Metadata#
- Note
- The random nature of surface waves implies that individual waves can be substantially higher than the significant wave height. Highest individual waves in a typical storm with typical duration are approximately two times the significant wave height.
- Remark
- Waves higher than roughly twice the significant wave height fall into the category of freak or rogue waves
