New Delhi, Dec 8 (NationPress) Google’s DeepMind team has introduced an innovative AI model for weather forecasting known as GenCast, which has successfully outperformed the world's premier weather forecasting system.
According to a paper published in the journal Nature, the researchers at DeepMind reported that GenCast excels beyond the European Centre for Medium-Range Weather Forecasts’ (ECMWF), recognized as the top operational forecasting system globally.
Google stated, “The new AI model enhances the prediction of weather uncertainties and risks, providing quicker, more precise forecasts up to 15 days in advance.”
As per the technology giant, GenCast signifies a significant leap in AI-driven weather forecasting, building upon its earlier deterministic weather model, which offered a single best estimate of forthcoming weather conditions.
In contrast, a GenCast forecast includes an ensemble of 50 or more predictions, each illustrating a potential weather pathway.
GenCast is categorized as a diffusion model, a type of generative AI model that has facilitated recent advancements in image, video, and music creation.
However, GenCast distinguishes itself by being tailored to the spherical geometry of the Earth, learning to accurately generate the complex probability distribution of future weather scenarios when provided with the most recent weather state as input, as explained by Google.
Enhanced accuracy in predicting extreme weather risks can aid authorities in protecting more lives, minimizing damage, and conserving financial resources.
“Take tropical cyclones, commonly referred to as hurricanes and typhoons. Receiving improved and advanced alerts regarding their landfall is invaluable. GenCast offers superior predictions of the trajectories of these perilous storms,” Google commented.
The company plans to soon release real-time and historical forecasts from GenCast, along with previous models, allowing anyone to incorporate these weather inputs into their own models and research workflows.
GenCast is part of Google’s expanding collection of next-generation AI-based weather models, which includes Google DeepMind’s AI-driven deterministic medium-range forecasts and Google Research’s NeuralGCM, SEEDS, and flood models.
