Atmospheric and Deposition Responses of 10Be to Volcanic Eruptions Inferred From the Aerosol‐Climate Model ECHAM6.3‐HAM2.3‐SALSA2.0: 10Be

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract 10Be deposition in ice cores is widely used for solar reconstructions, but its interpretation is complicated by volcanic influences. Using the state‐of‐the‐art aerosol‐climate model ECHAM6.3‐HAM2.3‐SALSA2.0: 10Be, we assess the impacts of three major volcanic eruptions: Agung (1963), El Chichón (1982) and Pinatubo (1991). All eruptions enhance

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 ...

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

Geophysical 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

The 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

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

Journal 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.

Eruption Column Modeling of Explosive Volcanism on Venus

Journal 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

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

Geophysical 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

MAJOR AND TRACE ELEMENT GEOCHEMISTRY OF EL CHICHON VOLCANO-HYDROTHERMAL SYSTEM (CHIAPAS, MEXICO) IN 2006-20078: IMPLICATIONS FOR FUTURE GEOCHEMICAL MONITORING [PDF]

Geofísica Internacional, 2009
Isotopic, major and trace element composition studies for the crater lake, the Soap Pool and thermal springs at El Chichón volcano in November 2006-October 2007 confirm the complex relationship between annual rain-fall distribution and crater lake volume

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

Journal 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.
