Impact of volcanic eruptions on CMIP6 decadal predictions: a multi-model analysis [PDF]

Earth System Dynamics
In recent decades, three major volcanic eruptions of different intensity have occurred (Mount Agung in 1963, El Chichón in 1982 and Mount Pinatubo in 1991), with reported climate impacts on seasonal to decadal timescales that could have been potentially ...

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

Journal 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

Small influence of solar variability on climate over the past millennium [PDF]

, 2014
The climate of the past millennium was marked by substantial decadal and centennial scale variability in the Northern Hemisphere(1). Low solar activity has been linked to cooling during the Little Ice Age (AD 1450-1850; ref.

Modeling the distribution of the volcanic aerosol cloud from the 1783–1784 Laki eruption [PDF]

, 2006
We conducted simulations of the atmospheric transformation and transport of the emissions of the 1783–1784 Laki basaltic flood lava eruption (64.10°N, 17.15°W) using the NASA Goddard Institute for Space Studies modelE climate model coupled to a sulfur ...

Enhanced Global Monsoon in Present Warm Period Due to Natural and Anthropogenic Forcings

Atmosphere, 2018
In this study, we investigate global monsoon precipitation (GMP) changes between the Present Warm Period (PWP, 1900–2000) and the Little Ice Age (LIA, 1250–1850) by performing millennium sensitivity simulations using the Community Earth System Model ...

Climate Sensitivity to Volcanic Aerosol Forcing

, 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.

Strong responses of Southern Ocean phytoplankton communities to volcanic ash [PDF]

, 2014
Volcanic eruptions have been hypothesized as an iron supply mechanism for phytoplankton blooms; however, little direct evidence of stimulatory responses has been obtained in the field.

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.

Easy Volcanic Aerosol (EVA v1.0): an idealized forcing generator for climate simulations [PDF]

Geoscientific Model Development, 2016
Stratospheric sulfate aerosols from volcanic eruptions have a significant impact on the Earth's climate. To include the effects of volcanic eruptions in climate model simulations, the Easy Volcanic Aerosol (EVA) forcing generator provides ...
