如何改变模式模拟区域

用户可能会根据业务需求，或根据计算资源调整预报区域， 请按照以下的步骤进行修改 ：

1. 生成新的地形文件， 分别拷入：

   $ mv geo_em.d01.nc.d1 nwprod/rap.v4.0.12/fix/rap_geo_em.d01.nc
   
   $ mv geo_em.d01.nc.d2 nwprod/hrrr.v3.0.8/fix/conus/hrrr_geo_em.d01.nc
   $ cp nwprod/hrrr.v3.0.8/fix/conus/hrrr_geo_em.d01.nc nwprod/hrrr.v3.0.8/ncl/ncl/geo_em.d01.nc
   

2. 修改 namelist

   $ edit nwprod/rap.v4.0.12/parm/rap_namelist.wps
   $ edit nwprod/rap.v4.0.12/parm/rap_wrf.nl
   $ edit nwprod/rap.v4.0.12/parm/rap_wrfbc.nl
   
   $ edit nwprod/hrrr.v3.0.8/parm/conus/hrrr_namelist.wps
   $ edit nwprod/hrrr.v3.0.8/parm/conus/hrrr_real.nl
   $ edit nwprod/hrrr.v3.0.8/parm/conus/hrrr_wrf.nl
   $ edit nwprod/hrrr.v3.0.8/parm/conus/hrrr_wrfpre.nl
   $ edit nwprod/hrrr.v3.0.8/parm/conus/hrrr_wrfpre_norad.nl
   

3. 修改如下脚本，寻找 targetsize, 替换修改后的 wrfout 的 size：

   $ exrap_analysis.sh.ecf:    targetsize=xxxxxxx
   $ exrap_analysis_pcyc.sh.ecf:      targetsize=xxxxxxxx
   $ exrap_post.sh.ecf:  targetsize=xxxxxx
   
   $ exhrrr_analysis.sh.ecf:targetsize=xxxxxx
   $ exhrrr_post.sh.ecf:targetsize=xxxxxx
   $ exhrrr_prep_ref2tten.sh.ecf:targetsize=xxxxxx
   

4. 修改 exrap_post.sh.ecf, 参见：wgrib2文档.

   $ edit nwprod/rap.v4.0.12/scripts/exrap_post.sh.ecf
   ...
   Modify:
   export grid_specs_130="lambert:105:30.000000:60.000000 76.251953:525:13000.000000 13.022026:462:13000.000000"
   

5. 重新生成 enkf 文件

6. 删除原来的初始条件和边界条件

   $ rm nwges/prod/rap/rapbc/*
   $ rm nwges/prod/rap/rapges/*
   $ rm nwges/prod/rap/rapges_pcyc/*
   
   $ rm /nwges/prod/hrrr/hrrrges_sfc/conus/*
