A localized forcing poleward of the climatological storm tracks produces a tropical climate response pattern that is nearly independent of the forcing location. Regardless of the location of extratropical forcing, a common zonally asymmetric La Niña-like pattern of sea surface temperature response accompanies a northward shift of the Intertropical Convergence Zone. In contrast, a localized tropical forcing produces essentially opposite tropical climate response patterns depending on the forced ocean basin. The northern tropical Pacific (Atlantic) heating induces a warming (cooling) throughout the tropical Pacific, a weakening (strengthening) of the equatorial Pacific trade winds, and a northward (southward) shift of the Southern Pacific Convergence Zone. Our study provides a pathway forward for improving future projections of tropical climate under different anthropogenic forcing scenarios. ©2018. American Geophysical Union. All Rights Reserved. |
