英偉達團隊推出 AI 模型 StormCast，精準預測幾公里內雷暴天氣
英偉達研究團隊開發的“StormCast”AI模型，能在幾公里精度範圍內預測雷暴天氣，顯著提升氣象預測的準確性和全面性。該模型結合生成模型和多垂直層大氣狀態技術，模仿氣象局HRRR模型，每小時更新預測，準確預測輕度、中度和重度降雨概率，尤其關注大氣最低層動態。StormCast在雷暴細胞發展、氣流等方面表現突出，通過創建集合預測，其表現超過單一HRRR模型，爲高分辨率、AI輔助的天氣預測鋪平道路。研究團隊正致力於提高模型訓練數據量和區域範圍，以及改進集合預測的校準，以進一步推動氣象預測技術的發展，減少雷暴天氣帶來的損失和傷亡，並在局地氣候預測中展現應用潛力。
