We review and discuss some different techniques for describing local dispersion properties
in fluids. A recent Lagrangian diagnostics based on the finite scale Lyapunov exponent …

The MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) instrument has
been operating on-board the ENVISAT satellite since March 2002. In the first two years, it …

Stratospheric sudden warmings are the clearest and strongest manifestation of dynamical
coupling in the stratosphere–troposphere system. While many sudden warmings have been …

Chemical loss of Arctic ozone due to anthropogenic halogens is driven by temperature, with
more loss occurring during cold winters favourable for formation of polar stratospheric …

A strong link exists between stratospheric variability and anomalous weather patterns at the
earth's surface. Specifically, during extreme variability of the Arctic polar vortex termed a …

The wintertime Arctic stratospheric polar vortex has weakened over the past three decades,
and consequently cold surface air from high latitudes is now more likely to move into the …

Attribution of Antarctic ozone recovery to the Montreal protocol requires evidence that (1)
Antarctic chlorine levels are declining and (2) there is a reduction in ozone depletion in …

In this paper, we describe the construction of the Stratospheric Water and Ozone Satellite
Homogenized (SWOOSH) database, which includes vertically resolved ozone and water …

Climatology of Arctic and Antarctic Polar Vortices Using Elliptical Diagnostics in: Journal of the
Atmospheric Sciences Volume 56 Issue 11 (1999) Jump to Content Logo Logo Logo Logo …

Recent satellite observations and dynamical studies have demonstrated the existence of
filamentary structures in chemical tracer fields in the stratosphere. It is also evident that such …
