The tides in the Arctic Ocean from a finite element model

摘要: The two main diurnal (i.e., K1 and O1) semidiurnal M2 S2) tidal waves have been computed from a hydrodynamic, finite element, spectral model. spatial resolution of the model varies few kilometers at coastline to 100 km in deepest regions. An optimization open boundary conditions has performed improve solution accuracy. bottom topography used this originally extracted Earth Topography 5-minutes Grid (ETOPO5) corrected various sources data. impact input parameters like friction coefficient, loading effects, parameterisation additional due Arctic ice cover is investigated. elevations are compared set situ observations validated. They also Kowalik Proshutinsky [1993] These comparisons mainly show good agreement between models. Nevertheless, significant differences observed where small wavelength structures produced by topographic trapping energy. velocities associated with presented. potential rate work, dissipation, energy fluxes these velocities. Because uncertainties boundaries, we restricted qualitative analysis equation terms, which appears be consistent previous studies on tides.
