成都地区大气边界层逆温特征分析
Characteristics of temperature inversion in atmospheric boundary layer in Chengdu area
摘要
Abstract
For the problem of the pollution meteorological conditions influencing atmospheric environment,struc-ture distribution characteristics of temperature inversion in Chengdu were analyzed based on temperature of sound-ing data from 2010 to 2012.The results show that surface inversion during 2010-2012 in Chengdu area as a whole has the highest frequency,the largest thickness and the strongest intensity,and then low-hung temperature inversion and high-hung temperature inversion follow.Frequency,thickness and intensity of temperature inversion of differ-ent types have a certain seasonal difference.For surface inversion,its frequency and thickness is the largest in spring and there is no significant difference in other seasons.In general,intensity of temperature inversion is the strongest in winter and weakest in summer.Diurnal variation of inversion of three types is obvious,and frequency and thickness of inversion is greater at 08:00 than at 20:00,so is intensity of inversion.Analysis of characteristic of atmospheric boundary layer inversion in Chengdu area is of important significance to understand diffusion of pollutant in this region.关键词
