| 摘 要： | 1982年夏季,我国第一架装有PMS粒子测量系统的气象科研考察飞机在西安市首次进行大气物理科学考察。本文仅对6月8日西安城市晴天大气气溶胶粒子观测。资料进行了初步分析。结果表明:西安市晴天气溶胶粒子(直径0.5-8μm)浓度值范围在4×10~0-3.8×10~1个/cm~3,分布趋势随高度递减,逆温层对粒子垂直输送有阻滞作用。同时对气溶胶粒子谱分布及谱分布函数作了探讨,并对一些参数进行理论计算。

A case analysis of aerosol particles observation under fine weather over Xian |
| |
| Abstract: | In the summer of 1982,the first atmospheric science investigation had been performed in Xian, using an aircraft installed with PMS instruments. The case analysis of aerosol particles observation under fine weather condition is presented in this paper based on the data of 8. June The results show that the concentration of aerosol particles (0.5-8°m diameter) ranges from 4×100-3.8×101/cm3, decreases with inereasing height.The temperature inversion layer has obstructive effect on the vertical transportation of aerosol particles. The particle size distribution expression and its parameters are given. |
