topographical distribution

Results suggest that ( 1) the topographical factors have robust effect on the spatial distribution of DSR, particularly in winter and autumn when the sun elevation angle is lower;

结果表明：局地地形对太阳直接辐射空间分布的影响非常强烈，尤其是在太阳高度角较低的冬季和秋季；

In addition, under a more general source distribution function and an arbitrary boundary condition, we obtain the numerical solutions of the non-homogeneous Weber equation for different topographical slopes, so as to study the relationship between the topographical slope and the mean wind field under these conditions.

还对非齐次weber方程在较一般的源函数分布和边界条件下，对不同地形坡度求了数值解，以便研究这种情况下地形坡度和平均风场的关系。
