WebA 30 min sample included a wave with a zero upcrossing period longer than T z =25 s. For such waves to be wind generated, extreme wind speeds exceeding hurricane strength over a fetch of more than 4000 km for several hours would be required (WMO, 1998, p. 44), which appears unrealistic over the North Sea. EI 3. WebHs - Significant wave height, an average of the highest third of the waves in a record (26.6 minute recording period). Hmax - The maximum wave height in the record. Tz - The zero upcrossing wave period. Tp - The peak energy wave period. Dir_Tp TRUE - Direction (related to true north) from which the peak period waves are coming from.
