【摘要】 在讨论实测总辐射与地表净辐射月平均通量密度相关性的基础上,分析了两者气候计算值间的相关性问题,并初步证实两者的一致性。绘制出利用回归方程推算的地表净辐射年平均通量密度全国分布图,与利用地表辐射平衡方程余项所得结果比较一致。还讨论了坡地总辐射与净辐射气候计算值间的相关特点,指出当坡度小于20°时,坡地总辐射与净辐射的回归方程系数与水平地面的一致。随着坡度增加,回归方程系数发生相应变化。更多还原

【Abstract】 on the basis of the correlation between global radiation measurements and monthly means of surface net radiation flux densities (SNRFD), analysis is done of the correlation of their climatological calculations, confirming roughly their consistency, with a prepared nation-wide chart of annual mean SNRFD with the aid of the regression formula. The pattern agrees fairly well with the results by the residual term of the surface radiation balance expression. Besides, the correlation characteristics are examined between the climatological values of global and the net radiations for slope land, indicating that for the slope〈20° their coefficients of the regression equation are in concord with those for a horizontal ground and with the increasing slope the coefficient changes correspondingly.更多还原
