The Weather Research and Forecasting (WRF) Model is a next-generation mesoscale numerical weather prediction system designed for both atmospheric research and operational forecasting applications. It features two dynamical cores, a data assimilation system, and a software architecture supporting parallel computation and system extensibility. – WRF

I. Prerequisites

A. Install perl, mpi, hdf5, netcdf using the package manager

### What? You wanna install WRF on Windows or macOS???? Why are you hating yourself???

##### If you want compile wrf with intel compiler, you should compile and install hdf5, netcdf and netcdf-fortran mannually as below.

B. Compiling hdf5 & netcdf manually

  • hdf5. Download hdf5 and unpack it to hdf5. Current versions are 1.8.20 and 1.10.1, and we choose the latest version.

module load mpi/mpich-x86_64
export HDF5=/usr/local
./configure --prefix=$HDF5 --enable-fortran=yes --enable-hl --enable-optimization=high --enable-parallel CFLAGS='-fPIC'
make && make check && make install
  • netcdf and netcdf-fortran. Download netcdf and netcdf-fortran, and unpack them. Current version is 4.6.0 for netcdf and 4.4.4 for netcdf-fortran till 5/2/2018.

cd netcdf-4.6.0
#### XXX: If you install hdf5 into a non-standard location, remember to add $HDF5/include to $C_INCLUDE_PATH and $HDF4/lib to $LD_LIBRARY_PATH
export NETCDF=/usr/local
./configure --prefix=$NETCDF --enable-dot --enable-fsync --enable-cdf5 LDFLAGS="-L$HDF5/lib" CPPFLAGS="-I$HDF5/include"
make -j4 && make check && make install
cd ../
cd netcdf-fortran-4.4.4
./configure --prefix=/usr/local --enable-dot LDFLAGS="-L$HDF5/lib -L$NETCDF/lib" CPPFLAGS="-I$HDF5/include -I$NETCDF/include"
ake -j4 && make check && make install

II. Compiling WRF

  1. The latest release of WRF is 3.9.1.1 till now 5/2/2018. Download the WRF source code, and extract it to WRF
  2. Configure WRF

module load mpi/mpich-x86_64
#### If you didn't set NETCDF and HDF5 environment variables, set them to where they are installed.
#export NETCDF=/usr/local
#export HDF5=/usr/local
export WRFIO_NCD_LARGE_FILE_SUPPORT=1
#### run ./configure
./configure
After run `./configure`, it will let us to choose which option to compile. Here we choose `35`, which `wrf` will use `mpi` and `openmp`.

#### nesting option: 1=basic just ok
Compile for nesting? (1=basic, 2=preset moves, 3=vortex following) [default 1]: 1
......
#### configure done
  1. After configure finished, we then can run ./compile wrf to compile WRF. Note that if one choose INTEL compiler with mpi and openmp, one might need to edit configure.wrf by changing -openmp to -qopenmp, or it will fail to compile.

./compile wrf
./compile em_real
#./compile em_fire
#./compile convert_em
When compilation is done, you will find `wrf.exe` and other executable files under the `main` directory.

III. Runnig Test of WRF

The test directory is WRF/run, and you can run a test job on a cluster… -_-…
