Inspired by paleoclimate evidence that much past climate change has been symmetric about
the equator, the causes of hemispherically symmetric variability in the recent observational …

Over recent years there have been concomitant advances in the development of
stratosphere-resolving numerical models, our understanding of stratosphere–troposphere …

Recent studies have pointed out the impact of the stratosphere on the troposphere by
dynamic coupling. In the present paper, observational evidence for an effect of downward …

Reanalysis data are used to evaluate the evolution of polar vortex geometry, planetary wave
drag, and gravity wave drag prior to split versus displacement sudden stratospheric …

Does the Holton–Tan Mechanism Explain How the Quasi-Biennial Oscillation Modulates the
Arctic Polar Vortex? in: Journal of the Atmospheric Sciences Volume 69 Issue 5 (2012) Jump to …

Sudden stratospheric warming (SSW) events have received increased attention since their
impacts on the troposphere became evident recently. Studies of SSW usually focus on polar …

Wave and zonal mean features of the downward dynamic coupling between the
stratosphere and troposphere are compared by applying a time-lagged singular value …

The stratosphere contains~ 17% of Earth's atmospheric mass, but its existence was
unknown until 1902. In the following decades our knowledge grew gradually as more …

The Arctic stratospheric polar vortex is an important driver of mid-latitude cold spells. One
proposed coupling mechanism between the stratospheric polar vortex and the troposphere …

This paper examines the nature and robustness of internal stratospheric variability, namely
the variability resulting from the internal dynamics of the stratosphere itself, as opposed to …
