What wonders have you seen on the sea in Qingdao in extremely cold weather?

65438+1On October 7th, the lowest temperature in Qingdao, Shandong Province reached-15.9℃. Rare marine wonders appear in the waters near Qingdao. Experts say that this phenomenon only occurs in extremely cold weather. It is understood that this phenomenon is caused by strong winds and cool weather. It is this phenomenon that gives Qingdao a rare coastal defense. The so-called haihao phenomenon refers to the fairyland-like landscape on the sea.

There is also a cliff cooling in Qingdao, the whole city is frozen overnight, and even the sea ice and seawater have a rare spectacle. Haihao means that when the temperature of seawater is higher than that of air, seawater evaporates into water vapor, and when it meets cold air, water vapor condenses into ice crystals. Looking around, you can see a rare sight under the viaduct. On one side is a gurgling river with a mist on it. One side is a frozen river, like a mirror. I saw a huge water outlet spewing out, and the sound of water could be heard several meters away. This exit is big and urgent, just like a huge fountain, emitting white air with amazing momentum. Because the water temperature is higher than that of the river outside, and the flow rate is fast and large, the rivers around the water replenishment point do not freeze in such cold weather, forming a unique spectacle of ice and fire.

Experts' explanation for this phenomenon is that this phenomenon will only appear on the sea surface in extremely cold weather. At the beginning of this year, Qingdao did have extremely low temperature weather. So, what is the reason for the ultra-low temperature in Qingdao? It is understood that the reason for the ultra-low temperature in Qingdao may be related to La Nina phenomenon. Experts said that the last time this happened was five years ago. At this time, La Nina phenomenon also appeared. So, what is La Nina phenomenon? La Nina phenomenon refers to the abnormal cooling of seawater in the central and eastern Pacific Ocean. In other words, the southeast trade winds blow the seawater heated by the sun to the western Pacific Ocean, making the sea level in the west nearly 60 cm higher than that in the east. At the same time, the sea water temperature in the west rises, the air pressure drops, the wet air accumulates, forming typhoons and tropical storms, and the bottom water in the east appears, which leads to the cooling of the sea water in the East Pacific. When La Nina occurs, Leng Xia fever is prone to occur in winter in China, and the number of tropical cyclones landing in China is more than normal, resulting in drought in the south and flooding in the north.

This year's La Nina phenomenon is probably the reason for the extreme low temperature in Qingdao. At the same time, it is precisely because of this that Qingdao has appeared a phenomenon similar to a fairyland. Five years later, the phenomenon of "Hai Hao" reappeared. Netizens also commented on this. Some people say they saw it in the river when they were children. Some people say that this is a good opportunity to enter Penglai wonderland for a hundred years. In a word, the phenomenon of Haihao still looks spectacular. I wonder when it will appear next time.
