Conducting a series of six AMIP-style simulations using a high-top AGCM (WACCM4), we explore the role of various forcings and their linear interference (including sea ice, SST, Eurasian snow cover, and the QBO) on the large-scale circulation response in the last ~40 years. We focus on their potential predictability and also address the relative importance of the stratospheric pathway on the dynamical response to recent Arctic Amplification (1979-2016).

Scripts/: Main Python scripts/functions used in data analysis and plottingrequirements.txt: List of environments and modules associated with the most recent version of this project. A Python Anaconda3 Distribution was used for our analysis. All AGCM experiments were processed through resources on CISL's Cheyenne supercomputer. Tools including NCL, CDO, and NCO were also used for initial data manipulation.
