Hurricane Katrina killed hundreds of people as it made landfall on New Orleans in 2005 - many of these deaths could have been avoided if alerts had been given one day earlier. Accurate weather forecasts are really life-saving.

๐Ÿ”ฅย Now, NASA and IBM just dropped a game-changing new model: the first ever foundation model for weather! This means, it's the first time we have a generalist model not restricted to one task, but able to predict 160 weather variables!

Prithvi WxC (Prithvi, โ€œเคชเฅƒเคฅเฅเคตเฅ€โ€, is the Sanskrit name for Earth) - is a 2.3 billion parameter model, with an architecture close to previous vision transformers like Hiera.

๐Ÿ’กย But it comes with some important tweaks: under the hood, Prithvi WxC uses a clever transformer-based architecture with 25 encoder and 5 decoder blocks. It alternates between "local" and "global" attention to capture both regional and global weather patterns.

๐—ž๐—ฒ๐˜† ๐—ถ๐—ป๐˜€๐—ถ๐—ด๐—ต๐˜๐˜€:
๐Ÿ”ฎ Nails short-term forecasts - Prithvi WxC crushed it on 6-12 hour predictions, even outperforming some traditional numerical weather models
๐ŸŒ€ Tracks hurricanes like a champ - For Hurricane Ida, it predicted the landfall location within 5 km (vs 20+ km errors from other AI models), which is a huge progress!
๐Ÿ” 6x downscaling power - Can zoom in on weather data to 6x higher resolution with 4x lower error than basic methods
๐ŸŒŠ Models elusive gravity waves - Accurately simulates these crucial but hard-to-capture atmospheric oscillations

As climate change intensifies, tools like Prithvi WxC will become more and more crucial to avoid disasters!
