Winnipeg was in a classic winter wonderland situation in late December and early January, with lots of rime frost on everything, especially trees.
Rime frost forms when it’s well below freezing and there is fog. The water vapour turns into liquid water droplets that then freeze onto branches and other things.
Hoarfrost is different, it forms through sublimation (water vapour crystallizes directly to solid form, without turning to liquid first) on clear nights when the dew point is at the freezing point.
If you look at closeup photos they look different. Hoarfrost usually disappears later in the day, while rime frost lasts much longer.
So, here are some photos of rime frosty trees in Winnipeg.
