Eruption column with stratospheric injection
WebThe ascending, vertical part of the mass of erupting debris and volcanic gas that rises directly above a volcanic vent. Higher in the atmosphere, columns usually spread laterally into plumes or umbrella clouds. A cloud of tephra and gases that forms downwind of an erupting volcano is called an eruption cloud. WebJun 14, 2024 · It highlights the need to include volcanic halogen emissions when simulating the climate impacts of past or future eruptions, as well as the necessity to maintain space-borne observations of stratospheric compounds to better constrain the stratospheric injection estimates of volcanic eruptions.

WebMay 21, 1993 · Hydrogen chloride (HCl) scavenging processes during the early phases of a volcanic eruption are discussed. A plume dynamics and thermodynamics model is used to show that HCl removal in condensed supercooled water can reduce HCl vapor concentrations by up to four orders of magnitude, preventing substantial stratospheric … WebAug 31, 2024 · To affect global climate, an eruption must inject large quantities of sulfur dioxide (SO 2) or other sulfur species (e.g., hydrogen sulfide, H 2 S) into the stratosphere, where they are converted...
WebSep 22, 2024 · Large volcanic eruptions, although rare events, can influence the chemistry and the dynamics of the stratosphere for several years after the eruption. Here we show that the eruption of the submarine volcano Hunga Tonga-Hunga Ha’apai on 15 January 2024 injected at least 50 teragrams of water vapor directly into the stratosphere. http://large.stanford.edu/courses/2024/ph240/mueller2/
WebJan 18, 2024 · Under the assumption of an extratropical source, the stratospheric sulfur injection of the eruption is estimated to be 10.6 Tg S (Toohey and Sigl, 2024), which would be the fifth largest injection from an extratropical NH eruption over the same time span, comparable to the upper range of estimates for the 1912 Katmai eruption (Stothers, … WebThe 1257 CE eruption of Mount Samalas (Indonesia) is the source of the largest stratospheric injection of volcanic gases in the Common Era. Sulfur dioxide emissions produced sulfate aerosols that cooled Earth’s climate with a range of impacts on society.
