Detailed instructions for compiling WRF are found in the README file
    located in the ../../WRFV1 directory. Once you have successfully compiled
    WRF, to run the winter cyclone test case, first edit the namelist file 
    namelist_cyclone.input located in the current directory to make any 
    desired changes from the winter cyclone control simulation discussed at 
    http://www.mmm.ucar.edu/wrf/WG7/cases/storm.html
 
    It is recommended that you limit changes to those involving choices
    of physical parameterizations (e.g., mp_physics, bl_pbl_physics, 
    cu_physics) found in the record &namelist_04. The user may wish to change 
    the duration of the simulation in &namelist_05, which is currently set    
    to the maximum amount of time for which necessary input data is provided, 
    or the frequency of outputs in &namelist_02 (time_step_count_output, 
    frames_per_outfile). However, here the user needs to be aware that 
    changes to one namelist variable may necessitate compensatory changes to 
    other namelist variables. The user should NOT change grid dimension 
    variables (e.g., e_we, e_sn, e_vert in &namelist_02; dx, dy, ztop in 
    &namelist_03) since these variables are already set for the input data 
    files (named real_input_em.d01.yyyy-mm-dd_hh:mm:ss). 
 
    Once namelist_cyclone.input has been edited, the file must be saved or 
    renamed to namelist.input in order to run the winter cyclone simulation. 
    To run WRF, first type real.exe to generate the initial and boundary 
    condition files, wrfinput and wrfbdy. After these files have been 
    generated, type wrf.exe to run the model. In a successful simulation, the 
    current (default) setup specified in namelist_tc.input produces an output 
    file (wrfout_01_000000) that is approximately 97 megabytes and contains 
    model output data at 6 hour intervals (t = 0, 6, 12, 18, and 24 h).

    Some of the plots from the control simulation displayed at 
    http://www.mmm.ucar.edu/wrf/WG7/cases/storm.html were produced using the 
    RIP (Read, Interpolate, and Plot) software package available for the 
    Pennsylvania State University/NCAR Mesoscale Model Version 3 (MM5). For 
    users familar with RIP, two files (winter_cyclone_24hprcp.in, and 
    winter_cyclone_6hprcp.in) have been provided to create similar plots 
    using the RIP executable (rip). WRF users of RIP are advised that a 
    special version of the RIP preprocessing program (ripdp4wrf) needs to be 
    successfully executed on the model output data (wrfout_01_000000) first. 
    The fortran program ripdp4wrf.F, along with instructions for compiling and
    running, can be downloaded from ?http://www.mmm.ucar.edu/wrf/WG7/cases? 
    After ripdp4wrf has been successfully executed, WRF users may use the RIP 
    executable (rip) along with the input files winter_cyclone_24hprcp.in, or
    winter_cyclone_6hprcp.in to produce plots. The RIP software and 
    instructions (RIP.TAR.gz) for compiling and executing rip may be obtained 
    via anonymous ftp to ftp.ucar.edu and cd'ing to the directory 
    /mesouser/MM5V3. However, for our application, rip is run on output from 
    ripdp4wf (which is the analog of output from ripdp for MM5 model data).
