Geostrophic currents along the Eastern coast of the central Red Sea

Abstract EN

Geostrophic computations of currents along the eastern coast of the Red Sea between 21° -24°N show that the surface circulation is mainly governed by the seasonal wind system.

During November 1977 and December 1982 geostrophic currents were directed in a north-northwest direction under the influence of the south-southeasterly winds of the southern half of the Red Sea.

In March 1982 the currents were weak and variable except at the northernmost section where the current had reversed to south-southeast under the influence of the north-northwesterly winds.

In May 1978 geostrophic currents were in a south-southeasterly direction.

The current meter data during May 1978 also show that the current direction is the same as obtained from geostrophic computations.
