| 摘 要： | 利用2000年1月25日～2月3日北京地区冬季二氧化硫体积分数的梯度监测资料,结合北京325m气象塔的同期气象资料,分析了观测期间北京地区二氧化硫的体积分数变化趋势及垂直分布情况,讨论了大气二氧化硫体积分数变化和气象条件的关系及二氧化硫的来源问题.研究表明:二氧化硫的体积分数变化及垂直输送与风速、风向、大气稳定度密切相关.风速越小,大气越稳定,近地层大气的二氧化硫污染就越严重;当北京冬季吹SSW、SW、WSW和W风时有较高的二氧化硫.

| Abstract: | Based on the data of the gradient observation of SO2 concentration in winter in Beijing from January 25, 2000 to February 3, 2000, and the meteorological data observed on the meteorological tower in Beijing at the same time, SO2 concentration variations and the vertical variations during the observation were analyzed. The relationship of SO2 concentration variation and meteorological conditions were discussed. The sources of SO2 have been investigated. The results indicate that there is a close relationship between the variation of SO2 concentration and vertical conveyance and wind speed, wind direction and atmospheric stability. The smaller the wind speed and the atmosphere stability are, the more serious the air pollution of SO2 is in surface layer. The higher SO2 concentration were from SSW, SW, WSW and W direction. |
