In the context of a two-layer quasi-geostrophic model on an f-plane, the problem of a self-moving compensated baroclinic vortex (heton) incident on an isolated axially symmetric submerged obstacle of small height is considered. The method of contour dynamics is used to study the characteristic features of the vortex field in the vicinity of the obstacle, depending on the vertical structure of the heton, the height and horizontal sizes of the obstacle, and also the velocity of the background flow.
