Sea surface temperature is an important measure of the heat content on the surface layer of the ocean. It is plays an important role in marine ecology,
as well as ocean-atmosphere interaction. For example, a cold ocean along the west coast of South Africa results inhibits convection, thereby suppressing
rainfall and keeping adjacent landmass relatively dry. The warm Agulhas Current, flowing along South Africa’s east coast, transfers heat energy to the overlaying
atmosphere. This causes air to rise and condense, thereby causing rainfall along the lush east coast.
