What Is a Swell in the Ocean?
Ocean swells are characteristically smooth, without the peaks and breakers of a wave. They might appear to be gently rolling across the seascape like watery creatures lumbering peacefully toward an unknown destination, possibly imparting a gentle rocking motion to the vessels they encounter on the journey. They may even possibly leave a boat’s occupants in a temporary state of zero gravity, if their period is short enough and if they are occur in concert with waves.
