Welcome to Learning English, a daily 30 minute program from the Voice of America.

I'm Ashley Thompson. And I'm Mario Ritter Jr. This program is

designed for English learners so we speak a little slower and we use words and phrases especially written for people learning English.

Today Brian Lynn has a report on how artificial intelligence may help improve

weather predictions. Anna Mateo presents this week's Health and Lifestyle Report, and we close the show with the lesson of the day.

But first.

Weather researchers are using artificial intelligence, AI systems to improve existing weather prediction methods. But experts say the AI tools currently

face limitations and should be used along with traditional

prediction methods to be most effective.

AI systems trained to predict or forecast weather events are now being used by many

government agencies and organizations worldwide.

Such systems aim to produce weather predictions faster and at a lower cost than traditional forecasting methods.

One weather-predicting system that has shown promise is the Google financed Graphcast method.

This machine learning based system trains directly on weather data that has already been collected and examined.

Such methods have demonstrated an ability to outperform traditional forecasting systems.

The system works by combining past weather predictions with modern forecasting models to provide the most complete

picture of weather and climate.

In Europe, the European Center for Medium Range Weather Forecasts, ECMWF has been using

AI prediction tools since January.

The organization provides detailed weather forecasts

four times per day to nations across Europe.

The ECMWF technology is called the Artificial Intelligence
