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：

    .. code-block:: bash

        $ 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

#. 修改 :code:`namelist`

    .. code-block:: bash

        $ 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

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

    .. code-block:: bash

        $ 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

#. 修改 :code:`exrap_post.sh.ecf`,  参见：`wgrib2文档 <https://www.cpc.ncep.noaa.gov/products/wesley/wgrib2/new_grid.html>`_.

    .. code-block:: bash

        $ 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"

#. 重新生成 :code:`enkf` 文件


#. 删除原来的初始条件和边界条件

    .. code-block:: bash

        $ rm nwges/prod/rap/rapbc/*
        $ rm nwges/prod/rap/rapges/*
        $ rm nwges/prod/rap/rapges_pcyc/*

        $ rm /nwges/prod/hrrr/hrrrges_sfc/conus/*
