Verification of Fleet Numerical Weather Central wave analyses.

Fleet Numerical Weather Central (FNWC) wave period and
height analyses for a selected grid point were verified by
comparison with wave conditions recorded by a coastal wave
sensor at San Clemente Island, California. Forty-six per
cent of the FNWC wave heights were within ±1 foot of the
recorded heights, 75% were within ±2 feet, and 92% were
within ±4 feet. The FNWC heights were found to be over-predicted
by 1.0 feet relative to the recorded waves. Twenty-
six per cent of the FNWC periods were within ±1 second of
the recorded periods, 45% were within ±2 seconds, 66% were
within ±4 seconds, and 90% were within ±6 seconds. There
was no tendency for FNWC to over or underpredict swell
periods, but wind -wave periods were underpredicted on the
average by five seconds.
