[Wrf-users] Unrealistic temperature on WRF simulation output:

[Eric Altshuler]

Hello Morris,

Actually the surface temperature looks fairly normal for this region. SST values are 80-85 F which is typical for the oceans around Southeast Asia. Over land, the highest temperatures (>90 F) are over low-lying parts of the Indochina peninsula at the hottest part of the day (06Z), while maximum temperatures over elevated areas in Malaysia and Indonesia are much cooler (70-75 F) and minimum temps range from 60-65 F over higher areas to 75-80 F over lowland areas. These results are in general agreement with climatology for the Southeast Asia region.

Best regards,

Subject: [Wrf-users] Unrealistic temperature on WRF simulation output:




Dear Sir/Madam, 

I am having problems with my WRF simulations output results. The surface temperature from the WRF outputs seem so high for the location of study. For instance, 69-75 F was the least temperature observed on settlement areas and about 84-90 F on water body. 
I am a new user and I'm finding it difficult correcting this error. The attached files are the output results displayed using NCL script (plot_Surface.ncl), namelist.wps, namelist.input for your perusal. 
I used Global FNL 6hourly and 1x1 degrees analysis as the input data. 

Also, I would like to ask these following questions; 
(1) what parameters on WPS and WRF control the output temperature and where can these parameters be edited to better reflect your location of study? 
(2) where on WPS and WRF could one modify the landuse type and /or soil parameters to reflect your location/region of study? 

I need need assistance desperately.
