Arctic Ozone Loss Brings Warming to the Near Surface
New research confirms that ozone loss over the Arctic can lead to widespread warming near the Artic surface during late winter and early spring.
Australian Wildfires Linked to Ozone Layer Depletion
New research shows that the Black Summer bushfires damaged the ozone layer, eliminating a decade’s worth of progress.
New Insights on Stratospheric Circulation from Fluorine Tracers
Stratospheric fluorine species have accumulated faster in the Northern Hemisphere over the past two decades reflecting interhemispheric differences in the Brewer-Dobson transport circulation.
Convective Transport Explains “Missing” Ice near the Tropical Tropopause
Spaceborne lidar shows that more ice than expected is leaving the tropical tropopause layer in the atmosphere.
Global Effects of Disruptions to the Stratospheric Circulation
Major disruptions to the stratospheric circulation have far-reaching effects, including increased likelihood of snowstorms, growth of the ozone hole, and interference in global telecommunications.
An Extraordinary Winter in the Polar North
An exceptionally strong stratospheric polar vortex coincided with a record-breaking Arctic Oscillation pattern and ozone destruction during the 2019–2020 winter season.
Warming in the Antarctic Stratosphere Affects Tropical Weather
Rapid temperature spikes in the stratosphere above Antarctica can influence weather and spark cyclones in the Northern Hemisphere’s tropics.
Polar Stratosphere Resolves North Atlantic Jet “Tug of War”
Getting the polar stratosphere right is critical in the simulation of North Atlantic climate change, which is shaped by the interaction of Arctic Amplification and tropical upper tropospheric warming.
Banned CFC Emissions Tracked to Eastern China
A new study indicates that better atmospheric monitoring networks are needed to enforce the Montreal Protocol.
