中国气象局：我国已建成陆海空天一体化综合气象观测系统，能提前15天预测全国性重大天气过程，提前6个月预测全球气候异常事件

Core Insights - The press conference highlighted the high-quality development of meteorology during the "14th Five-Year Plan" period, emphasizing the establishment of a new national system for meteorological technological innovation [1][3]. Group 1: Meteorological Technological Advancements - The meteorological sector has focused on overcoming critical technological challenges, achieving high levels of self-reliance in satellite, radar, and observation technologies [1]. - A comprehensive meteorological observation system has been established, consisting of 9 Fengyun satellites, 842 weather radars, and over 90,000 ground observation stations, with a disaster weather monitoring rate of 83% [1]. - The intelligent digital forecasting system can predict regional heavy rain, high temperatures, and cold waves 3 to 7 days in advance, and major national weather events 15 days ahead, along with global climate anomalies 6 months in advance [1]. Group 2: Emergency Response and Collaboration - The meteorological department has improved its emergency response mechanisms, ensuring that meteorological warnings can be quickly transformed into defensive actions [3][4]. - A new inter-ministerial liaison system for meteorological disaster warnings has been established, allowing for the rapid dissemination of 82 types of warning information across 17 industries, reaching emergency responders within 1 minute [3][4]. - The department has implemented a progressive meteorological service model, refining forecasts from quarterly to minute-level precision, focusing on specific local impacts [4]. Group 3: Forecasting Accuracy Improvements - The meteorological department has developed a self-controlled global and regional numerical forecasting technology system, with the forecast accuracy for the Northern Hemisphere increasing from 7.9 days to 8.1 days [6][7]. - The accuracy of 24-hour urban weather and temperature forecasts has reached over 80%, with significant improvements in heavy rain forecast accuracy by 10% compared to the previous five-year period [7]. - The error in 24-hour typhoon path forecasts has been minimized to 62 kilometers, maintaining international advanced levels [7].
