微软发布Aurora 1.5：扩展开放天气基础模型，新增集合预报
原标题：Aurora 1.5: Extending open foundation models for weather and Earth-system applications
AI 摘要
微软发布了Aurora 1.5，这是其地球系统基础模型的主要扩展，新增22个天气变量、每小时时间分辨率和概率集合预报，并作为开源模型在GitHub和Hugging Face上发布。该模型由微软天气团队开发，基于微软研究院AI for Science的原始模型，旨在连接开放研究与企业级天气服务。Aurora 1.5的集合预报在88.9%的评估目标上优于ECMWF动力集合，并显著降低了热带气旋的路径误差。
