Tornadoes don't form the way scientists thought

[Still Waters]

Historically, tornadoes have been thought to originate in the clouds, reaching turbulent fingers down to Earth. But now a team of climatologists has demonstrated that this 'top-down' model of tornadogenesis might actually be wrong.

Yep. Tornadoes, their research has found, form from the ground up.

Tornadoes can form surprisingly quickly, in just a couple minutes. That's why capturing the birth of one isn't exactly easy, especially near the ground where trees and houses can get in the way. Still, meteorologist Jana Houser from Ohio University has been chasing them for years.

Wow.. that IS interesting. 

I guess it's like lightening; that starts from the ground and goes upwards as well, before the electron stream comes back down again.
