摘要
本文根据常规观测、ERA5 再分析资料、多普勒天气雷达、风廓线雷达、微波辐射计等资料,分析2022 年 7 月 25 日河北省中南部强对流天气主要受到多因素共同作用影响,可能包括特定地形因素、高温高湿气流的聚集、不稳定对流层结构等,导致局地短时强降水和雷暴大风.不同观测仪器提供的数据有助于深入了解天气系统演变过程及其成因,为对类似天气事件的准确预报和预警提供科学依据.
Abstract
Based on conventional observations,ERA5 reanalysis data,Doppler weather radar,wind profile radar,microwave radiometer and other data analysis,this paper finds that the severe convective weather in the central and southern parts of Hebei Province on July 25,2022 is mainly affected by the combined effects of multiple factors.This may include specific terrain factors,the accumulation of high-temperature and high humidity airflow,unstable tropospheric structures,leading to local short-term heavy rainfall and thunderstorm winds.The data provided by different observation instruments help to better understand the evolution process of the weather system and its causes,providing a scientific basis for the accurate forecasting and early warning of similar weather events.
