摘要：

A baroclinic, 3-D model is described. It is adapted to thc Barents Sea and includes thermodynamics and atmospheric input. The freezing and melting of ice is allowed for in thc model. Thc main task of thc study is to look at thc development of thc ice cover, thc vertical mixing. and thc vertical and horizontal density gradients. Despite simple approximations in the air temperature input. realistic ice-cover is produced in thc model area during simulation of a "freezing period" (winter). This intermediate result is briefly discussed and also forms the start of a "melting period" simulation (spring/summer). Atmospheric input data (wind, air pressure, and heat flux) from the spring and summer 1983 is used, and details about vertical mixing. temperature, and salinity are discussed. The simulation results demonstrate the temporal variation of the thermocline depth, the variation of thc ice cover, and the horizontal changes of density. Thc conclusion is that despite often simplified input, the model seems to produce a physical picture characteristic of the Barents Sea.
