Aiming at this problem that the 2D display systems of wind profiler radar cannot display 3D wind fields, the 3D visualization method of of wind fields from the wind profiler radar based on WebGL is studied in this paper. The principles and advantages of 3D graphics rendering based on WebGL are introduced, and the 3D modeling and rendering method of wind fields from wind profiler radar are described in detail. On the basis of this method, a 3D visualization system for the wind fields from wind profiler radar based on the B/S mode is developed, and the functional characteristics and advantages of the system are introduced. Compared with the 2D display system, the 3D visualization system presents the spatial distribution of the wind fields in a more intuitive and realistic form, and users can observe the 3D wind fields from any angle of view, which is convenient for meteorologists to analyze wind convergence (divergence) and boundary layer convergence lines, and provides an effective technical means for monitoring and forecasting severe convective weather.
