Use of satellite imagery, flight data and machine learning to forecast atmospheric conditions with enough skill to drive operational decisions.
Google DeepMind's WeatherNext Cyclones gives hurricane forecasters about an extra day of accuracy on average, according to a Nature study of past storms. So far it has one live season on record, and that season is what forecasters will lean on when the next storm strengthens fast.

AI weather models that rival physics systems globally lack the storm data to foresee jumps like Hurricane Polo's 24-hour rise to Category 5, a researcher says. The author's own research suggests chaos may still cap long-range forecasts even with better data.

Operation Blue Skies will spend 30 months testing whether Google's contrail predictions are good enough for NATS controllers to shift aircraft 2,000ft over the North Atlantic.

Google's new model trains on sparse station observations instead of six-hour-old physics output, which is what buys the 5 km surface grid. Wind aloft still comes out at 25 km, the same as WeatherNext 2.

The Swiss team now has the two things an AI hazard model needs, a full Earth observation archive and a top-tier machine, in the same room. Nobody has reported the forecast skill that pairing is meant to buy.
Reality
Google's satellite analysis puts the avoided warming at about 40%, with more than half of it coming from the Hong Kong to Singapore corridor, which is a better guide to where this pays than the trial's ultra-long-haul billing.

Google DeepMind says the model resolves temperature at 5 kilometres and updates every hour, and it hands the headline accuracy claim to an outside evaluator, Brightband, whose scores the announcement does not publish.
Reality
The model feeds Search, Maps and Gemini and ships on Google Cloud, so anyone whose product depends on a forecast now has a supplier to choose and an accuracy claim from a startup's benchmark to read closely.

A five-season Atlantic study led from the University of Miami found ECMWF's AI ensemble carrying more tropical cyclogenesis signal at 84 to 120 hours and less at 36 to 48, which makes it guidance rather than a substitute.

The odds now favour a record season. The AI forecasting being pitched at the countries with the least margin is the least tested on exactly that kind of event.
