Cameron C. Lee

My main research interests are in climate change and applied climate science, focusing on utilizing synoptic methods in a variety of applications. I am currently PI on a grant from NOAA's Climate Program Office that explores the development of excess heat and excess cold factors as an official monitoring product for NOAA. We recently finished projects from three other federal grants from NASA and two from NOAA; the NASA-funded research applied synoptic methods in the development of a water clarity index as an indicator of climate change in the Great Lakes; one NOAA grant explored various indicators of climate change related to human thermal comfort, while another NOAA grant examined the role of atmospheric circulation in day-to-day sea-level variability. Other previous grant-based research includes assessing the impacts of climate change on hazardous heat events in California, and studying the relationship between synoptic weather types and asthma in New York State, and exploring water clarity along the coast of the Southeastern U.S. Other non-grant related research has included studying the relationship of air pollution to synoptic weather types and atmospheric circulation patterns in Cleveland; the association of circulation patterns to chlorophyll levels near the Florida Gulf Coast, and the impact of transitional weather types on winter mortality. My master's thesis focused on joining synoptic methods with global climate model output data in order to project future tornado day frequency and seasonality in the U.S. My dissertation research focused primarily on the development of a gridded synoptic weather typing classification for the United States, which will be useful in a number of applications. I also serve as the Managing Editor of the International Journal of Biometeorology.
