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

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.

A Multivariate Space‐Time Dynamic Model for Characterizing the Atmospheric Impacts Following the Mt. Pinatubo Eruption

Environmetrics, Volume 36, Issue 6, September 2025.
ABSTRACT The June 1991 Mt. Pinatubo eruption resulted in a massive increase of sulfate aerosols in the atmosphere, absorbing radiation and leading to global changes in surface and stratospheric temperatures. A volcanic eruption of this magnitude serves as a natural analog for stratospheric aerosol injection, a proposed solar radiation modification ...

Comparative Evaluation of Decadal Predictions of Global SST Between CMIP5 and CMIP6 Datasets

International Journal of Climatology, Volume 45, Issue 11, September 2025.
This study provides systematic evaluations of SST predictions across the North Pacific, North Atlantic, Indian Ocean, and tropical eastern Pacific were conducted using CMIP5 and CMIP6 datasets. While advancements in prediction accuracy were not prominently observed from CMIP5 to CMIP6 in the North Pacific and North Atlantic regions, significant ...

Combination of Internal Variability and Forced Response Reconciles Observed 2023–2024 Warming

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract The record‐breaking global mean surface temperature (GMST) in 2023 and 2024 came as a surprise to the scientific community, raising the question whether it provides evidence for a recent abrupt increase in the forced global warming rate. Here, we provide a new statistical learning‐based method to quantify the forced and internal variability ...

Chemical and isotopic study of thermal springs and gas discharges from Sierra de Chiapas, Mexico [PDF]

Geofísica Internacional, 2005
Thermal water and gas discharges south-east of El Chichón volcano, Mexico are associated mainly with NW-SE oriented fault systems. Spring discharges include i) waters with Na-Cl composition and TDS>3000 mg/L; ii) waters with Ca-SO4 composition and TDS ...

Roles of External Forcing and Internal Variability in Winter Precipitation Changes Over Central Asia

Earth's Future, Volume 13, Issue 7, July 2025.
Abstract Winter Central Asian precipitation (WCAP) is increasingly replacing snowfall as a critical water resource under global warming. Observations show a decline in WCAP from 1891 to 1946, followed by a recovery from 1947 to the recent decade. However, the relative contributions of external forcing and internal variability to these changes remain ...

Volcanic Radiative Power Retrieval From Moderate‐to‐Low‐Temperature Features Using a Single TIR Band: Validation Using Volcanic Crater Lakes and Hydrothermal Systems

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Assessing Radiative Power (RP) output is essential for monitoring and understanding volcanic systems. While Mid‐Infrared channels are used to assess thermal outputs at volcanoes exhibiting effusive activity, Thermal‐InfraRed (TIR) bands are better suited for measuring moderate‐to‐low‐temperature (≲600 K) features, such as those associated with

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

Inter‐eruptive lahars at El Chichón Volcano (Mexico): Susceptibility analysis and numerical modelling

Earth Surface Processes and Landforms, Volume 50, Issue 5, April 2025.
The Gumbel distribution allowed for defining rainfall scenarios and return periods, based on which rainfall‐runoff simulations were performed for each watershed draining from the volcano. The outflow hydrographs were used to simulate lahars from the main cone to the river system that bound the volcano.
