Seasonal & Sub-Seasonal Tropical Cyclone Forecasts


Colorado State University has issued forecasts of Atlantic basin hurricane activity for over 37 years. Following the pioneering work of Prof. William Gray, our group continues the long CSU tradition in forecasting with continually improving techniques for predicting tropical cyclone activity powered by new research.

Tropical Weather and Climate Research


We conduct cutting-edge research to advance knowledge and prediction of the weather and climate system. Our research group is focused on improved understanding and prediction of tropical weather, including hurricanes and typhoons, extreme rainfall, and other high impact weather.

Ting-Yu Cha receives third place in Wagner Memorial Award competition

Ph.D. student Ting-Yu Cha received third place in the Peter B. Wagner Memorial Award for Women in Atmospheric Sciences competition. The paper she submitted, “Polygonal Eyewall Asymmetries During the Rapid Intensification of Hurricane Michael (2018)”, highlights the importance of coastal radar observations with high temporal resolution and the single Doppler radar wind retrieval algorithm, which can help to improve tropical cyclone intensity forecasts and investigate real-time TC intensity and structure changes.

This paper also was selected as an Editors’ Highlight by Eos in 2020. Cha’s co-authors on the paper were her adviser, Professor Michael Bell, Wen-Chau Lee and Alex DesRosiers.
