Математическое моделирование процессов в атмосфере и гидросфере

In this work we examine the effect of the Arctic cold mass inclusion on the general circulation simulated by World Ocean Circulation model. The model was forced by seasonally-varying climatological boundary conditions of temperature, salinity, and wind stress. Temperature (T) and salinity (S) were damped towards the climatological values of Levitus (1982) with uniform restoring time-scales of 30 days for T and 50 days for S. The wind stress climatology used was that of Hellerman and Rosenstein (1983). The model bathymetry represents a smoothed version of the real World Ocean bottom topography. The model grid spacing is 3.75$^0$ longitude by 4.5$^0$ latitude with unequally spaced vertical levels. The first numerical experiment was carried out for model domain which had a solid wall boundary between Arctic and Atlantic oceans at 73$^0$N. The ocean model was integrated over 1000 years.

In next experiment we used a transitional zone or buffer zone northward from 62$^0$N in Atlantic ocean. We applied here the relaxation technique towards Levitus annual climatology. It helped us to introduce a cold bottom water while upper ocean kept varying seasonally according to surface fluxes. In third experiment the model had a global coverage of the World Ocean including Arctic basin. Some interesting changes in circulation pattern of surface and deep water are discussed in report.
