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.

I wonder where the dominant pressure systems were located - presumably
somewhat further south than nowadays?

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.
