Researchers have introduced GraphCast, a state-of-the-art AI model for global weather forecasting that can predict weather conditions up to 10 days in advance with unprecedented accuracy. GraphCast uses machine learning and Graph Neural Networks to process spatially structured data and can provide earlier warnings of extreme weather events. The model is trained on decades of historical weather data and can make forecasts in under one minute, outperforming traditional numerical weather prediction systems. The researchers have open-sourced the model's code to enable scientists and forecasters to benefit from it.
