A clairslide is a 'clear, cold air landslide'. I used to use 'air glacier' or 'cold blob'. It is jelly sliding off a plate. The cold air is so dense, it has the properties of cold jelly, ice, or tons of dirt.
I save 'clairslide' for absolutely clear air, coming down fast, with a rounded (lobate) front. Don't worry that nobody else in the world uses these terms. I never worry, and my 9 loyal readers don't, as well.
The core is at 50 below. The Great Lakes Heat Shield is down, and the clairslide will run over it. The warm Arctic ocean has turned over, and can now hold -60. The cold comes to freeze the bezeebees off the Eastern Intellectuals. They're rich enough to afford natgas, while trying to double the price of heat-carbon for everybody else. Their sole purpose is to reduce the 'Standard of Living' to frozen death for millions.
I am now amazed at the low price for natgas. They must believe the phillies. This year or next, they will run out of stored gas, and be like Europe. All the wells are blowing up with freezing, and this is much worse than phillie demands to 'shut it all off'.
The Toronto forecast is for -18, much colder than the long-range forecast, and the next one will be -30. That makes it expensive for all the housing money laundry people to heat. Now, all carbon will double in price, and interest rates will go through the roof (literally, with the expensive heat energy).
ps. the UK is now in a repeating pattern of a tropical plume pushed away by a clairslide. Frozen Hell, rinse, repeat.
