Numerical simulations of the collision between deep topographically-steered
anticyclonic eddies and seamounts are described. The simulations are based
on a two-layer intermediate length-scale model which filters out barotropi
c processes and focuses on the sub-inertial baroclinic dynamics within the
context of allowing finite-amplitude height variations in the deep cold edd
ies and a background topographic vorticity gradient. (C) 2001 Editions scie
