Recent Mediterranean Outflow Water and Atlantic Meridional Overturning Circulation correlations
The Atlantic Meridional Overturning Circulation (AMOC) is the main contributor to the heat interchange in the North Atlantic, carrying around 1.5 PW at 25°N, which helps to regulate the climate, especially in Europe. Any slowdown of the AMOC would produce an important decrease in the temperature in...
