This is quite dramatic. The air glacier is a clear zone of very cold, dry air. It behaves exactly as a descending continental ice sheet, except a million times faster. The tropical plumes, our only source of heat in the winter, can counter them.
This one is a bit mucky, and I'm cheating by looking at the long-range weather forecast, which is very cold. All the warm, moist air is being shoved away by the density of cold air.
Europe is a battlefield. If we are lucky, everyone at cop26 will get stuck in the snow, or all their carbon-spewing flights will be cancelled. :) Great headline "Carbon Warming Party Frozen Out".
Cold is weather, and I'm allowed to project a little. Read about how the Little Ice Age came in to Holland, and started ice skating. I'm still convinced it ended the Dutch Empire of Rembrandt. maybe
ps. In time for the big 'Frozen' party, the poll is now 99.9%, just like an election in Bela-russia
