品玩7月6日讯，日前，国际顶级学术期刊《自然》（Nature）杂志正刊登载了华为云盘古大模型研发团队的研究成果 ——《三维神经网络用于精准中期全球天气预报》（Accurate medium-range global weather forecasting with 3D neural networks）。
目前盘古气象大模型能够提供全球气象秒级预报，预报结果包括位势、湿度、风速、温度、海平面气压等多项信息，可直接应用于多个气象研究细分场景。
盘古大模型研发团队发现，当前 AI 气象预报模型的精度不足主要有两个原因：一是原有 AI 气象预报模型都是基于 2D 神经网络，无法妥善处理不均匀的 3D 气象数据；二是 AI 方法缺少数学物理机理约束，因此在迭代的过程中会不断积累迭代误差。
为此，该团队提出采用适应地球坐标系统的三维神经网络来处理复杂的不均匀 3D 气象数据，并且使用层次化时域聚合策略来减少预报迭代次数，从而减少迭代误差。
