1. Once a wave has been generated its speed may change, but its period does not as this characteristic is determined by the generating force. 2. Deep-water waves (waves of oscillation) a. Deep-water waves occur where the water is deeper than 1/2 the wavelength of the waves. b. In deep water the velocity of a wave is a function of wavelength. c. Waves are created in storm centers or by the steady winds of the westerlies and trades.
In fluid dynamics, wind waves, or wind-generated waves, are surface waves that occur on the free surface of oceans, seas, lakes, rivers, and canals or even on small puddles and ponds. They result from the wind blowing over an area of fluid surface. Waves in the oceans can travel thousands of miles before reaching land. Wind waves range in size from small ripples, to waves over 100 ft (30 m) high. When directly generated and affected by local winds, a wind wave system is called a wind sea.
