The freezing cold spell in January 1987 brought
temperatures down to levels comparable with winter 1962/63, and with more snow, (below -20C so I've heard, and up to 30 inches of snow in the North Downs), but its effects were localised in the SE. Oh no they weren't! http://www.turnstone-cottage.co.uk/1987Snow.pdf Definitely not the SE. Graham Penzance |

I imagine it could have been devastating. Even in peace-time, the effects were very bad. The winters of 1940, 1941 and 1942 were cold, but fortunately not in that league. (I believe that at least one of those three winters was also exceptionally severe on the Russian front, even by that region's standards, and thus did the Allies a big favour in hampering the German invasion of Russia.) I have a vague memory of walking through 'canyons' in the snow in 1947 in Largs, North Ayrshire. Anecdotal evidence is that a blizzard in 1940 in Largs was more severe than anything in 1947. But how widespread was the blizzard in Largs? One factor which made the effects of winter 1947 so bad is that it affected a large percentage of the population. The freezing cold spell in January 1987 brought temperatures down to levels comparable with winter 1962/63, and with more snow, (below -20C so I've heard, and up to 30 inches of snow in the North Downs), but its effects were localised in the SE. The recent interest in winter 1947 has encouraged me to update the links page on my 'Winter 1947' website. Some links have gone since I first put it online. I've added others and obviously many more are out there waiting to be searched for. Appeals by the media on the 60th anniversary, in 2007, saw a lot of home cine film of 1947 snow and ice emerge. Some of this ended up on YouTube. http://www.swanstonweather.co.uk/Epp...s/wwwlinks.htm -- George in Swanston, Edinburgh, 580'asl www.swanstonweather.co.uk www.eppingweather.co.uk www.winter1947.co.uk |

Perhaps it would have been more accurate to say the worst effects were in the SE (nice photo btw). |

Severe weather in January 1940 affected much of the country, and it's perhaps fortunate that this was still (I think) the period of the "phoney war" and before the U-boats had French or Norwegian bases to operate from. I'm sure Trevor Harley won't mind me quoting his description of January 1940: 1940 The coldest month of any kind since 1895 (-1.4C CET), and eventually he second coldest January of the century (after 1963). The month started with a northerly airstream, but early in the month the winds turned to the east, bringing very cold continental air. It was clear and sunny, with hard frosts at night and several frost days. There was a severe blizzard on the 16th. On the 17th, the Thames was frozen over for the first time since 1880. The morning of the 21st gave the lowest temperature of the month: -23.3C was recorded at Rhayader (Wales), the record lowest Welsh minimum, with many places continuously well beneath freezing (e.g. only -4C maximum at Boscombe Down, Wilts.). There were heavy snowfalls in Scotland, with many places cut off. By the third week the Atlantic westerlies tried to return, bringing some heavy snowfalls. Most remarkably, there was a great snow and Ice Storm during the 27-30th, peaking on the 28th, but continuing in parts into February. Mild air approaching behind warm fronts from the SW met the cold easterly all the way from Russia. There was heavy snow over the north; four feet of snow in Sheffield on the 26th, and 10' drifts reported in Bolton on the 29th. Further south the lower air was warming up and was too warm for snow, but the rain froze as it fell, coating everything with a thick layer of glaze. The effects of the freezing rain was one of the most extreme weather events of the century. The south was particularly badly affected. Everything was coated in a thick layer of ice: phone wires 1.5 mm thick were coated with a 300mm diameter sheath of ice - up to 15 times their weight. Many large tree trunks and power lines were brought down. The area affected by the glaze reached from Kent to Exmoor and the Cotswolds, and from Sussex to Cambridgeshire and the north Midlands. It was a week before all the ice thawed; some places had snow on top of the glaze, with both remaining until the 4th February. Heavy snow and a violent gale swept the southwest. -- John Hall "One can certainly imagine the myriad of uses for a hand-held iguana maker" Hobbes (the tiger, not the philosopher!) |
