Sea level variations at Jeddah : eastern coast of the Red Sea

Abstract EN

The sea level variations at Jeddah during the year 2000 were investigated.

Tidal analysis showed that tide is responsible for 16.7% of the variance.

The daily-averaged residual (de-tided) sea level was statistically compared with daily means of atmospheric parameters that could contribute to sea level variations.

Evaporation contribution was relatively significant during the late fall, while during early summer its contribution was smaller by about 50%.

Atmospheric pressure has almost no contribution during the early summer but it showed significant contribution during both early winter and late fall.

For the overall record, the along-shore wind stress component showed relatively significant contribution in comparison with the cross-shore component, however, both wind stress components showed significant contribution during the early summer.
