Spaceborne lidar shows that more ice than expected is leaving the tropical tropopause layer in the atmosphere.
An exceptionally strong stratospheric polar vortex coincided with a record-breaking Arctic Oscillation pattern and ozone destruction during the 2019–2020 winter season.
Rapid temperature spikes in the stratosphere above Antarctica can influence weather and spark cyclones in the Northern Hemisphere’s tropics.
Chemical signature and chemical transport analyses help understand the dynamics of the Asian Summer Monsoon.
A new study indicates that better atmospheric monitoring networks are needed to enforce the Montreal Protocol.
The first study to examine the ability of a suite of general circulation models to predict sudden warmings in Earth’s stratosphere highlights the potential for improving Northern Hemisphere forecasts.
El Niño events have significant global impacts on weather and climate, but these reach up into the stratosphere, beyond the troposphere where most of Earth’s weather takes place.

Ten years of high-resolution gridded NEXRAD radar data provide a new data set to quantify tropopause-overshooting convection over the continental United States.
Cross-tropopause ozone transport in midlatitude cyclones, coincident with dry air intrusions, is derived from satellite and reanalysis data organized in cyclone-centric coordinates.
