Because change of volume reflected eroding process of watershed and surface change reflected change of topography surface, this model described relationship between watershed topograph and erosion.iv As a quantitative index of wateshed topography, topograph fractal demension can represent surface shape information of watershed topography in the round. Reseach find that watershed model and actual watershed show good fractal character. Topography fractal dimension related with process of development of watershed physiognomy and represented degree of watershed development, v Sediment yield intensity of watershed model reflected erosion characteristic of watershed model in different development phase.

流域模型产沙强度的变化反映了流域模型在不同发育阶段的侵蚀特征，模拟试验研究结果表明：在整个流域模型地貌地貌的发育过程中，其产沙强度呈现由小到大，然后又逐渐减小的总体趋势，流域模型单位降雨产沙率及平均输沙率与地形分维数表现为Gaussian模型关系，其关系形式与结论3中相对体积和表面积之间关系相似，进一步说明了以地形分维数表达地形变化的合理性。

It is found that the GRAPES model is able to reproduce the observed atmospheric kinetic energy spectrum, including the transition to k-5/3 dependence in the small-meso scale. Meanwhile, there exists a maximum effective time-step, when the time-step is smaller/larger than the maximum effective time-step, the simulated kinetic energy spectrum gradually decays/unphysically grows as the time-step increases.

文中使用基于半隐式半拉格朗日动力框架的全球/区域一体化模式GRAPES进行数值模拟试验，然后计算GRAPES模式的动能谱并与实际观测得到的大气动能谱比较，得到GRAPES模式能够很好地复制出实际大气动能谱的分布特征，包括从大尺度区域的E∝k-3关系向中尺度的E∝k-5/3关系的过渡特征。
