Two very thin skins of fluid cover the surface of our planet: a low density layer consisting mainly of gases (our atmosphere), and a higher density layer consisting mainly of water (our oceans). However the two layers are not completely distinct, and exchanges of water, gases, particulate matter, heat and momentum are continually taking place across the interface between them. These exchanges have a profound effect on the development of our weather systems, and in the longer term, the progress of climate variability and change. Explore the sub-topics to learn more about this fascinating interface. (Meteosat image copyright Eumetsat)
