What is a supercell tornado?

Some of the most violent tornadoes develop from supercell thunderstorms. A supercell thunderstorm is a long-lived thunderstorm possessing within its structure a continuously rotating updraft of air. These storms have the greatest tendency to produce tornadoes, some of the huge wedge shape. The supercell thunderstorm has a low-hanging, rotating layer of cloud known as a “wall cloud.” It looks somewhat like a layer of a layer cake that hangs below the broader cloud base. One side of the wall cloud is often rain-free, while the other is neighboured by dense shafts of rain. The rotating updraft of the supercell is seen on radar as a “mesocyclone.”
Clear as daylight isn't it!?

Tornado reported during storm in Oxfordshire
**taken from the BBC News website - no by-line was attached to this article in order to give proper credit to the author - Mr I**
A tornado has been reported in parts of Oxfordshire during a storm which caused damage to trees and roof tiles. It was spotted in several places, including Bicester, Eynsham, Kidlington and South Leigh, on Monday afternoon.

Large hailstones were also reported during the storm, which is thought to have started in Wiltshire and moved to Oxfordshire and Buckinghamshire.One forecaster said it was almost certainly a tornado, thought to have been caused by a special kind of storm. Brendan Jones, from Meteogroup, said: "At the moment it's difficult to say exactly where the tornado was because while the parent thunderstorm travelled all the way across the south Midlands, it wasn't necessarily producing a tornado all the time.
"There has been more than one report of a tornado beneath this storm. There has also been some quite big hailstones." He said it was likely the storm was a "supercell"
thunderstorm, when the air spins or rotates, which is not often seen in
the UK.
Eyewitness Dave Ewart, from Kidlington, said: "I was at home when I noticed heavy dark clouds forming, then hail then - very suddenly - extremely high winds. "I saw my car bouncing up and down on its suspension - which is very unusual. And then we spotted spinning clouds."
Richard Glazer, 40, drove through it with his wife and son on the A34 near Kidlington.
He said: "It was very wet, we were just driving on the A34 and looked up and realised one part of the sky was moving in one direction and another in the opposite direction. "I thought, 'that looks like a tornado'. We pretty much drove through it, we were right underneath it. "As we drove into it the trees were blowing left to right and as we got through it they were blowing the other way."
Jo Cotterill, from Kidlington, said: "At about 4pm this afternoon we had a freak hailstorm, lasting about two minutes, along with massive gusts of wind that damaged street lights, roof tiles and trees."

An apology........
Dear all,
I feel an apology is overdue. I have been terribly remiss in not updating the blog more regularly over the last few months. No real excuse save for wedding planning and the usual workload of a teacher in the build up to exams. I am however, back to the blog and will be posting more articles in the coming days and weeks.
Things to look out for:
Year 7 - posts regarding ecosystems and settlements
Year 9 - posts relating to our new unit on the Geography of Crime
A-Level - extra reading/interest bits on Conflict, Population dynamics, Health and Development
So...not much then...
Right, back to blogging with some local news.
