Abstract

The developed two-dimensional thermodynamic model of the annual cycle of the ice hummock evolution is presented. Within the framework of the model, test calculations of the evolution of a small ice hummock are carried out for natural conditions of the Kara Sea. The results of freezing calculations demonstrate an influence of the asymmetry of morphometric parameters of the ice hummock and the uneven occurrence of snow layers on the consolidated layer. The results of the ice hummock melting calculations demonstrated an effect of smoothing the sail and the keel of the hummock. All presented calculation results do not contradict field observations.

冰丘（冰脊）演化的二维热力学模型

摘要

介绍了冰丘演化年循环的二维热力学模型。在模型的框架内，针对喀拉海的自然条件，对小冰丘的演化进行了试验计算。冻结计算结果表明冰丘形态参数的不对称性和固结层上雪层出现不均匀的影响。冰丘融化计算的结果证明了使帆和丘丘的龙骨平滑的效果。所有呈现的计算结果与现场观察不矛盾。
