Core Viewpoint - The article discusses the implementation of a "progressive meteorological service" in response to severe weather events in southern China, aimed at enhancing flood prevention and emergency response efforts [1][2]. Group 1: Progressive Meteorological Service - The "progressive meteorological service" involves providing increasingly precise and timely weather forecasts and warnings, tailored to specific regions and levels of government, to support flood prevention decisions [2][4]. - The service is structured into three levels: trend alerts, disaster warnings, and emergency notifications, with five components including climate trend forecasts and disaster weather warnings [4][5]. Group 2: Case Studies and Implementation - In Guizhou, the "24631" service model was employed during a flood crisis, allowing for detailed weather forecasts and timely government responses, which facilitated effective evacuation and resource allocation [2][3]. - In Yunnan, the "1262" model was used to predict heavy rainfall, leading to the successful evacuation of 3,904 individuals without any casualties [4]. Group 3: Communication and Coordination - Meteorological departments proactively communicate with local governments, providing timely alerts to relevant officials to enhance disaster preparedness [6][7]. - The integration of meteorological services into local governance structures has improved the speed and effectiveness of emergency responses to weather-related disasters [7].
