基于GIS技术相似台风检索系统的设计

该文应用GIS技术建立了一种利用历史数据进行台风路径预测的模型.该模型应用关键点相似度法,利用地理信息系统（GIS）的空间分析功能,建立当前查询台风中心位置的缓冲区和按照各种要求选取的关键点,从历史台风数据库中搜索路径相似的台风,建立主要影响台风的天气要素库（包括850HPA、700HPA、500HPA的温、压、湿、风等信息）和可降水含量、水汽通量、螺旋度、湿位涡等有关物理量场的显示系统,并且建立1h间隔的主要影响台风风雨影响数据库的查询系统.

Design of technology similar to typhoon retrieval system based on GIS

This application of GIS technology to establish a historical data for forecasting typhoon model. Application of the key points of the model similarity method, the use of geographic information system （GIS） spatial analysis function, The typhoon center to establish the current query buffer and in accordance with the various requirements of the selected key points, from a historical database search track similar to the typhoon, Establishment of the main library of the typhoon weather elements （including 850HPA, 700HPA, 500HPA the temperature, pressure, humidity, wind and other information） and the content can be precipitation, water vapor flux, helicity, MPV and other relevant physical field of display systems, and lh intervals to establish the main effects of the typhoon wind and rain database query system.
