In Boulder, Colorado, scientists have started using new artificial intelligence (AI) weather models to predict the weather. These AI models can make very fast and accurate forecasts, finishing a 14-day world forecast in less than 10 seconds. This work moves much faster than traditional weather forecasting with supercomputers.

The new AI models work by studying years of old weather data, like satellite pictures and past records. By learning from these patterns, the AI does not need to calculate every step using complex physics. This is why it can forecast the weather so quickly.

Because of this new AI technology, more countries may soon get good weather forecasts without needing expensive computers. This can help people prepare for bad weather sooner, giving them more time to be safe.
