EPT-1.5在风速和辐射预测上超越主流模型，刷新气象预测新纪录
EPT-1.5 Technical Report
- 基于地球物理变换器架构，专为欧洲能源行业设计
- 风速预测优于GraphCast、FuXi、Pangu-Weather及ECMWF IFS HRES
- 适合能源领域需高精度气象预测的场景
我们宣布发布EPT-1.5，这是地球物理变换器（Earth Physics Transformer, EPT）系列最新版本的基础型人工智能地球系统模型。相较于前代EPT-1，EPT-1.5在能源相关变量预测上实现显著提升，尤其在10米与100米风速及太阳辐射预测方面表现突出。在风速预测任务中，其性能超越现有AI天气模型（如GraphCast、FuXi、Pangu-Weather）以及欧洲中期天气预报中心（ECMWF）的领先数值模型IFS HRES，创下新的基准水平。
原文摘要 · Abstract (English)
We announce the release of EPT-1.5, the latest iteration in our Earth Physics Transformer (EPT) family of foundation AI earth system models. EPT-1.5 demonstrates substantial improvements over its predecessor, EPT-1. Built specifically for the European energy industry, EPT-1.5 shows remarkable performance in predicting energy-relevant variables, particularly 10m & 100m wind speed and solar radiation. Especially in wind prediction, it outperforms existing AI weather models like GraphCast, FuXi, and Pangu-Weather, as well as the leading numerical weather model, IFS HRES by the European Centre for Medium-Range Weather Forecasts (ECMWF), setting a new state of the art.
