Forecast of drought in Britain brings record April showers. Time to change climate models?

It is hard to make predictions – especially about the future (Yogi Berra, Niels Bohr, et al.)

The Met Office has caused a storm of controversy after it was revealed their £30million supercomputer designed to predict climate change is one of Britain’s worst polluters.
The massive machine – the UK’s most powerful computer with a whopping 15 million megabytes of memory – was installed in the Met Office’s headquarters in Exeter, Devon.
With a total peak performance approaching 1 PetaFlop — equivalent to over 100,000 PCs and over 30 times more powerful than what was in place before. It is capable of 1,000 billion calculations every second to feed data to 400 scientists and uses 1.2 megawatts of energy to run – enough to power more than 1,000 homes.

So what glorious new and accurate information are they producing now?

Met Office 3-month Outlook
Period: April – June 2012 Issue date: 23.03.12

SUMMARY – PRECIPITATION:
The forecast for average UK rainfall slightly favours drier than average conditions for April-May-June as a whole, and also slightly favours April being the driest of the 3 months. With this forecast, the water resources situation in southern, eastern and central England is likely to deteriorate further during the April-May-June period. The probability that UK precipitation for April-May-June will fall into the driest of our five categories is 20-25% whilst the probability that it will fall into the wettest of our five categories is 10-15% (the 197-2000 climatological probability for each of these categories is 20%).

CONTEXT:
As a legacy of dry weather over many months water resources in much
of southern, eastern and central England remain at very low levels.
Winter rainfall in these areas has typically been about 70% of average,
whilst observations and current forecasts suggest that the final totals for
March will be below average here too. The Environment Agency advises
that, given the current state of soils and groundwater levels in these
areas, drought impacts in the coming months are virtually inevitable.

That was the prediction.

Ho well did they do?

Here is the result for April 2012:

2012 had wettest April for 100 years, Met Office says.

It has been the wettest April in the UK for over 100 years, with some areas seeing three times their usual average, figures from the Met Office show.

 

I am really impressed by their newfound forecasting ability.
So impressed I have written new lyrics to Merle Travis song: Sixteen tons (Popularized by Tennessee Ernie Ford)

Some people say people are made outta mud
Alarmists and warmists, they’re chewing their cud,
Chewing their cud and follow Al Gore
A mind that’s a-weak can you ask for much more?

More than one megawatt, and what did they get?
Another prognosis and deeper in debt
Saint Peter don’t you call ’em ’cause you must let ‘em be
They sold their souls to the IPCC.

They came in one mornin’ when the sun didn’t shine
They picked up their papers and continued the grind
They had sixteen conditions, mostly falsified bull
And the straw boss said “Well, a-bless my soul”.

More than one megawatt, and what did they get?
Another prognosis and deeper in debt
Saint Peter don’t you call ’em ’cause you must let ‘em be
They sold their souls to the IPCC.

They came in one mornin’, it was drizzelin’ rain
their prognoses had failed them again and again
The boss harshly told them, You will do many more
Do as I tell you, and agree with Al Gore.

More than one megawatt, and what did they get?
Another prognosis and deeper in debt
Saint Peter don’t you call ’em ’cause you must let ‘em be
They sold their souls to the IPCC.

The threatenin’ drought, it just didn’t last.
and hidin’ the warming that occurred in the past
Their ol’ man Mann and his hockey stick.
Conditions like that nothing ever will click.

More than one megawatt, and what did they get?
Another prognosis and deeper in debt
Saint Peter don’t you call ’em ’cause you must let ‘em be
They sold their souls to the IPCC.
