| Abstract: |
I am interested in looking at the high-latitude response of current coupled climate models to greenhouse gas warming. In particular I am interested in their simulation of the current climate, their seasonal cycle and their response to increased CO2 in the atmosphere in the decades to come. Variables that I am interested in include the sea ice thickness, concentrations, and ocean and atmospheric variable that will allow me to construct a fresh and heat budget of Arctic sea ice.
Things that I am particularly interested in is to quantify the relative role of 1- the increased LW down in a warmer climate, 2- the change in wind forcing (i.e. a warmer arctic may be accompanied by lower SLP and wind pattern that will export more or less ice out of the Arctic), and 3- the change in ocean heat transport into the Arctic, in reducing the sea-ice thickness and concentrations in the Arctic in the future.
This project also links nicely with another project I have on the role of the ocean on the Fresh Water Budget of the Arctic (funded by the Fresh Water Initiative - NSF OPP). |
