While the impact of the El Niño–Southern Oscillation (ENSO) on the stratospheric circulation
has been long recognized, its effects on stratospheric ozone have been less investigated. In …

Specified dynamics schemes are ubiquitous modeling tools for isolating the roles of
dynamics and transport on chemical weather and climate. They typically constrain the …

Stratosphere‐Troposphere exchange (STE) of air mass and ozone in ERA5 and Modern Era
Retrospective analysis for Research and Application, version 2 (MERRA2) reanalyses from …

Large-scale tracer transport in the upper troposphere and lower stratosphere (UTLS) is
investigated using simulations of the Whole Atmosphere Community Climate Model …

We analyze the variability of mean age of air (AoA) and of the local effects of the
stratospheric residual circulation and eddy mixing on AoA within the framework of the …

Small-Scale Wind Fluctuations in the Tropical Tropopause Layer from Aircraft

Abstract The Brewer‐Dobson Circulation (BDC) determines the distribution of long‐lived
tracers in the stratosphere; therefore, their changes can be used to diagnose changes in the …

Mean age of air (AoA) is a widely used metric to describe the transport along the Brewer–
Dobson circulation. We seek to untangle the effects of different processes on the simulation …

The stratospheric quasi-biennial oscillation (QBO) is known to cause variations in the
transport of chemical tracers but the role of chemical processes in modulating their QBO …
