This paper describes an investigation aimed at modeling of a circulation of the Atlantic Water in the Arctic based on the improved parameterization of the temperature and salinity advections in the numerical model.

The QUICKEST advection scheme reduces over- and undershooting as well as instabilities found within the original scheme used for the ocean modeling. The employed schemes allow considering smaller and more reasonable mixing coefficients and sharper gradients, which lead to an improved representation of the circulation. The numerical coupled ice-ocean model has been favorably verified against observations taken during 1948--2003.
