Constraining the exchange through the strait of Bab el Mandab
The strait of Bab el Mandab connects the Red Sea with the Indian ocean via the Gulf of Aden. The mean circulation at the strait is a three-layered exchange. The circulation in the Red Sea is understood to be driven by the air - sea fluxes, such as, evaporation and heat loss. We modify a thermohaline...

The strait of Bab el Mandab connects the Red Sea with the Indian ocean via the Gulf of Aden. The mean circulation at the strait is a three-layered exchange.

We modify a thermohaline circulation (THC) model originally developed for the Nordic Seas and Arctic Mediterranean by Eldevik and Nilsen (2010) to constrain the variability of THC at Bab el Mandab.
