Abstract

Based on the CICE model, the characteristics of the ice cover in the Northern Caspian Sea were simulated during the extreme ice seasons of 2011/2012 (long and cold) and 2015/2016 (short and warm). The characteristics of these seasons (length, frost degree-days, sea ice extent, maximum ice thickness) are given. Composite anomalies of surface air pressure and air temperature were constructed for the Northern Caspian region. Based on the JRA-55 reanalysis data, the concentration and thickness of sea ice were calculated. A comparison of the simulation results with observational data showed that the main differences in ice conditions in these seasons are reproduced satisfactorily.

极端季节里海北部冰盖建模

摘要基于 CICE 模型，模拟了 2011/2012 年（长而冷）和 2015/2016 年（短而暖）极端冰季期间北里海的冰盖特征。给出了这些季节的特征（长度、霜冻度日、海冰范围、最大冰厚）。构建了北里海地区的地面气压和气温综合异常。根据 JRA-55 再分析数据，计算了海冰的浓度和厚度。模拟结果与观测数据的比较表明，这些季节冰情的主要差异得到了令人满意的再现。
