我也想问这个问题，请问你解决了吗？

Using UPP for creating grib1 data from wrfout files to use in ungrib


UPP

Use UPP to process the wrfout* output from your model run to get grib1 files with required fields.  Fields are contained within the new wrf_cntrl.parm file.

The new wrf_cntrl.parm can be downloaded from the UPP FAQs page (last FAQ):
http://www.dtcenter.org/upp/users/overview/upp_faqs.php

Run UPP for grib1 output as normal for grib1 format (*Use new wrf_cntrl.parm file)

wrf_cntrl.parm:  outputs 3 different “grids” or files for each forecast hour:  
WRFTWO* -- 2-d fields, soil, etc
WRFPRS*   -- Pressure level fields
WRFNAT*  -- Native model level fields



Email the UPP Help Desk for questions/problems running UPP: upp-help@ucar.edu
More information on UPP can be found at: http://www.dtcenter.org/upp/users/




WPS – ungrib

Run the UPP grib1 output files through ungrib use as input for the new WRF run.  Requires running ungrib twice with two different Vtables and two prefixes for the ungrib/metgrid.  First for WRFTWO* and second for WRFPRS*


WRFTWO*

>> ln   -sf   ungrib/Variable_Tables/Vtable.ARW.UPP     Vtable
>> ./link_grib.csh    /path-to-upp-output/WRFTWO*    .

Edit the &ungrib section of the namelist.wps to prefix ‘TWO’

&ungrib
out_format = 'WPS',
prefix = 'TWO',

>> ./ungrib.exe

WRFPRS*

>> rm   Vtable   GRIB*
>> ln   -sf   ungrib/Variable_Tables/Vtable.ARWp.UPP     Vtable
>> ./link_grib.csh    /path-to-upp-output/WRFPRS*     .

Edit the &ungrib section of the namelist.wps to prefix ‘PRS’

&ungrib
out_format = 'WPS',
prefix = 'PRS',

        >>  ./ungrib.exe




WPS – metrid

Run metgrid of the two sets of ungribbed data TWO* and PRS*

Edit &metgrid section of namelist.wps to include the two prefixes

&metgrid
fg_name = 'TWO','PRS'
io_form_metgrid = 2,
/

>> ./metgrid.exe

这是我当时记得笔记，你试一下

什么原因啊

爱地理不爱物理

以该wrfout时刻作为起始点运行wrf生成wrfinput和wrfbdy，然后更新这个wrfbdy（wrfda中有关于更新侧边界条件的步骤），wrfout重命名作为新的wrfinput

不知道，现在都不搞upp了
