Energy that travels through the ocean, created by friction between storm driven winds and the ocean directly in contact with it. The greater the wind the greater the wave is produces.
Waves travel roughly in the direction of the creating wind.
The speed at which the wave travels is determined by the wind strength and the area of the ocean that the wind is covering. In other words, the larger the storm the faster the wave that it creates. The combination of the speed of the wave and the size of the wave determines how much energy the wave contains.
