Guangdong women climb mountains with icicles on their hair and eyebrows. What are the factors that cause this phenomenon?

19 February 19 early morning 10, the temperature in Jinshan, Lianshan, Guangdong Province was as low as MINUS 5 degrees, and many tourists' clothes, hats and hair were blown into ice by this low temperature weather. There is also a female tourist with long hair. After playing for 20 minutes, her hair was covered with ice. So what is the reason for this phenomenon?

First of all, this phenomenon must be related to the low temperature weather in Guangdong. Since the strong cold air entered Guangdong on February 18, Guangdong has maintained low temperature and rainy weather, and sleet and freezing rain have also appeared in high-altitude mountainous areas such as Qingyuan, Zhaoqing and Shaoguan, and Guangdong has suddenly widened. Frozen? . Originally, the temperature in Guangdong was low these two days, but the temperature dropped by 0.6 degrees Celsius every time the altitude rose 100 meters, so the top of the mountain was colder than the bottom. This is why the female tourist's hair freezes so quickly.

Second: The reason why this tourist is in this situation is that she didn't wear a hat and didn't take good protection. If she had taken precautions, put on a cotton protective cap and kept warm, her hair would not have frozen into icicles. Of course, I still want to remind everyone that it is best not to go out climbing in extremely cold weather, rain and snow, because that kind of behavior is unsafe.

Finally, the main reason for this phenomenon is the cold weather in China. So the reason why it is so cold this year is:

1. There was an extreme cold wave in January and February. The direct cause of this extremely cold weather is that the polar nest goes south. The reason why Polar Nest goes south is that the extremely strong Ural warm ridge directly rushes into the Arctic Ocean (this is really rare). Polar Nest has nowhere to go in Northeast Asia but goes south, and the weather is cold.

2. Global warming. Under the background of global warming, the frequency and intensity of extreme weather such as high temperature heat wave, drought, flood, typhoon and cold wave will increase. Because global warming has changed the meridional scale characteristics of atmospheric circulation, and affected the local climate through air-sea and ground-air interactions.

3. Arctic warming. Since 20 18 years, scientists in China have revealed that the Arctic is warming rapidly, which was not affected that year. However, with the increasing intensity of warming in the Arctic, it is also an important cause of extremely cold weather.

I hope my answer can bring some help to everyone.
