I just get the feeling that these people are trying to justify their previously reached conclusions rather than examining the data.
So the idea is that instead of proving global warming, you prove global blowing :-) and then you argue that blowing and warming sound similar, especially according to your model that links the two. This strategy has the advantage that when the climate begins to cool down, you can also say that global blowing is the same thing as global cooling and the cataclysmic warming can continuously "rotate" into a new kind of catastrophic cooling. :-)
The problems with the particular conclusions by Sherwood and Allen have been discussed by
Roger Pielke Sr,
too. He is preparing a technical manuscript on that issue. The main drawback of their approach is circular reasoning. They want to demonstrate that the models are consistent with reality but what they actually call "reality" is extracted from the models, too.
More precisely, the relationship between the winds and the temperature is derived from the very same models that are shown to disagree with the actual temperature measurements by the balloons and satellites. So the arguments they show only support the compatibility of one particular theoretical prediction with the observations - namely the quantity describing winds as predicted by the very same models.
But a correct model should agree not only with one but with all observed quantities - especially with the temperature if this quantity is the main focus of your models. ;-)
