Describe the generation of sea-wave by wind
WebWaves form as a result of the water’s motion, gravitational forces, and winds. The most common waves we see are created by wind. However other waves include those created by gravitational forces (e.g. tidal … WebOcean waves are produced by the wind. The faster the wind, the longer the wind blows, and the bigger the area over which the wind blows, the bigger the waves. In designing ships or offshore structures we wish to …

WebStorm surges and disastrous waves induced by cold air outbreaks, a type of severe weather system, often impact the coastal economic development. Using the Climate Forecast … 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 ...
WebVarious models have recently been developed to describe Arctic coastal erosion. Current process-based models simulate multiple physical processes and combine them interactively to resemble the unique mechanism of Arctic coastal erosion. One limitation of such models is the difficulty of including hydrodynamic forces. The available coastal erosion models … WebSea is a term used to describe the mixture of waves often observed from ships. Seas may include ripples, chop, wind waves, storm waves, and swells. Seas are characterized by waves of differing heights coming from many directions (Fig. 4.7). Swells are waves that have obtained enough energy to travel beyond their generation area or fetch.
