On the dependency of simulated volcanically-forced variability to model configuration
2020<p>Several uncertainties affect the simulation of the climatic response to strong volcanic forcing by coupled climate models, which primarily stem from model specificities and intrinsic variability. To better understand the relative contribution of both sources of uncertainties, the Model Intercomparison Project on the climatic ...

Volcanic forcing of oxygenation dynamics in the mid-Proterozoic
Large Igneous Province (LIP) volcanism is commonly considered to have driven ocean deoxygenation and associated mass extinctions during the Phanerozoic. However, the impacts and feedback mechanisms associated with LIP emplacement in the prevailingly low-oxygen Precambrian environment remain poorly understood.Longfei Sun +11 more

Saturation in forcing efficiency and temperature response of large volcanic eruptions
Journal of Geophysical Research: AtmospheresWe investigate the climatic effects of volcanic eruptions spanning from Mt.\ Pinatubo-sized events to super-volcanoes. The study is based on ensemble simulations in the Community Earth System Model Version 2 (CESM2) climate model using the Whole Atmosphere Community Climate Model Version 6 (WACCM6) atmosphere model.

Radiative forcing by volcanic aerosols from 1850 to 1994
Journal of Geophysical Research: Atmospheres, 1999We use our detailed radiative transfer model and the latitude‐altitude distributions of zonal mean optical properties for the Pinatubo aerosol to calculate the time evolution of its instantaneous radiative forcing. We represent the zonal mean of this radiative forcing in terms of the zonal mean optical depth of the Pinatubo aerosol, together with the ...

Sensitivity of Monsoon Onset to Idealised Volcanic Forcing
Large volcanic eruptions are a source of climate variability, affecting global temperatures and precipitation. The hydrology of the Indian monsoon region is particularly sensitive to volcanic forcing. Previous studies have focused on the seasonal mean response of the Indian monsoon to eruptions.Shreyas Iyer +3 more

Anomalous atmospheric circulations forced by volcanic aerosols
2009During a strong volcanic eruption, the energy balance of the Earth is temporarily disturbed due to the addition of sulphate aerosols to the stratosphere. The selective absorption and reflection of radiation by these aerosols lead to both radiative and thermodynamical effects in the atmosphere.

Solar, volcanic, and CO2 forcing of recent climatic changes
Climatic Change, 1982The climate, as represented by the mean Northern Hemisphere temperature, has shown substantial changes within the past century. The temperature record is utilized as a means of elucidating the relative importance of anthropogenic CO2 increase, volcanic aerosols, and possible solar insolation variations in externally forcing climate changes.
