Abstract

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.

为北极冰热力学建模准备初始数据

摘要

考虑了为北极冰热力学建模准备具有不同发生频率的初始气候数据的问题。结果表明，气温是进行此类计算的最重要的气象参数。基于对寒冷季节冰冻天数天总数的估计，提出了一种为稀有生长冰参数热力学计算准备初始数据的方法。对于具有长期野外观测结果的区域进行的测试计算表明，在中等和极端气候条件下，计算出的冰厚与实测冰厚之间具有良好的一致性。据指出，几乎可以对北极的任何地区进行冰参数的类似计算。
