Core Viewpoint - The article highlights the advancements in meteorological support for China's polar scientific expeditions, particularly focusing on the "Mazu" ocean environment forecasting system, which enhances the accuracy and timeliness of weather predictions for maritime operations in extreme conditions [4][6][12]. Group 1: Technological Innovations - The "Mazu" system includes multiple sub-models for ocean circulation, waves, and sea ice, significantly improving the precision of wave forecasts through a hexagonal grid framework [4][6]. - The "Mazu·Wave" model can achieve GPU parallel acceleration, allowing for effective warnings about wave disasters 5 to 7 days in advance [6][8]. Group 2: Operational Enhancements - The meteorological support team can now predict cyclone formation, movement, and intensity changes 5 to 7 days ahead, allowing for more flexible and intelligent navigation strategies through the challenging "Roaring Forties" [9][11]. - The "Snow Dragon" vessel employs various crossing strategies based on real-time weather conditions, enhancing safety during expeditions [11]. Group 3: Historical Context and Evolution - Since the first Antarctic expedition in 1984, China has transitioned from hand-drawn weather maps to advanced autonomous technologies for weather observation, significantly improving the stability and reach of polar research missions [12].

原来，"妈祖"是我国自主研发的全谱系海洋环境预报系统的代号，包含海洋环流、海浪、海冰等多个子 模型。其中，"妈祖·海浪"模型采用基于六边形非结构网格的有限体积平流动力框架，可以更精确模拟 海浪变化，大幅度提升预报精度和时效。 新华社北京/"雪龙"号11月17日电 题：看浪听风观云：自主创新为极地科考保驾护航 新华社记者顾天成、徐鹏航 海浪、海风、海冰等海洋自然灾害，常给人类生活生产造成巨大损失，也是执行极地科考任务的潜在挑 战。 自20世纪80年代中国开启极地科学考察以来，每一艘科考船、每一座科考站都有气象保障团队。近年来 我国加大海洋灾害预警、预报技术和设备投入，一批自主研发技术和设备广泛应用于极地考察。 听风、看浪、观云，科技创新为中国第42次南极考察队保驾护航。 更精确模拟海浪变化 "妈祖"——在"雪龙"号上，气象预报员讨论未来海况时，常提到这样一个关键词。 这一在中国沿海地区备受敬仰的"守护者"与气象预报有何联系？ "传统框架好比一张固定尺寸的网，而六边形框架能自由加密，捕捉到更精细的海洋变化。""雪龙"号气 象预报员、国家海洋环境预报中心研究员张蕴斐说。 实践证明，"妈祖·海浪"数值预报模式可实现G ...
