Using artificial intelligence trained on decades of atmospheric observations and live satellite data, it can generate forecasts much faster while improving the level of detail.

As climate change increases the frequency of extreme weather events, faster forecasting tools are becoming more important than ever. Google believes WeatherNext 3 can help governments, businesses, researchers, and everyday users make better weather-related decisions.

What is WeatherNext 3?

WeatherNext 3 is an AI-powered forecasting system that predicts weather conditions across the globe using machine learning instead of relying entirely on traditional numerical weather prediction methods.

The model analyzes enormous amounts of historical weather data alongside real-time satellite imagery and meteorological observations. It learns weather patterns and produces highly detailed forecasts within minutes.

Google states that WeatherNext 3 significantly improves the prediction of rainfall, temperature, humidity, wind, cloud cover, and other atmospheric variables. It also delivers forecasts with much finer geographical detail than earlier versions.

Why Google Developed WeatherNext 3

Modern weather forecasting is incredibly complex. Traditional forecasting centers use massive supercomputers that continuously solve mathematical equations describing Earth’s atmosphere.
