HiRO-ACEv2：以 3 km 分辨率低成本模拟极端天气
HiRO-ACEv2: Simulating extreme weather at 3 km resolution for a fraction of the cost
AllenAI 发布 HiRO-ACEv2，可在 3 km 分辨率下模拟极端天气，成本仅为常规方法的一小部分。模型基于 X-SHiELD 模拟数据训练，官方提供网页演示，将 HiROv1、HiROv2 与 X-SHiELD 的降水、风场和海平面气压输出并排对比，模型已开放下载并配有教程 notebook。

Visualizing and using HiRO outputs
Simulated 10 m wind speed over Baja California in the ACE data visualizer: ACE2 at 100 km resolution on the main map and HiRO-ACEv2 at 3 km in the inset.
A simulated storm over the northeastern Pacific in the ACE data visualizer. The main map shows 10 m wind speed at 100 km resolution; the 3 km HiRO-ACEv2 inset shows finer structure within the storm.
To make it easy to see what HiRO produces without running any inference, we built a web demo that shows pre-generated precipitation, wind, and sea-level pressure output from HiROv1 and HiROv2 side by side with X-SHiELD, the simulation they were trained on. The demo complements the quantitative comparisons in our tech report: it offers a quick visual check of how the outputs look, and lets users zoom in on their own region of interest to judge performance there.
For more in-depth analysis, the models are available to download , and our tutorial notebooks walk through how to run them.
