Stratosphere–Troposphere Coupling in the Southern Hemisphere

  title={Stratosphere–Troposphere Coupling in the Southern Hemisphere},
  author={David W. J. Thompson and Mark P. Baldwin and Susan Solomon},
  journal={Journal of the Atmospheric Sciences},
Abstract This study examines the temporal evolution of the tropospheric circulation following large-amplitude variations in the strength of the Southern Hemisphere (SH) stratospheric polar vortex in data from 1979 to 2001 and following the SH sudden stratospheric warming of 2002. In both cases, anomalies in the strength of the SH stratospheric polar vortex precede similarly signed anomalies in the tropospheric circulation that persist for more than 2 months. The SH tropospheric circulation… Expand

On the Role of Radiative Processes in Stratosphere–Troposphere Coupling
Abstract Climate change in the Southern Hemisphere (SH) polar stratosphere is associated with substantial changes in the atmospheric circulation that extend to the earth’s surface. The mechanismsExpand
Seasonal Persistence of Circulation Anomalies in the Southern Hemisphere Stratosphere and Its Implications for the Troposphere

The impact of the stratosphere on the troposphere during the southern hemisphere stratospheric sudden warming, September 2002
Recent research has established that a small but statistically significant link exists between the stratosphere and the troposphere in the northern hemisphere extratropics. In this paper it is shownExpand
Seasonal Evolution of Stratosphere‐Troposphere Coupling in the Southern Hemisphere and Implications for the Predictability of Surface Climate
Stratosphere-troposphere coupling in the Southern Hemisphere (SH) polar vortex is an important dynamical process that provides predictability of the tropospheric Southern Annular Mode (SAM) and itsExpand
Quantifying the Timescale and Strength of Southern Hemisphere Intraseasonal Stratosphere‐troposphere Coupling
The statistical model can quantitatively connect the multidecadal trends observed in the vortex and jet during the satellite era and shows how short‐term variability can help understand statistical links in long‐term changes. Expand
Interannual Variability in the Southern Hemisphere Circulation Organized by Stratospheric Final Warming Events
Abstract A composite observational analysis is presented demonstrating that austral stratospheric final warming (SFW) events provide a substantial organizing influence upon the large-scaleExpand
Ozone‐induced climate change propped up by the Southern Hemisphere oceanic front

The Dynamics of Northern Hemisphere Stratospheric Final Warming Events
Abstract A lag composite analysis is performed of the zonal-mean structure and dynamics of Northern Hemisphere stratospheric final warming (SFW) events. SFW events are linked to distinct zonal windExpand
Understanding the variation of stratosphere–troposphere coupling during stratospheric northern annular mode events from a mass circulation perspective
We revisit the various stratosphere–troposphere coupling relation from the perspective of the meridional mass circulation. We constructed 10-hPa northern annular mode (NAM) phase composites to showExpand
Classification of stratospheric extreme events according to their downward propagation to the troposphere
This study presents a classification of stratospheric extreme events during northern winter into events with or without a consistent downward propagation of anomalies to the troposphere. AnomalousExpand


Interpretation of Recent Southern Hemisphere Climate Change
Evidence is presented that recent trends in the SH tropospheric circulation can be interpreted as a bias toward the high-index polarity of this pattern, with stronger westerly flow encircling the polar cap. Expand
The Splitting of the Stratospheric Polar Vortex in the Southern Hemisphere, September 2002: Dynamical Evolution
Abstract The polar vortex of the Southern Hemisphere (SH) split dramatically during September 2002. The large-scale dynamical effects were manifest throughout the stratosphere and upper troposphere,Expand
Interannual variability in the troposphere and stratosphere of the southern hemisphere winter
Interannual variability in the tropospheric and stratospheric circulation of the southern-hemisphere winter is studied over the 16-year period from 1979 to 1994. In particular, the interannual modeExpand

Downward Propagation of the Arctic Oscillation from the Stratosphere to the Troposphere
Geopotential anomalies ranging from the Earth's surface to the middle stratosphere in the northern hemisphere are dominated by a mode of variability known as the Arctic Oscillation (AO). The AO isExpand
