It turns out that hoarfrost and rime are different natural phenomena, but after reading the characteristics of both, I still did not understand what their difference is. But if still believe the description, then rime is most often found in nature, not hoarfrost.
Hoar tends to grow more on horizontal surfaces, and rime on vertical ones.
R manifests itself as precipitation, meaning that water vapor crystallizes in the air even before it comes into contact with surfaces and objects.
And so, here lies a leaf...It got colder...but there is fog or water vapor in the air.
And there are two ways to cover this leaf with crystals.
First, water vapor or mist cools in the air at subzero temperatures and settles on various surfaces. And if the vapour in the air freezes, it can settle on wires, grilles, and tree branches. It will be rime.
The second one: a leaf was lying there and cooling down at subzero temperatures, but then microscopic drops of water in the form of mist or vapour came into contact with it and due to the fact that the leaf is already in the "minus", they turn into crystals on it. It's hoar.
But I don't know what processes were going on at night while I was sleeping...
I'm worried about what I saw – ice crystals on the leaves and grass. And now go and figure out under what conditions they ended up on the plants...
It can be either hoar or rime.
Other differences: the hoarfrost is sharp, needle-like and translucent.
The rime is more matte and looks like cotton wool.
If there was fog at night, expect rime! If it was a clear night– then hoarfrost will appear!
And I still haven't decided what I was filming...
