Amazing what just 5 days can do to ice cover when the bottom falls out of
the thermometer !

Correct me if I'm wrong here, the image on the left is what it was on
the 16th Jan 2006, the image on the right is the 'normal' (average) for
the 21st Jan, NOT todays scene.

You read it correctly, Keith. This chart for yesterday shows the Baltic
still clear of ice:

If the very cold conditions persist the situation is likely to change
quite quickly.

Do large rivers stop flowing when the ice is bad, or do they tunnel
through somehow? It would appear that when ice forms, there is
something in the nature of supercooling observed in the way that
crystals form in large resevoirs.

Obviously I don't mean that there are seriously cold temperatures
involved but that there is a degree of purification taking place in
order to produce tendrils.

If this happens in river mouths it would allow for the tunnelling of
fluids under a little pressure -and of course, ice melts quite easily
under pressure anyway. Anyone know, offhand, how soluble ice is under
pressure?

Yes you are right lads ,sorry I started it ,especially as the
'Weatherlawyer' has reappeared !

I have put a copy of this afternoon's noaa12 pass over Finland on the web
page. There is a lot of cloud over the sea, but it does give some idea of
the ice cover around the west facing coasts.

Looks frozen this morning though.
