Abstract
    A modelling system for the Baltic Sea has been developed based on the use of a data assimilation system (DAS), which is coupled with the Baltic Environmental Database and with a three-dimensional baroclinic prognostic model. The basic model equations and the development of a user-friendly interface are described. In this paper the model is applied in studies of the basic hydrodynamic features of the Baltic Sea e.g. the mean circulation and its stability, water exchange and related features, the horizontal and vertical structure of salinity, sea-level variations and upwellings, and sea temperature. A chemical model is used to investigate the sediment-water interface processes. A nested grid system is utilised throughout the simulations, in which a horizontal resolution of one nautical mile is used in the area of interest.
