Google DeepMind has introduced a new AI model named GenCast, which significantly advances weather forecasting capabilities. Published in Nature, GenCast delivers state-of-the-art accuracy in predicting weather conditions up to 15 days in advance, surpassing traditional methods in both everyday and extreme weather forecasts. The model was trained on four decades of historical weather data and can generate forecasts in just 8 minutes, compared to hours on supercomputers. GenCast not only outperforms leading forecast providers 97% of the time but also provides probabilistic forecasts, offering insights into the likelihood of various weather scenarios. This technology promises to revolutionize how we prepare for weather changes, with potential applications in other domains like medicine.
