| 摘 要： | 通过北京市2013年的PM2.5/PM10资料与GPS可降水量资料比较发现,在秋冬春季节,PM2.5/PM10与GPS可降水量呈明显的正相关性,相关系数大于0.5,在个别时段达到了0.89,而这一相关性在降水较多的夏季并不明显;水汽含量的上升是秋冬春季节雾霾天气过程发生的重要因素。

| Abstract: | This reseach compares the correlation between GPS PWV (precipitable water vapor) and PM2.5/PM10 of Beijing in 2013. It is concluded that there is a significantly positive correlation among autumn, winter and spring seasons, in which the correlation coefficient is greater than 0.5 and the best correlation coefficient amouted to 0.89. The correlation is not obvious in summer. The important factor in causing fog and haze weather is the rise of PWV in the autumn, winter and spring seasons. |
