| Abstract: | By using of the observed data at desert station of HFIFE in 1991,the characteristics of the atmospheric turbidity and the effect of the dust atmosphere on the surface radiative energy budget over desert region of Heihe River basin in spring were analysed In spring (March May),the mean atmospheric turbidity is high affected by the dust storm Most of the dust caused by the dust storm are held in the atmosphere for a long time About one week after dust storm the atmospheric turbidity return to normal The size distribution of the atmospheric dust is identical with Junge distribution The optical depth of the atmospheric dust is high and has good relationship with the atmospheric turbidity coefficient In case of very turbid condition the global radiation decreases,the incoming IR radiation decerases, the outgoing IR radiation decerases in the daytime and increases in the night,for the surface radiative energy budget, the net gain of the radiative energy on the ground surface decreases in the daytime, and the net lose of it decreases in the night |
