    Relative vorticity as WRF output

    Hi, everyone First of all I hope that you are well, continuing with the post I want to ask if there is a way to obtain the relative vorticity as output in the netcdf file from WRF, I have read that the only one that is obtainable is the absolute vorticity. I have been using these formula to...

    Gust speed lower than mean wind speed in NMM output

    Hi all, I found that in the output of the NAM models by NCEP the gust speed is often significantly lower than the mean wind speed. NAM uses the WRF-NMM dynamical core. In terms of the grib output, I found GUSTS < sqrt(UGRD**2 + VGRD**2) I did not yet check if this is also the case for HRRR...

    Upscaling Wrfout file for calculation of verification metrics

    Hi, My wrfout files are at 10km, 3.3km and 1.1km. My task is to verify the performance of the different domains with MSWEP gridded satellite data which is 0.1 degrees for different size areas. Therefore, I want to upscale (resample) all domains to the resolution of the MSWEP data. My wrfout...

    showing new parameter in ncview

    Dear All, I am trying to simulate a dust storm and analyse it by Dust load. I can see the results in ncview, while, there are 5 of them based on their size category. which their names are DUSTLOAD_1, DUSTLOAD_2,..., DUSTLOAD_5 I want to define a new parameter named total dust load which is the...
