[ncl-talk] CAPE and CIN calculation

[Bill Ladwig]

The bug is due to incorrect units for PSFC, which should be in hPa.  So, in
the WRFUserARW.ncl script, for the line you mentioned above:

cape = wrf_cape_3d( P, tk, QV, z, HGT, PSFC, True )

should be:

cape = wrf_cape_3d( P, tk, QV, z, HGT, PSFC/100., True )

See Dave's reply for how to view the wrf_cape_3d C/Fortran source code.
