Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The importance of interactive chemistry for stratosphere–troposphere coupling [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Recent observational and modeling studies suggest that stratospheric ozone depletion not only influences the surface climate in the Southern Hemisphere (SH), but also impacts Northern Hemisphere (NH) spring, which implies a strong interaction between ...

The role of convective overshooting clouds in tropical stratosphere–troposphere dynamical coupling [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
This paper investigates the role of deep convection and overshooting convective clouds in stratosphere–troposphere dynamical coupling in the tropics during two large major stratospheric sudden warming events in January 2009 and January 2010.

Gravity waves as a mechanism of troposphere–stratosphere–mesosphere coupling during sudden stratospheric warming [PDF]

open access: yesAtmospheric Chemistry and Physics
The propagation of gravity waves (GWs) and their role in the coupling of the troposphere–stratosphere–mesosphere atmospheric layers during sudden stratospheric warming (SSW) are studied. A standard set of hydrodynamic (HD) equations is used to derive the

Energetic Particle Forcing of the Northern Hemisphere winter stratosphere: Comparison to solar irradiance forcing

open access: yesFrontiers in Physics, 2014
Variation in solar irradiance is considered an important factor in natural climate forcing. Variations in the solar UV in particular are now regarded as a major source of decadal variability in the stratosphere, influencing surface climate through ...

Quantifying stratospheric biases and identifying their potential sources in subseasonal forecast systems [PDF]

open access: yesWeather and Climate Dynamics, 2022
The stratosphere can be a source of predictability for surface weather on timescales of several weeks to months. However, the potential predictive skill gained from stratospheric variability can be limited by biases in the representation of stratospheric

Impact of the stratosphere on tropospheric climate change

open access: yesGeophysical Research Letters, 2008
The atmospheric circulation response to CO2 doubling in various versions of an atmospheric general circulation model (AGCM) without a well‐resolved stratosphere (“low‐top” model), is compared to the response in a version of the same AGCM with a well ...

Influence of Wintertime Polar Vortex Variation on the Climate over the North Pacific during Late Winter and Spring

open access: yesAtmosphere, 2019
The effects of wintertime stratospheric polar vortex variation on the climate over the North Pacific Ocean during late winter and spring are analyzed using the National Centers for Environmental Predictions, version 2 (NCEP2) reanalysis dataset.

Stratospheric tropical warming event and its impact on the polar and tropical troposphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
Stratosphere–troposphere coupling is investigated in relation to middle atmospheric subtropical jet (MASTJ) variations in boreal winter. An exceptional strengthening of the MASTJ occurred in association with a sudden equatorward shift of the ...

Signature of the stratosphere–troposphere coupling on recent record-breaking Antarctic sea-ice anomalies [PDF]

open access: yesThe Cryosphere, 2023
In February 2023, the sea-ice extent around Antarctica dropped to 1.79×106 km2, setting a satellite-era record low for the second straight year. Recent records stress the need for further research into the factors behind record-breaking Antarctic sea-ice
