That's absolutely correct, Bob. :-) Then add abrasion by wind inside the clouds, and temperature gradients in the air column through which the crystals travel before they reach the ground, and you end up with a rather complex picture. I think the big variation between years over here is an indication that the Oslo and Michigan sky conditions are quite different, but I couldn't say exactly how.
