摘要
为了准确获取气温的垂直变化特征,选用2008—2012年的TLogP探空数据,采用回归分析等方法,研究了中国地理区域内气温直减率和逆温层的时空分布特征。结果表明:华中、华南和华东区域的气温直减率年均值较高,其他区域较低;西南、西北、东北和华北区域的气温直减率在夏季和冬季较高,而华中、华南和华东区域只在冬季较高;中国境内的逆温层一般出现在春季和冬季,且早上比晚上多;逆温层在华南和华东区域出现次数较多,而在西南区域较少;在西南和西北区域,近地表2km以下大气中一般具有2个逆温层,而其他区域一般具有3层。
To acquire the characteristics of vertical temperature variation,by using TLogP sounding data between 2008 and 2012 and selecting regression analysis method,the temporal and spatial distribution characteristics of temperature lapse rate and inversion layer in China were analyzed.The resultsshowthatthe annual mean value of temperature lapse rate is high in central China,southern China and eastern China but low in other areas.The monthly mean value of temperature lapse rate is high in summer and winter in southwestern China,northwestern China,northeastern China and northern China but itishigh in winter in central China,southern China and eastern China only.Inversion layer mainly appears in spring and winter in all districts,and the frequency in the morning is higher than it in the evening.High frequency of occurrence of inversion layer appears in southern China and eastern China,while low appears in southwestern China.There are commonly two inversion layers in southwestern China and northwestern China but three in other districts below 2 km.
