WRF¶
简介¶
WRF(Weather Research and Forecasting Model)模式是有美国环境预报中心(NCEP), 美国国家大气研究中心（NCAR）以及多个大学、研究所和业务部门联合研发的一种统一的中尺度天气预报模式。 WRF模式适用范围很广，从中小尺度到全球尺度的数值预报和模拟都有广泛的应用。
WPS是预处理WRF运行数据的工具。

ARM上运行WRF¶
由于WRF运行数据需要复杂的文件依赖关系，可先拷贝WRF目录中必要的文件到本地
cd ~/data
cd WRF
mkdir WRF-4.3.1 && cd WRF-4.3.1
cp -r /lustre/opt/contribute/cascadelake/wrf_cmaq/packet_1/WRF-master/run/* ./
拷贝WPS生成的met文件到WRF-4.3.1目录
cp -r ~/data/WRF/WPS-4.3.1/met_em.d* ./
namelist.input文件内容设置如下，参数需要与wps的namelist.wps参数一致：
