Abstract -
The goal of my Ph.D. dissertation research is aimed to develop the multi-scale resolving coupled atmospheric-ocean model by coupling Global-FVCOM with E3SM and
examine and project the impacts of climate change on the interannual variability of Beaufort Gyre circulation and freshwater content. The primary objectives are 1) to identify and qualify the critical physical processes and numerical approaches needed to succeed in projecting the interannual variability of the BGC and FWC; 2) to examine processes and mechanisms of FW accumulation and release in the BG region in the future; 3) to predict the pathways of FW and sea ice from the BG to the subpolar North Atlantic and their changes under different circulation regimes; 4) to project the consequences of FW release from the BG toward subpolar regions (if possible) and impacts on hydrography, deep convection, and circulation. The goal and objectives will be achieved by a) assessing the climate change E3SM prediction; b) coupling Global-FVCOM with E3SM, c) validating the coupled E3SM and Global-FVCOM model, and d) using the validated E3SM and Global-FVCOM coupled model to project the impacts of climate change on the BG and FW content in the Arctic.
