呼和浩特市大气污染物浓度与气象要素的灰色关联分析
Grey Relevant Analysis between Atmospheric Density of Pollutants and Meteorological Elements in Hohhot
【摘要】 基于呼和浩特市大气污染和同期气象要素的监测数据,采用灰色关联度方法,研究了气象要素对PM10、SO2、NO2污染物浓度时空变化的影响.结果表明,对PM10影响最强的气象要素是日平均风速,而对SO2和NO2影响最强的气象要素是日平均相对湿度,逆温强度对三者的影响次之,总云量对其影响最弱.研究结果可为呼和浩特市大气污染预报提供有效依据.
【Abstract】 Based on the monitoring data of air pollution and the meteorological elements during the same period of Hohhot,by using the grey relevant method,the impacts of meteorological elements on density changes in time and space of PM10,SO2,NO2 are analyzed by using the grey relevant method.The results show that the daily mean wind speed is strongest for the meteorological elements impact on PM10,and the mean relative humidity for SO2,NO2,the strength of the temperature inversion is followed for PM10,SO2,NO2,and the total cloud cover is the weakest.The results provide an effective basis for air pollution forecast in Hohhot.
【Key words】 air pollutants; density; grey relevant method; grey relevant degree; meteorological element;
