Short summary

We looked into how a numerical experiment represents the interactions between the air and the sea at scales of about 100–1000 km. We found that slight changes in sea surface temperature (SST) drive dramatic modifications in evaporation rates from the sea surface. Cold sea patches tend to cool down the air and to keep moisture trapped within the lower atmospheric layers. Warmer SST, instead, makes them more buoyant and inflate with drier air, thus diluting moisture over thicker air layers.
