热带气旋卫星遥感客观定位方法研究进展

Progress in objective position methods of tropical cyclone center using satellite remote sensing

首次从云系形态识别、风场结构分析、云体温湿反演、时空运动匹配等4个崭新角度梳理归纳了热带气旋卫星遥感客观定位方法研究进展,分别介绍此4类方法的实现原理与过程,比较分析各种方法的优缺点与适用性。总结认为,上述方法虽大多仍处于探索研究阶段,但其优于传统人工目视判读定位法的诸多特点将使之成为发展应用的必然;同时综合比较指出,结合运动特征的混合智能算法将是热带气旋中心定位的未来方向;此外建立集成多种资料和算法的热带气旋综合客观定位系统,也有利于提高热带气旋中心定位的稳健性和准确率。

This paper summarizes the progress in objective position methods of tropical cyclone center based on satellite remote sensing from four new perspectives.They are cloud pattern recognition,wind field analysis,temperature/humidity structure inversion,and tempo-spatial movement matching.The four methods’ principles and realization processes are introduced,as well as their advantages,disadvantages and applicability.Finally,this paper concludes that although most of the above methods are still at exploratory research phase,their many features are better than the traditional positioning method of artificial visual interpretation,which will make them inevitable in locating tropical cyclone center.Comprehensive comparison also points out that one hybrid intelligent algorithm combined with motion characteristics will be the research and development tendency of tropical cyclone center location technology in future.Besides,it is necessary to establish an integrated tropical cyclone center positioning system that synthesizes various data and algorithms,which will be conducive to improve the stability and accuracy of tropical cyclone center positioning.
