Describe the generation of sea-wave by wind

A wind-generated wave can be predicted based on two parameters: wind speed at 10 m above sea level and wind duration, which must blow over long periods of time to be considered fully developed. The significant wave height and peak frequency can then be predicted for a certain fetch length. See more In fluid dynamics, a wind wave, water wave, or wind-generated water wave, is a surface wave that occurs on the free surface of bodies of water as a result of the wind blowing over the water's surface. The contact distance in the See more Three different types of wind waves develop over time: • Capillary waves, or ripples, dominated by surface tension effects. • Gravity waves, dominated by gravitational and inertial forces. See more As waves travel from deep to shallow water, their shape changes (wave height increases, speed decreases, and length decreases as wave orbits become asymmetrical). This … See more Wind waves are mechanical waves that propagate along the interface between water and air; the restoring force is provided by gravity, … See more The great majority of large breakers seen at a beach result from distant winds. Five factors influence the formation of the flow structures in wind waves: 1. See more Ocean waves can be classified based on: the disturbing force that creates them; the extent to which the disturbing force continues to influence them after formation; the … See more Some waves undergo a phenomenon called "breaking". A breaking wave is one whose base can no longer support its top, causing it to collapse. A wave breaks when it runs into shallow water, or when two wave systems oppose and combine forces. When the … See more WebNov 25, 1994 · Spaceborne synthetic aperture radar can detect storm footprints on the sea. Coastal weather radar from Cape Hatteras provides evidence that the echo-free hole at the footprint core is the result of wave damping by rain. The increased radar cross section of the sea surrounding the echo-free hole results from the divergence of the precipitation ...
