Lee Ann Grimm and Oklahoma Tornado

Many tornadoes have swept through the United States in the last century, but one of the largest devastated El Reno, Oklahoma( located near Oklahoma City), on May 31, 2013.

The tornado was a top of the scale EF5 with winds reaching 295mph.  It measured 2.6 miles in width and 16.2 miles long which is recorded as the largest in history.  It took only a mere 40 minutes to kill at least 18 people.  The last record was 2.5 miles in width that hit Hal lam, Nebraska.

The tornado that hit El Reno was described as, "A huge funnel, made up of multiple smaller tornadoes rotating like horses around a merry-go- round."

Questions are being asked??????

What controls the intensity of a tornado?
Is there a particular balance of elements that are necessary for such a large tornado to form?
What particular areas and regions are tornadoes attracted to?
