All rights !/ reserved. WAVEWATCH III is a trademark of the NWS. !/ No unauthorized use without permission. !/ ! 1. Purpose : ! ! Generation of initial conditions for a "cold start" of ! WAVEWATCH III. ! ! 2. Method : ! ! General model information os obtained from the model definition ! file using W3IOGR. The type of the initial field is read ! from the input file WW3_strt.inp (NDSI). Three types of initial ! conditions are available. ! 1) Gaussian distribution in longitude, latitude and frequency, ! cos power in directions. Can default to single spectral ! bin. ! 2) Predefined JONSWAP spectrum, Gaussian height distribution ! in space. ! 3) Fetch-limited JONSWAP spectrum based on the actual wind ! speed. To avoid the need of reading a wind field, the ! restart file is a "dummy", and the actual initial field ! is constructed in the initialization routine W3INIT. ! 4) User defined spectrum throughout the model. ! 5) Starting from rest. ! The initial conditions are written to the restart.WW3 using the ! subroutine W3IORS. Note that the name of the restart file is set ! in W3IORS. ! ! 3. Parameters : ! ! Local parameters. ! ---------------------------------------------------------------- ! NDSI Int. Input unit number ("ww3_strt.inp"). ! ITYPE Int. Type of field (see section 2). ! FP,SIP Real Peak frequency (Hz) and spread. \ ! XM,SIX Real Id. X (degr.). | ! YM,SIY Real Id. Y (degr.). | ITYPE = 1 ! HMAX Real Maximum wave height. | ! NCOS Real Cosine power in dir. distr. | !

Remarks : ! ! - While reading the restart file W3IORS will recognize the ! need for checking the time, as the restart file contains ! information on the origine of the file ("cold" or "hot"). ! - User input for x-wise gaussian spread control, SIX, is ! now available again (option for SIX.NE.SIY available.) ! If user desires a distribution that is circular in real ! distances, user should input a negative number for SIX. ! ! 8.
