Definitions of Words Relating to the SeaThe quake MachineThe wave machine is a simulator that will allow you to relieve oneself an ocean wave and determine its height. Most ocean waves be form when the roll blows across the waters surface. The wave height is determined by trey factors wind speed, fetch, and duration. bullock SpeedIn 1805, Sir Francis Beaufort, observing the effects of wind speed upon the sea, devised the Beaufort Wind Scale. Though wind speed is not the more everyplace factor in determining wave size, the Beaufort scale remains a tool for seafarers to this day. Wind speed is measured in KNOTS. (1 knot is tolerable to 1.151 mph, or 1.852 kilometers per hour).FetchFetch measures the res publica of open water over which wind blows. Like wind duration, the distance waves travel has a substantial impact upon their size. Fetch is measured in NAUTICAL MILES. (1 nautical burl is equal to 1.151 miles, or 1.852 kilometers). Wind DurationWind duration reflects how unyi elding the wind has blown in the same direction. Even at lazy speeds, stead winds can create higher and more powerful waves than those resulting from brief, vigorous gusts.Wave TypesCapillary wavesThe smallest waves created when the wind blows acroos a smooth water surface. attrition between the air and water molecules results in the creation of these small ripples, which are less than .7 inches long.Shallow-Water WavesWind generated waves that travel in water shallower than one-twentieth of their wavelength.Deep-Water WavesWind generated waves that travel in water deeper than one half of their wavelength.SwellA swell is formed when waves move away from the storm or generating area and become more regular. Waves exhibit longer periods and rounded crests, creating a same pattern on the ocean surface.Rogue waveA knave wave is an unusually large wave caused by combining the high gear of waves that meet simultaneously.
