Would it be somewhat accurate to think of a tornado as an upside-down "atmospheric volcano"?

Question

Thinking about why tornados form and how/why certain kinds of volcanos form, the processes for -certain- kinds of each can be similar. Tornados form the funnel when a storm cell starts spinning and one end of it sinks as the cool air from above mixes with it and "erupts" from the bottom of the tornado into the world below, the air spinning around as it does. Some kinds of volcanos form when a magma cell starts spinning and hotter magma from deeper within the earth pushes its way upwards, "erupting" through the resulting upside-down funnel.

It's not true of all volcanoes nor of all tornados, but _some_ seems to be similar phenomenon in different media. Is there any validity to this notion?

I know the differences, they're major. What I'm getting at now that I've had a moment to think about it: Can both (virtually all tornadoes and at least _some_ volcanoes) be considered the results of convection currents?

(Sorry I didn't state it that way right from the start - it just took a few moments for the right words to come to me)

Answer 1

hmmm, no,not really, how does a convection current form a volcano? most are formed when one continental plate or an ocean plate is going under another continental plate, or where two oceans plates are pulling apart from each other. this movement is from movement in the magma, not caused by convection but by the rotation of the earth itself.

some volcanoes are caused by a hot spot beneath the crust (hawaii for example) but still that is not convection.

basically i cannot see any similarities between the two.

Answer 2

I don't agree.volcanos erupt due to pressure from the inside earth.The magma comes out against gravity whereas funnel cloud in a tornado descend due to gravity.
Secondly, volcano contains only molten liquid thrown out generally in the form of a jet whereas tornado is made up of air,water vapour(gas) and water(liquid) with a whirling motion.
Thirdly, volcanos can form in any planet with a rocky formation and without atmosphere and tornados can form only in a planet or moon with an atmosphere.Particularly water source should be there for tornado formation.
Further tornado contains charged particles and thereby produce electricity in the form of lightning.So, there are many by-products from the tornado which are,lightning,thunder,rain and whirling wind whereas volcano produces only magma.

Answer 3

I'm not familiar with the idea that magma "spins" as it rises to the surface. You paint a very interesting picture, but I'm afraid it doesn't have much accuracy. Tornadoes and volcanoes are just TOO different for me to see any sort of a connection between how they're formed.

Answer 4

i don't think so. volcanoes help create land, and tornadoes destroy them. tornadoes form from the wind currents going in a counterclockwise motion creating a funnel. volcanoes have been here sincethe beginning of time because it takes so lond for them to form... tornadoes can form in an instant.

Answer 5

um no
