A visual feast in winter! Please take a good look at the national rime map and see the best viewing period in various places.

China Weather Network News If you want to meet the fairy tale world of "Frozen" in winter, besides expecting snow, enjoying the rime has become a choice for many people. Rime is neither ice nor snow, nor flowers nor fog. It is a visual feast in winter. At present, many places in China have entered the best viewing period of rime. What are some good places to see rime? What are the special conditions for the formation of rime? China Weather Network has specially launched a national rime viewing map to show you the most beautiful rime and feel the temperature of ice and snow.

Many places in China have entered the best viewing period of rime, which can be seen in both north and south.

Rime can be seen in the north and south of China. As long as there are cooling water droplets in the fog, it can be formed at a certain temperature. It is common in the adjacent waters with high humidity in the north and in the mountainous areas in the south.

In the north, northeast, Inner Mongolia, Xinjiang and other areas with long winters, it takes a long time to enjoy the rime. There is a 50-kilometer-long rime belt in Aershan, Xing 'an League, Inner Mongolia, which is known as the "baili rime corridor in Daxinganling". The seven-month ice and snow period provides natural protection for the rime landscape. There are many places to enjoy rime in Jilin, and rime island and Songhua River are both famous rime viewing places. The rime in Majie Scenic Area of Changbai Mountain is more mysterious than the general rime viewing place because of the heavy fog.

Tianmen Mountain in Hunan, Hengshan Mountain in Anhui, Huangshan Mountain and Emei Mountain in Sichuan are all excellent places to enjoy rime, among which Emei Mountain has the longest rime viewing period, with an average of more than 140 days per year.

The shape of rime can be divided into granular and crystalline. Wang, a meteorologist from China Weather Network, said that granular rime was formed when supercooled droplets were blown by the wind over slender objects, and the wind played a key role in its formation. Crystalline rime is mainly the condensation process of water vapor at low temperature, which needs to be below-15.

Are all the tree hangings rime? Rime and rain are silly and indistinguishable.

People often confuse rime with rime. According to Wang, there are differences between them. Rime is an ornamental landscape formed under natural conditions of low temperature and high water vapor, and it is a natural "air humidifier" that provides sufficient water for overwintering crops. However, glaze is the product of freezing rain, and hanging ice often bends wires and trees, causing disasters such as power failure and tree lodging, which is disastrous weather.

Rime is the product of freezing rain, and it is the landscape of ice crystals and tree hanging formed after freezing rain. The formation of freezing rain also needs specific meteorological conditions. The atmospheric temperature of precipitation is below 4000 meters, and the phase states are ice crystals and snowflakes. However, when it passes through the atmosphere of 2,000 to 4,000 meters, it encounters a warm layer with a temperature higher than 0, and the precipitation becomes a water droplet phase, and then it enters the cold layer again before landing, but it is too late to freeze and becomes supercooled water droplets. When landing, it comes into contact with cold objects, and the surrounding environment is lower than 0, thus forming ice crystal tree suspension.

In China, Guizhou has the most freezing rain and freezing, followed by Hunan, Hubei and Henan. In the north, it is also common in Shandong, Hebei, Liaodong Peninsula, Shaanxi and Gansu, among which there are more mountains than plains and the most mountains.

Once the glaze appears, measures must be taken in time to clean up the tree hanging covering trees and wires in time. People should go out as much as possible to avoid the tree hanging from a height and hurting people.

Please put away the rime in winter. Morning is the best time to shoot.

Because the viewing environment of Rime is very cold, it is suggested that friends who watch Rime wear down jackets, hats, gloves and scarves. At the same time, bring warm artifacts such as warm babies and thermos cups; In addition, snow has a high reflectivity to sunlight, so it is best to wear sunglasses to enjoy the scenery.

In addition to enjoying the scenery, it is also skillful to shoot rime. First of all, rime usually appears about 2 hours after sunrise, and morning is an excellent time to shoot rime; Secondly, we should choose the correct light level. Generally speaking, we don't shoot rime in a smooth environment, and we often shoot rime in gray. In order to get rich and textured rime pictures, we should shoot rime in side light, side backlight or backlight. In addition, because the temperature of the rime viewing environment is generally below freezing point, the camera should be sealed with a sealed bag before entering the room after shooting, and the camera should be kept warm to avoid damage to the camera due to the large temperature difference between indoor and outdoor parts.
