| Abstract: | In this paper,the climatic characteristics of solar ultraviolet radiation over oasis region in HEIFE are analyed on the basis of the solar UV radiation data observed over Zhangye and Linze stations in HEIFE from Oct.1990 to Oct.1992.The results are as following:(1) The annual mean daily total of UV over oasis region in HEIFE is abour 0 48 MJ/m 2,less than that over Qinghai-Xizang Plateau region and about half of that over Lhasa rehion.(2)The ratio of the UV to global radiation is littler than other tegion,the annual mean value is about 3%,there is two step change in annual variation caused by vapor and aerosol.(3)The reationship between the UV and global radiation in daily total is better than that in instantaneous value.(4)There is aregular variation of the tatio of the instantaneous UV to global radiation when global radiaion is strong,but the variation trend are different in summer and winter when global radiation is weak.(5)The ratio of the UV to global radiation is a quadratic function of daily total of global radiation |
