In physical oceanography, the significant wave height (SWH, HTSGW or Hs) is defined traditionally as the mean wave height (trough to crest) of the highest third of the waves (H1/3). Nowadays it is usually defined as four times the standard deviation of the surface elevation – or equivalently as four times the square root of the zeroth-order moment (area) of the wave spectrum. The symbol Hm0 is usually used for that latter definition. The significant wave height (Hs) may thus refer to … In oceanography, sea state is the general condition of the free surface on a large body of water—with respect to wind waves and swell—at a certain location and moment. A sea state is characterized by statistics, including the wave height, period, and spectrum. The sea state varies with time, as the wind and swell conditions change. The sea state can be assessed either by an experienced ob…

WebThe main characteristics of sea waves are height, which is the vertical distance between the crest and the trough of the wave; length, which is the horizontal distance between two adjacent crests or troughs; the velocity of motion of the wave shape, or phase velocity; and the period.

WebMaximum wave height: The highest reported wave height over a long duration (e.g. one day) and can be twice the significant wave height. Figure 6: Statistical wave distribution (The COMET Program) The depth of the water also has an impact on swell characteristics. As waves move into shallow water, the waves begin to interact with the sea bed.

WebTsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. They speed along as fast as jet planes. As they near land, these waves rear up to great heights and can drown whole islands. Historically tsunamis have been referred to as tidal waves, but that name is discouraged by oceanographers because tides have little effect on tsunamis.
