Surface temperatures across the Arctic are increasing at nearly twice the rate of the global mean in response to natural and forced climate change, known as “Arctic Amplification”. This warming is further magnified as a result of positive feedbacks in the climate system.
Evaluating the effects of melting sea ice as a result of Arctic Amplification can affect planetary vertical wave propagation from the troposphere into the stratosphere and have important implications on the magnitude and location of the polar vortex. By understanding this complex relationship, we may be able to better simulate and detect changes in the prevalence of extreme weather events in the midlatitudes, particularly across the northeastern United States.,,
For my PhD research, I am working in Dr. Gudrun Magnusdottir’s Research Group to apply a series of GCM ensemble experiments to understand the dynamics and relative forcings of natural and anthropogenic climate change on this high latitude circulation and resultant teleconnection.

 Most atmospheric general circulation model (AGCM) experiments assessing the linkages between sea ice anomalies and atmospheric teleconnections prescribe SIT as a constant (usually 2-m). Here we evaluate the influence of realistically representing the magnitude and spatial pattern of SIT. Further, we conducted idealized experiments (WACCM4) to isolate the role of thinning sea ice vs. sea ice concentration on the atmosphere. [GitHub Repository]
