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

Met Office, 1 March 2010: Provisional figures from the Met Office show that the UK winter has been the coldest since 1978/79. The mean UK temperature was 1.5 °C, the lowest since 1978/79 when it was 1.2 °C.

Met Office July 2010: Climate Change Gradually But Steadily Reducing Probability Of Severe Winters In The UK

Ross Clark, Daily Express, 3 December 2010: ONE of the first tasks for the team conducting the Department for Transport’s “urgent review” into the inability of our transport system to cope with snow and ice will be to interview the cocky public figure who assured breakfast TV viewers last month that “I am pretty confident we will be OK” at keeping Britain moving this winter. They were uttered by Transport secretary Philip Hammond himself, who just a fortnight later is already being forced to eat humble pie… If you want a laugh I recommend reading the Resilience Of England’s Transport Systems In Winter, an interim report by the DfT published last July. It is shockingly complacent. Rather than look for solutions to snow-induced gridlock the authors seem intent on avoiding the issue. The Met Office assured them “the effect of climate change is to gradually but steadily reduce the probability of severe winters in the UK”.

Met Office 2010 Forecast: Winter To Be Mild Predicts Met Office

Daily Express, 28 October 2010: IT’S a prediction that means this may be time to dig out the snow chains and thermal underwear. The Met Office, using data generated by a £33million supercomputer, claims Britain can stop worrying about a big freeze this year because we could be in for a milder winter than in past years… The new figures, which show a 60 per cent to 80 per cent chance of warmer-than-average temperatures this winter, were ridiculed last night by independent forecasters. The latest data comes in the form of a December to February temperature map on the Met Office’s website.

Reality Check: December 2010 “Almost Certain” To Be Coldest Since Records Began

The Independent, 18 December 2010: December 2010 is “almost certain” to be the coldest since records began in 1910, according to the Met Office.

Met Office Predicted A Warm Winter. Cheers Guys

John Walsh, The Independent, 19 January 2010: Some climatologists hint that the Office’s problem is political; its computer model of future weather behaviour habitually feeds in government-backed assumptions about climate change that aren’t borne out by the facts. To the Met Office, the weather’s always warmer than it really is, because it’s expecting it to be, because it expects climate change to wreak its stealthy havoc. If it really has had its thumb on the scales for the last decade, I’m afraid it deserves to be shown the door.

A Frozen Britain Turns The Heat Up On The Met Office

Paul Hudson, BBC Weather, 9 January 2010: Which begs other, rather important questions. Could the model, seemingly with an inability to predict colder seasons, have developed a warm bias, after such a long period of milder than average years? Experts I have spoken to tell me that this certainly is possible with such computer models. And if this is the case, what are the implications for the Hadley centre’s predictions for future global temperatures? Could they be affected by such a warm bias? If global temperatures were to fall in years to come would the computer model be capable of forecasting this?

A Period Of Humility And Silence Would Be Best For Met Office

Dominic Lawson, The Sunday Times, 10 January 2010: A period of humility and even silence would be particularly welcome from the Met Office, our leading institutional advocate of the perils of man-made global warming, which had promised a “barbecue summer” in 2009 and one of the “warmest winters on record”. In fact, the Met still asserts we are in the midst of an unusually warm winter — as one of its staffers sniffily protested in an internet posting to a newspaper last week: “This will be the warmest winter in living memory, the data has already been recorded. For your information, we take the highest 15 readings between November and March and then produce an average. As November was a very seasonally warm month, then all the data will come from those readings.”

In the heading, if the Met Office is singular and present then the verb should be “misleads”. If in the past, “misled”.

What?
“This will be the warmest winter in living memory, the data has already been recorded.”
Already recorded, at least now they are admitting that they make up the numbers as needed !

Why are data not in chronological order?
On this side of the pond – Costa Rica – I am accustomed to apparent chance/random recitations. However, I have come to depend on WUWT for orderly accounts.

Look people, you have to understand that the temps outside your front doors are simply raw (data), and will not be accurate until adjusted and homogenized. Next summer after everyone forgets how cold it is, the Met will discover some heat that ya’ll are missing now and it will turn out that this winter is not nearly as cold as you are experiencing…

A period of humility and even silence would be particularly welcome from the Met Office. No, no, no. I want to hear all their predictions, every single detail and them explain the minor difference was cause by the Y2K bug or Wikileaks.

The mixing of (expensive giga) gifts, politics and science, better rather naive scientists will always end up as bad news for science.

December 20, 2010 9:23 am

it only makes sense, if you are trying to measure the “warmest winter” then taking the top 15 measurements over the course of 150 days of winter makes sense … of course if you are looking for the “coldest winter”, then taking the fifteen lowest measurements would also make sense … seems like you could have both the warmest and coldest winter in the same year which of course tells us nothing about the average … thats some solid scientific method you’ve got there …

I really hate it when misleading stats are used by the anti-AGW brigade in the same way that the warmista do.
Example:
“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
Since 30 years before 2009 means “since 1979”, there is nothing about these two statements that is contradictory, so why is this labelled “Reality Check”?

What is wrong with the Met office?
They make the available evidence fit the CONJECTURE, rather than allowing the evidence to form a proposition.
This method is that favoured by TV magicians and dubious salesmen

P Wilson
December 20, 2010 9:26 am

That should be added to – the evidence is also exaggerated to fit the conjecture

You’re re-reporting something that’s becoming a bit of an urban myth there. The quote that Dominic Lawson repeated was from a comment to a blog and didn’t come from the Met Office. That’s not the way they work out seasonal averages at all, but the myth seems to be developing a life of its own.
[ryanm: yes, this one has triggered my bull-crap meter. Dominic replied to my email asking where he found that quote. He said he didn’t remember. Sigh.]

The Met *staffer* ought to be informed that December, January and February are winter months. November is still an autumn month.

OK….there are a couple things in this article that confuse me. the following is at the core of my confusion:
“This will be the warmest winter in living memory, the data has already been recorded. For your information, we take the highest 15 readings between November and March and then produce an average.”
1) The data has already been recorded and yet in the next sentence it’s stated the readings take place between November and March. It is currently still December so how can the numbers be recorded for 3 months that haven’t even happened yet?
2) They produce an average based on the highest 15 reading between November and March. So they base everything from 15 readings over a period of 5 months? And they only look at the highest readings? No wonder they call it the hottest ever when they completely ignore the cold temperatures like they don’t exist.
If I have read the article wrong please let me know and help relieve my confusion.

Yes, Let’s hear the Met Office predictions and the explanation how they got it so wrong. If I turned in work of this quality, I’d be sacked but the higher up the pay scale you go, responsibility matters less. This is what’s wrong with our country wether it be defence spending, transport, social services or weather forecasting. Time to get sacking – gross incompetence – your fired! (Apologies to the AGW cultists).

““This will be the warmest winter in living memory, the data has already been recorded. For your information, we take the highest 15 readings between November and March and then produce an average. As November was a very seasonally warm month, then all the data will come from those readings.”
It would be nice if the above absurdity could be confirmed as a real Met Office staffer and not someone being malicious, because WOW…that is a pretty huge mozza ball hanging there. It wouldn’t surprise me if that is truly how they determine their average…..but to actually spill that can of worms seems almost too good to be true.

And what is most bothersome, is that they never ask themselves why they are consistently wrong in this regard.

“This will be the warmest winter in living memory, the data has already been recorded. For your information, we take the highest 15 readings between November and March and then produce an average. As November was a very seasonally warm month, then all the data will come from those readings.”
Last time I looked at a calendar November was still in the Fall, not the Winter. Has global warming changed that?

“This will be the warmest winter in living memory, the data has already been recorded.”
I’m sorry; I have to be misreading this – are we at the point of climate by dictate now?
The method described, taking the highest 15 temps between November and March and averaging them, does not seem to be a sound way of determine the average temperature of winter. Why not just average all the data in the winter months? Why they counting using November and March data when in the UK (according to wikipedia) winter is defined by meteorologists as December, January, and February?
These people are criminal.

I’m still impressed that Piers Corbyn is able to predict the MET office forecasts, before the MET office cooks them up ,sorry, publishes them:
“Standard meteorology will consistently underestimate the lengths of cold periods and will grossly underestimate the severity of blizzard and snow deluges at times.”
(From: http://www.weatheraction.com/docs/WANews10No37.pdf)
Piers also predicts the weather better than the MET office. Admittedly that particular bar is not set very high, but credit where credit is due.
Meanwhile ‘Prof’ Julia Slingo indicated to the UK parliament that the climate models must be correct, because they share code with the MET office weather prediction program…
“At least for the UK the codes that underpin our climate change projections are the same codes that we use to make our daily weather forecasts, so we test those codes twice a day for robustness”
(see http://www.publications.parliament.uk/pa/cm200910/cmselect/cmsctech/387b/38724.htm)
There you have it: buffoonery and talent – and where does the UK government go for advice?!

Exactly, you beat me to it!
Another example:
The latest data comes in the form of a December to February temperature map on the Met Office’s website.
Reality Check: December 2010 “Almost Certain” To Be Coldest Since Records Began

Again a prediction for a three month period, DJF, is not contradicted by a extremely cold month. In 62/3 the snow started on Boxing Day and Jan/Feb were brutal, there’s plenty of time yet for a real ‘Reality Check’!

That 15 warmest was someone having a laugh. I was surprised at Dominic Lawson picking it up when it was so obviously a piss-take of the Met Office.
