随着台风预报技术的发展，结合WebGIS的应用也日趋增多。但由于受到HTML等技术的限制，许多工作都必须在服务器端执行，增加了服务器的压力，并延长了系统响应时间。因此，Flex作为富客户端开发的代表技术框架，为新型WebGIS的设计和开发提供了强有力的技术支撑。通过研究Flex技术以及ArcGIS API for Flex接口包，利用Web Service和XML技术实现台风预报系统的前后台数据通信，基于Flex开发了一套可用于台风预报分析的系统。该系统共包括四个模块，分别是地图模块、预报员预报模块、预报会商模块和工具模块。该系统运行结果表明，基于Flex技术的台风预报系统较其他系统具有如下优势：①可在客户端执行部分系统功能，减轻服务器端的压力，提高系统响应速度；②用户界面得到美化，提高系统的交互体验；③利用该系统，台风预报员可以加载已有的台风预报数据进行分析，并在此基础上，进行各自的预报及会商预报。%With the development of typhoon prediction technology , application with WebGIS is more and more popular .Because of the limitation of HTML, many jobs need to be done on the server side which will further increase stress on the servers and extend the net -work's response time.Flex, as one of the best internet application technologies , supports the design and development of WebGIS . Through in-depth study of the Flex technology and ArcGIS API for Flex , we propose a typhoon prediction analysis system with Web Service and XML for data interoperation.In this system, there are four modules, including map modules, prediction modules, consul-tation modules and tool modules .After system operation test , it shows that WebGIS system with Flex has the following four advantages that jobs can be done on the client side to relieve stress on servers and improve response speed , landscaping user interface and users ’ experience can be enhanced , forecaster is able to add existing data to do analysis by using this system , and on that basis , prediction and consultancy prediction can be done upon the analysis .
