The reality is the UK is experiencing an exceptional cold spell, the
current CET is -2.0c, that is a whopping -7.6c below normal or, to put
it another way more than 4 Standard Deviations below the 1971-2009
normal of +4.8c. Someone with a maths degree should be able to
calculate the probabilty of this occuring. Philip Eden's CEThttp://www.climate-uk.com/

Also, there is a thread on TWO comparing this December with previous
December Central England Temperatures, worth a look.http://www.theweatheroutlook.com/two...spx?g=posts&t=...

So I make no appologies for talking about this current cold spell, and
suggesting that it may be a once in a liftime event, because I've
never experienced such a cold start to December/Winter in my 39 years
on this planet.

Not sure if I'm reading this correct, and it's from Wikipedia, but 3
Standard Deviations = 1 in 370 years, 4 Standard Deviations = 1 in
15,787 years, and 5 Standard Deviations = 1,744,277 years.

I've calculated the December mean from 1971 - 2009 as +5.0c, with a
Standard Deviation of 1.5c, so by my calculations the current CET that
is running at -2.0c is somewhere between 4 & 5 Standard Deviations.

I would be most grateful if someone could confirm?
