成功发射！风云四号C星有哪些“超强能力”

Core Viewpoint - The successful launch of the Fengyun-4C satellite enhances China's capabilities in monitoring extreme weather and addressing climate change, marking a significant advancement in meteorological satellite technology [1][3]. Group 1: Observational Performance - The Fengyun-4C satellite features six advanced payloads that significantly improve the frequency and precision of monitoring small to medium-scale weather systems [2]. - The satellite's geostationary radiation imaging instrument has doubled its spatial resolution, allowing for full-disk observations every 5 minutes and regional imaging every minute [2]. - The interferometric atmospheric vertical profiler has improved its spatial resolution from 12 kilometers to 8 kilometers, enabling more accurate data for numerical weather prediction and typhoon modeling [2]. Group 2: Enhanced Early Warning Capabilities - The Fengyun-4C satellite provides enhanced monitoring and early warning for severe weather events, with a 33% improvement in time resolution for monitoring strong convective clouds compared to its predecessor [6]. - In the case of severe convective weather, the satellite can predict hail and heavy rainfall areas 1 to 2 hours in advance, improving warning accuracy by approximately 20% [6]. - For typhoon monitoring, the satellite captures rapid changes in temperature and humidity in the typhoon's core, significantly reducing forecast errors for path and intensity [6]. Group 3: Climate Change Response - The satellite's capabilities in atmospheric composition detection will enhance numerical forecasting and improve responses to climate change [7]. - It can continuously observe key atmospheric parameters, significantly reducing precipitation forecast errors and providing precise monitoring of extreme heat events [7]. - The satellite's high-frequency monitoring of vegetation indices and surface temperatures aids in identifying drought conditions and their development [7]. Group 4: Future Developments - Following the launch of Fengyun-4C, China plans to continue launching additional Fengyun satellites, including optical series and the world's first geostationary microwave detection satellite [10]. - The Fengyun-4C will work in conjunction with existing satellites to enhance global and regional disaster prevention capabilities [10]. - China has successfully launched 23 meteorological satellites across two generations, providing data services to 133 countries and regions, supporting disaster prevention and scientific research [10].
