Recently, a "dragon sucking water" appeared on the sea near Haikou, Hainan, and the scene was spectacular.
The video shot by a mobile phone shows that at noon on October 27, the sky was half-dark and half-dark, and a "dragon sucking water" appeared between the sea and the sky, connecting the sky above and the sea below, and moving on the sea.
Li Yumei, chief forecaster of the Hainan Provincial Meteorological Observatory: Because the cold air in the north is gradually pressing southward, the south will still be affected by the relatively warm and humid southeast airflow on the 27th. Therefore, the intersection of the two air currents can easily produce this kind of relatively strong weather.
According to reports, "dragon sucking water" is actually a tornado that occurs on the water. It usually appears on warm water and is a violent local weather phenomenon.
In places where the temperature of the water surface is high, the air heats up significantly, the air pressure decreases rapidly, forming a vortex center, and the water flow is also sucked into the bottom of the vortex. There is a difference in wind speed between the layers, causing the air flow to rise in a vortex, entraining the water flow to become an axial upward vortex.
Sometimes its upper end is connected with thunderstorm clouds, or it may appear far away from the thunderstorm system, turning and moving. These rapidly rotating column-shaped waterspouts are full of water vapor. , as dangerous as a tornado.
Li Yumei, chief forecaster of the Hainan Provincial Meteorological Observatory: If fishing boats are passing by on the sea and you see this "dragon sucking water" phenomenon from a distance, you should try to avoid it. Because the rotating wind force near its center is particularly strong, it will cause the ship to capsize or be damaged.
