A diagnosis of vorticity fields associated with an explosively-developing winter cyclone over the southeastern United StatesA diagnosis of absolute (ABS) and potential (POV) vorticity is studied, both calculated in isobaric coordinates, associated with a cyclone that developed explosively over the southeastern United States from January 20-21, 1979. Comparison of isobaric representations of ABS and POV fields relative to an explosively developing cyclone shows that in a number of ways the two vorticity fields exhibited similar relationships to the cyclone. As the cyclone developed, it propagated cyclonically around middle and upper tropospheric ABS and POV maxima, with each being located upstream from the cyclone.
