GenCast

News: Google’s DeepMind has launched GenCast to improve the weather forecasting models. 

About GenCast 

• It is a new Artificial Intelligence based weather forecasting model that can predict weather up to 15 days in advance in just 8 minutes. 
• It displays greater speed and accuracy than traditional weather forecasting systems. 
• Working of GenCast: 
  • It employs probabilistic ensemble forecasting to predict a broad range of possible weather scenarios. 
  • It employs a diffusion model approach to generate multiple forecasts, capturing the complex behaviour of the atmosphere. 
  • To improve forecasting, it has been trained on 40 years of weather data like temperature and wind speeds. 
• It can be used to forecast climate change induced extreme weather events, improving disaster preparedness. 
• Scientists are working on making GenCast’s data publicly available to benefit the larger weather forecasting community.
