| 摘 要： | Investigated are effects of the total cloudiness and other factors on earth-atmosphere net radia-tion(EANR)and analyzed is its relation to other components and ground surface net radiation inthe context of ERBE and ISCCP.Evidence suggests that planetary scale albedo and earth-atmo-sphere short wave absorption radiation have maximum effect on the net radiation under study,withthe influence of cloud and latitude displayed predominantly through the two factors;OLR has rela-tively weak effect;the earth-atmosphere net radiation is well correlated with surface net radiation.Analysis is also performed of the geographic distribution of the earth-atmosphere net radiationthroughout China,and the annual curve of the net radiation on a local basis is marked by high(low)value in summer(winter)with the impact of factors.including total cloudiness responsiblelargely for the shift of the months with maximum.

| Abstract: | Investigated are effects of the total cloudiness and other factors on earth-atmosphere net radia- tion(EANR)and analyzed is its relation to other components and ground surface net radiation in the context of ERBE and ISCCP.Evidence suggests that planetary scale albedo and earth-atmo- sphere short wave absorption radiation have maximum effect on the net radiation under study,with the influence of cloud and latitude displayed predominantly through the two factors;OLR has rela- tively weak effect;the earth-atmosphere net radiation is well correlated with surface net radiation. Analysis is also performed of the geographic distribution of the earth-atmosphere net radiation throughout China,and the annual curve of the net radiation on a local basis is marked by high (low)value in summer(winter)with the impact of factors.including total cloudiness responsible largely for the shift of the months with maximum. |
