Deep water waves that have the greatest wavelengths and longest periods,
travel the fastest and are the first to arrive in regions distant from the
storm which generated them
Methinks it might be something like this if the wave was generated by a
storm in deep waters (assuming the wave length to be double the depth
available):
The square root of (9.8 m/sec (acceleration due to gravity) X 4,000 m (an
estimate of the average depth of the Atlantic Ocean)) which works out at
roughly 198 meters per second,
Therefore the wave would take about 5.6 hours to travel 4000 km.
