Abstract

The estimates of statistical indicators of the state and variability of the ice cover characteristics (ice concentration, ice stage of development) of the Bering Sea obtained from digital imagery are presented using available information on ice conditions for the period of 1960–2016. The distributions of average long-term values of the fields of ice concentration and stage of development for the period from 1960 to 2016 are obtained and considered, their spatial-temporal variability is analyzed. The estimates can be used in the analysis of changes in the hydrometeorological regime of the region, in problems of modeling the state of the ice cover, as well as in solving practical issues of economic development of the Bering Sea.

白令海冰浓度和发展阶段的状态和变化

摘要

使用 1960-2016 年期间冰况的可用信息，从数字图像中获得了对白令海冰盖特征（冰浓度、冰层发展阶段）状态和可变性的统计指标的估计。获得并考虑了1960年至2016年期间冰浓度场和发展阶段的平均长期值分布，分析了它们的时空变化。这些估计可用于分析该地区水文气象状况的变化、冰盖状态建模问题以及解决白令海经济发展的实际问题。
