Met Office forecasts
Jan 6, 2009 Climate
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.
January:2009:Severe weather warnings have been issued as temperatures in the UK dipped as low as -11C (12.2F) overnight.

Its one thing to lose the confidence of the informed, but the government and MO have managed to lose the confidence amongst the greater un-informed public which puts them on very shaky ground.
“And the Met Office still stands by its long-range forecast of a milder end to the winter. “

They can’t lose if at some arbitrary period at the end of winter we have couple of weeks warm weather :)
I seem to remember them saying something similar after the early December cold snap. They are using the same open ended predictive technique of the stage psychic, I am often amazed that a little more critical scrutiny isn’t applied to them by the media. I guess the MO feel safe in that occupy the unquestionable ‘moral’ high ground.

Piers Corbyn is a bit Barnum & Bailey for me, but his opinions make interesting reading, and I'd back him over the Met Office any day.
IIRC, the MO insisted (rather tetchily) some years ago that long-range forecasting wasn't possible, so they rather burned their boats there!
Even that is an exaggeration for wind at this precise moment. Just when our needs are greatest, because of the cold weather, our output of wind-power must be less than "very little", because of the same high-pressure system that has caused the cold weather.
Wind-fans argue that if we had better networks, the wind will always be blowing somewhere. But it would need to be a big network, with massive redundancy, in conditions like this. The UK is not remotely big enough. Western Europe wouldn't be big enough. In these conditions, we would need a network that stretched from Scotland to Greece and from Spain to Estonia, to achieve reasonable smoothing through geographical diversity. It would need to be a completely new, DC network because of the losses on AC over that distance. It would need massive duplication of wind capacity over that network. The cost would be immense. And the geopolitical insecurities huge. Hardly an answer to our energy-security problems.
The reality is that wind-power cannot serve much more than the 20% of our electricity demand (7% of our energy demands) that always used to be assumed (before the Renewable Energy Directive made it necessary to lie), and needs standby thermal generation capacity equal to almost the whole of the wind capacity. Like a pan-European HVDC network, keeping those power-stations available but idle won't be cheap.
Sorry if this is a little off topic but it 'met office joke' related 8-). If recruitment poor, it`s no wonder the forecasts can be rubbish although that is based on hokery pokery anyway. The met office act as a trading fund so have the benefits of the civil service plus extra money sloshing around due to selling their services. Other more crucial Ciivil Services don`t have the same money to access so their poor employees have a harder time of it.
How nice to hear from you again! Any sign of a return to blogging?
The farm has not produced more than about 90% installed capacity, and only produced over 80% for about 10% of the time. It only gets to 60% about 40% of the time and is below 20% for about 15% of the time.
The capital outlay is twice that of Geothermal Station, which can then run at 100% of installed capacity. There were other conclusions but I think you can all guess what they were.
Now I am a New Zealander so I know how windy it is there, not too dissimilar overall to the UK, so if they can not make it viable, there is no hope here where the population is greater, and the need greater still.

PeterMG, for availability figures for renewable-electricity projects in the UK, see the excellent reports prepared for the Renewable Energy Foundation at http://www.ref.org.uk/Pages/4/uk_renewable_energy_data.html.
One of my favourites is that usually-stationary sculpture beside the M25 near Kings Langley. It is at the head office of RES, one of the largest developers of wind farms in the world. And it achieves a magnificent 8% load factor (see p.199 of REF's wind report).
