我国已建成陆海空天一体化综合气象观测系统

Core Viewpoint - The Chinese meteorological sector is focusing on high-quality development during the "14th Five-Year Plan" period, emphasizing technological innovation and self-reliance in meteorological services, with significant advancements in forecasting capabilities and disaster response mechanisms [1][2][4]. Group 1: Technological Advancements - The meteorological sector has established a comprehensive observation system consisting of 9 Fengyun satellites, 842 weather radars, and over 90,000 ground observation stations, achieving an 83% monitoring rate for hazardous weather [1]. - The numerical forecasting model has become self-controllable, with the forecast accuracy for the Northern Hemisphere increasing from 7.9 days to 8.1 days, nearing international advanced levels [4]. - The integration of cutting-edge technologies such as artificial intelligence, big data, and quantum technology into meteorological applications is ongoing, enhancing the precision and effectiveness of weather forecasts [1][5]. Group 2: Disaster Response Mechanisms - The meteorological department has developed a rapid response mechanism for weather warnings, allowing alerts to reach emergency responders within one minute, thereby supporting disaster prevention and mitigation efforts [2]. - A progressive meteorological service model has been established, refining forecast timelines from quarterly to minute-level precision, and focusing on specific local impacts of extreme weather [3]. - The establishment of a multi-departmental liaison system for meteorological disaster warnings has been implemented, enhancing coordination and response efficiency across various sectors [2][3]. Group 3: Forecasting Accuracy - The accuracy of 24-hour urban weather forecasts and temperature predictions has exceeded 80%, with significant improvements in rainfall forecasting accuracy by 10% compared to the previous five-year period [5]. - The spatial resolution of the forecasting system has been refined to 5 kilometers globally and 1 kilometer nationally, with key areas achieving a resolution of up to 100 meters [5]. - The error margin for 24-hour typhoon path forecasts has been minimized to 62 kilometers, maintaining an internationally advanced standard [5].
