500 MB ABSOLUTE VORTICITY
LAYER RELATIVE HUMIDITY /0.44-1.00 SIGMA LEVEL/
850 MB VERTICAL VELOCITY
700 MB VERTICAL VELOCITY
500 MB VERTICAL VELOCITY
THESE PRODUCTS WILL BE AVAILABLE ON AWIPS/NOAAPORT DAILY FROM THE
0000...0600...1200...AND 1800 UTC GFS MODEL RUNS. SEE TABLE 2
FOR THE SPECIFIC LIST OF NEW WORLD METEOROLOGICAL ORGANIZATION
