AI models ArchesWeather and ArchesWeatherGen show climate simulation stability

Researchers have evaluated ArchesWeather and ArchesWeatherGen, two machine learning models originally designed for weather forecasting, for their capabilities in long-term climate simulations. When adapted to act as forced atmospheric models using monthly sea surface temperature and sea ice cover data, both models demonstrated stable climate simulations and annual cycles. They successfully captured the drift of climate variables, reproduced ERA5 climatology, and accurately represented large-scale circulations and interannual variability. AI

IMPACT Demonstrates potential for ML models, originally for weather, to contribute to climate simulation research.
