GraphCast AI is a machine learning-based method for medium-range global weather forecasting, developed by DeepMind and Google. It uses graph neural networks (GNNs) to learn the complex physical dynamics of fluids and other materials from reanalysis data. GraphCast AI can predict hundreds of weather variables, over 10 days at 0.25 degree resolution globally, in under one minute. It outperforms the most accurate operational deterministic systems on 90% of 1380 verification targets, and its forecasts support better severe event prediction, including tropical cyclones, atmospheric rivers, and extreme temperatures.
GraphCast AI has significant implications for the products industry, as it can help improve decision-making across many social and economic domains that depend on accurate and efficient weather forecasting. For example, GraphCast AI can help optimize crop yields, reduce energy consumption, enhance public health, and mitigate the impacts of natural disasters. GraphCast AI also demonstrates the promise of machine learning for modeling complex dynamical systems, and opens up new possibilities for exploring other domains such as climate change, air quality, and traffic flow.
