МОДЕЛЬНОЕ ИССЛЕДОВАНИЕ МЕЖГОДОВОЙ ИЗМЕНЧИВОСТИ ВОДООБМЕНА ПОЛЯРНЫХ МОРЕЙ С АТЛАНТИЧЕСКИМ И СЕВЕРНЫМ ЛЕДОВИТЫМ ОКЕАНАМИ

Abstract

The interannual variability of the mass transports through the Denmark and Fram Straits, and through the sections separating the Nordic Seas from the Atlantic Ocean and Barents Sea is studied on the base of numerical simulations performed with the use of the Argobased Model for Investigation of the Global Ocean (AMIGO). The model consists of a block for variational interpolation to a regular grid of Argo floats data and a block for model hydrodynamic adjustment of variationally interpolated fields. Additional numerical experiments were carried out in order to study the contribution of the wind forcing to the interannual variability of the transports: the real thermohaline fields corresponding to the particular time period were replaced by climatic ones (1) and by replacing the real wind forcing data with the climatic ones (2). Analysis of the numerical experiments results has shown that the variable wind stress forcing is the key factor determining the interannual variability of the water exchange between Atlantic, Nordic Seas, and Arctic Ocean.
