Record #199698:

Distinct modes of internal variability in the global meridional overturning circulation associated with the Southern Hemisphere westerly winds / Wei Wei, Gerrit Lohmann, Mihai Dima.

Title: Distinct modes of internal variability in the global meridional overturning circulation associated with the Southern Hemisphere westerly winds / Wei Wei, Gerrit Lohmann, Mihai Dima.

Abstract: Highlights decadal and longer time-scale internal variability of global meridional overturning circulation (GMOC) driven by Southern Hemisphere westerly wind (SWW) anomalies based on model simulations. Identifies dominant modes of GMOC internal variability at decadal and longer time scales; finds and distinguishes forcing mechanisms that control different modes; and analyzes influence of corresponding modes on climate. Strengthening and poleward shift of SWW were found to generate direct response in Southern Ocean (SO), with Ekman transport enhanced and Deacon cell strengthened. Such change in SO circulation produces increase of North Atlantic Deep Water outflow in one decade, eventually propagating this anomaly to North Atlantic Ocean after centuries.
