Trends in Ocean S‐Isotopes May Be Influenced by Major LIP Events

open access: yesGeophysical Monograph Series, Page 341-376., 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.

Impact of different Asian source regions on the composition of the Asian monsoon anticyclone and of the extratropical lowermost stratosphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
The impact of different boundary layer source regions in Asia on the chemical composition of the Asian monsoon anticyclone, considering its intraseasonal variability in 2012, is analysed by simulations of the Chemical Lagrangian Model of the Stratosphere

Potential of future stratospheric ozone loss in the midlatitudes under global warming and sulfate geoengineering [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
The potential of heterogeneous chlorine activation in the midlatitude lowermost stratosphere during summer is a matter of debate. The occurrence of heterogeneous chlorine activation through the presence of aerosol particles could cause ozone destruction.

Long-range transport pathways of tropospheric source gases originating in Asia into the northern lower stratosphere during the Asian monsoon season 2012 [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Global simulations with the Chemical Lagrangian Model of the Stratosphere (CLaMS) using artificial tracers of air mass origin are used to analyze transport mechanisms from the Asian monsoon region into the lower stratosphere.

The advective Brewer–Dobson circulation in the ERA5 reanalysis: climatology, variability, and trends [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
The stratospheric Brewer–Dobson circulation (BDC) is an important element of climate as it determines the transport and distributions of key radiatively active atmospheric trace gases, which affect the Earth's radiation budget and surface climate ...

Characteristics of gravity waves resolved by ECMWF [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
Global model data from the European Centre for Medium-Range Weather Forecasts (ECMWF) are analyzed for resolved gravity waves (GWs). Based on fitted 3-D wave vectors of individual waves and using the ECMWF global scale background fields, backward ray ...

Lagrangian simulation of ice particles and resulting dehydration in the polar winter stratosphere [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Polar stratospheric clouds (PSCs) and cold stratospheric aerosols drive heterogeneous chemistry and play a major role in polar ozone depletion. The Chemical Lagrangian Model of the Stratosphere (CLaMS) simulates the nucleation, growth, sedimentation, and

Lagrangian simulations of the transport of young air masses to the top of the Asian monsoon anticyclone and into the tropical pipe [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
We have performed backward trajectory calculations and simulations with the three-dimensional Chemical Lagrangian Model of the Stratosphere (CLaMS) for two succeeding monsoon seasons using artificial tracers of air mass origin.

Stratospheric water vapour and ozone response to the quasi-biennial oscillation disruptions in 2016 and 2020 [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
The quasi-biennial oscillation (QBO) is a major mode of climate variability in the tropical stratosphere with quasi-periodically descending westerly and easterly winds, modulating transport and distributions of key greenhouse gases such as water vapour ...

Sudden Stratospheric Warmings [PDF]

open access: yesReviews of Geophysics, 2020
Abstract Sudden stratospheric warmings (SSWs) are impressive fluid dynamical events in which large and rapid temperature increases in the winter polar stratosphere ( ∼ 10–50 km) are associated with a complete reversal of the climatological wintertime westerly winds. SSWs are
