Historical Simulations With HadGEM3‐GC3.1 for CMIP6

open access: yesJournal of Advances in Modeling Earth Systems, 2020
We describe and evaluate historical simulations which use the third Hadley Centre Global Environment Model in the Global Coupled configuration 3.1 (HadGEM3‐GC3.1) and which form part of the UK's contribution to the sixth Coupled Model Intercomparison ...

Origin of spurious single forces in the source mechanism of volcanic seismicity [PDF]

open access: yesJournal of Volcanology and Geothermal Research, 2013
Single forces are often observed in the source mechanism of volcanic seismicity. However, their underlying causative processes are still doubtful. The reliability of single force observations must be assessed, prior to analyzing them in terms of physical mechanisms. Using numerical examples, we show that source mislocation and velocity mismodeling lead

Solar and volcanic forcing of North Atlantic climate inferred from a process-based reconstruction [PDF]

open access: yesClimate of the Past, 2018
The effect of external forcings on atmospheric circulation is debated. Due to the short observational period, the analysis of the role of external forcings is hampered, making it difficult to assess the sensitivity of atmospheric circulation to ...

Climate Sensitivity to Volcanic Aerosol Forcing

open access: yes, 2022
Volcanic aerosol forcing has been reported in the literature to be less effective in changing the earth’s surface temperature than CO2 forcing. This implies a different feedback strength, and therefore different contributions from individual feedback mechanisms.

Holocene glacier variations and their potential orbital, solar, volcanic and anthropogenic forcings

open access: yesЛëд и снег, 2015
The magnitude of glacier advances generally increased in the Northern Hemisphere and decreased in the Southern Hemisphere over the Holocene. This trend can be explained be the orbital forcings. The exceptions are in some regions of the high Asia. 10–4 ka

Anthropogenic influence on the changing risk of heat waves over India

open access: yesScientific Reports, 2022
The overarching goal of this paper is to shed light on the human influence on the changing patterns of heat waves in India using the Heat Wave Magnitude Index daily (HWMId).

ModE-Sim – a medium-sized atmospheric general circulation model (AGCM) ensemble to study climate variability during the modern era (1420 to 2009) [PDF]

open access: yesGeoscientific Model Development, 2023
We introduce ModE-Sim (Modern Era SIMulations), a medium-sized ensemble of simulations with the atmospheric general circulation model ECHAM6 in its LR (low-resolution) version (T63; approx. 1.8∘ horizontal grid width with 47 vertical levels).

Climate Response to Pulse Versus Sustained Stratospheric Aerosol Forcing

open access: yesGeophysical Research Letters, 2019
Solar geoengineering has been suggested as a potential means to counteract anthropogenic warming. Major volcanic eruptions have been used as natural analogues to large‐scale deployments of stratospheric aerosol geoengineering, yet difference in climate ...

Climate forcing by the volcanic eruption of Mount Pinatubo [PDF]

open access: yesGeophysical Research Letters, 2005
We determine the volcano climate sensitivity λ and response time τ for the Mount Pinatubo eruption, using observational measurements of the temperature anomalies of the lower troposphere, measurements of the long wave outgoing radiation, and the aerosol optical density.

Long-term variability of drought indices in the Czech Lands and effects of external forcings and large-scale climate variability modes [PDF]

open access: yesClimate of the Past, 2019
While a considerable number of records document the temporal variability of droughts for central Europe, the understanding of its underlying causes remains limited.
