摘要
依据2013年北京天坛站地面PM_（2.5）/PM_（10）、BJNM站GPS水汽和无线电探空水汽观测资料,分别进行了PM_（2.5）/PM_（10）与GPS水汽、无线电探空整层（分层）水汽的比较。研究发现,夏季GPS水汽（PWV）变化与PM_（2.5）/PM_（10）变化没有明显的相关性规律;在秋、冬、春季节,GPS PWV变化与PM_（2.5）/PM_（10）变化的相关系数大于0.5;秋、冬、春季节无线电探空整层（分层）水汽变化与PM_（2.5）/PM_（10）变化的相关系数大于0.5,第3、4层（850~3 000m）水汽变化与PM_（2.5）/PM_（10）变化的相关性最佳。
Based on the observation data of ground PM_（2.5）/PM_（10）,GPS Precipitable Water Vapor（PWV）and Radiosonde PWV in Beijing in 2013,the change among PM_（2.5）/PM_（10）,GPS PWV and Radiosonde PWV per layer of PWV was compared.We found that there is significantly positive correlation between ground PM_（2.5）/PM_（10） variation and ground GPS PWV change during autumn,winter,and spring.Such a correlation does not exist in the rainy summer months.According to the comparisons between ground PM_（2.5）/PM_（10） observations and aerial PWV Radiosonde observations made in autumn,winter,and spring,the correlation between ground PM_（2.5）/PM_（10） variation and total aerial PWV change is also significantly positively related.The correlation between PM_（2.5）/PM_（10） variation and the 3th/4th water vapor layer（850-3 000m）PWV change is the most significantly positively related value.
