Re: Hyperthreading vs performance

Hi Meteo, i have i7 4770k, with HT enabled (Fedora 20), but for WRF-EMS 3.4 i use in ems.cshrc setenv NCPUS 1 setenv CORES 4 in ems.profile NCPUS=1 ; export NCPUS CORES=4 ; export CORES in run_ncpus.conf REAL_NODECPUS = local:4 WRFM_NODECPUS = local:4 I think it is the same thing as having the HT of...

Re: Temperature 2m ​​above the ground too cold

SNOW and SNOWH are not present as output parameters Where? In gribs or in wrfout fields? in wrfout fields they should be if I recall correctly. In gribs snodsfc is SNOWH field. In grib2 fields, after conversion with grib2ctl.pl i don't see SNOW or SNOWH, only snodsfc, For wrfinput_d01 or wrfinput_d...

Re: Temperature 2m ​​above the ground too cold

SNOW and SNOWH are not present as output parameters in wrf do you think is correct to make this change ncap2 -O -s 'where (SNOW < 10) SNOW=0' /home/andrea/wrfems/runs/arw/wrfinput_d01 /home/andrea/wrfems/runs/arw/wrfinput_d01 ncap2 -O -s 'where (SNOWH < 0.1) SNOWH=0' /home/andrea/wrfems/runs/arw/wrf...

Re: Temperature 2m ​​above the ground too cold

Gippox, I can see that you have data in weasdsfc variable. This should be amount of snowfall like apcpsfc is for total precipitation. I think. But my weasdsfc is always empty. Do you know why? I use UPP 2.1 compiled myself, like you do? BTW colors are very easy to control in GrADS, which part you d...

Re: Temperature 2m ​​above the ground too cold

Italian is OK, I can understand little bit, but not enough to directly help. However, google translation is sometimes so bad that I can't understand it either :) :lol: Dominic i answer you in English, so Meteoadriatic, can also understand, even if i use google translation a little bit to translate ...

Re: Temperature 2m ​​above the ground too cold

Gippox, your wrf is very nice and powerful, why do not you also for the central-ARW? PS: You should only change the temperature range of 2 meters and is gorgeous;-), my humble opinion. Thank you Dominic :) , maybe in the future i also put the maps for the South of Italy, i would like to have the wh...

Re: Temperature 2m ​​above the ground too cold

Another thing, I don't find snow cover maps on your site. Can you post an example of snow cover over your domain? It could be the reason if you have snow on the ground where is shouldn't be, but in that case I think that maximum temperatures will be more bised than minimum. Hi Meteo, for now on my ...

Re: Temperature 2m ​​above the ground too cold

Yes your run is much colder on some places, for example over peninsula Istria. I don't see anything in your namelist that could make such difference. However, do you use WRF 3.5 or older? I would first try to make a run without wrfda, just to see if this makes important difference. If run without w...

Re: Temperature 2m ​​above the ground too cold

Ok i changed to Modis land use. The result is improved in conditions of low humidity, but now for example that it is raining slightly and the humidity is 100% the average temperature is lower than 2-3° C. In fact, even looking at the site of Meteoadriatic the same run 06Z to 18Z02JAN2014 the tempera...

Re: Temperature 2m ​​above the ground too cold

Ok thank you Meteo, i will try to change the land use with MODIS, the next run i'm trying ra_lw_physics 05 ra_sw_physics. Hopefully i will try to edit the VEGPARM.TBL file like you said, raising the values ​​of emissivity EMISSIMIN, EMISSMAX. I'll see if the temperatures predicted improve. Vegetatio...
