Swell (ocean)

With swell waves are called that are not of current events such as wind, etc. horizontal (see wind sea ). The wind abates after yet expiring sea is called the swell or swell (English swell ). This often comes from other, sometimes distant marine regions. Sea state is the generic term for swell and wind sea. When the swell leakage, the wave height decreases and the wavelength to be. At shallows or a coast the swell may be deemed Grundsee or surf pile up again to high breakers. As reflected not only the current wind situation because of the swell in the sea, it can come to the superposition of waves, called a cross sea.

The strength of the swell is not only dependent on the wind speed, but also very much on the wind pitch length, the distance from the open sea wind direction at the site. The longer the wind pitch length, the higher the swell builds. For example, the swell on the North Sea at West Wind is much stronger than with the east wind, because in the former case, the waves can build up over the entire length of the North Atlantic. The wind Effective length is also called himself swell, sometimes even after the English term as Fetch.
