| 摘 要： | 对闸北区空气自动监测站2009年SO2、NO2、PM10的浓度和气象参数变化特征进行研究,可吸入颗粒物的时间变化特征表明,总体上呈现冬春季高、夏秋季低;PM10与降水量、相对湿度、温度呈现一定的负相关性,但与风速的相关性随季节不同而不同,与气压略呈正相关性。对典型日和灰霾日PM10、SO2、NO2以及相应气象因子的特征进行了分析比较。

| Abstract: | The whole year SO2, NO2, PMl0 concentration and meteorological parameters from Zhabei District Automatic At- mosphere Monitoring Station in 2009 were summarized and analyzed. The temporal variation of PM,o indicated that the mass con- eentration was higher in winter and spring and lower in summer and fall. PMI0 mass negatively correlated to precipitation, relative humidity, temperature. But the correlation of PMt0 mass to wind speed varied seasonally and the positive correlation of PMIo mass to atmospheric pressure was observed. The characteristics of SO2, NO2, PMlo and meteorological factors in typical and hazy days were summarized and compared. |
