Significant wave height hm0
The RMS wave height, which is defined as square root of the average of the squares of all wave heights, is approximately equal to H s divided by 1.4. For example, according to the Irish Marine Institute: "… at midnight on 9/12/2007 a record significant wave height was recorded of 17.2m at with [sic] a … See more 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 … See more The original definition resulted from work by the oceanographer Walter Munk during World War II. The significant wave height was intended to … See more Although most measuring devices estimate the significant wave height from a wave spectrum, satellite radar altimeters are unique in measuring directly the significant wave … See more A significant wave height is also defined similarly, from the wave spectrum, for the different systems that make up the sea. We then have a significant wave height for the wind-sea or for a particular swell. See more Significant wave height, scientifically represented as Hs or Hsig, is an important parameter for the statistical distribution of ocean waves. The most common waves are lower in height than Hs. This implies that encountering the significant wave is not too frequent. … See more The World Meteorological Organization stipulates that certain countries are responsible for providing weather forecasts for the world's oceans.
