Analysis of meteorological elements and air pollution during a sand dust weather process in 2010 in Liaoning province
摘要
Abstract
Based on the meteorological observational data from weather stations and monitoring data from environment protection department,the upper and lower weather situation and the main meteorological elements during a sand dust weather event occurred on April 8,2010 in Liaoning province were discussed.The results indicate that this process is influenced by cold air moving to the east in Lake Baike region and Mongolia low pressure.The strong Mongolia cyclone makes strong allobaric gradient and wind speed on ground,which are the dynamic reasons forming sand dust weather.Many meteorological elements such as wind,visibility and humidity change sharply when sand dust weather occurs.PM10 concentration increases quickly in a short time because of the influence of sand dust weather,while the concentrations of black carbon,SO2 and NO2 decline in some extent because of favorable diffusion conditions such as gale in Shenyang.关键词
