Google's AI weather model update improves forecast accuracy

Ars Technica notes that Google is one of the major players in AI weather forecast models. Such models offer forecast performance similar to traditional models while requiring far less computing power, which means they can be run more frequently.

Many weather models use reanalysis, a type of model that combines a variety of weather data into a single, consistent global snapshot of the atmosphere. Reanalyses must estimate conditions over locations without real-world measurements because weather forecast models need to work with a global picture.
