Problem on Potential Vorticity (PVU) and Surface Evaporation

Post by meteo60 » Tue Dec 22, 2015 4:23 pm

Hi everybody
I'm testing new UEMS 15.51 and I have some problems with PVU. In CTL there is line
HGT1p5e+06pv 0,109,1.5 0,3,5 ** PV=1.5 (Km^2/kg/s) surface Geopotential Height [gpm]

on old EMS there was hgt1p5pv
So Grads can't display HGT1p5e+06pv ; is the "+" cause the bug?

Other problem on potential evaporation. On old EMS I have pevapsfc, on UEMS I have only EVPsfc but in emsupp_ctrl.parm there is:
(ACM_EVP_ON_SURFACE) SCAL=(4.0) ! Accumulated Evaporation at Surface (kg m-2) FNUM=(047)
L=(10000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000)
(ACM_PEVAP_ON_SURFACE) SCAL=(4.0) ! Accumulated Potential Evaporation at Surface (kg m-2) FNUM=(137)
L=(10000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000 00000)

So I don't understand why in the CTL I have not PEVAPSFC?
