What is frozen fog called?

It’s called rime ice and has been the product of foggy and below freezing start to the New Year. The feathery crystals have provided for fantastic images across Northeast Wisconsin: Rime ice in Luxemburg.

What’s the difference between fog and freezing fog?

When these water droplets come in contact with any surface below freezing, they immediately freeze on that surface.

What does rime look like?

Rime ice forms when supercooled water liquid droplets freeze onto surfaces. Hard rime is somewhat less milky, especially if it is not heavy. Clear ice is transparent and homogeneous and resembles ice-cube ice in appearance. Its amorphous, dense structure helps it cling tenaciously to any surface on which it forms.

Is mist the same as fog?
