Preliminary estimate of the radiative and climatic effects of the El Chichon eruption

Geofísica Internacional, 1984
Se hizo una estimación preliminar del efecto climático de la mayor erupción volcánica de El Chichón en abril de 1982, utilizando una versión estacional de un modelo zonal de clima, considerando una capa oceánica de 70 m .

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, Volume 73, Issue 5, Page 1331-1351, August 2026.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Atmospheric impact of the volcanic eruptions of El Chichon over Mexico

Geofísica Internacional, 1984
En el presente trabajo reportarnos los efectos observados en la troposfera sobre el territorio mexicano después de las erupciones del volcán Chichón. En el estudio se utilizaron los registros de temperatura del aire de cinco observatorios, así como las ...

Reversal of the ITCZ Shift During the Satellite Era

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract A southward shift of the Intertropical Convergence Zone (ITCZ) during the latter half of the 20th century has been primarily attributed to interhemispheric differences in anthropogenic aerosol forcing. However, in recent decades anthropogenic aerosol emissions have declined, particularly over Northern Hemisphere (NH).

On the effect of the volcanic eruptions of Mount Agung and El Chichón on the temperature of the stratosphere

Geofísica Internacional, 1984
Durante el verano y el otoño de 1982, y también durante el verano y el otoño de 1963, la temperatura a 30 mbar subió más de tres desviaciones estándar sobre el promedio de 18 años en latitudes tropicales. Estos calentamientos se atribuyen a los aerosoles

Evaluating the simulated radiative forcings, aerosol properties, and stratospheric warmings from the 1963 Mt Agung, 1982 El Chichón, and 1991 Mt Pinatubo volcanic aerosol clouds [PDF]

Atmospheric Chemistry and Physics, 2020
Accurately quantifying volcanic impacts on climate is a key requirement for robust attribution of anthropogenic climate change. Here we use the Unified Model – United Kingdom Chemistry and Aerosol (UM-UKCA) composition–climate model to simulate the ...

Volcanic Forcing Amplifies Extreme Wet‐to‐Dry in Pre‐Flood South China Driven by Internal Variability

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Dry‐wet whiplash events profoundly impact society and the environment, yet their attribution remain poorly understood. This study reveals that the unprecedented interannual wet‐to‐dry transition (return period: 979.2 years) in South China's 1962–1963 pre‐flood season is co‐driven by internal variability and volcanic forcing.

Sulfur Exposure for Airplane Passengers From Stratospheric Aerosol Injection

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Injection of sulfur dioxide to create a stratospheric sulfate aerosol cloud is the most studied method of climate intervention. It has been suggested that airplanes be used at high latitudes to create such a cloud at lower altitudes. Commercial airplanes routinely fly at altitudes of 11 km in the Arctic, and therefore passengers could be ...

El Chichon's [PDF]

Geofísica Internacional, 2009
During one week (28 March-4 April 1982), three powerful explosive eruptions (VEI 5) of El Chichón Volcano caused the worst volcanic disaster in Mexico’s recorded history. Pyroclastic flows and surges obliterated nine villages, killing about 2,000 people,

Post‐Eruption Tropical Cyclone Genesis Potential Change Over the Western North Pacific Modulated by Initial Oceanic Conditions

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract How tropical cyclone (TC) frequency may change following volcanic eruptions remains debated, owing to limited contemporary eruption samples. Using last‐millennium multi‐member simulations with CESM, we show that post‐eruption TC genesis potential over the western North Pacific consistently decreases during the storm season following extremely ...
