AMOC decadal variability: links to the subpolar ocean.
Not exact matches
In a recent paper, Sanchez - Franks and Zhang show that the underlying physical driver for the
decadal variability in the Gulf Stream path and the regional biogeochemical cycling is linked to the low - frequency
variability of the large - scale ocean circulation in the Atlantic, also known as Atlantic meridional overturning circulation (
AMOC).
Further,
AMOC - induced
decadal variability in chlorophyll and nutrient concentrations in the Gulf Stream region might be important for changes in the localized carbon cycle and fisheries at
decadal timescales.
How can the CMIP6
decadal MIPs be used to understand
AMOC variability and related climate impacts?
Specific attention is given to
variability of the Atlantic Meridional Overturning Circulation (
AMOC), which is likely the origin of a considerable part of
decadal variability and predictability in the Atlantic Sector.
Buoyancy anomalies on the western boundary are key to
decadal AMOC variability, but the origin of these buoyancy anomalies and how they are communicated meridionally is not clear.
On
decadal timescales,
AMOC variability involves a complex interplay between wind - driven and thermohaline (buoyancy - driven) processes.
If the transition zone indeed controls
decadal AMOC variability, monitoring this region may enable scientists to measure and perhaps predict
AMOC variability, with potential impacts for interannual - to -
decadal climate predictions.
I linked studies showing a link of SAM and NAM to
AMOC and the IPO and thus to a
decadal to millennial scale climate
variability.
And there are a bunch of different time - scales to consider (
decadal to multi-centennial
variability for the
AMOC alone).
Translate the knowledge developed about
AMOC variability and predictability mechanisms into reliable
decadal climate forecasts.
Models and reconstructions seem to agree that the
AMOC has substantial natural
variability on
decadal (10 - 100 years) time scales.
