A friend of mine (not a weather nut) takes it as axiomatic that a

warmer world would be a windier one (including the UK) whereas I am

not convinced that this is necessarily so. In fact, I can think of

good reasons why the opposite might be true. The temperature gradient

between pole and equator is less due to the disproportionate warming

in high latitudes and this will reduce the vigour of the circulation

and probably increase blocking. That, of course is hardly the last

word on the subject so does anyone here have any special knowledge of

what climate models predict or can point me to some literature?



Tudor Hughes, Warlingham, Surrey.



There was a RMetS meeting last Wednesday where the evidence from earlier

warm periods in the Earth's history were compared with the results of model

simulations. The models seem to be unable to replicate the polar

amplification of temperature found in the temperature proxies. So I would

not trust the models in getting the changes in the wind correct. The

abstracts

of the talks are available he

In the geological past, the Arctic region was sub tropical with crocodiles

swimming around Elsmere Island. So the temperature contast between the poles

and the topics was much less. Howver there would have been more likelyhood

of hurricanes.



Cheers, Alastair.

Well Alastair those Crocodiles are notoriously wasteful with carbon fuels.
