Jamie Ward, PhD, is a CIGLR postdoctoral fellow working with Yi Hong, PhD, and Ayumi Fujisaki-Manome, PhD, and the NOAA-GLERL Bipartisan Infrastructure Law (Lauren Fry, PhD, leads the BIL-SA effort): Subseasonal to Annual (BIL-SA) group to advance our understanding of atmospheric influences on Great Lakes water supply, and how we can use this information to improve future water level forecasting. Before joining CIGLR, Jamie investigated Arctic sea ice dynamics in global climate models at York University (2021-2022; Toronto, Ontario) and the regional variability of extratropical cyclone impacts on Antarctic sea ice at the University of Michigan (2020-2021) as a postdoctoral researcher. As a graduate student in the University of Michigan’s department of Climate and Space Sciences and Engineering, Jamie studied atmosphere-ice sheet interactions over the Greenland Ice Sheet using model output, reanalysis data, and satellite observations.

Research Interest/Area of Expertise:

I use a combination of climate model, reanalysis, and observational data to research the effects of atmospheric on ice sheets, sea ice, and Great Lakes water supply.

    • How are Great Lakes regional precipitation, evaporation, and runoff processes affected by planetary- and synoptic-scale atmospheric circulation mechanisms?
    • How do global climate models represent sea ice drift in the Arctic? How will sea ice drift patterns change in the future?
    • How does cyclone geography in the Southern Ocean impact moisture transport and surface energy fluxes over sea ice? How do these processes affect sea ice growth?
    • How does historical Greenland blocking affect surface energy balance and snowmelt processes on the Greenland Ice Sheet? How will these processes change in different future warming scenarios?
    • How are Greenland Ice Sheet surface energy flux and snowmelt processes affected by black carbon suspended in the atmosphere and deposited on the snow?
