Abstract

Tides play an important role in the mesoscale sea level variability in the Arctic seas. A distinctive feature of tides in this region is the seasonal variability of harmonic constants, which is caused by changes in hydrometeorological conditions during a year. Based on the analysis of long-term hourly sea-level observations in the White, Chukchi, and Laptev seas, the seasonal variability of the main tidal harmonic constants and some nonharmonic tidal characteristics are studied. The use of multiyear observation series allowed calculating the mean amplitudes and phases of tidal harmonics in certain months with high precision and estimating their interannual variability. Significant differences are also found in the pattern and magnitude of seasonal variability both between stations and between the White Sea and the Eastern Arctic.

俄罗斯北极海中潮汐海平面涛动的季节性变化特征

摘要

潮汐在北极海域中尺度海平面变化中起重要作用。该区域潮汐的一个显着特征是谐波常数的季节性变化，这是由一年中水文气象条件的变化引起的。基于对怀特海，楚科奇海和拉普捷夫海的长期每小时海平面观测数据的分析，研究了主要潮汐谐波常数的季节性变化和一些非谐波潮汐特征。通过使用多年观测系列，可以高精度地计算某些月份中潮汐谐波的平均振幅和相位，并估算其年际变化。在台站之间以及白海和东北极地区之间，季节变化的模式和强度也存在显着差异。
