Ocean convection refers to the movement of water in the ocean caused by differences in temperature and density. It occurs when warmer water rises to the surface and colder water sinks to the bottom. This motion helps distribute heat and nutrients in the ocean, influencing climate and marine life.
Full definition
The key however is to integrate over the whole space of internal variability — which includes variations in the North
Atlantic Ocean convection.

of ocean convection posed by warm North Atlantic summers.
For instance, changes in
ocean convection over the north Atlantic would affect the jet stream, which would have a dramatic effect upon regional precipitation, probably leading to acute drought in the northern hemisphere, which will weaken and push the northern jet stream toward the Arctic.

Southern Ocean convection in the Kiel Climate Model.
A decline of open -
ocean convection would reduce the production rate of Antarctic Bottom Waters, with important implications for ocean heat and carbon storage, and may have played a role in recent Antarctic climate change.»
