Knowing the wind sampling average is important, as the value of a one-minute sustained wind is typically 14% greater than a ten-minute sustained wind. [16] A short burst of high speed wind is termed a wind gust ; one technical definition of a wind gust is: the maxima that exceed the lowest wind speed measured during a ten-minute time interval ...
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 currents are instrumental in determining the climate in many regions around the world. While little is known about the effects of removing ocean current energy, the impacts of removing current energy on the farfield environment may be a significant environmental concern. The typical turbine issues with blade strike, entanglement of marine ...
When it comes to wind energy, there's a lot of hot air blowing around. Proponents and opponents alike are guilty of forming opinions without evidence, and energy analysis can often be more mystery ...
Small-scale wind power is the name given to wind generation systems with the capacity to produce up to 50 kW of electrical power. [104] Isolated communities, that may otherwise rely on diesel generators, may use wind turbines as an alternative.
Wind-driven ocean gyres are asymmetrical, with stronger flows on their western boundary and weaker flows throughout their interior. The weak interior flow that is typical over most of the gyre is a result of the conservation of potential vorticity.
Wind wave systems influence oceanic heat exchange, the condition of the sea surface, and can alter ocean currents. [32] In the North Atlantic, equatorial Pacific, and Southern Ocean, increased wind speeds as well as significant wave heights have been attributed to climate change and natural processes combined.

In meteorology, prevailing wind in a region of the Earth's surface is a surface wind that blows predominantly from a particular direction. The dominant winds are the trends in direction of wind with the highest speed over a particular point on the Earth's surface at any given time.
