依据北京2013年PM2.5/PM10、GPS水汽和无线电探空风速资料,发现水汽变化与PM2.5/PM10变化呈正相关,风速变化与PM2.5/PM10变化呈负相关。在风速较小情况下,水汽变化与PM2.5/PM10变化呈显著正相关,水汽上升对应了GPS水汽变化与PM2.5/PM10质量浓度的上升,水汽下降则对应了PM2.5/PM10质量浓度的下降。分析了水汽与PM2.5/PM10变化显著正相关的原因。%Based on the observation data of PM2.5/PM1 0 ,GPS PWV (Precipitable Water Vapor)and Radio-sonde wind speed in Beijing in 201 3 ,it is found that there is positive correlation between PM2.5/PM1 0 variation and GPS PWV change;while negative correlation between PM2.5/PM10 variation and Radiosonde wind speed change. During the period of less wind speed,the PWV changes are significantly positive correlated to PM2.5/PM1 0 varia-tion.The rising of PWV is corresponding to the rising of PM2.5/PM10 variation;while the decreasing of PWV is cor-responding to the decreasing of PM2.5/PM1 0 variation.It is analyzed the cause of significantly positive correlation between PM2.5/PM10 variation and PWV change.
