Impacts of initial conditions on volcanic forcing and responses

2023
Volcanic impacts on the environment and climate depend on the volcanic forcing. This is controlled by the eruption source parameters like eruption magnitude, composition, season, latitude and injection altitude. But how the volcanic forcing is affected by initial conditions, and what differences tropical and extratropical volcanic eruptions have is not

No consistent ENSO response to volcanic forcing over the last millennium

Science, 2020
Not a big deal after all Do volcanic eruptions affect El Niño–Southern Oscillation (ENSO) variability? Models indicate that sulfate aerosols resulting from large eruptions can initiate an El Niño–like response in the tropical Pacific, but observations have not shown evidence of such behavior.

Periodicity and driving forces of volcanism

Russian Geology and Geophysics, 2015
Abstract The volume and style of volcanism change periodically, with cycles of three main scales, which have different causes and effects. Short cycles of volcanic activity last from tens to thousands of years and are associated with periodic accumulation of magma in shallow chambers and its subsequent eruptions.

Non-parametric estimation of temperature response to volcanic forcing

Journal of Geophysical Research: Atmospheres
Large volcanic eruptions strongly influence the internal variability of the climate system. Reliable estimates of the volcanic eruption response as simulated by climate models are needed to reconstruct past climate variability. Yet, the ability of models to represent the response to both single-eruption events and a combination of eruptions remain ...

Proxy evidence for an El Niño-like response to volcanic forcing

Nature, 2003
Past studies have suggested a statistical connection between explosive volcanic eruptions and subsequent El Niño climate events. This connection, however, has remained controversial. Here we present support for a response of the El Niño/Southern Oscillation (ENSO) phenomenon to forcing from explosive volcanism by using two different palaeoclimate ...

An Energy Transport View of ENSO Responses to Volcanic Forcing

2023
El Niño-Southern Oscillation (ENSO) is one of the major climate phenomena impacting the globe. When a volcanic eruption happens, how ENSO will respond has still no consensus in proxy data though climate models tend to have an El Niño tendency.

Drag force simulation in explosive volcanic flows

AIP Conference Proceedings, 2015
This paper focuses on the interphase drag force simulation of volcanic flows by means of mixture formulation with velocity nonequilibrium. Numerical simulations are performed on a volcanic gas-ash mixture collision and the influence of the drag force is verified on a number of cases.

Exciting natural modes of variability by solar and volcanic forcing: idealized and realistic experiments

Climate Dynamics, 2004
Using multi-millenium simulations performed with the three-dimensional climate model ECBILTCLIO, we analyze how variations in the external forcing can excite low-frequency modes of climate variability. We find that prescribing an idealized, abrupt decrease in solar irradiance can trigger a large perturbation of the oceanic thermohaline circulation (THC)
