In this paper,the research and implementation of MeteoExplorer Touch software,a scientific data visualization system designed especially for mobile computing devices that use touch gestures to manipulate,is introduced.This software system is also the world's first Windows store application that offers touch manipulation experience.The system enjoys the following technical advantages.First of all,by making use of the innovative technologies introduced in Windows 8 and Windows RT operating system,MeteoExplorer Touch manages to provide a number of exciting features.To name a few,it allows users to zoom and pan the base map using slide,pinch,and stretch gestures.It is able to restore the last session after the operating system recovers from the standby state.Next,MeteoExplorer Touch is not merely a picture viewer.Instead,it provides a large proportion of the functionalities offered by the professional meteorological applications designed for desktop and workstations.These functionalities include data analysis,objective analysis,physics computation,graphics product generation,geographic information,and layer management.Third,MeteoExplorer Touch concentrates on performance and user experience.To accomplish the goal,C++programming language is used for implementing functionalities,XAML markup language is used to design user interface,and DirectX 11 hardware accelerating rendering technology is used for graphics display.All the proposed software system shares the same strengths as those provided by a typical native application in that it offers high performance,while at the same time does not require much system resources.
