Low tide schedule of Chen Gang seaside in 2022

The tide ebbs between nine and ten in the morning.

The reason of low tide is related to both the moon and the sun, that is, the tidal force that is often heard comes from the attraction of the moon and the sun to the earth. Tidal force is an integral force, which is not completely determined by gravity.

But because the earth is so big, the magnitude and direction of gravity borne by different parts of the earth are not exactly the same, and there are "force difference" and "direction difference", which are two differences in tidal force.

Note: The fluctuation of seawater is regular. If we master the law of tidal fluctuation time, it can bring a lot of convenience to people's daily production and life. There is a way to calculate and master the time of daily tidal fluctuation.

Take Qingdao as an example. The sea area near Qingdao is a regular semidiurnal tide. According to the normal semidiurnal tide, the period of each tidal activity is 12.4 hours, which fluctuates twice a day.
