Stratospheric Aerosols from Major Volcanic Eruptions: A Composition-Climate Model Study of the Aerosol Cloud Dispersal and e-folding Time

Atmosphere, 2016
Large explosive volcanic eruptions are capable of injecting considerable amounts of particles and sulfur gases above the tropopause, causing large increases in stratospheric aerosols. Five major volcanic eruptions after 1960 (i.e., Agung, St.

Historical Volcanic Eruptions Mitigated the Expected Rapid Arctic Sea Ice Decline Prior to 2000

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Arctic sea ice has declined at sharply contrasting rates over the past four decades—modest before 2000 and rapid thereafter. Using observational and model evidence, we show that large tropical volcanic eruptions can trigger decade‐long Arctic sea ice recoveries, and that without the 1982 El Chichón and 1991 Pinatubo eruptions, Arctic sea ice ...

Enormous increase of volcanic clouds in the stratosphere over Fukuoka after April 1982

Geofísica Internacional, 1984
Mediante el sistema lidar Yag se observaron sobre Fukuoka (33°N) aumentos muy grandes de los aerosoles estratosféricos causados por la erupción del volcán mexicano El Chichón, a principios de abril de 1982.

Attribution of Recent Change in the Stratospheric Temperature and Its Application to Future Projection

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The stratospheric temperature has continued to decline over the past half‐century, in contrast to the steady increase in the tropospheric temperature. However, the future changes in stratospheric temperature under anthropogenic influences, as well as the specific role of stratospheric interactive chemistry in their attribution and projection ...

Geometry of the Benioff zone in the Tehuantepec area in Southern México

Geofísica Internacional, 1982
Mediante el uso de. datos de las estaciones VHO, COM y una red sísmica local que operó durante 1979 en Chiapas, en el sureste de México, la geometría de la zona de Benioff mas allá de los 60 km de profundidad ha sido bien delimitada en el área de ...

Manufacturing Consent: Faragism and the Hegemonic Struggle for Britain

Sociology Compass, Volume 20, Issue 5, May 2026.
ABSTRACT This paper analyses ‘Faragism’, the right‐wing populist movement associated with Nigel Farage, not as a transient political moment but as an evolving hegemonic project that has reshaped British politics. Drawing on Gramsci, and on subsequent elaborations by Hall, Laclau, and Mouffe, it develops a three‐phase model explaining how such movements

On CMIP6 Model Consensus for the Climate Response in Eurasian Winter to Historical Volcanic Eruptions

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract This study provides a comprehensive analysis of the climate response in Northern Hemisphere (NH) winter to major volcanic eruptions of the past, using multi‐member ensembles of historical experiments of 15 models from the Coupled Model Intercomparison Project Phase 6 (CMIP6) and three reanalysis data sets.

Change in Tropical Cyclone Efficiency Under Different ENSO Conditions in the Western North Pacific Ocean

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Tropical cyclones (TCs) can be considered as Carnot heat engines, where thermodynamic efficiency depends on the sea surface temperature (SST) and TC outflow temperature (To) in the upper atmosphere. This study investigates how TC efficiency in the western North Pacific (WNP) Ocean varies under different El Niño‐Southern Oscillation (ENSO ...

Temporal variations in characteristics of the El Chichón stratospheric cloud

Geofísica Internacional, 1984
Durante el periodo comprendido desde abril hasta diciembre de 1982 se hicieron mediciones y muestreos in situ de la nube de la erupción de El Chichón, a 18 - 21 km de altitud, para examinar las características físicas y químicas de las partículas de ...
