Google DeepMind’s machine learning model, GraphCast, has outperformed traditional weather forecasting methods, including the Integrated Forecasting System (IFS) used by the European Centre for Medium-Range Weather Forecasts (ECMWF). GraphCast accurately predicted weather 10 days in advance in over 90% of cases, making it valuable for predicting extreme weather events. The model, which uses machine learning-based weather prediction (MLWP), analyzes historical weather data to identify patterns and generate predictions. While MLWP does not have the same level of detail as traditional models, it provides faster and more accurate results. Google DeepMind plans to make GraphCast open source and it is already being used by ECMWF.
Google’s GraphCast Model: Revolutionizing Weather Forecasting
Traditional weather forecasting methods have been surpassed by Google DeepMind’s machine learning model, GraphCast. In early testing, GraphCast outperformed the Integrated Forecasting System (IFS) model used by the European Centre for Medium-Range Weather Forecasts (ECMWF) in predicting weather 10 days in advance. GraphCast achieved higher accuracy and faster results in over 90% of verification targets.
Practical Solutions and Value
GraphCast’s impact goes beyond knowing whether to bring an umbrella to work. It excels in accurately predicting extreme weather events, enabling better resource deployment and emergency services planning. For example, GraphCast correctly predicted Hurricane Lee’s landfall in Nova Scotia three days before the IFS model did, allowing for more effective preparations.
GraphCast’s state-of-the-art AI model delivers 10-day weather forecasts with unprecedented accuracy in under one minute. It can even predict the potential paths of cyclones further into the future.
How GraphCast Works
Unlike traditional models that rely on numerical weather prediction (NWP) and complex equations processed by supercomputers, GraphCast uses machine learning-based weather prediction (MLWP). It is trained on 50 years’ worth of historical weather data and looks for patterns in the data instead of creating a model of the atmosphere. By finding subtle patterns that fixed equations cannot detect, GraphCast makes predictions based on current weather conditions.
While GraphCast’s level of detail may not match traditional models, it offers significantly higher accuracy and speed. While supercomputers take hours to process weather data, GraphCast produces results in less than a minute.
Integration with Existing Methods
GraphCast does not replace traditional NWP models but complements them. MLWP relies on historical data produced by NWP models. By using GraphCast alongside current methods, meteorological organizations can predict extreme weather events faster and more accurately.
Google DeepMind has made GraphCast open source, and ECMWF is already utilizing it.
