平凉市低空大气逆温特征分析

Characteristic Analysis of Low-altitude Atmospheric Inversion Temperature in Pingliang

根据崆峒气象站探空资料,分析平凉市2013—2017年逐日08:00和20:00逆温分布特征。平凉市低空大气温度层结全年以弱稳定为主,一年四季都有逆温层,逆温强度平均为1.4℃/100m,冬季是逆温特征最显著季节,强度最强,逆温发生频率最高,夏季强度最弱,频率最低。

Based on the sounding data of Kongtong meteorological station,the characteristics of inversion temperature distribution in Pingliang from 2013 to 2017 were analyzed.The low-altitude atmospheric temperature stratification in Pingliang was mainly weak and stable.There were inversion temperature layers in all seasons.The average of inversion temperature intensity was 1.4℃/100 m.Winter was the most significant season with the strongest intensity and the highest frequency of inversion temperature.The intensity was the weakest and the frequency was the lowest in summer.
