Oceanweather Wind File Format
The file format for the Oceanweather wind file (*.win) is best described with an example:

The last two arguments of the header is are the starting and end times in yyyymmddhh. The wind data is preceded by a header line with the grid information. iLat and iLong are latitude North and longitude West. DX and DY are the grid spacing in units of degrees. SWLat and SWLon are the coordinates of the south-west grid point. DT is the actual time in yyyymmddhhMM. First the wind velocities in the x-direction are read than the velocities in the y-direction. The wind speeds are written in m/s.
