What is the difference between whitecap and swell

Answers

Whitecap and swell are the two types of waves which are generated by moving over of water.

What is whitecap and swell?

Waves are normally generated by the wind moving over water surface. They indicate the speed of the wind in the area. Swell is the wave which usually with smooth tops and that have moved beyond the area where they were first generated.

Height of waves varies over time. The wave height is calculated statistically as the average height of the highest one-third of the waves that is experienced over time. Swell waves are the regular, longer period waves which are generated by distant weather systems. They may travel over thousands of kilometers distance. A whitecap is a wave formed when the narrow crests of a wave are blown off by the winds. This creates a mixture of air and water.
