Abstract : Meteorological and tidal records at three Florida Gulf coast stations have been examined for the period 1965-67. Cross spectral analysis of daily winds and sea levels showed a high coherence at periods of 4 to 20 days. Daily sea levels have been correlated with winds of varying directions and speeds with good results. Sea level was found to be most responsive to winds that were within about 10 degrees of parallel to the direction of the coastline. A longshore wind of 4.5 m/sec caused a sea level fluctuation of 20 cm. Onshore-offshore winds did not produce sea level fluctuations that were discernible above the noise level. Wind components at weather stations separated by up to 300 km were found to have coherence above 0.6 for the periods of 4 to 100 days. (Modified author abstract)
