| Analyses of the daily means of the sea level at Jeddah and Port Sudan for the year 1991 reveal that a large proportion (60%) of the energy is concentrated in the seasonal variations. The seasonal signal is approximated as the sum of an annual and semi-annual components. The amplitudes of the annual component are 20.3 and 12.7 cm respective! y and constitute about 44% of the total variance. The amplitudes of the semi-annual cycle are 9.6 cm and 7.7 cm and explain about 10% and 16% of the variance respcctively. At Jeddah cross-spectral anal ysis between the sea-level and the wind stress components shows that the annual cycle is mainly induced by the long-shore component. In contrast no correlation exists between the sea leve! and the cross-shore wind-stress... |
