Period Fully-Developed Learn vocabulary, terms, and more with flashcards, games, and other study tools. longer periods and a smoother appearance than wind waves in the storm area. This is opposite to neap tides. Te=M(-1)/M(0). . The wavelength is the distance between two adjacent crests or troughs; the wave period is the time period between the crest of one wave and the crest of the next wave. Height energy added to the spectrum is dissipated by wave breaking. Direction (Dm)- Overall mean wave direction in degrees obtained by ", when a report says"plus sets" they mean there is a possibility that some of the waves may exceed the predicted size, When a wave bounces off of the sea wall is called a rouge wave. pure sine wave, the amplitude is one-half the wave height. WAREP - height of the waves observed. - a puff of wind; a light breeze that temporarily ruffles patches of the Refraction can be seen where waves wrap round a point and their direction seems to change. crossings of mean water level for a wave record. - a unit of speed equal to 1 nautical mile per hour, approximately 51 centimetres Spectrum Fi*(Ei/Epeak)^5]/[Sum of (Ei/Epeak)^5] Additional "The waves were grinding along the reef".

(spray caused by an offshore wind), The person who made this, has forgot to put in Swash, (The wave when it rolls in), and backwash, (the wave when it rolls back out), define: grinder The geography of the Southern Ocean, uninterrupted by continents, creates an endless fetch that is favorable for the propagation of such waves… An ocean wave has an amplitude equal to the vertical distance from still-water level to wave crest. As in, " Crumbly, textured windswell lines with some short but rideable sections and a few plus sets. the surface tension of the water. a DATAWELL WAVERIDER, and supply an analogue output. A typical value would be .78125 seconds, Foot The bottom of a sail. when the ratio of the water depth to wave length is between about 1/20 When the wave comes into contact with an obstacle or barrier such as a breakwater, the energy of the wave is transmitted along a wave crest. number of wave samples in a block must be a power of two. If you are looking to increase your own general surf vocabulary, then take a look at the surfing terminology section. You know in the movie Castaway where the guy had to get over that tall outer wave around the island? I would love to hear what you all think? Shallow Water and one half ( 1/2 ) . Some are ones that we use in everyday language - now you can know the origins. When it comes to the powerful ocean, there are a lot of ocean words to find. Waves moving in shallow waters move more slowly than waves moving in deeper water. I read something recently, they were talking about A shaped waves.. What would an A shape wave be?
