摘要：

Upper ocean convection under narrow ice leads is considered and simulated. The effects associated with the localization of the buoyancy source and with the influence of the Coriolis force are discovered. An explanation is proposed for a mechanism that forms a stably salt-stratified isothermal layer during cold seasons at high latitudes. Observational data are qualitatively consistent with the simulation results. The existing parameterizations of under-ice convection in modern climate models are discussed and their possible defects are indicated.
