AMOC can regulate wave activities over the mid-to-high latitudes in the Northern Hemisphere, which has a direct impact on extreme weather at mid-to-high latitudes in Eurasia (hereafter referred to as the MHEA). During boreal winters, strong AMOC regulates the Rossby wave train that originates from the North Atlantic and crosses mid-to-high latitudes, which increases the variability in the circulation anomalies in the Ural blocking area and Siberia and…

Schematic diagram of the energy flow over the Atlantic. Credit: Ning Cao, Chunlei Liu The Atlantic Meridional Overturning Circulation (AMOC) is a phenomenon responsible for transporting ocean heat northward through the Atlantic Ocean. This process significantly influences the Arctic and North Atlantic oceanic climate and the Eurasian continental climate. The corresponding cross-equatorial northward heat transport also…
