Tidal fluctuation table of Donggang

The tidal fluctuation schedule of Donggang is as follows:

The fluctuation of seawater during the day is called tide, and the fluctuation at night is called sunseeker, so the fluctuation of seawater is also called tide. Tidal phenomenon refers to the periodic movement of seawater under the tidal force of celestial bodies (mainly the moon and the sun).

Because the relative positions of the earth, the moon and the sun change periodically, the role of this force also changes periodically. As a result, this periodic tidal phenomenon appeared in front of people.

Expanding knowledge-tidal phenomenon;

Tidal phenomenon refers to the periodic movement of seawater under the tidal force of celestial bodies (mainly the moon and the sun). With the periodic changes of the relative positions of the earth, the moon and the sun, the role of this force also changes periodically. As a result, this periodic tidal phenomenon appeared in front of people.

When the tide rises, the tide level keeps rising. After reaching a certain height, the tide level does not rise or retreat for a short time, which is called flat tide, and the middle time of flat tide is called high tide. The duration of flat tide varies from place to place, ranging from several minutes to dozens of minutes. After the flat tide, the tide level began to fall.

When the tide level recedes to the lowest level, similar to the normal tide level, there is also a phenomenon that the tide level does not retreat or rise, which is called tide stop, and the middle time is low tide.

After the tide stopped, the tide level began to rise again, so it moved again and again. The interval from low tide to high tide is called high tide, and the interval from high tide to low tide is called low tide.

Generally speaking, in many places, the high tide is not as long as the low tide. The height when the sea surface rises to the highest position is called high tide, the height when it falls to the lowest position is called low tide, and the difference between adjacent high tides and low tides is called tidal range.
