Assessing the Sensitivity of the WRF-ARW Modelto the Methods of Arctic Ice Cover Description

V. I. Bychkova, K. G. Rubinshtein, and A. P. Makshtas

Compared are several experiments with the polar version of the WRF-ARW model. In one case, ice characteristics (concentration and temperature) are provided by the GFS (Global Forecasting System) center, and in the other case, are obtained using the ice model of Arctic and Antarctic Research Institute. Determined are the degree of sensitivity of the WRF-ARW regional hydrodynamic model to the different methods of ice cover description and their effects on the forecast of surface meteorological parameters in the Arctic. Presented are the skill scores of numerical forecasts obtained using different sources of data on ice surface thermophysical characteristics.
