Аннотация
The results of numerical experiments on the sensitivity of the INMCM48 Earth System model (Institute of Numerical Mathematics, Russian Academy of Science (INM RAS)) to the various parameterizations of convection induced by the formation of a new ice are presented and analyzed. It is shown that the response in temperature and salinity is observed not only directly under the ice, but in ocean subpolar regions as well, which is especially pronounced in the North Atlantic. An effective parameterization is proposed which significantly reduces the estimation error of the surface salinity in the AO with no formation of the trends of the near-bottom salinity fields, in contrast with the well-known parameterization (Nguyen, Menemenlis and Kwok, 2009).
