摘　　要：利用L波段探空雷达数据,分析了安庆2011—2020年逆温基本特征。结果表明,08:00、20:00逆温层平均出现的层数分别为1.9、1.5层,发生的频率分别为85.4%、79.7%。接地逆温发生的频率低于脱地逆温。统计期间内逆温出现的频率呈缓慢上升趋势。接地逆温层顶平均高度为222 m,08:00接地逆温层厚度大于20:00逆温层厚度,第一脱地逆温层起始高度及层顶高度的变化区间跨度大,厚度是接地逆温层厚度的1.6倍。逆温强度有微弱上升趋势并呈现明显的季节变化,夏季逆温强度小、次数少,冬季强度大、次数多。Using L-band radiosonde radar data,the basic characteristics of temperature inversion in Anqing from 2011 to 2020are analyzed.The results showed that the average number of inversion layers at 08:00and 20:00 was 1.9 and 1.5,respectively,and the frequency of inversion layers was 85.4%and 79.7%.The average height of the ground inversion layer was 222 m,and the thickness of the ground inversion layer at 08:00 was greater than that at 20:00.The variation range of the initial height and the top height of the first de-earth inversion layer was large,and the thickness was 1.6 times that of the ground inversion layer.The inversion intensity showed a slight upward trend and showed obvious seasonal variation.The inversion intensity was small and less frequent in summer,while the inversion intensity was large and more frequent in winter.
