摘要
我国是世界上受热带气旋影响最为严重的国家之一,因此研究其机理演变规律将更有利于指导做好防灾减灾工作。本文利用GIS的显示功能,重建和再现热带气旋的登陆路径全过程,在空间格局上,进行时间维的动态演化模拟,为更好地研究热带气旋的演化机理提供一种实用的分析手段。结果表明,该方法对在时空上了解和认识气旋登陆演化全过程的研究具有一定意义。
China is one of the countries seriously affected by the tropical cyclone. It is important for us to master the rules of tropical cyclone evolution that will guide us to work in hazard prevention and reduction. This paper made full using of the function of 3D-GIS to rebuiht the progress of tropical cyclone landing route and analyze the spatio-temporal dynamical evolution. It provided one appropriate method to study the mechanism of tropical cyclone. The results indicated that the method is benefit for us to learn and recognize the spatio-temporal mechanism of tropical cyclone.
