minloc() and maxloc() in GrADS

Hallo all, how to "right" use minloc() function in GrADS to find grid coordinates of, for example, pressure minimum? something like this is working, but not returning longitude coordinates of pressure minimum :( : 'd minloc(minloc(prmslmsl,lon=7,lon=24),lat=45.5,lat=53.5)' Thanks for all comments......

Re: WRF EMS Cloud's to low in %

I am using something like this:

in GrADS:


'cldL=mean(tcdcprs*100,lev=1013,lev=760)'
'cldM=mean(tcdcprs*100,lev=750,lev=510)'
'cldH=mean(tcdcprs*100,lev=500,lev=200)'

'cldT=cldH+cldM+cldL'


where:
cldT = total cloud cover
cldL = low clouds
cldM = middle clouds
cldH = high clouds

Re: WRF EMS Cloud's to low in %

Hallo, In V3.0 are after postprocessing in grib1 file clouds (TCDCprs) <0..100> In V3.1(26) there are clouds (TCDCprs) <0..1> I changed in grads scripts for V3.1 > 'd TCDCprs*100' and there is the same result as in V3.0 'd TCDCprs' But in V3.1 I have all times lower quantity of clouds than in V3.0 :...
