In the dawn of the mobile computing era, it has witnessed an exciting leap in information technologies such as artificial intelligence, big data mining, and GPU parallel computing, as well as the unification of Web standards. This progress facilitates the birth and development of a great number of meteorological data visualization applications targeting mobile computing platforms. However, thanks to underpowered computational capability and incomplete features of the graphics toolkit in mobile devices, most domestic Web applications lack innovative visualization methods, and have poor browser compatibility and performance. To deal with these problems, a B/S meteorological data interactive analysis and display Web application named WeatherApp has been developed. Two innovations are proposed. First, a unified two- and three-dimensional digital Earth engine is constructed. It not only provides commonly-used geographical information system features but also is capable of quick switching between views of different dimensions. Next, a number of advanced three-dimensional visualization methods, including vector field flowlines and volume rendering, are developed. The proposed application has been applied in typhoon forecast operations, and encouraging results are obtained. By supporting all mainstream Web browsers built for both desktop and mobile platforms, WeatherApp provides a convenient way for users to view data of interest anywhere and anytime, greatly enhancing users’ productivity.
