气象条件对青岛地区气溶胶光学特性的影响

The Effect of Weather Situation on the Aerosol Optical Properties in Qingdao

利用 2 0 0 2年 4月至 2 0 0 3年 10月多波段太阳光度计资料和同期的气象观测资料 ,分析了不同气象条件下青岛气溶胶光学特性的变化。气象条件的转变与青岛地区气溶胶光学特性之间具有很好的响应关系 :南风盛行时会加大光学厚度 ,并增强气溶胶对 >5 0 0nm波段太阳辐射的散射能力 ;轻雾和霾在青岛气溶胶光学厚度中占有较大比重 ,而霾对 <5 0 0nm波段辐射的散射能力较强。

Based on the multi-wavelength sky radiometer data and the weather data obtained on the ground from April 2002 to October 2003, the aerosol optical properties under different weather situations are analysed in this paper. The aerosol optical depth (AOD) and aerosol scattering of solar radiation in wavebands greater than 500nm increase when the south wind prevails. Light fog and haze have a larger contribution to the AOD, and haze is stronger in scattering radiation in wavebands shorter than 500nm.
