Based on OPENGL and the related 3D computer imaging algorithms, a 3D visualization platform system of radar networking data is developed. As examples, the radar data from typhoons Ramasun and Kalmaegi and Wind Profiler radar data are introduced into this 3D visualization platform display system. The results show that the platform system can not only display fully intuitive construction of 3D structure of the typhoon, but also show the internal structure according to the demand. The combination of Doppler weather radar and wind Profiler radar improve the monitoring capability of atmospheric winds. It is a good complementation of SWAN and also an advance in operational applications of 3D radar networking products.
