Why is there rime in Daming Mountain?

Rime is a kind of white or milky opaque ice layer attached to the windward surface of ground objects (such as branches and wires). It is also formed by condensation of supercooled water droplets. However, these supercooled water droplets did not fall from the sky, but floated in the airflow and were taken away by the wind. This kind of water drop is much smaller than the raindrops that form rain, and is called fog drop. In fact, it is also the cloud droplets that make up the cloud. When they touch the surface, they will freeze quickly. Because there are many gaps between water droplets in the rime, the rime is completely opaque white. The rime is pale and white, attached to trees and objects, just like a silver flower of a tree, delicate and elegant. This is the tree hanging (also known as the snow hanging). The rime spectacle on the Songhua River in Jilin City is very famous in East Asia.

Rime has low density and light weight, and is much less destructive to wires and trees than rime. When the rime on the wire is serious, it will break the wire and cause power failure!

hoar frost

When supercooled water droplets (temperature below zero) collide with objects also below freezing point, rime will be formed. When water droplets are very small and freeze as soon as they touch objects, a rime layer or rime deposit will be formed. The rime layer is composed of small ice particles with pores between them, which leads to a typical white appearance and granular structure. Due to the rapid freezing of each supercooled water droplet, the cohesion between adjacent ice particles is poor and it is easy to fall off from the attachment. Rime is most likely to form at the top of the mountain surrounded by Leng Yun. This is also a common form of icing on airplanes. In cold weather, steam fog near springs, rivers, lakes or ponds can also form rime. Rime is a kind of natural beauty that people generally appreciate, but it sometimes becomes a natural disaster. Severe rime sometimes breaks wires and trees, causing losses.

glaze

When supercooled precipitation hits the surface of an object with a temperature equal to or lower than zero degrees Celsius, a glassy, transparent or dim ice sheet with rough surface is formed, which is called rime. Commonly known as "tree hanging", it is also called ice and tree condensation, and the rain that forms a rain is called freezing rain. In southern China, freezing rain is called "ice", "sky" or "cowhide".
