A rare tidal phenomenon in the form of fish scales
ArabiaWeather - We recently witnessed a unique and exciting natural event on the banks of the Qiantang River in Zhejiang Province, China. This phenomenon is known as the “Silver Dragon” or the “Fish Scales Phenomenon.” It has aroused great attention and received widespread reports. So what is this phenomenon? How does it happen?
The phenomenon of extending fish scales or the silver dragon
The phenomenon of fish scales occurs as a result of a change in water levels, which leads to the formation of large waves resembling fish scales that arise on the surface of the water. The Qiantang River, located in Zhejiang Province in eastern China, is known for its large flow. It witnessed an unusual tide, and this phenomenon was recorded for the first time in 2021 during a trip. Scientific exploration on the Qiantang River during high tide.
How does the phenomenon of fish scales occur?
Tidal phenomenon "fish scales" occurs when two sets of waves generated by the tidal movement overlap at oblique angles; This creates an enchanting and complex visual pattern. This event can be described as resembling a crisscross sea state where two wave systems move at oblique angles, resembling a unique and stunning formation on the surface of the water.
It is worth noting that the Qiantang River and its mouth, Hangzhou Bay, contain the largest tidal cavities in the world, with waves reaching 9 meters in height in some places. This means that this area often witnesses huge waves moving against the natural current, and the area is also known for its currents. Rotor which enables it to change the direction of flow during the tidal cycle without a change in speed.
Cameras in some neighborhoods of the eastern Zhejiang Province in China recorded amazing and wonderful footage, as the phenomenon of tidal surge in the Qiantang River reached its highest levels on Monday, October 2 .
The Qiantang River is considered one of the most prominent sites that witness tidal surges globally, and is known locally as the “Silver Dragon.” This phenomenon is caused by the influence of the moon's gravity. Hangzhou Bay in Zhejiang Province, China, provides easy access to the tide, but is difficult to recede, creating this magnificent sea swell.
