Atlantic Multidecadal Oscillation

The Atlantic Multidecadal Oscillation (AMO) is a natural climate pattern in the North Atlantic Ocean, characterized by long-term changes in sea surface temperatures. It has warm and cool phases that last several decades each. These phases influence weather and climate across the Atlantic region and beyond, impacting rainfall, hurricane activity, and temperature patterns in North America and Europe. Understanding the AMO helps scientists better predict climate variability, aiding in preparation for potential weather-related impacts.
