Abstract: ynamical coupling between the stratospheric and tropospheric circumpolar circulations in the Arctic has been widely documented on month-to-month and interannual time scales, but not on longer time scales. In the Antarctic, ...

Abstract: adiative and dynamical heating rates control stratospheric temperatures. In this study, radiative temperature trends due to ozone depletion and increasing well-mixed greenhouse gases from 1980 to 2000 in the polar stratosphere ...

Abstract: AbstractMuch research has focused on trends in the Southern Hemispheric circulation in austral summer (December?February) in the troposphere and stratosphere, whereas changes in other seasons have received less attention. ...
