The problem of the generation of internal tides through the interaction of
surface tides with oceanic bottom topography is re-examined, taking into ac
count the horizontal components of the Earth's rotation. It is shown that p
revious models that have omitted these terms may be readily extended to inc
lude them, and changes in the magnitude and character of the barotropic to
baroclinic conversion are estimated. For semi-diurnal tides the energy conv
ersion is increased, but only by about 2%, However, the character of the wa
ves differs at high latitudes, where the phase and location of the wave ene
rgy may change by as much as 14%. Accordingly, inclusion of these terms is
recommended in future studies with these models. (C) 2000 Elsevier Science
