Decade-long cooling cycle: Middle atmosphere in sync with ocean

Relationship between decadal variations in temperatures in the Pacific and the tropopause identified

Summary:

In the late 20th century scientists observed a cooling at the transition between the troposphere and stratosphere at an altitude of about 15 kilometers. Climate scientists now show that the cooling could also be part of a natural decadal variation which is controlled by the water temperature of the Pacific.
