Abstract
Global climate models have pointed to the polar regions as very sensitive
areas in response to climate change. However, these models often do not
contain representations of processes peculiar to the polar regions such as
dynamic sea ice, permafrost, and Arctic stratus clouds. Further, global
models do not have the resolution necessary to model accurately many of the
important processes and feedbacks. Thus, there is a need for regional
climate models of higher resolution. Our such model (ARCSy M) has been
developed by A. Lynch and W. Chapman. This model incorporates the NCAR
Regional Climate Model (RegCM2) with the addition of Flato–Hibler cavitating
fluid sea-ice dynamics and Parkinson–Washington ice thermodynamic
formulation. Recently work has been conducted to couple a mixed-layer ocean
to the atmosphere–ice model, and a three-dimensional (3-D) dynamical ocean
model, in this case the S-Coordinate Primitive Equation Model (SPEM), to the
ice model. Simulations including oceanic circulation will allow
investigations of the feedbacks involved in fresh-water runoff from sea-ice
melt and sea-ice transport. Further, it is shown that the definition of the
mixed-layer depth has significant impact on ice thermodynamics.
