Atlantic Meridional Overturning Circulation

Generalised model of thermohaline circulation, adapted from NASA.

The Atlantic Meridional Overturning Circulation (AMOC) is a system of currents in the Atlantic Ocean, including the Gulf Stream that circulates a vast amount of heat from the tropics towards the North Pole disseminating the cold, saline, dense waters towards the Tropics and even further south towards the South Pole. The figure above captures that in a generalised worldwide model of thermohaline (thermo- referring to temperature and –haline referring to salt content) circulation.

The Paul Hudson Weather Show

In the time I’ve worked at the BBC I’ve made programmes about American blues musicians performing in the former Soviet Union, young offenders being rehabilitated through the arts, Royal Navy convoys protecting NATO peace conferences. I’ve interviewed high profile recording artists, read news bulletins and reported live on breaking news stories. And whatever the inherent difficulties of these assignments were, they were at least tangible and there were facts - a story to tell.
