河北一次春季回流暴雨过程及其热力结构分析

Thermodynamic Structure of a Returning Flow Heavy Rain in Spring over Hebei Province

摘要: 利用常规观测资料和NCEP 1°×1°再分析资料,采用天气动力学诊断方法,对河北中南部春末一次回流暴雨的风场、水汽、热力条件进行了详细分析。结果表明:(1)此次大暴雨发生在地面冷锋后部、近地层超低空急流产生回流的稳定气团中,85

Abstract: Based on conventional weather maps and NCEP 1°×1° reanalysis data,dynamic diagnosis is used to analyze the wind field,water vapor and thermodynamic conditions of a returning flow heavy rain event in late sprin
