A recent study funded by @DegreesNGO, executed by @peteirvine & others aims "to assess the impact of #SAG on Sea Surface Temperature (SST) in the Gulf of Guinea & its causes using GLENS simulations performed under high anthropogenic emission scenario (RCP8.5)."

"Study focus on two dynamically different regions:
🔸Sassandra Upwelling in Côte d’Ivoire (SUC, located east of Cape Palmas)
🔸Takoradi Upwelling in Ghana (TUG, located east of Cape Three Points)"

Results show that "in the SUC region, under climate change, there is an increase in SST (referred to as the current climate) all year long (by 1.52 °C on average) mainly due to an < in net heat flux (lead by the > in longwave radiation) & also in weak vertical mixing."

"Under SAG, SST decreases all the seasonal cycle with its maximum in Dec (−0.4 °C) due to a reduction in the net heat flux (caused by a diminution of #SolarRadiation) & an increase in vertical advection (due to an increase in vertical temp. gradient & vertical velocity)."
4/8

"In the TUG region, under climate change, SST warming is a little more intense than in the SUC region and SST changes are driven by an increase in the net heat flux and strong stratification."
5/8

"The cooling of the SST in TUG is similar to the SUC region, but contrary to this region, the cooling
under SAG is not only explained by a decrease in the net heat flux but also by the remote forcing of
wind changes at the western equatorial Atlantic."
