Discussion Overview

The discussion centers around unusual meteorological phenomena, specifically a "volcano tornado" observed above an Icelandic volcano, and comparisons to other tornado-like events such as firenadoes in bushfires. Participants explore the characteristics and similarities of these phenomena, as well as share personal experiences related to storm chasing.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants describe the "volcano tornado" as a slender vortex observed at high altitudes, likening it to a "fire tornado" and noting its classification by the Icelandic Met Office as "wind anomalies from thermal convection."
  • One participant shares that firenadoes are common in Australian bushfires and suggests that the formation of these phenomena may be similar to that of the volcano tornado.
  • Another participant introduces the concept of a supercell with two simultaneous tornadoes, discussing the characteristics of cyclonic and anticyclonic tornadoes and mentioning the occurrence of multiple vortices around a main tornado funnel.
  • There is a personal reflection on storm chasing experiences, with one participant expressing a desire to return to the USA for storm chasing, while noting the challenges of travel and health.

Areas of Agreement / Disagreement

Participants express interest in the phenomena discussed, but there is no consensus on the specifics of their formation or characteristics. Multiple competing views and personal experiences are shared without resolution.

Contextual Notes

Participants mention various meteorological phenomena without fully resolving the differences in their characteristics or formation processes. The discussion includes personal anecdotes that may influence perspectives.

Viewers will be amused at the slender vortex snaking 3300' above the Iceland volcano, seen here in infrared video. Said to be similar to a "fire tornado", the Icelandic Met Office officially refers to the strange phenomenon as "wind anomalies from thermal convection."

"We haven't seen anything like this before"

cool ! :)

don't think I have seen one related to a volcano before ... seen too many videos to remember haha

but these are quite common in bush fires we see here in Australia ... as commented, called firenadoes
I suspect the formation of them is very similar

cheers

Another meteorological curiosity - an amazing supercell with two simultaneous tornadoes. The one on the left is said anticyclonic, the one on the right cyclonic.

This phenomenal storm, with two tornadoes spinning simultaneously, was photographed late last week near Simla, Colo. (Kelly DeLay)

"I've never seen auroras and lightning visible side by side before," marvels Chester. "These photos were taken between 2 and 3 am on Monday, June 8th."

At about the same time in Hartford, Wisconsin, Jake Stehli witnessed a similar display. "The auroras were visible to the naked eye with lightning in a thunderhead on the horizon as well," he says.

awesome storm ... have 2 friends that have just got home to Oz from 3 weeks in the USA stormchasing. I just haven't had the money, health or available annual leave
to travel over there for the last few years :frown: I so miss my chase trips to the USA

twin and multi tornadoes for a single cell are common, not sure about the counter circulations tho ?
The other wild scenario is when a main tornado funnel starts producing multiple vortices around it that sometimes become large enough to be called a signif tornados in their own right ... then we have "sisters"

a pic from my chaser friend Reed Timmer ...

dunno who this one is from ?? ... would credit if I could ( not mine)

I expect the Australian ones go round the other way though.
