AMO Index

The Atlantic Multidecadal Oscillation (AMO index) is a periodically variation of the flow conditions in the North Atlantic. The circulation patterns are changing with a cycle of 50 to 70 years, leading to far-reaching changes in the sea surface temperature, which consequently impact the overlying atmosphere.
