Preparation of Initial Data for the Thermodynamic Modeling of Arctic Ice

O. M. Andreev and D. V. Drabenko

The problem of preparing initial climatic data with varying frequency of occurrence for thermodynamic modeling of Arctic ice is considered. It is revealed that air temperature is the most significant meteorological parameter for such calculations. Based on the estimation of the sum of freezing degree-days for the cold season, a method for preparing initial data for the thermodynamic calculation of parameters of growing ice of rare occurrence is presented. The test calculations performed for the areas with long-term series of field observations demonstrated a good agreement between the calculated and measured ice thickness both for the medium and extreme climatic conditions. It is stated that similar calculations of ice parameters can be carried out almost for any region of the Arctic.
