The efficiency of transport into the stratosphere via the Asian and North American summer monsoon circulations [PDF]
Atmospheric Chemistry and Physics, 2019 Transport of pollutants into the stratosphere via the Asian summer monsoon (ASM) or North American summer monsoon (NASM) may affect the atmospheric composition and climate both locally and globally.

The stratosphere: a review of the dynamics and variability
Weather and Climate Dynamics, 2022 . Large-scale, intra-seasonal to inter-annual variability of the stratosphere is reviewed. Much of the variability is dynamical and induced by waves emanating from the troposphere.

The potential role of stratospheric ozone in the stratosphere‐ionosphere coupling during stratospheric warmings [PDF]
Geophysical Research Letters, 2012 The recent discovery of large ionospheric disturbances associated with sudden stratospheric warmings (SSW) has challenged the current understanding of mechanisms coupling the stratosphere and ionosphere. Non‐linear interaction of planetary waves and tides has been invoked as a primary mechanism for such coupling.

Impact of the 2009 major sudden stratospheric warming on the composition of the stratosphere [PDF]
Atmospheric Chemistry and Physics, 2015 In a case study of a remarkable major sudden stratospheric warming (SSW) during the boreal winter 2008/09, we investigate how transport and mixing triggered by this event affected the composition of the entire stratosphere in the Northern Hemisphere.

Observation of horizontal temperature variations by a spatial heterodyne interferometer using single-sided interferograms [PDF]
Atmospheric Measurement Techniques, 2023 Analyses of the mesosphere and lower thermosphere suffer from a lack of global measurements. This is problematic because this region has a complex dynamic structure, with gravity waves playing an important role.

Long Range Prediction and the Stratosphere
Atmospheric Chemistry and Physics, 2021 . Over recent years there have been parallel advances in the development of stratosphere resolving numerical models, our understanding of stratosphere-troposphere interaction and the extension of long-range forecasts to explicitly include the ...

A potential vorticity-based determination of the transport barrier in the Asian summer monsoon anticyclone [PDF]
Atmospheric Chemistry and Physics, 2015 The Asian summer monsoon provides an important pathway of tropospheric source gases and pollution into the lower stratosphere. This transport is characterized by deep convection and steady upwelling, combined with confinement inside a large-scale ...

Sensitivities of modelled water vapour in the lower stratosphere: temperature uncertainty, effects of horizontal transport and small-scale mixing [PDF]
Atmospheric Chemistry and Physics, 2018 Water vapour (H2O) in the upper troposphere and lower stratosphere (UTLS) has a significant role for global radiation. A realistic representation of H2O is therefore critical for accurate climate model predictions of future climate change.

Characteristics of gravity waves resolved by ECMWF [PDF]
Atmospheric Chemistry and Physics, 2014 Global model data from the European Centre for Medium-Range Weather Forecasts (ECMWF) are analyzed for resolved gravity waves (GWs). Based on fitted 3-D wave vectors of individual waves and using the ECMWF global scale background fields, backward ray ...
