Design of a severe weather monitoring and warning system for Doppler weather radar PUP products

Until now, Doppler radar PUP product display programs simply display images and information and ignore storm analysis applications. Through the data format study of PUP products, a strong convective weather monitoring and early warning system for Doppler weather radar PUP products is developed by using DELPHI XE2 programming language. All source codes of the system are fully self-written to complete reading and analysis of PUP products, which can read, analyze, and display Doppler weather radar 19 (36 files) PUP products individually or in batches, to identify and locate severe storms, and store image and features information of the storm, conducive to expanding the breadth and depth of comprehensive application of PUP products. This system and PUP products can not only obtain hail occurrence probability information and issue hail warnings in real time, but also can further study the development mechanism of severe storm weather. At present, the system and its products have been applied in relevant business units of Yunnan Meteorological Bureau to meet the needs of strong convective weather monitoring and early warning services, artificial hail suppression operation command and scientific research. The WINDOWS API function and the MIF format administrative boundary are used in the system to more accurately accomplish township positioning of strong weather. The program complexity, the code amount and the system volume are all small, which can provide reference for WINDOWS program design with single positioning function.
