What is the meaning of dragon water absorption (what is dragon water absorption, how it happened and how it formed)

What is "dragon water absorption"?

"Dragon sucks water" is a tornado that appears on the water. Its upper end is connected with thunderstorm clouds and its lower end is connected with the water surface. Water swirls from the surface of the water to the sky. A phenomenon like this is not mysterious in itself, although its visual impact is extremely strong. It conforms to the formation principle of tornadoes on land. What happens on the water is "dragon absorbs water", and what happens on the mainland is a tornado.

What weather conditions will it happen?

"Dragon water absorption" usually occurs when the atmospheric environment is extremely unstable, and it is often accompanied by thunderstorms, strong winds and hail weather. The wind and rain roar and dark clouds overwhelm the city, which easily makes people feel frightened. In fact, its destructive power is related to the strength of thunderstorm system. Generally speaking, the maximum wind force of land tornadoes can exceed 12, with great energy and strong destructive power. The waterspout carries a lot of liquid water, which is easy to consume energy in the process of moving, and its destructive power is relatively small. Not only in Hainan, but also in other parts of China, the phenomenon of "dragon absorbing water" occurs from time to time, mostly from June to September.

Yangtse evening post

Yesterday evening, there was a rare scene in the middle of gaoyou lake Lake in the west of Gaoyou City, which had not been seen for decades. Because the tornado formed a black water column (commonly known as "dragon absorbs water"), the water level of the lake suddenly dropped by several centimeters! "Dragon water absorption" lasted for about 10 minutes and then disappeared. Suddenly it began to rain cats and dogs, and the world was in chaos. Fortunately, there were not many ships operating in the lake at that time, and they were all active in the area near the shore. When the reporter published last night, the local official did not receive the accident report.

Two dragons appeared on the water.

At about 5: 45 yesterday evening, many Gaoyou citizens saw a scene that was hard to see in their lives. The area where "Dragon Suction" occurred is about one or two kilometers north of gaoyou lake Royal Pier. Due to the drastic climate change and stormy weather before and after "Dragon Suction", the citizens who were "fortunate" to witness this "spectacle" were deeply impressed by the "spectacular sight" and felt different degrees of fear.

Mr. Huang, who works in the Propaganda Department of Gaoyou Municipal Committee, is one of the few people who witnessed the spectacle of "dragon sucking water" at close range. At 4 o'clock yesterday afternoon, Mr. Huang and his party of six people sat on a small wooden boat and filmed scenery on the lake. There are two children among these six people. It's a sunny day and the lake is calm. But at 5: 30, a strong wind suddenly blew, and then the sky was overcast. A few minutes later, it began to rain. At this time, two water belts formed by strong winds appeared in the northwest corner of the lake. "No, there may be a tornado!" Lao Huang suddenly had a premonition, because in early July, a tornado had just blown nearby. "Hurry to the shore!" Lao Huang almost shouted "command" to the boatman.

Just a minute later, the two wind belts merged into one and floated to the ship two or three kilometers away from Mr. Huang. "At that time, the scene was very tense, and the two children cried on the spot. Fortunately, I was not far from the shore and soon landed. " Lao Huang told reporters that at 5: 40, he saw a shocking scene for the first time in his life, which he will never forget: two huge water columns, one white and one black, fell from the sky, and the water and the sky were connected, just like two unruly dragons, swinging from side to side on the lake!

Quickly synthesize a kilometer-long "black dragon"

After about a minute or two, the two "dragons" merged into a more "huge" black dragon, hovering slowly on the lake. The huge water column is S-shaped, and the part near the water surface is explosive, just like a huge "mushroom cloud". The water column is narrow in the middle and wide in the upper part, like a funnel. According to Mr. Huang's estimation, the length of "Black Dragon" is between1500m and1800m. After hovering for nearly 10 minutes, the "black dragon" disappeared, followed by heavy rainfall, the sky became gloomy and the world was in chaos. "At this time, we saw another' spectacle': a red sun not far away, colorful clouds all over the sky, and' dragon sucking water' existed at the same time. After about 20 minutes, the rain became smaller and the sky became brighter. "

During the tornado, fortunately, there were not many boats on Gaoyou Lake at that time, and most of them were moving on the shore. But to the horror of witnesses, there was a big ship not far from the water column. Fortunately, this ship is relatively strong. After discovering the danger, it ran at full speed and soon landed. According to what he learned from the boat people nearby, there was no capsizing accident.

I haven't seen it for at least 40 years.

"When I was seven or eight years old, I saw' Dragon Suction' on the lake for at least 40 years." Lao Zhao, a fisherman in his fifties, was on the shore at that time. He told reporters that in the past, he had heard from his elders that "dragons suck water" and that the dragon king was "angry", but he didn't agree with what he saw as a child. Zhao Laohan said that when the "black dragon" rose, he noticed that the water level of the lake had dropped by at least five or six centimeters and was swept away. After the heavy rain, the water swept into the sky fell again. After the heavy rain abated, the water level of the lake basically returned to its original appearance.

The hose is black because it rolls up deposits.

Director Chen of Gaoyou Meteorological Bureau said in an interview that it is certain that there is indeed a tornado blowing on Gaoyou Lake, and the "black dragon" mentioned by ordinary people is commonly known as "dragon sucking water". It is black because the tornado stirred up some sediments at the bottom of the lake. Director Chen said that "dragon water absorption" generally occurs in a wide water surface, and its cause is a tornado. Meteorologically, tornadoes that happen on land are called "land tornadoes" and those that happen on water are called "waterspouts". The "Dragon Suction" that happened on Gaoyou Lake yesterday must be more than a kilometer long. This city has not seen such a "spectacle" for decades. According to its analysis, the occurrence of tornadoes is related to strong convective weather. In early autumn, it is cool in the morning and evening, hot during the day, and the temperature difference is large, which is easy to form strong convective weather in some places. At the same time, it is not surprising that there are clouds all over the sky, because the clouds that lead to rainfall have shifted, and there has been a weather phenomenon in which one area is sunny and another area is stormy.
