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.

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

Geofísica 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 ...

Long-term variations and trends in the simulation of the middle atmosphere 1980–2004 by the chemistry-climate model of the Meteorological Research Institute [PDF]

, 2008
A middle-atmosphere simulation of the past 25 years (from 1980 to 2004) has been performed with a chemistry-climate model (CCM) of the Meteorological Research Institute (MRI) under observed forcings of sea-surface temperature, greenhouse gases, halogens,

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 ...

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 ...

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

The sensitivity of EC-Earth3 decadal predictions to the choice of volcanic forcing dataset: insights for the next major eruption [PDF]

Geoscientific Model Development
Large volcanic eruptions can have significant impacts on climate. Due to their unpredictable nature, when a major volcanic eruption occurs, decadal forecasts issued prior to the eruption will be inaccurate.

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

, 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 ...
