The results show that the asymmetric distribution of orography and that of horizontal diffusion coefficients are likely to be the causes leading to the asymmetric motion.
结果表明：非对称的地形分布和水平扩散系数的分布可能是导致非对称运动的原因。

The results from a sensitivity experiment with decreased orography height show that the upward and southward transport of dust aerosols is depressed when orography height is decreased.
敏感性数值试验结果表明，降低高原地形会使得高原上空沙尘气溶胶粒子向南和向上的传输变弱。
