Support,

COMET's NAWIPS was recently updated and some of the meteorologist visiting
noticed an error in the default cross-section plotting input to Potential
Vorticity.  On our system the file to be changed is at the following
location:

/pub/nawips/comet/garp/fdf/xsscalar/default/general/PotVort_Ks-1P-1

and the line to change is:

function                = PVOR ( TMPK, WND )

it should read:

function                = PVOR ( THTA, WND )


In other words Potential Vorticity should use potential temperature,
not temperature.

Kevin
