Ice meteors, climate, sceptics

Fine - put forward another explanation for the correlation between
lifting footpath bans and the late 2001 appearance of circles in
British crops.

then go to foot and mouth.

2001 has very similar figures for April as 2000 and 2002.

Grant suggested that ice meteors be in the crop circle category of fakes.

But are they fakes, for if they aren't all then that argument may have to
be ruled out.

No-one has commented on polar stratospheric cloud. Grant pointed out how
thin the atmosphere is there. They occur in the winter. Maybe conditions
are sufficient to make clouds of water from cometary fragments. Can any
large fragments get through?

We touched on vortices. Vortex theory was advanced by Kelvin and Thomson,
but superceded by the particle theory, though particles were found to have
spin. Maybe spin can have a laser effect. Sorry about the dreaming. The
simple wind vortices would seem to produce too irregular a form to be
recognised as a crop circle.

Is there any theory of how smoke rings can bounce off one another, and can
that happen with any atmospheric clouds?

Grant said that if vortices were present which could form ice meteors then
there would be clouds, too. But is it possible to have in the upper
atmosphere a wind sort of like the Antarctic katabatic, 350 km/hr with a
clear sky?

What is the velocity of wind in the clear air turbulence which affects
aircraft?
