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 tropical cyclone (Barry 2001) test case, first edit the 
    namelist file namelist_tc.input located in the current directory to make 
    any desired changes from the tropical cyclone control simulation discussed
    at http://www.mmm.ucar.edu/wrf/WG7/cases/barry.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_tc.input has been edited, the file must be saved or renamed
    to namelist.input in order to run the tropical 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 605 megabytes and contains model
    output data at 3 hour intervals (t = 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 
    30, 33, 36, 39, 42, 45, and 48 h). 

    Some of the plots from the control simulation displayed at 
    http://www.mmm.ucar.edu/wrf/WG7/cases/barry.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, a file (tropical_cyclone_3hprcp.in) has 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 file tropical_cyclone_3hprcp.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).
