Black Hole Posted August 27, 2022 Report Share Posted August 27, 2022 Presumably most of you are aware of the volcanic eruption of Hunga Tonga a few months back. New research has shown that this volcano spewed an enormous amount of water vapor into the stratosphere. See Here. Apparently, the amount of water equaled about 10% of what was already up there. Water vapor in the stratosphere is known to warm the troposphere so there are discussions that this could induce some short term global warming for a few years, the opposite of what typically happens with volcanic eruptions. There is already satellite evidence suggesting that this is occurring. To take it a step further, I'm thinking about how it could effect global circulation next winter. I believe it is the case (Phil would know for sure) that a colder stratosphere should accompany a stronger polar vortex. So my question is, will this stronger polar vortex occur and how will it modify the la nina base state this year? Curious if anybody has any thoughts. 3 Quote Link to comment Share on other sites More sharing options...
