The threedimensional structure and change of a typhoon in the landing period have close relationship with the its path and intensity. Using the CINRAD 3D mosaic typhoon products to analyze in realtime the threedimensional structure of the typhoon is important to typhoon nowcasting and warning. According to the actual situation of typhoon monitoring and warning, a CINRAD 3D mosaic product display system for typhoon is developed, on the basis of the CINRAD 3D mosaic product production system for typhoon. Taking into account the demand of realtime processing and postanalysis, the realtime monitoring, the animated display of the typhoon and CINRAD 3D mosaic products, the superposition of wind and other functions are realized. Using the section interpolation algorithm and the identification algorithm of nonsymmetric direction of typhoons, the automatic positioning and display section of the largest symmetry axis, nonsymmetric axis and the average RHI section at different distances of the typhoon are achieved. The display method, the related algorithms, and the main functional modules of the system are described. By using Typhoon HAGUPIT as an example, analyzed are the asymmetry and movement of the typhoon path and the correspondence between the strong echo areas and spiral rainbands with the images of Typhoon HAGUPIT. The application indicates that the product display system achieved satisfactory results.
