Outdoor sports events, opening ceremonies, concerts, and other activities are greatly constrained by weather conditions and require high accuracy and timeliness of meteorological forecast and warning information. Therefore, meteorological service guarantee becomes an essential component of the organisation, implementation, and operation system of major events such as the Olympic games and the Asian games. This article introduces the construction overview of the comprehensive command platform for meteorological support services for the 19th Asian games in Hangzhou and elaborates in detail on the platform’s system architecture, key technologies, main functions, and application situation. The platform adopts the SpringCloud microservice architecture design and utilises development technologies such as component-based development and RPA system integration to achieve rapid customised development and rolling iteration. Based on the Tianqing big data cloud platform of the China Meteorological Administration, it realises the aggregation and fusion of various Asian games meteorological data applications, successfully completing the meteorological support services for Asian games events and providing reference for meteorological departments to build relevant major event meteorological command and support systems.
