| 摘 要： | 根据近年开展污染气象观测整理计算的33个项目54期有关边界层小球测风和低探观测资料,分析了陕西省冬季和夏季接地逆温强度及厚度区域分布特征,不同区域接地逆温最大厚度出现时风速廓线和温度廓线特征。分析表明:陕西省接地逆温以西安、咸阳和宝鸡等大城市周围,工业区以及陕北长城沿线荒漠区最为强盛,太白山区及秦巴山区最弱,山区、丘陵地带弱于平原地区,冬季强于夏季;接地逆温最大厚度出现时,地面风速较小,大气层接稳定,陕北长城沿线荒漠区大气水平扩散能力较强,陕南山区次之,关中城市工业区最弱。

| Abstract: | According to meteorological pollution observations in recent years,it was analysed the characteristic distribution of intensity and depth of the surface inversion in seasons of winter and summer in Shaanxi Province,calculating data from lower atmosphere sounding and pilot balloon from 33 projects.The results show that the surface inversion is the strongest in the surroundings of Xi'an,Xianyang and Baoji Cities,the industrial area and northern desert along the Great Wall,but is the weakest in Qinling and Dab... |
