The Atlantic Multidecadal Oscillation (AMO) affects the North Atlantic Oscillation (NAO) and changes its impact on European climate. The AMO shifts the NAO centers of action closer to Europe or North America, altering weather patterns. During AMO+ states, the Icelandic Low moves towards North America, while the Azores High moves towards Europe, and vice versa for AMO- states. This shift in the NAO's spatial structure influences regional climate variables in the Baltic Sea, like sea surface temperature, ice extent, and river runoff.
