Abstract: Poleward-breaking Rossby waves often induce an upper-level jet streak over northern Europe. Dominant inertia?gravity wave packets are observed downstream of this jet. The physical processes of their generation and propagation, ...

Abstract: A statistical analysis shows that the decadal change of zonally asymmetric total ozone (Total Ozone Mapping Spectrometer data) has a distinct spatial similarity with the decadal change of the 300-hPa geopotential patterns ...

Abstract: The link between poleward-breaking Rossby waves and stratospheric inertia?gravity waves is examined. With a visual inspection of Ertel?s potential vorticity maps based on ECMWF analyses it was found that Rossby wave?breaking ...

Abstract: The characteristics of the poleward advection of upper-tropospheric air are investigated using meteorological analyses and idealized numerical models. Isentropic deformations of the tropopause during Northern Hemisphere ...

Abstract: everal studies show that the anomalous long-lasting Russian heat wave during the summer of 2010, linked to a long-persistent blocking high, appears mainly as a result of natural atmospheric variability. This study analyzes ...

Abstract: ropospheric forcing of planetary wavenumber 2 is examined in the prephase of the major stratospheric sudden warming event in January 2009 (MSSW 2009). Because of a huge increase in Eliassen?Palm fluxes induced mainly by ...

Abstract: AbstractThe vertical coupling between the stratosphere and the mesosphere is diagnosed from polar cap temperatures averaged over 60°?90°N with a new method: the joint occurrence of a warm stratosphere at 10 hPa and a cold ...
