Rime wonders appear in the Ergun Valley in Inner Mongolia. How was this landscape formed?

The spectacle of rime appears in the Ergun Valley in Inner Mongolia. This landscape is formed by cooling snowfall and heavy fog. The beautiful rime stays on the branches. The cold temperature prevents them from melting, so we can appreciate it. Of course, this kind of beautiful scenery can only be seen through local friends uploading it. It will definitely be more beautiful than watching it live.

Rime, commonly known as "tree hanging", occurs when water vapor in the air directly condenses in low-temperature weather, or supercooled fog droplets freeze directly on the surface of objects, forming white ice crystals. It is white ice crystals that freeze on the branches and leaves when fog and water vapor condense under certain conditions, and gradually dissipate as the sun rises. ?

Recently, the Ergun Valley in Inner Mongolia has experienced cooling, snowfall and heavy fog, followed by a dreamlike rime landscape. Suddenly, a spring breeze comes overnight, thousands of pear trees bloom, the sky and the earth are covered in silver, and the endless jade trees and flowers are quiet and beautiful in the cold winter. The conditions for the formation of rime are harsh and its duration is short. It is a very rare natural wonder. That day ushered in cooling snow and heavy fog. After the heavy fog, a dreamlike rime landscape appeared in the area.

Cold weather in winter. Since rime is formed by the condensation of water when it encounters cold air, the most direct factor in forming rime is at low temperatures. Generally speaking, rime forms easily when the temperature reaches below minus 26 degrees Celsius. There is plenty of water vapor in the air. Generally speaking, if a place is foggy, snowy, with high air humidity and sufficient water vapor, rime will easily form in that place. In a high-humidity environment, accompanied by cold air, rime forms.

The wind speed is small. Sunny days and white clouds are also one of the conditions for the formation of rime. When there are no clouds at night, the surface temperature is relatively low and the temperature drops significantly, which is conducive to the formation of rime. Radiation cooling is intense. Generally speaking, radiation cooling in winter is relatively strong, resulting in a relatively obvious temperature difference between day and night. During the day, the surface of the earth can receive solar radiation, causing the temperature to rise; at night, due to the effect of radiation, the surface of the earth is not only unable to absorb sunlight, but also emits heat outwards. These will speed up the formation of rime.

The beautiful scenery of rime is one of nature’s masterpieces and a luxurious reward in winter. Some people may have seen it frequently, but there are also many people who can only get a glimpse of it through videos and pictures, which is a pity. During your lifetime, you must see a rime and appreciate the most beautiful scenery of the North.
