Bare snapshot af mange, der beskriver vejret i Europa. Under overskriften “Europas flytrafik sner fast” fortælles det fra England

Kun ganske få fly er i nat lettet fra Europas mest travle lufthavn Heathrow i London. Luftfartsselskabet British Airways advarer sine passagerer om, at de muligvis må droppe deres rejseplaner i julen.

Heathrow har advaret rejsende om, at de kan forvente kaos til efter juledag. En tredjedel af alle flyvninger forventes gennemført indtil i morgen tidlig.

Eksemplerne på at den kraftige sne har taget alt og alle med bukserne nede er der mange af i disse dage. Det manglende forsyn skyldes at f.eks. lufthavnen Heathrow har forladt sig på den førende autoritet i England udi vejr nemlig the Met Office, hvilket svarer til DMI i Danmark.Og hvilken autoritet er det ikke?

Met Office 2008 Forecast: Trend of Mild Winters Continues

Met Office, 25 September 2008: The Met Office forecast for the coming winter suggests it is, once again, likely to be milder than average. It is also likely that the coming winter will be drier than last year.

Reality Check: Winter of 2008/09 Coldest Winter For A Decade

Met Office, March 2009: Mean temperatures over the UK were 1.1 °C below the 1971-2000 average during December, 0.5 °C below average during January and 0.2 °C above average during February. The UK mean temperature for the winter was 3.2 °C, which is 0.5 °C below average, making it the coldest winter since 1996/97 (also 3.2 °C).

Met Office 2009 Forecast: Trend To Milder Winters To Continue, Snow And Frost Becoming Less Of A Feature

Met Office, 25 February 2009: Peter Stott, Climate Scientist at the Met Office, said: “Despite the cold winter this year, the trend to milder and wetter winters is expected to continue, with snow and frost becoming less of a feature in the future.

“The famously cold winter of 1962/63 is now expected to occur about once every 1,000 years or more, compared with approximately every 100 to 200 years before 1850.”

Reality Check: Winter Of 2009/10 Coldest Winter For Over 30 Years

Joeh, men hvem kan egentlig forudsige den slag? Det prøver Boris Johnson at svare på i Telegraph

Allow me to introduce readers to Piers Corbyn, meteorologist and brother of my old chum, bearded leftie MP Jeremy. Piers Corbyn works in an undistinguished office in Borough High Street. He has no telescope or supercomputer. Armed only with a laptop, huge quantities of publicly available data and a first-class degree in astrophysics, he gets it right again and again.

Back in November, when the Met Office was still doing its “mild winter” schtick, Corbyn said it would be the coldest for 100 years. Indeed, it was back in May that he first predicted a snowy December, and he put his own money on a white Christmas about a month before the Met Office made any such forecast. He said that the Met Office would be wrong about last year’s mythical “barbecue summer”, and he was vindicated. He was closer to the truth about last winter, too.

He seems to get it right about 85 per cent of the time and serious business people – notably in farming – are starting to invest in his forecasts. In the eyes of many punters, he puts the taxpayer-funded Met Office to shame. How on earth does he do it? He studies the Sun.

He looks at the flow of particles from the Sun, and how they interact with the upper atmosphere, especially air currents such as the jet stream, and he looks at how the Moon and other factors influence those streaming particles.

He takes a snapshot of what the Sun is doing at any given moment, and then he looks back at the record to see when it last did something similar. Then he checks what the weather was like on Earth at the time – and he makes a prophecy.

I have not a clue whether his methods are sound or not. But when so many of his forecasts seem to come true, and when he seems to be so consistently ahead of the Met Office, I feel I want to know more. Piers Corbyn believes that the last three winters could be the harbinger of a mini ice age that could be upon us by 2035, and that it could start to be colder than at any time in the last 200 years. He goes on to speculate that a genuine ice age might then settle in, since an ice age is now cyclically overdue.
