China has made significant strides in its meteorological observation capabilities, establishing a comprehensive system that integrates land, sea, air, and space-based technologies. According to the China Meteorological Administration (CMA), these advancements are set to revolutionize weather forecasting and disaster prevention both domestically and globally.
Fang Xiang, Director General of the Department of Integrated Observation at CMA, highlighted at a recent press briefing in Beijing that the country now boasts the world's largest weather radar monitoring network. This impressive network comprises 546 weather radars, whose coverage has expanded dramatically over the past five years, ensuring more accurate and timely weather data.
In addition to ground-based systems, China has deployed nine Fengyun meteorological satellites for high and low orbit observation. Fang emphasized that China is the only nation with satellites capable of dawn, morning, afternoon, and precipitation measurements, providing critical data to 132 countries and regions and serving over 160,000 users worldwide.
The meteorological observation system also features over 76,000 ground-based automatic observation stations, guaranteeing full coverage of all townships across the Chinese mainland. Complementing this are 27 national climate observatories and eight national atmospheric background stations, which ensure comprehensive monitoring of key climate areas.
Addressing environmental concerns, the system includes a national greenhouse gas observation network with 120 high-precision stations. The data collected is regularly published, contributing to global efforts in climate change research and mitigation.
Space weather observation has also been ramped up, with 61 national space weather observation stations established to support monitoring and early warning services. Bi Baogui, Vice Administrator of CMA, reported significant breakthroughs in key technologies, including the innovative \"hundred-meter level, minute-level\" forecasting technology. This advancement has proven crucial in disaster prevention and mitigation efforts.
Artificial intelligence has been seamlessly integrated into the meteorological applications, enhancing predictive accuracy and operational efficiency. Bi highlighted the release of three independently developed meteorological large models: \"Fengqing,\" \"Fenglei,\" and \"Fengshun.\" These models leverage advanced AI to provide more precise weather forecasts and climate predictions.
Furthermore, the BeiDou sounding system and three-stage sounding technology have been pivotal in developing high-quality meteorological sounding solutions. These technologies offer a Chinese approach to global meteorological advancements, reinforcing China's position as a leader in weather observation and forecasting.
With these comprehensive improvements, China's meteorological observation system is not only enhancing its own weather forecasting capabilities but also contributing valuable data and technologies to the global community, fostering better preparedness and resilience against weather-related challenges.
