A Major Ocean Current Is at Its Weakest Point in 1,000 Years

Webb20 mars 2024 · In the Atlantic Ocean, a giant ‘ conveyor belt ’ carries warm waters from the tropics into the North Atlantic, where they cool and sink and then return southwards in the deep ocean. This circulation pattern is an important player in the global climate, regulating weather patterns in the Arctic, Europe, and around the world. Webb9 aug. 2024 · The AMOC is a large system of ocean currents. It is the Atlantic branch of the ocean conveyor belt or Thermohaline circulation (THC), and distributes heat and nutrients throughout the world’s ocean basins. AMOC carries warm surface waters from the tropics towards the Northern Hemisphere, where it cools and sinks. WebbThe Atlantic meridional overturning circulation ( AMOC) is part of a global thermohaline circulation in the oceans and is the zonally integrated component of surface and deep currents in the Atlantic Ocean. It is characterized by a northward flow of warm, salty water in the upper layers of the Atlantic, and a southward flow of colder, deep waters. patoflowdiagram

Slow-Motion Ocean: Atlantic’s Circulation Is Weakest in 1,600 Years

Webb8 okt. 2009 · This very large, slow current is called the thermohaline circulation because it is caused by temperature and salinity (haline) variations.
