分析表明，预报系统不仅能定性预报沙尘天气的空间分布与时间演变，而且能定量预报沙尘源地、大气中的沙尘浓度、沙尘的输送以及沉降。Air（初三适用）

Analysis shows that the system not only can quantitatively predicate the spatial distribution and temporal change of the dust , but also the source , density in the air , transfer and deposition .

本文在GIS技术的支持下，对热带气旋源地空间分布模式和热带气旋路径的空间相似两个问题做了探索性研究，这两个问题对热带气旋的预报均具有很高的参考价值。

With the support of GIS , the thesis has a discovering research on two problems , Tropical Cyclone source spatial distribution pattern and Tropical Cyclone path similarity , which are most valuable for the forecast of Tropical Cyclone .
