Holocene evolution of the Southern Hemisphere westerly winds in transient simulations with global climate models
The Southern Hemisphere Westerly Winds (SWW) have been suggested to exert a critical influence on global climate through the wind-driven upwelling of deep water in the Southern Ocean and the potentially resulting atmospheric CO2 variations. The investigation of the temporal and spatial evolution of the SWW along with forcings and feedbacks remains a significant challenge in climate research. In...
متن کاملDecadal Patterns of Westerly Winds, Temperatures, Ocean Gyre Circulations and Fish Abundance: A Review
The purpose of this review is to describe the global scope of the multidecadal climate oscillations that go back at least, through several hundred years. Literature, historic data, satellite data and global circulation model output have been used to provide evidence for the zonal and meridional jet stream patterns. These patterns were predominantly zonal from the 1970s to 1990s and switched sin...
متن کاملComparing the impacts of tropical SST variability and polar stratospheric 3 ozone loss on the Southern Ocean westerly winds
24 Observed 850 hPa westerly wind trends over the Southern Ocean during 1979-2011 exhibit 25 strong regional and seasonal asymmetries. On an annual basis, trends in the Pacific Sector 26 (40°S-60°S; 70°W-160°W) are significant and three times larger than zonal-mean trends related 27 to the increase in the Southern Annular Mode (SAM). Seasonally, the SAM-related trend is 28 significant in austra...
متن کاملRapid subsurface warming and circulation changes of Antarctic coastal waters by poleward shifting winds
The southern hemisphere westerly winds have been strengthening and shifting poleward since the 1950s. This wind trend is projected to persist under continued anthropogenic forcing, but the impact of the changing winds on Antarctic coastal heat distribution remains poorly understood. Here we show that a poleward wind shift at the latitudes of the Antarctic Peninsula can produce an intense warmin...
متن کاملResponses of ocean circulation and carbon cycle to changes in the position of the Southern Hemisphere westerlies at Last Glacial Maximum
We explore the impact of a latitudinal shift in the westerly wind belt over the Southern Ocean on the Atlantic meridional overturning circulation (AMOC) and on the carbon cycle for Last Glacial Maximum background conditions using a state-of-the-art ocean general circulation model. We find that a southward (northward) shift in the westerly winds leads to an intensification (weakening) of no more...
