Quantifying Extreme Events from Short Weather Forecast Data
Subseasonal weather forecast ensembles are a useful tool for overcoming the inherent difficulty of quantifying extreme weather risk caused by data scarcity.
Wildfire Smoke Destroys Ozone
Smoke aerosols from large wildfires are the perfect reaction surface for chlorine chemicals, speeding their transformation from ozone-friendly forms to reactive ones.
Monitoreando el agua en la columna eruptiva masiva del volcán de Tonga
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.
Tracking Water in the Tongan Volcano’s Massive Eruption Plume
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.
Modeling Stratosphere-Troposphere Coupling in a Changing Climate
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.
Simulating Surface Impacts of Stratospheric Sudden Warmings
New evaluations of climate model simulations show how the stratosphere polar vortex couples to surface weather.
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.
