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].
