Hemispherically asymmetric volcanic forcing of tropical hydroclimate during the last millennium
Volcanic aerosols exert the most important natural radiative forcing of the last millennium. Stateof-the-art paleoclimate simulations of this interval are typically forced with diverse spatial patterns of volcanic forcing, leading to different responses in tropical hydroclimate. Recently, theoretical considerations relating the intertropical convergence zone (ITCZ) position to the demands of gl...
متن کاملDiscrepancies between themodeled and proxy-reconstructed response to volcanic forcing over the past millennium: Implications and possible mechanisms
[1] We show that a systematic discrepancy between model simulations and proxy reconstructions of hemispheric temperature changes over the past millennium appears to arise from a small number of radiatively large volcanic eruptions. Past work has shown that accounting for this mismatch alone appears to reconcile inconsistencies between the overall amplitude of simulated and proxy-reconstructed t...
متن کاملVolcanoes and ENSO over the Past Millennium
The controversial claim that El Niño events might be partially caused by radiative forcing due to volcanic aerosols is reassessed. Building on the work of Mann et al., estimates of volcanic forcing over the past millennium and a climate model of intermediate complexity are used to draw a diagram of El Niño likelihood as a function of the intensity of volcanic forcing. It is shown that in the co...
متن کاملInteractive comment on “ ENSO surface shortwave radiation forcing over the tropical Pacific
The paper "ENSO surface shortwave radiation forcing over the tropical Pacific" by Pavlakis et al adds the shortwave component to their earlier study, published in this journal, which examined ENSO surface longwave radiation forcing. The paper is fine, but the results basically corroborate previously published work regarding the evolution of ENSO induced changes in atmospheric circulation, outgo...
متن کاملComment on ‘‘Climate forcing by the volcanic eruption of Mount
[1] Douglass and Knox [2005, hereinafter referred to as DK], present an analysis of the observed tropospheric cooling following the 1991 Mt. Pinatubo eruption, and claim that these data imply a very low value for the climate sensitivity (equivalent to 0.6 C equilibrium warming for a CO2 doubling). We show here that their analysis is flawed and their results are incorrect. [2] We begin with a ve...
