Note:
1) Ambient wind sustained at 19.5 m above surface to generate fully-developed seas.
To convert to another altitude h2, apply V2 = V1 ¢ (h2=19:5)1=7.
2) Minimum is 5 percentile and maximum is 95 percentile for periods given wave
height range.
3) Based on periods associated with central frequencies included in Hindcast Climatology. |
