The researchers didn’t investigate its performance on precipitation - a major weather variable and one of the trickiest to accurately capture in models. Still, Pangu-Weather has some limitations. And it’s even slightly more accurate than the European Centre for Medium-Range Weather Forecasts, one of the world’s leading weather centers. It’s able to accurately track the pathway of tropical cyclones, the researchers found. Ltd., the model is capable of yielding results up to 10,000 times faster than conventional models. Developed by researchers at the Chinese technology company Huawei Technologies Co. The first paper describes a model dubbed Pangu-Weather - it forecasts different global weather variables, such as temperature and wind speed, up to about a week in advance. Still, the new Nature papers suggest the world of AI weather forecasting is swiftly developing. These are issues AI experts are still investigating. That could make it difficult for AI weather models to accurately simulate unprecedented, record-breaking events. But certain kinds of weather events, such as heat waves and hurricanes, are growing more intense as the planet warms - and in some cases, they’re becoming so extreme that there are few examples at all in the historical record. But experts caution that the changing climate may pose a unique challenge for burgeoning AI weather models.ĪI systems rely on historical weather data to teach them how to produce accurate forecasts.
