Evidence for changes in stratospheric transport and mixing over the past three decades based on multiple data sets and tropical leaky pipe analysis [PDF]

, 2010
Variability in the strength of the stratospheric Lagrangian mean meridional or Brewer-Dobson circulation and horizontal mixing into the tropics over the past three decades are examined using observations of stratospheric mean age of air and ozone. We use

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.

Excitation of atmospheric oscillations by volcanic eruptions [PDF]

, 1994
We investigated the mechanism of atmospheric oscillations with periods of about 300 s which were observed for the 1991 Pinatubo and the 1982 El Chichón eruptions.

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 ...

The global warming hiatus: Slowdown or redistribution? [PDF]

, 2016
Global mean surface temperatures (GMST) exhibited a smaller rate of warming during 1998-2013, compared to the warming in the latter half of the 20th Century.

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 ...

Atmospheric extinction coefficients in the $\mathrm{I_c}$ band for several major international observatories: Results from the BiSON telescopes, 1984 to 2016 [PDF]

, 2017
Over 30 years of solar data have been acquired by the Birmingham Solar Oscillations Network (BiSON), an international network of telescopes used to study oscillations of the Sun. Five of the six BiSON telescopes are located at major observatories.
