Detection of Satellite Sea Surface Temperature Extremes: Low Frequency Variability and Climate Change

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 10, October 2025.
Abstract The occurrence of sea surface temperature (SST) extremes may provoke profound impacts on ocean health. In the last decade, much effort has been dedicated to understanding and systematically describing marine heatwaves (MHWs) and cold spells (MCSs), defined as prolonged periods of anomalously warm or cold SSTs at a given location, respectively.

El Chichon's [PDF]

open access: yesGeofísica 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,

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.

Eruption Column Modeling of Explosive Volcanism on Venus

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Volcanism on Venus has never been directly observed, but several measurements indicate present‐day activity. Volcanism could potentially play a role in climatic processes on Venus, especially in the sulfur cycle like on Earth. Observation of volcanic activity is the primary objective of future Venus spacecraft. However, there are many unknowns

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.

The Impact of Natural External Forcing on Ocean Heat Uptake Efficiency Since the 1980s

open access: yesGeophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract We investigate the temporal evolution of ocean heat uptake efficiency (OHUE) using observations and large ensemble model simulations. OHUE, defined as the ratio of ocean heat uptake rate to changes in global mean surface temperature anomalies, has exhibited significant variability over recent decades. We found a relatively low OHUE in the late

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 ...

Impact of Sensible Heating and Water Vapor Emission on Pyro‐Convective Plume Characteristics

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 18, 28 September 2025.
Abstract PyroCb events are important sources of stratospheric aerosol. During the Australian forest fires in 2019/2020, such convective plumes transported quantities of smoke into the tropopause region comparable to those of a large volcanic eruption.

Multiple symptoms of total ozone recovery inside the Antarctic vortex during austral spring [PDF]

open access: yes, 2017
The long-term evolution of total ozone column inside the Antarctic polar vortex is investigated over the 1980-2016 period. Trend analyses are performed using a multilinear regression (MLR) model based on various proxies (heat flux, QBO, solar flux, AAO ...
