摘要
本文首先通过分析廊坊市辖区内9个气象观测站的雷暴历史资料,得出雷暴日统计特征;其次通过分析廊坊市雷暴日环流形势及配置特征,对廊坊市雷暴日高度场、温度场和海平面气压场进行环流分型;再次是通过对廊坊市周边3个站的探空资料进行分析,得出雷暴发生日8:00 Tlog P图各个物理量的差异。从而揭示廊坊市雷暴日环流特征和各个物理量的指向性,总结雷暴发生前气象规律,为廊坊市雷暴灾害的预报和服务提供参考。
Through analysis on thunderstorm history data from 9 weather observation stations in Langfang City,the statistical characteristics of thunderstorm days were concluded. The thunderstorm day＇s circumfluence types of height field,temperature field,sea level pressure field were conducted by analyzing the cireumfluenee situation and configuration characteristics of thunderstorm days in Langfang City. The radiosonde data of 3 nearby stations were analyzed to educe differences of physics quantities of TlogP chart on 8：00 of thunderstorm days. The eircumfluence characteristic and the directionality of physics quantities in thunderstorm days were revealed, weather law before thunderstorm was summarized, so as to provide references for forecast service of thunderstorm disaster in Langfang City.
