Advective Heat Transport to the Red Sea at the Strait of Bab-el-Mandab

The semi-enclosed nature of the Red Sea can be used as a test volume in an attempt to assess the accuracy of climatological airsea interface fluxes, if the advective heat transport at Bab-el-Mandab is accurately known. However, there are few estimates of the advective heat to the Red Sea and even they differ significantly. A review of these estimates is made. It is shown that based on an evaporation rate of 2m.a?1, and the monthly mean volume transports and average temperatures for the two/three layers near the sill, as shown from the previous studies, the annual average advective heat transport to the Red Sea is about 17W.m2.
