摘要
本文利用临泽、化音、平川和沙漠4站1990年夏末(8月)太阳辐射平衡观测资料,分析了各站太阳辐射与长波辐射各分量的变化特征。结果表明:该地区太阳辐射很强,4站太阳总辐射的日变化规律均是随太阳高度角的增大或减少而相应的增大或减小;地表反射率除平川站外,其它3站的日变化规律均呈U型;化音站相对于其它各站有效辐射量值最大;对于地面净辐射来说绿洲的值最大。
In this paper, the variation properties for the components of surface solar radiation are analysed by using the short-period observational data of radiation balance at Linze ( Oasis), Huayin(Gobi), Pingchuan (where Oasis and Desert intersect) and Desert stations in August 1990. The results show that the global radiation in these regions is very strong. At each of the four stations, the daily variation of global radiation shows corresponding variation along with the increasing or decreasing of the solar zenith angle. Ex-
cept at Pingchuan station, the daily mean variations of surface albedo at the other stations are 'U' types. When the daily mean totals of effective radiation are compared, we see that the value at Huayin is the largest one. The daily mean total of net radiation at Linze is the largest one.
