摘要
采用WRF/CALPUFF耦合模型,对哈尔滨市2013年10月15日~10月24日一次严重雾霾污染天气进行模拟,得到此次雾霾污染PM2.5质量浓度分布特征.模拟结果表明,由于"热岛效应"的存在发生严重污染的区域主要集中于哈尔滨市辖区内,周边区县存在不同程度的污染.气象条件也对本次雾霾现象产生重要影响,10月20日及21日两天,气温偏高(最高18℃,最低5℃)、相对湿度较大(98%)、夜间混合层高度小于100 m,伴随静风天气导致雾霾现象极其严重,空气质量等级为六级,市辖区内PM2.5质量浓度最大值超过1 000μg/m3.
Using the WRF / CALPUFF coupled air quality model simulates a serious haze pollution weather to show distribution of PM2. 5 concentration in Harbin during October 15 to 24,2013. It showed that area occurred serious pollutions was located in municipal districts. It has a different degree of pollution in other counties.Weather conditions have an important influence on the smog pollution. During October 20 to 21,2013,with calm wind,high temperature( highest 18 ℃,lowest 5 ℃),98% relative humidity,the mixing layer height was less than 100 m in the night. A series of bad weather conditions cause this serious smog pollution,with air quality level for level 6. The max concentration of PM2. 5 was over 1 000 μg / m3 in municipal districts.
