Barotropic cyclone

Barotropic cyclones are those where isotherms are parallel to height lines on a map at a constant pressure surface, or at the surface, parallel to isobars. Tropical cyclones and cut off cyclones (occluded and formerly occluded cyclones) both qualify as barotropic, though due to differences in their vertical wind structure and temperature profiles, cutoffs are referred to as "barotropically cold" and tropical cyclones are called "barotropically warm".
