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.
