Microsoft Open-Sources Machine Learning Tool to Improve Weather Forecasts Up to 6 Weeks Ahead

Microsoft announced a new machine learning tool that improves medium-range weather forecast accuracy from two to six weeks ahead. Findings were published in Nature, and the tool is available as open-source software.

According to Microsoft, both old-school physics-based forecasting and newer AI models typically become less reliable beyond two weeks. The new tool offers a cost-effective way to improve accuracy in the two-to-six-week window.

Microsoft points to farmers and emergency responders as key beneficiaries, both of which are sensitive to weather variability in the Middle East.

Yes, according to the source the tool is now available as open-source software, allowing researchers and organizations to test and build on it.
