Modeling Volcanic Eruption Parameters by Near-Source Internal Gravity Waves
Volcanic explosions release large amounts of hot gas and ash into the atmosphere to form plumes rising several kilometers above eruptive vents, which can pose serious risk on human health and aviation also at several thousands of kilometers from the volcanic source. However the most sophisticate atmospheric models and eruptive plume dynamics require input parameters such as duration of the ejec...
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...
متن کاملClimate forcing by the volcanic eruption of Mount Pinatubo
[1] We determine the volcano climate sensitivity l and response time t 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. Using standard linear response theory we find l = 0.15 ± 0.06 K/(W/m), which implies a negative feedback of 1.4 (+0.7, 1.6...
متن کاملVolcanic Tremor and Its Use in Estimating Eruption Parameters
Volcanic tremor, a continuous seismic signal, accompanies virtually all eruptions. Several published studies have examined relations between tremor reduced displacement (DR, a normalized amplitude measure) and the VEI or ash plume height. The goals of these studies are to determine the physical relationships between tremor and eruptions and to use DR values to provide real-time estimates of eru...
