Examining the Impact of Great Lakes’ Temperature Perturbations on Simulated Downwind Precipitation

How do water temperature changes on the Great Lakes affect modeled downwind precipitation? Two Atmospheric Sciences students, Jess Langlois and Lauren Cornell, just completed their summer internship to answer that question. Over a seven-week period, they worked with Dr. Hanrahan to analyze simulated rainfall data obtained from the Weather Research and Forecasting (WRF) model. Several simulations were completed to assess the sensitivity of precipitation in New England to changing water temperatures of the Great Lakes. Their work will inform the configuration of the regional climate model which will be used to downscale future global climate model simulations under human-caused climate change. As members of the BREE (Basin Resilience to Extreme Events) Climate Modeling Team, Jess and Lauren presented their work at Plymouth State University and Dartmouth College. They also plan to present results at the American Geophysical Union Fall Meeting this upcoming December.

Jess and Lauren also practiced presenting their research to faculty and staff at Northern Vermont University-Lyndon:
