All swells are created by wind blowing over the surface of the ocean. As wind blows, waves begin to form. ... When winds blows very strong, for a long time, over vast distances (i.e. storms), the distance between waves becomes longer and the energy driving the waves becomes greater.
So basically water is a polar molicule. So when it comes to the structure, water is able to form many hydrogen bonds and the way the atoms are able to bond together adds to the water's special properties.
