Following on from the blog post yesterday about the Met Office’s Julia Slingo claiming the recent ‘freak weather’ (aka a cold winter) could have been predicted if only the Met Office had more supercomputing power…
AM emailed respected meterology experts Joe Bastardi and Piers Corbyn to ask them what supercomputing technology they employ that helps them to generate forecasts that are consistently more accurate than those of the Met Office.
Both gentlemen, who enjoy an excellent track record for their forecasting accuracy, have very kindly replied and their answers are published in full below:
Joe Bastardi said:
I look at the models, and I do use them as input to the forecast with many other factors. However they are not Gods, and to make the excuse we need a bigger computer when in reality all they do is arrive at a solution … right or wrong … faster, and have nothing factored in about past weather events, or natural cycles, or some of the other things Piers and I use, seems to me to be blaming the model and then saying you need more of what failed in the first place.
If the Physics is not right, then forget it. Modeling for instance, relying on greenhouse gasses to warm the atmosphere will come out at a warmer solution. The UKMET model now has suddenly flipped to a cool solution across much of the world for the coming months, but well after it was obvious to us that major cooling was going to occur ( last March I said 2011 would try to return to near normal, similar to the La Nina of the late 90s and the recent one… That is because I knew before the computer a major La Nina was coming on and said so in February.. and based the high total number of hurricanes for the season on the La Nina and the very warm tropical atlantic at the time ..which has cooled since then, btw).
As someone who has no access to public funds, or grants, well I don’t have the computer they do.
Which is interesting since I think we can agree since I joined this little forecasting battle the past 3 years, I have hit the cold over in Europe. Part of the reason is the model and computer has a warm bias since the PDO ( Pacific Decadol Oscillation flipped to cool). Now I wonder why that would be?
And what will happen when the Atlantic turns cold? Throw in solar cycles, and increased arctic or tropical volcanic activity… no computer is going to handle that.
Computer models are tools to get an answer, but not the answer. There is the difference. These folks have not had the kind of forecasting experience that Piers and I have, so they put all this faith in models. We use models, but only as the icing on the cake so to speak. While both of us may have our favorite major climate driver, The ability to see all the players on the field is enhanced when one does not rely on the computer. A good forecaster has to have a visual idea of what a pattern should look like BEFORE HE BRINGS IN THE COMPUTER MODELS, and then have the models confirm or question his conclusion.. much like team mates challenge each other in competition.
To simply use the model as the number one input to ones forecast.. well then what is the need for the forecaster? Maybe that is what this is all about, getting rid of any human touch to the weather, and convincing the public its so. Either that, or saying. I give up, I cant do it, so I will let the model do it. Well I not cut from the cloth that backs away at challenges in things I was made to do, one of them forecast the weather, so I do not become a puppet of models, but instead will accept the model as a team-mate.. another source of input. But that is all it is.
A forecast for instance, for winter starts way in advance, looking at many years of past weather to understand similarities to where we are now UNDERSTANDING THE MAJOR PHYSICAL NATURAL DRIVERS that are affecting the pattern and also understanding where we are in the climate cycle and not assuming that the earth is headed in one direction.
Such open mindedness and the crucible of capitalism and competition, where if not right enough, Piers and I will get fired, makes a bigger difference than just saying I need more money for a bigger computer so I can rely on it.
Funny but true, a video I did back in March showed 11 year cycle forecasts for the summer indicating a warm US summer, while NOAAs computer had it cool for summer Guess what one was right. The 11 year cycle forecast.
Last Spring, the computer had a very warm winter for Alaska this winter, which I hammered. Well guess what is going on.
The UKMET model had a warm winter this winter. Well.
It’s not the computer, it’s the limits of the computer in trying to adjust to what only men can understand and use. I dont think you need more money to arrive at the wrong answer faster. Should put it into fighting hunger, or giving men a chance to be free enough to dream and pursue that dream… much better causes in my opinion.

In WeatherAction my Solar Lunar Action Technique (SLAT) does involve a number of equations and theoretical concepts (Weather action indicators) and calculations which are all performed on a pretty low level PC.The key thing to understand is that all weather circulation patterns have near enough happened before; the key is to find out when and how this time around they will be not quite the same as before.
I explained at some length HOW & WHY my technique(s) work at our WeatherAction Climate Fools Day conference in October 2009 held at Imperial College London. The Warmists were explicitly invited and given a slot to speak but none came.
A video of one of my invites, made direct to John Ackers of Friends of The Earth live on Sky news in October 2009, is linked below. Looking at it now I find it even more hilarious than at the time (when we had ’50 days left to save the Planet’) and suggest readers have a look and a laugh (no mention of ‘cold is warm’ here!!)

The GWers claim that we haven’t explained what we do. That is untrue. The truth is they don’t want to know and don’t want anyone else to know {Recall Phil Jones CRU E-mails described me as The MAIN enemy on the Europe side of the Atlantic and that he and his mates would do everything in their power to prevent the likes of me ever getting anything into print}. I thank blogs such as this which have enabled me and Bastardi and loads of others to break partly through the Greenwash cult.
I say our technique(s) plural because they are evolving and now on Solar Lunar Action Technique – SLAT5b, which supersedes our SWT (Solar Weather Technique). What I do is very different from Bastardi who is clearly also skilled especially for USA. Nevertheless his approach is more Earth-based, not so far ahead and less skilled and much less detailed [Of course we are not always right but I would just like to mention Xmas Day and the nights before and after in the UK were EXTREMELY COLD as we predicted from during November when I placed some successful bets on the matter of snow, contrary to his ‘It will turn mild’ prognoses].
A few links here explain key ideas of what I do –

On supercomputers and the The Met Office I would say that no amount of spending on their approach will ever produce better forecasts in any forecasting more than 3 days ahead. Standard Meteorology has reached the end of its potential. It can go no further. What we do is infinitely more skilled (since they have zero skill) in any long range forecasting. Let’s be clear no amount of investment in wax technology will ever produce a light bulb. For a small fraction of the extra money they want to waste on supercomputers we could reliably forecast extreme events and general weather development details across the WORLD many months ahead.

Please note: If you’re a blogger or journalist and wish to quote from either response, please provide a link back to this post so your readers can see the comments in their full context and avoid any misunderstanding – it’s only proper.
There is clearly an overwhelming case here for challenging the Met Office robustly about its assertion that it requires additional huge sums of money to purchase more supercomputing technology. The question is, will those who control our tax pounds undertake that challenge and stop our money being spent wastefully? Bastardi and Corbyn’s replies demonstrate that the fundamental difference between the Met Office and those meterologists who forecast with much greater accuracy is a matter of technique and approach rather than technology and processing power. The politicians need to understand this.
I’m extremely grateful to Joe and Piers for taking the time late on New Year’s Day to consider the question posed on this blog and write such detailed replies so quickly. Thank you gentlemen.
