DeepMind’s hurricane breakthrough has surprised weather scientists
Open source WeatherNext model can make accurate predictions with lower-resolution weather data.
TL;DR
- Google's WeatherNext AI model predicts cyclones with unprecedented accuracy and provides an extra day of lead time.
- The model accurately predicted Hurricane Melissa as a Category 5 hurricane five days before landfall, allowing for earlier warnings.
- WeatherNext's predictions three days out are as accurate as previous models' predictions two days out.
- The AI model was trained on both general weather data and cyclone data due to the rarity of extreme events.
- It can predict both storm track and intensity, a significant improvement over previous AI models that struggled with intensity.
- Researchers are surprised by the model's accuracy using lower-resolution atmospheric data.
- The AI model produces a range of potential scenarios, capturing potential 'butterfly effects'.
- Google is open-sourcing the WeatherNext models to encourage further research and insights into cyclone behavior.
