Observations show that large variations in the strength of the stratospheric circulation, appearing first above ∼50 kilometers, descend to the lowermost stratosphere and are followed by anomalous tropospheric weather regimes. During the 60 days after the onset of these events, average surface pressure maps resemble closely the Arctic Oscillation pattern. These stratospheric events also precede shifts in the probability distributions of extreme values of the Arctic and North Atlantic… Expand
Stratospheric Memory and Skill of Extended-Range Weather Forecasts
An empirical statistical model is used to demonstrate significant skill in making extended-range forecasts of the monthly-mean Arctic Oscillation and provides evidence that both the time scale and predictability of the AO depend on the presence of persistent circulation anomalies just above the tropopause.

Predictability of the coupled troposphere-stratosphere system
Tropospheric predictability is typically limited to about 20 days due to the chaotic nature of weather. The tropospheric variability contains planetary waves which can propagate vertically into theExpand
Stratosphere–Troposphere Coupling in the Southern Hemisphere
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 inExpand
The stratosphere and the troposphere exhibit a strong coupling during the Northern Hemisphere winter season. This coupling is particularly strong during the formation of major or minor SuddenExpand
Stratospheric predictability and sudden stratospheric warming events
[1] A comparative study of the limit of predictability in the stratosphere and troposphere in a coupled general circulation model is carried out using the National Center for Environmental PredictionExpand
Wintertime North American Weather Regimes and the Arctic Stratospheric Polar Vortex
The impact of the Arctic stratospheric polar vortex on persistent weather regimes over North America is so far under-explored. Here we show the relationship between four wintertime North AmericanExpand
Stratospheric Connection to Northern Hemisphere Wintertime Weather: Implications for Prediction
The dynamical coupling between the stratospheric and tropospheric circulations yields a statistically significant level of potential predictability for extreme cold events throughout much of theExpand
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
The solar cycle and stratosphere–troposphere dynamical coupling
Abstract Observations and modeling studies support the hypothesis that solar cycle/ozone interactions create temperature and wind anomalies in the tropical upper stratosphere near 1 hPa. DuringExpand
Simulation of Recent Southern Hemisphere Climate Change
The results provide evidence that anthropogenic emissions of ozonedepleting gases have had a distinct impact on climate not only at stratospheric levels but at Earth's surface as well. Expand
