[Source: Chao News] On the morning of September 8, a rare "dragon sucking water" phenomenon appeared in the waters of Damen Island in Dongtou, Wenzhou. A large number of netizens in Dongtou, Yueqing, Yuhuan, Taizhou and other places took pictures of the scene. Reporters learned f

Thunderstorms and strong winds in the surrounding area can easily trigger "dragons sucking water"

"It's amazing! It's like the door of time and space has opened." That morning, many netizens took photos of "dragons sucking water" in the waters of Dongtou. A video online showed that a few kilometers away from the sea, a huge water column rose from the ground and shot straight into the sky. It looked like a giant dragon reaching into the sea from the clouds to absorb sea water.

According to netizens, the "dragon sucking water" phenomenon appeared in the waters around Dongtou Gate Island and lasted only a few minutes. In addition, netizens from Yuhuan, Yueqing and other places in Taizhou also observed this scene. Based on the observations of netizens, the dragon sucked water this time roughly appeared on the sea surface of Yueqing Bay between Damen Island and Yuhuan.

"The inspectors from the Yuhuan Meteorological Department also took pictures of the scene when they were observing in the direction of the gate of Dongtou." Lu Rui, director of the Dongtou District Meteorological Observatory, told reporters that the "dragon water absorption" is an extreme event that occurs locally for a short period of time. There are currently no corresponding means and equipment to monitor the weather, and we mainly rely on the masses to report their findings. "'Dragon sucking water' is very rare in Dongtou waters. I have worked in the meteorological department for 10 years, and this is the first time I have encountered it."

Lu Rui said that "dragon water absorption" is a strong convective weather phenomenon, which is usually easily induced when thunderstorms and strong winds occur in the surrounding area. "On the day of the incident, there were thunderstorms in Yueqing and Yuhuan around Damen Island, and the waters of Damen Island happened to be in the The edge of thunderstorms. "

Reporters searched public reports and related information and found that the phenomenon of "dragons absorbing water" occasionally occurs in many places in Wenzhou. In September 2008, a citizen photographed a "dragon sucking water" at the Lingni Embankment in Dongtou. In November last year, some netizens posted a video saying that they encountered a "dragon sucking water" in the waters off Beiji Island, Ruian.

Fishing boats that find "dragon sucking water" should turn away from

Data from the Meteorological Publicity and Science Popularization Center of the China Meteorological Administration show that a tornado is a local, small-scale, sudden strong convective weather, which is extremely unstable. Under certain weather conditions, air convection movement causes strong, small-scale air vortices. The space-time scale of a tornado is very small, with a diameter generally less than 100 meters, and the time from occurrence to dissipation ranges from a few minutes to dozens of minutes. When a tornado is on the water, its strong suction will roll up the water, which is what people often call "dragon sucking water", also known as "waterspout". At this time, creatures in the water may also be rolled up. When the "dragon absorbs water" lands, due to the increase in friction, the centripetal force weakens, resulting in the so-called "fish rain" or "seafood rain".

"'Dragon sucking water' exists for a short time, and the area affected is very small. It is generally not easy to cause much impact at sea." Lu Rui said that if fishing boats find "dragon sucking water" at sea, they should turn away. If you encounter a tornado on land, you should flee in a direction perpendicular to the direction of the tornado's movement. If it is too late, quickly find a depression and lie down, but stay away from large trees, telephone poles, billboards, walls and other objects that can be easily blown down and injure people.
