One seamount locates at (0km, -19km).

The dominant tendency is for the vortex to circumnavigate the vortex cyclonically, and for the bulk of this trajectory to occur with minimal actual contact of hte Meddy with the seamount. This characteristic of nearly all of hte experiments that we have conducted and can be understand by appealing to the concept of image vortices inside the seamount and their kinematic effect on the imping Meddy.

There is considerable distortion of the core around the seamount at the vortex effectively breaks. The organizing tendencies of the like-signed anticyclonic vorticity however holds together clumps of the initial vortex, permitting two groupings of like-signed vorticity to exit the seamount. These clumps, each contained within lengths comparable to a deformation radius, form the nuclei from which the subsequent vortices emerge. Such collision is common.

One seamount locates at (0km,42km).
The vortex stagnates in the near neighborhood of the cylinder boundary, where it spends quite some time. It is held together by the integrity of its core but undergoes constant distortion due to the shearing effects of the mean flow and the vortex images. Eventually the core becomes too weak to maintain its position against mean advection and a considerably reduced core is swept anticyclonically about the seamount. It has a little more than hald its pre-collision point vortex population at the end of the experiement.
