The prevailing wind was still south-westerly!

The earth was covered in water at one time old boy but it wasn't solid.

If Noah had divine help, I imagine a major Low Pressure Area would have
held the Ark in it's centre. It wouldn't suprise me to find that there
is a reason to suppose the Ararat Range has an amphidromic point
somewhere that might have made a good landing stage a few years ago.

Interesting fairly recent thread in sci.military.naval discussed several
Chinese vessels from a few centuries back that were the about the same
size and faily similar in structure too.

Not that I am intending to preach to the unwashed. It's just one of
those things one hones in on when one is interested in geophysics.

High pressure would probably have covered the ice sheets for most of the
time. There was no or very little in the way of a thermohaline circulation
and therefore less likelihood of a Westerly flow. Take all of the great
winters of the past, each one has had a major high pressure system involved
at some stage.

Unlikely, what?

The ability for the anticyclones to maintain cold air through a summer
is a little far fetched isn't it?

As for the lows, they tend to reach five or so degrees Centigrade higher
than the norm in winter, do they not?

Still each one to his own gods I suppose.

(Bloody fools.)

Not according to H H Lamb. The main Atlantic Low was much further
south than today (45-50N) and the prevailing wind over the UK was
roughly SE'ly.

And how up to date was that research. It's a known fact that the last
severe glaciation ( coldest part of the last ice age ) was an average of 10
degrees Celsius colder than present. There was ice hundreds maybe thousands
of feet thick covering a large part of the Northern hemisphere, I can tell
you now, the circulation of that time was very different.

There must be ten or more different ideas relating to ice age climate, mine
is just one, H H Lamb is just one of many.

I think his ideas possibly carry a little more weight than
yours.

Maybe, but there is tons of material available on the internet, all with
differing ideas, take you pick!!
