上海市空气质量与气象条件关系分析
he analysis of the relationship between air quality and meteorological condition in Shanghai
对上海市2001-2011年的可吸入颗粒物(PM10)、二氧化硫(SO2)和二氧化氮(NO2)的实测数据和气象资料进行了归纳分析和研究，得出了上海市三种污染物年际和月变化特征，并对这种变化规律进行了详细分析，同时分析了降水、风向和风速对污染物变化的影响，研究表明近几年上海市空气质量得到了改善，空气污染主要出现在冬春季，夏秋季空气质量相对较好。降水和大风能有效降低污染物浓度，降雪比降雨对污染物的清除能力更大，其中中雪的清除能力最强，偏东风更有利于降低污染物浓度。
he measured data of PM10, SO2, NO2 and meteorological data of Shanghai from 2001 to 2011 were summarized and analyzed. The annual and monthly changing characteristics of the three pollutants in Shanghai were addressed at the same time. The influence of precipitation, wind direction and wind speed on the PM10, SO2, and NO2 were discussed. The results showed that the air quality of Shanghai City have been improved in recent years, air pollution occurred mainly in the winter and spring, relatively, air quality is more better in summer and autumn. The concentration of PM10, SO2, and NO2 were strongly affected by precipitation and wind, the removal capacity of snowfall on PM10, SO2, and NO2 was better than rainfall, and the moderate snow removal ability is the strongest, the concentration of PM10, SO2, and NO2 will decrease in the the east wind conditions.
