追风逐雨测风云——记一线气象工作者
Jing Ji Ri Bao· 2025-12-08 06:54
天气预报从来不是简单的"看云识天气",而是一场与自然规律的持久博弈。面对短临强对流天气 的"猝不及防"、气候变化带来的极端天气频发等难题,气象工作者从未停下攻坚克难的脚步。他们组建 科研团队,进行数值预报模式研发,让预报时效从小时级向分钟级延伸;他们与陆海空天一体化观测共 同成长,让智慧气象服务平台实现预报预警信息精准推送……这背后是他们无数个日夜的钻研与坚守。 为了让天气预报更准一些,他们在平凡的岗位上书写着不平凡的人生,为人民群众的美好生活贡献 力量。 坚持百分百努力 天气预报可不可以更准? 国家气候中心首席预报员高辉的答案是:"天气预报不可能100%准确,但我们在付出100%的努 力。" 节奏是跳跃的,压力是常态的,责任更是重大的。高辉这样描述首席预报员的工作状态:"很多时 候,思维的切换必须在瞬间完成。短短一个上午,可能刚与华南的同事会商完台风动态,紧接着就要转 向华北研判高温干旱,或是和西南的同事会商秋雨。" 而他和天气打交道,源于一场滞留。1998年盛夏,长江流域发生罕见特大洪涝灾害。高辉陪着因铁 路受损返乡无望的舍友,在宿舍里听了半个月的风雨声。"那时我就想,如果能提前一个月,甚至更早 预见这种 ...

Core Viewpoint - The article highlights the significant advancements in weather forecasting due to the development of China's "Fengyun" meteorological satellites, emphasizing the dedication of academic figures like Xu Jianmin in improving weather prediction accuracy and the broader applications of meteorological data [1][21]. Group 1: Importance of Meteorological Satellites - Meteorological satellites have transformed weather forecasting from general predictions to precise, time-specific forecasts [1]. - The accuracy of weather predictions has greatly improved due to satellite monitoring, although challenges remain in predicting small-scale weather phenomena like tornadoes [3][5]. - Xu Jianmin's lifelong habit of analyzing cloud images reflects the commitment to understanding atmospheric dynamics [4][5]. Group 2: Historical Context and Development - The push for developing China's own meteorological satellites was catalyzed by a severe weather disaster in 1969, leading to a realization of the country's technological lag in weather forecasting [7][8]. - The first successful launch of China's Fengyun-1A satellite in 1988 marked a significant milestone in the country's meteorological capabilities [9][10]. Group 3: Scientific Approach and Challenges - Xu Jianmin documented over 40,000 words of mathematical formulas to address the issue of cloud image shaking in the Fengyun-2 satellite, showcasing the rigorous scientific approach taken to solve complex problems [13][14][16]. - The team faced significant challenges in developing accurate satellite data, requiring extensive research and collaboration to derive correct mathematical models [15][16]. Group 4: Broader Applications of Meteorological Data - The application of meteorological satellites extends beyond weather forecasting to include disaster monitoring and management, as demonstrated during the 1987 Daxing'anling forest fire [18][19]. - Xu Jianmin's foresight in utilizing satellite data for various applications has proven invaluable in emergency response and environmental monitoring [19][20].
