Hs |
Height of significant wave (metres). This is the average height of the highest one third of the waves in the record. |
Hmax |
Maximum height of the waves (metres) in the record. |
Tz |
Average wave period. This is the average time (seconds) between all waves in the record. The more technical name for this quantity is the zero-crossing period. |
Tp |
The peak wave period (seconds) is the period at which the peak of the wave spectrum occurs. |
Spectral density |
Distribution of the variance of the surface elevation with wave period or frequency (proportional to the wave amplitude squared). |
