It is estimated that many people have seen the scene of " dragon sucking water " on the Internet. In the sky covered with dark clouds, a thick water column rises from the water and goes straight to the dark clouds in the sky. It seems that something is going on between the sky and the earth. The transmission of materials and information, because the rolled-up water column is more conspicuous than when a tornado is formed, it is easier to observe, and the visual effect is more shocking. Of course, the scene of "dragon sucking water" needs to be formed on a specific occasion and at a special time. Generally speaking, the probability of it happening is very low. Being able to witness this spectacle with your own eyes can be said to be rare.
However, since the beginning of summer, "dragons sucking water" have appeared in many places in our country. For example, on May 31, in Qinghe Town, Tonghe County, Harbin, Heilongjiang, "dragons sucking water" formed twice on the surface of the Songhua River within a few minutes. The spectacular sight of a dragon sucking water.
html On the afternoon of June 30, another spectacle of "dragon sucking water" appeared on the sea near Jizhao Bay, Wuchuan City, Zhanjiang, Guangdong, forming a funnel-shaped "water dragon" in the sky and the sea. After more than ten minutes, the water dragon continued to form. Moving towards the coast, the water column of "dragon sucking water" disappears.
On the morning of July 2, the "dragon sucking water" phenomenon was staged again in the waters near Qing'ao Bay of Nan'ao Island, Shantou, Guangdong. Many people can't help but wonder why the originally rare "dragon sucking water" has appeared frequently in different areas thousands of kilometers apart in the north and south of my country in the past month or so.
Let us first take a look at what "dragon absorbs water" is. In essence, "dragon absorbs water" is a vortex phenomenon of air, which is a natural phenomenon caused by the rapid rotation of the surrounding air around the center of the dragon scroll. Since the air pressure in the center of the tornado is lower than that of the surrounding area, the surrounding air will quickly fill in. At the same time, when the tornado is formed, the air temperature on the ground is higher, so it will form a situation of rotating and rising at the same time. When the flow rate and intensity reach a certain level, some objects at the bottom of the tornado will be sucked in and thus visible to the naked eye.
Therefore, the reason for the formation of "dragon absorbing water" is exactly the same as that of tornadoes, except that the area where the tornado is formed is on the ground, and the things swept in are dust, branches, stones and other surface objects; while "dragon absorbing water" is If it happens on the water, the thing involved is naturally water. If it happens on the sea, then the thing involved is sea water. This phenomenon is also called " seaspout ".
Sometimes, tornadoes and "dragons absorb water" can transform into each other. As the rolling air flow moves on the plane, sometimes it moves from the land to the wide sea or water surface, at which time it evolves from a tornado to a "dragon sucking water"; sometimes it also moves from the sea or water surface to the land, at this time The inhaled water falls under the action of gravity, forming a regional heavy rain with greater intensity. If the intensity is still very high at this time, it will also re-roll objects on the ground into the vortex.
It can be seen from the main formation process above that the formation of "dragon absorbing water" requires the following necessary conditions. One is that the temperature of the water surface is relatively high, and the transpiration of water vapor shows a violent upward movement; the second is that the upper part It is usually connected to cumulonimbus ; thirdly, the water surface must be wide, with sufficient water vapor and water injection conditions. The fourth is that the shear between the updraft and the downdraft is larger. This is also the reason why "dragon sucks water" mainly occurs in offshore areas with wide views, large lakes or rivers. For example, near the Paracel Islands in the South China Sea of my country, the probability of "dragon sucking water" is very high every summer.
The "dragon water absorption" that occurs in the sea sometimes echoes with typhoons. If you are on the edge of a typhoon, then when the huge airflow of the typhoon flows rapidly, the air in the surrounding area itself has very large kinetic energy. This provides additional air movement driving force for the local occurrence of "dragon water absorption".The several "dragon water sucking" events that have occurred in the coastal waters of Guangdong in recent days are naturally caused by the conditions mentioned above. However, the recent landfall of Typhoon Siam on the coast of my country is also an important inducing factor. This has been Confirmed by meteorological experts.
Compared with typhoons, although "Dragon Water" is much smaller in scale, with a diameter usually no more than one kilometer, and some even only a few dozen meters, the internal wind speed is not smaller than that of typhoons, and can reach 100 kilometers per hour or even Larger, its damage is no less than that of a tornado. Like a previous case, the "dragon sucking water" that occurred in a certain area along the coast of my country moved to land. As a huge amount of seawater fell, many fish, shrimps and other marine animals were sucked in. The gravity dropped one after another, causing a scene dubbed " fish rain ", which also produced great destructive power.
Due to the formation of "dragon water absorption", like a tornado, it mainly relies on the violent convection of air in a local area. The flow of air is difficult to detect in time with the naked eye and monitoring equipment. It can only be detected when something is sucked in. It will be discovered, so it is currently very difficult to accurately predict when and where it will occur, and it will become one of the world's problems that meteorologists will work hard to overcome in the future.
Whether it is a "dragon sucking water" or a tornado, due to its fast moving speed and strong wind, once it enters human production and living areas, its destructive power is still quite amazing. For example, after entering farmland, it will destroy everything it passes. Crops will be uprooted, and serious lodging will occur in surrounding areas. If you enter a densely populated area, it will also cause damage to buildings and infrastructure, and objects dancing in the wind will also pose a threat to the human body.
Therefore, if you see "water dragons" and tornadoes outdoors, do not follow them just for curiosity. It is best to return indoors as soon as possible and close the doors and windows. If you have no conditions, you should also find a safe and concealed area to take shelter. After all, They don't have eyes, and your running speed can't keep up with their movement speed. If you catch up, you might be sucked in.
