Description 114-122
Daily means of sea level and atmospheric forcing over a period of three years (1991-1993) at Jeddah are examined by spectral and regression methods. The analysis reveals the presence of a large annual and a semi-annual component in the time series. Average amplitudes of the two signals in the sea level changes are 19 and 8 cm, respectively, and account for 58 % of the total variance. The two signals are induced by the combined effect of wind stress and evaporation rate. Wind stress plays a major role in inducing the annual cycle. Sea level is inversely related to the evaporation rate only during the transition periods. Isostatic response of sea level is limited, 4 % of the total variance, and is frequency dependent with observed period of 9 days. Analysis of daily residuals shows that about 78 % of the variance can be modeled by a first order auto-regressive model AR (1).
