ECE professor develops AI-driven method to improve forecasts weeks in advance
Haonan Chen, a CSU associate professor of electrical and computer engineering, and his team have published new research that could improve the accuracy of precipitation forecasts up to two weeks in advance.
The paper was recently published in Nature Partner Journals. It introduces a novel artificial intelligence framework that generates multiple possible rainfall scenarios rather than a single prediction. The approach provides a more complete picture of future weather uncertainty and offers better insight into the range of conditions that may occur.
The findings build on Chen’s broader efforts to advance weather prediction using AI.
“While our previous projects focused on improving AI-based short-term forecasting and advancing our understanding of atmospheric processes, this study addresses one of the most challenging forecasting variables: precipitation at medium-range time scales,” said Chen.
By producing an ensemble of possible outcomes, the new framework both improves precipitation forecast accuracy and helps researchers better quantify uncertainty. More reliable precipitation forecasts could support decision-making in areas such as agriculture, water resource management, emergency preparedness and disaster response.
Chen and his research team hope to extend their approach to longer-range forecasts, higher-resolution predictions and additional weather variables.
