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.
