Atlantic Meridional Overturning Circulation
The Atlantic Meridional Overturning Circulation (AMOC) is at risk of imminent collapse, with recent studies indicating that anthropogenic emissions could expedite this between 2025 and 2095.
- About: AMOC is a large-scale oceanic circulation system that transports warm surface waters from the tropics to the northern latitudes and returns…
- Warm Water Transport: AMOC transports warm, salty surface waters from the tropics to the northern regions
- Cooling and Density Increase: As the warm surface waters move towards the poles, they gradually cool due to heat loss to the atmosphere
- Downwelling: Once cooled, the dense, cold water sinks to deeper layers of the ocean in a process known as downwelling
Show 6 more facts
- This southward flow represents the deep limb of the AMOC, where cold, dense water mass redistributes heat and nutrients throughout the ocean.
- As the water resurfaces, it begins to warm up again, completing the circulation cycle of the AMOC.
- Role of Indian Ocean: As the Indian Ocean warms faster and faster, it generates additional precipitation
- This saltier water in the Atlantic, as it comes north via AMOC, will get cold much quicker than usual and sink faster.
- This would act as a jump start for AMOC, intensifying the circulation.
- This influx has lowered water salinity and density, causing the colder ocean layer to expand while the warmer layer contracts.
