Numerical analysis of the circulation variability in the Zadar channel area (east Adriatic)
Three numerical hydrodynamic models, ROMS, POM and MIKE 3 FM, were used to simulate circulation variability in the middle Adriatic coastal area. ROMS and POM models were used to perform a year-long simulation of the Adriatic circulation with the spatial resolution of approximately 2 km. Temperature, salinity and sea level fields, obtained by the ROMS model, were used for the initial and boundary conditions in the MIKE 3 FM local domain covering the channel area off Zadar. A similar area was covered with the POM local domain nested within the shelf and Adriatic-scale POM models using threedimensional velocity, temperature and salinity fields, as well as two-dimensional sea level fields from coarser resolution grids. Current fields obtained by both modelling systems are in agreement with the ADCP measurements performed in the area of the local models. During winter northwestward currents dominate in the surface layer, while in the lower layers of the channel topographically controlled gyres can be observed. Both measurements and numerical simulations indicate current reversal to southeastern direction in the coastal area off Zadar during summer.
