The functions to which you are referring wrf_* were created
by the WRF project (wrfhelp). This email is being forwarded to
wrfhelp@ucar.edu

Good luck

We have compared our results with the University of Wyoming soundings, which uses a similar procedure to calculate CAPE (using the temperature of a parcel from the lowest 500 m of the atmosphere, raised dry adiabatically to the LCL and moist adiabatically thereafter), however the wrf_cape3d procedure produces CAPE values an order of magnitude larger than the U Wyo CAPE values. We have used the exact sounding the U of Wyo have used and tried many other tests to get more reasonable results.
