Analysis on Characteristics of Aerosol Particles Distribution in Cloudy Day in Hebei
2010
Based on the atmospheric detection data of two flights in middle and southern parts of Hebei in the spring of 2007,the characteristics of aerosol particles concentration and spectral distribution in cloudy day were analyzed.The results indicate that,under the weather systems of southern trough and north vortex,the overall trend of aerosol particle concentration decreases while height is increasing;however,it increases with height when there are cirrostratuses in upper air.And there is a clear accumulation of aerosol and cloud droplets in the inversion base.Affected by the complex weather systems,the aerosol particle spectrum shows a multiple peak distribution due to the disturbance of updraft or turbulence.
