province(浙北地区不同梅雨年型环流结构差异对比分析)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2014
通过客观分析资料和梅汛期降水量实况,对2005~2013年浙北地区梅汛期降水进行分型,对比分析不同年型大尺度环流及结构特征差异.结果表明:100 hPa上多雨年南亚高压要强于少雨年,当南亚高压主体偏西时,浙北地区降水偏多.500 hPa上多雨年较少雨年588脊线位置明显偏南,少雨年588线的西伸脊点伸展到菲律宾一带,多雨年588线西伸脊点则明显偏东.850 hPa切变线及低空西南急流位置偏南,导致西南急流携带的水汽集聚在浙北地区上空,急流左侧上升运动强,为强降水创造了有利条件 ...
