Vortex formation is caused by changes in the speed and direction of water flow.
When the water flow encounters an obstacle or passes through a small gap, its speed and direction will change. This change will cause the water flow to become unstable. When the flow speed is fast, the water flow forms a rotating vortex, which constitutes the formation of a vortex.
The direction of rotation of the vortex is not fixed. In the Northern Hemisphere, vortices typically spin counterclockwise, while in the Southern Hemisphere, vortices typically spin clockwise. This is due to the effect of the Coriolis force caused by the rotation of the Earth. The Coriolis force is an inertial force that deflects the motion of moving objects to the right, and water flow is no exception.
Although the formation and direction of rotationAlthough vortices may seem mysterious, they are in fact a very common element of natural phenomena. By understanding the formation principle and rotation direction of vortices, we can better understand the movement patterns of water flow and better protect and utilize water resources.
The Wonders of Whirlpools
The spiraling vortices formed when water flows through low areas are whirlpools. Most whirlwinds are intimidating and evoke terrifying associations. Today let's go to different parts of the world and see these strange swirls.
The “Big Horn” and “Sow Spray” in Yuan Chonghuan’s hometown.
Xinma Village, Tianping Town, Teng County, Guangxi, is the hometown of Yuan Chonghuan, a military strategist in the Ming Dynasty. People who come here not only want to pay homage to the past, but also want to see the two strangewhirlpools of the Xunjiang River.
These two strange whirlwinds are called "Big Horn" and the other is called "Sow Spray". "Dajiao" is located on the left side of the middle line of the upper Xunjiang River, and "Sow Spray" is on the right side of the middle line of the lower Xunjiang River. They measure approximately 60 meters. apart.
Local residents have a legend that if a ship is caught in a whirlwind while passing the "Big Horn", objects on board the ship will be thrown out of the "sow jet" in front of it diagonally. Both hot tubs make the sound of killing pigs every day. During the rainy season, the “sow spray” sprays sand every five minutes, reaching a height of two to three meters.
After the ship was swallowed by the "big horn", the cargo floated down from the "sow jet". Experts analyzed that this was probably due to the riverand underground. The swallowed ship and cargo drifted with the underground river. underground river. After traveling a certain distance, she came out of the water at another place.
