Re: Precipitation without precipitation type

Hello, I asked the same question to Robert, his response was: the categorical precipitation type is computed in relation to the instantanious precipitation. This may differ from the accumulated period precipitation. E.g. there was precipitation during the accumulation period, but at the exact timest...

Re: Precipitation without precipitation type

Here is my model configuration: ****************************************************************************** Domain & Run Information Domain Type : Limited Area Primary Time Step : Adaptive Step to Output Time : Yes Grid dimensions (NX x NY) : 560 x 450 Vertical Layers (NZ) : 45 Grid Spacing : 7.0...

Re: Precipitation without precipitation type

So I went on to try this solution. First I added the following parts in emsup_cntrl.parm (by the way, it seems the parameters were renamed between your version of UEMS and the latest one): # from: data/tables/post/grib2/emsupp_cntrl.HYBRID_ALL (RWMR_ON_HYBRID_LVL) SCAL=(-4.0) ! Rain Water on Hybrid ...

Re: Precipitation without precipitation type

Hello, thank you for your help! In my original emsupp_cntrl.parm file I cannot find the variables you mentioned, I only find the variables on pressure surface like for example: (RWMR_ON_ISOBARIC_SFC) SCAL=(-4.0) ! Rain Mixing Ratio on Pressure Surface (kg kg-1) FNUM=(183) L=(00000 00000 00000 00000 ...

Precipitation without precipitation type

Hello, I am running the latest UEMS with a domain over Europe. I am postprocessing these files via GrADS and I am running into strange errors in my output files. In my emsupp_cntrl.parm file, I am extracting the following variables: (BUCKET_APCP_ON_SURFACE) SCAL=(4.0) ! Period Accumulated Total Prec...

Re: Wind speed overestimation for domain over Canary Islands

Just a short update on this case. I increased the domain size, and I could finally solve this problem. In a slightly larger domain with 158 x 120 points with 4km resolution the error still persisted. After changing the domain resolution to 5km due to timings for my real-time forecasts (with the same...

Re: Wind speed overestimation for domain over Canary Islands

Hello, I am just getting back to this topic as I want to improve the forecast quality for my domain. As meteoadriatic pointed out, the domain is probably too small in general. What is the limiting factor in this case - is the covered geographical area too small? Or is the number of points in this do...

Re: Wind speed overestimation for domain over Canary Islands

Maybe this could work, thanks. Unfortunately this data is no longer available on NOMADS, so I will have to check if I can download the files manually and put it in the correct places for WRF to use them. Anyway, thank you for your help!

Best regards,

Jonas

Re: Wind speed overestimation for domain over Canary Islands

Hello, just getting back from vacation and getting back to this topic. Today I could confirm that this was indeed an error in the GFS 0.25 deg Personal Tile files. I have checked with the GFS 0.5 deg full files and GFS 0.5 deg Personal Tiles, and the simulation was running smoothly. I would like to ...

Re: UEMS wind parametrization

Hello, interesting topic - would be great if you could share your results which configuration works best for you and your area. From my experience for domains over Europe there is no clear "winning" configuration pattern available - the best accuracy gains I got was from increasing the resolution (a...
