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

open access: yesAtmosphere, 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.

Manufacturing Consent: Faragism and the Hegemonic Struggle for Britain

open access: yesSociology 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

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

open access: yesGeofísica 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.

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

open access: yesGeophysical 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.

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

open access: yesGeofísica 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 ...

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

open access: yesGeophysical 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 ...

Independent Short‐ and Longwave Pathways for a Zonally Asymmetric Northern Hemisphere Temperature Response to Tropical Volcanic Eruptions

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Stratospheric sulfate aerosols from tropical volcanic eruptions alter surface air temperatures. Fundamentally, this is due to two different properties of the aerosols: Their ability to reflect incoming solar shortwave radiation, and their ability to absorb terrestrial longwave radiation.

Late Pleistocene to Holocene sedimentation in the Great Blue Hole (Lighthouse Reef, Belize): Results from a 30 m long core

open access: yesThe Depositional Record, Volume 11, Issue 5, Page 1376-1398, November 2025.
A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

Temporal variations in characteristics of the El Chichón stratospheric cloud

open access: yesGeofísica 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 ...
