wonder! The Yellow River is "boiling": the continuous low temperature in most parts of the country

On December 16, a rare spectacle of "boiling" appeared on the Yellow River in Bayannur, Inner Mongolia. This phenomenon is because the evaporated water vapor on the Yellow River condenses into small drops when it is cold, forming a layer of fog and covering the water surface.

According to professionals, this natural phenomenon is caused by the wide water surface and large depth of the Yellow River. Due to the high specific heat capacity of river water, the temperature is relatively high when compared with the surrounding environment. When cold and warm ice water meet, a large amount of water vapor will be generated, which will condense into fog when the wind is not strong, thus forming the effect of "boiling the Yellow River with water".

Recently, the temperature in most parts of the country continues to be low, and the cold weather will continue in the next five days. The Central Meteorological Observatory issued a yellow low temperature warning: it is expected that the minimum temperature in northern Xinjiang, eastern Northwest China, Inner Mongolia, North China, Northeast China, the Yellow River and Huaihe River will be 5 ℃ lower than that in the same period of history from December 18 to 21. Among them, the minimum temperature in the eastern part of Northwest China, Inner Mongolia, North China, Northeast China, the middle and eastern parts of the Yellow River and Huaihe River and the eastern part of the Yangtze River and Huaihe River will be more than 7 ℃ lower than that in the same period of history. At the same time, the lowest temperature line will be formed from southern Guizhou to northern Jiangnan.

In addition, it is expected that there will be rain and snow in the middle and lower reaches of the Yangtze River and areas to the south from the 18th to the 19th. Small to moderate snow (rain) or sleet may occur in central and southern Anhui, central and southern Jiangsu, Shanghai and northern Zhejiang; Light rain may occur in Jiangnan and South China, and moderate rain may occur in some places; Freezing rain may occur in high altitude areas such as north central Guizhou and western Hunan.

These extreme weather conditions have brought great trouble to people. I hope you can take precautions, pay attention to warmth and make reasonable travel plans.
