A new study quantifies the tropospheric and surface impacts of extreme stratospheric wave events and evaluates their representation in state-of-the-art climate models.
Subseasonal weather forecast ensembles are a useful tool for overcoming the inherent difficulty of quantifying extreme weather risk caused by data scarcity.
Smoke aerosols from large wildfires are the perfect reaction surface for chlorine chemicals, speeding their transformation from ozone-friendly forms to reactive ones.
La reciente erupción del volcán Hunga Tonga-Hunga Ha’apai arrojó aerosoles de sulfatos y una cantidad nunca antes vista de vapor de agua a la estratosfera.
The recent eruption of the Hunga Tonga–Hunga Ha‘apai volcano blasted sulfate aerosols and a record-breaking amount of water vapor into the stratosphere.
Climate models have disagreed on the future evolution of the stratospheric polar vortex and links to the troposphere, but a new study revisits this problem with state-of-the-art climate models.
New evaluations of climate model simulations show how the stratosphere polar vortex couples to surface weather.
New research shows that the Black Summer bushfires damaged the ozone layer, eliminating a decade’s worth of progress.
Stratospheric fluorine species have accumulated faster in the Northern Hemisphere over the past two decades reflecting interhemispheric differences in the Brewer-Dobson transport circulation.
Spaceborne lidar shows that more ice than expected is leaving the tropical tropopause layer in the atmosphere.
