The rime and snow scenes in Zhangjiajie seem to have entered a fairyland on earth. How was this natural landscape formed?

The rime and snow scenes in Zhangjiajie seem to have entered a fairyland on earth. This natural landscape is caused by the countless uncondensed water vapor below zero degrees Celsius in the fog that accumulates and freezes on branches and other objects with the wind. formed. The conditions for the formation of rime are cold and long winter, sufficient water vapor in the air, sunny weather, partly cloudy and still, or low wind speed. Clouds in the air weaken the outward long-wave radiation, causing the ground temperature to drop slowly, and the temperature difference between day and night is relatively small, so that water vapor in the air near the ground does not condense. Generally in winter, the probability of calm or breezy weather and sunny days at the same time is low. In addition, when there is cooling fog, it is especially conducive to the growth of ice crystals on ground objects. At this time, white rime forms on wires and branches.

1. Clouds in the sky are like a quilt on the earth. When there are clouds at night, the outward long-wave radiation is weakened, causing the ground temperature to slowly drop. The temperature difference between day and night is relatively small, and the water vapor in the air near the ground will not condense. . If the quilt is removed, more heat will be emitted, which will lower the ground temperature and provide necessary conditions for the condensation of water vapor. It is the natural enemy during the formation of strong wind rime. During the formation process, it can always blow away the loose ice crystals, and even the gathered rime will be blown away without a trace. Breeze or calm wind conditions provide a guarantee for water vapor to condense into rime.

2. Rime is a natural air cleaner. When people watch Jilin rime such as Yushu Qionghua, they will feel that the air is particularly fresh and nourishing, because rime has the inherent function of purifying the air. When rime appears, it is usually very cold, so everyone should pay attention to keeping warm and cold when watching or taking photos of the beautiful scenery of rime. Wear thicker clothes, preferably a brighter jacket, so that you can have better photography effects in the white rime scenery.

3. Strong wind will blow away the loose ice crystals and make the rime disappear. Breezy or still wind conditions can provide for the condensation and condensation of water vapor into rime. In addition, when there is cooling fog, it is particularly conducive to the growth of ice crystals on ground objects. The above is the answer to the question of how the rime and snow scenery in Zhangjiajie was formed, as if entering a fairyland on earth.
