GENCAST AI

PRELIMS 

• Google DeepMind has launched the GenCast AI model for weather forecasting.
• GenCast AI claims better accuracy and extended forecasting range than existing models.
• It uses ensemble forecasting, similar to traditional numerical weather prediction (NWP).
• Unlike NWP, GenCast AI is powered by AI rather than simulations.
• Ensemble forecasting employs an NWP model with different starting conditions to predict a range of possible weather outcomes.
