河北地区秋季气溶胶飞机探测资料分析
An observational study of the aerosol distributions over Hebei area during autumn
摘要
Abstract
Using PMS data obtained in Hebei province during the autumn from 2005 to 2007, combined with weather data, the aerosol particles were analyzed in different weathers and height as well as cities. The results show that the average diameter of fine particles was 0. 180 μm in 2006-2007, it was 0. 05μm bigger than the size in 2005. The high number concentration near surface always occurred under the conditions of weak wind speeds, low humidity, presence of inversion or mist and haze. The number of aerosol concentration was connected with the ground atmospheric conditions and the rainfall amount in artificial rainfall, and the removal of aerosol particles was obvious. The aerosol distribution in precipitation weather followed bimodal distribution; in sunny and cloudy weather, the size distribution followed uni-modal distribution. The aerosol pollution was very heavy in Handan and Shijiazhuang. Over the sea ( Ca-ofeidian) , the aerosol particles concentration was lower than on land over an order of magnitude.关键词
