A man standing next to large ocean waves at Porto Covo, Portugal Video of large waves from Hurricane Marie along the coast of Newport Beach, California. In fluid dynamics, a wind 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.
Ocean Waves, known in Japan as I Can Hear the Sea (Japanese: 海がきこえる, Hepburn: Umi ga Kikoeru), is a 1993 Japanese anime coming-of-age romantic drama television film directed by Tomomi Mochizuki and written by Keiko Niwa (credited as Kaoru Nakamura) based on the 1990–1992 novel of the same name by Saeko Himuro.
The ocean has a vast amount of energy carried by ocean waves, tides, salinity differences, and ocean temperature differences which can be harnessed to generate electricity. [169] Forms of sustainable marine energy include tidal power, ocean thermal energy and wave power.
Breaking swell waves at Hermosa Beach, California. A swell, also sometimes referred to as ground swell, in the context of an ocean, sea or lake, is a series of mechanical waves that propagate along the interface between water and air under the predominating influence of gravity, and thus are often referred to as surface gravity waves.
The waves themselves are examples of cnoidal waves. Cross sea near Lisbon, Portugal. A cross sea (also referred to as a squared sea or square waves [a]) is a sea state of wind-generated ocean waves that form nonparallel wave systems. Cross seas have a large amount of directional spreading. [1]
An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. [1]
A Kelvin wave is a wave in the ocean, a large lake or the atmosphere that balances the Earth's Coriolis force against a topographic boundary such as a coastline, or a waveguide such as the equator. A feature of a Kelvin wave is that it is non-dispersive , i.e., the phase speed of the wave crests is equal to the group speed of the wave energy ...
The University of Oslo has conducted research into crossing sea state and rogue wave probability during the Prestige accident; nonlinear wind-waves, their modification by tidal currents, and application to Norwegian coastal waters; general analysis of realistic ocean waves; modelling of currents and waves for sea structures and extreme wave ...
