Microsoft releases open-source AI model for more accurate long-range weather forecasts

Microsoft researchers have developed a machine learning tool designed to improve the accuracy of weather forecasts two to six weeks in advance. The company claims this method addresses a reliability gap common in both traditional physics-based and newer AI models beyond a two-week window. The findings were published in the journal Nature, and the software has been made open-source. The tool aims to help farmers and emergency responders plan with greater certainty, and Microsoft joins firms like Google and Nvidia in developing AI for weather prediction.
