1963 winter and snow cover.

I doubt it, with Europe being relatively mild still, sea temperatures warmer and I suppose +1C for GW.

Loking at the current output one in a million might be more appropriate! Dave |

True (I'd actually say "a lot more" but I know what you meant), although December 2010 was a reminder that lengthy spells of severe cold can still occur. Loking at the current output one in a million might be more appropriate! Dave :) Though some notable winters (notably 1947) haven't begun till considerably later than this. And looking at that winter's charts for the first couple of weeks of January seemed to give no hint of what was to come. -- I'm not paid to implement the recognition of irony.

It does amuse me how on TWO board that they say we are approaching groundhog day for winter. Ridiculous, especially when, at least for me, we haven't had 4 weeks of winter yet! Not even thinking of Spring, neither is the garden.

December CET was 3.0C below 2014. As for minimum temperatures, December 1946 was 19= coldest in the full CET record, whilst Jan '47 was 25=. So 1946-7 was already a cold winter well before the February snowfall occurred. The frosty December and January would have gotten into the ground and, like the build-up to the 1962-3 winter, would have aided the persistence of the lying snow. -- Graham P Davis, Bracknell, Berks.

The CET average mean temperature for December was only +1.8C with average min of -1.1C (there have only been 10 Decembers with sub-zero mins since 1900). The ground was frozen hard before the snow fell and, at the time, we thought this was as least as important in maintaining the cold spell as the snow cover. I spent the first part of that winter on a farm on Dartmoor, and have contributed to Mike Tullet's website. You are right about the cold before the snow. It took us 8 hours to milk on the morning of Christmas Day, the clusters kept freezing. The clusters had to be taken apart in warm water and the rubber diaphragms replaced. The Boxing Day snow was only a couple of centimetres deep and was very fine and dry. When it started snowing on the 28th., we thought that it was only the fallen snow blowing about! The 'cowpats' in the yard were lifted with a mattock (like frisebies) and piled on the walls around the yard. They stayed there till the end of March - then there was a mess. Phil |

December CET was 3.0C below 2014. Oh yes, I'm certainly not trying to claim that we could see a repeat of 1947. As for minimum temperatures, December 1946 was 19= coldest in the full CET record, whilst Jan '47 was 25=. For January, that's largely because the real cold set in around the 23rd. So 1946-7 was already a cold winter well before the February snowfall occurred. The frosty December and January would have gotten into the ground and, like the build-up to the 1962-3 winter, would have aided the persistence of the lying snow. I don't think much frost would still have been in the ground when the main cold spell started, as there had been a mild spell from around the 8th to the 19th, with daily mean CETs of 3.3, 3.9, 2.9, 5.1, 5.9, 5.1, 6.7, 9.1, 10.0, 6.9, 6.3 and 2.8. Given that those are daily means rather than daily maxima, that is pretty mild. -- I'm not paid to implement the recognition of irony. (Taken, with the author's permission, from a LiveJournal post) |
