Description 717-721
In the Red Sea the haline flux is negative throughout the year
and its contribution is secondary compared to thermal flux. At the northern
region, from October to March, the thermal buoyancy flux is more negative
compared to central and southern regions. As a response to the pressure
gradient generated by this negative buoyancy flux in winter, a NNW surface
current will be induced. During this time, the winds over the southern Red Sea are from SSE. The two forcing factors; buoyancy
flux and the wind stress will reinforce the NNW flow. During summer, from June
to September, there is a reverse pattern of buoyancy flux to that of winter
i.e. a positive buoyancy flux in the north and negative in the central and
southern regions. This buoyancy pattern will generate a pressure gradient
towards the south resulting in a SSE flow. During this time the winds over the Red Sea are from NNW. The two forcing; pressure gradient
towards the south and the NNW winds will favour each other to induce SSE
surface current.
