    I have decided to use todays average winter CET of 4.5C and compare it against winter CET's since 1660.

    I will class the winters into several catergories, these are:

    Severe - 3C or less

    Cold - 3C to 4C

    Average - 4C to 5C

    Mild - 5C to 6C

    Hot - 5C or above

    What months do you define your winter CET averages? I

    I take it you don't do December because if you did the 1963 CET for example would be 1962/63

    The figures suggest to me that December to February is indeed being used. Winter 1962-63, for example, is defined as winter 1963.

    i think the way you have classified those winters are misleading.

    should be:

    6c and over = very mild

    5c-6c = mild

    4-5c = average

    3-4c = rather cold

    2-3c = cold

    below 2c = severe

    plus the average for 1971-2000 which i assuming you are using would certainly not been average pre 20th century and would have been classed as mild..IMO.

    Yes, i use the average CET of 4.5C so i can compare how cold past winters were, as opposed to this one, and i have no choice but to classify anything less than 3C as severe as the official definition of a severe winter is a winter with a CET of less than 3C.

    i dont agree about the definition of a severe winter...simply because the defintion of a severe winter month is one with a cet of below 2c..therefore by your thinking you could have severe winter winter with no severe months in it!

    Hmm, I was always under the impression that the metoffice defined a severe winter as 3°C below average and not an actual value of 3°C.

    The metoffice also use the 1961-1990 average still, which makes a 3°C CET winter being severe unlikely as the "average" is only 4.20°C.

    If the Met Office definition of a sever winter was a winter with a CET which was 3C below the 1961-1990 average of 4.2C, then the winter of 1979 would not have been classed as sever because that had a CET of 1.6C.

    I am correct.

    It turns out that everybody else is right, the official definition of a severe winter is a winter with a CET 3C below average therefore, a winter must have an average CET of 1.5C or less in order to be categorised as severe.

    The Met Office link is here:

    http://www.metoffice.com/weather/europe/uk/guide.html

    However, I presume those definitions refer to daily temps rather than seasonal averages? Or perhaps they do. I think we should probably try to stick to official designations from organisations such as the Met Office rather than esoteric sources. I don't think 'severe' is in their metereological designation. 'Well below' is about as far as it goes I think?

    Just reading through, i had forgotten about this thread, and i think i will do the rest of the winter CET averages that i have missed out, in the future i may also do the same for different seasons, i will also update the definitions.

    Also reading through, i am suprised at how arrogant i came across in the early stages of this thread.
