Abstract

In this work we analyze the influence of frontal zone dynamics on the generation and distribution of short-period internal waves (SIWs) in the Barents and the Kara Seas during an ice-free season based on analysis of satellite data. In the Barents Sea, marginal ice frontal zone and polar front zone are considered. They occupy up to 8 % of the total sea area. As shown, only 5 % of the total number of internal wave manifestations were recorded inside these frontal zones. In July, their number reaches 18 % in the marginal ice frontal zone. In the Kara Sea, estuarine and marginal ice frontal zones are considered, covering areas up to 10 % of the entire sea. On average, 18 % of the total number of SIW manifestations were observed inside frontal zone regions of the Kara Sea. The maximum number of internal waves (33 %) is observed in August in the most dynamic estuarine frontal zone, associated with the Ob and the Yenisei river runoff. Factors that determine the features of the space-time distribution of shortperiod internal waves in the regions of pronounced frontal dynamics are discussed.
