Multitimescale variations in modeled stratospheric water vapor derived from three modern reanalysis products [PDF]
Atmospheric Chemistry and Physics, 2019 Stratospheric water vapor (SWV) plays important roles in the radiation budget and ozone chemistry and is a valuable tracer for understanding stratospheric transport.

Satellite observations of gravity wave momentum flux in the mesosphere and lower thermosphere (MLT): feasibility and requirements [PDF]
Atmospheric Measurement Techniques, 2022 In the recent decade it became evident that we need to revise our picture of how gravity waves (GWs) reach the mesosphere and lower thermosphere (MLT). This has consequences for our understanding not just of the properties of the GWs themselves, but in ...

A mountain ridge model for quantifying oblique mountain wave propagation and distribution [PDF]
Atmospheric Chemistry and Physics, 2023 Following the current understanding of gravity waves (GWs) and especially mountain waves (MWs), they have a high potential for horizontal propagation from their source. This horizontal propagation and therefore the transport of energy is usually not well

The stratospheric Brewer–Dobson circulation inferred from age of air in the ERA5 reanalysis [PDF]
Atmospheric Chemistry and Physics, 2021 This paper investigates the global stratospheric Brewer–Dobson circulation (BDC) in the ERA5 meteorological reanalysis from the European Centre for Medium-Range Weather Forecasts (ECMWF).

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.

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.

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.
