Miller, A. J., 1986:
Non-divergent planetary oscillations in mid-latitude ocean basins with continental shelves
Journal of Physical Oceanography,
Free oscillations in square, midlatitude basins with continental shelves and planetary vorticity gradients are numerically
computed using the nondivergent shallow-water equations. The topography may rend a planetary mode into a family of
basinwide modes, each comparable to the flat-bottom counterpart in frequency and midbasin structure. This phenomenon
can be interpreted in terms of coupled planetary wave-shelf wave oscillations. The mechanism provides an alternative to
strong dissipation in explaining broadbanded planetary-wave signals signals observed in tide guage records.
