Dry tide: 4.00, 15.36. Variation law of tides in high flood season: Due to the gravitational effect of the sun and the moon on the earth, tidal phenomena of seawater fluctuation twice day and night have appeared in most coastal areas of China.

Every month, the first day to the fifth day of the lunar calendar (or the sixteenth to twentieth day of the lunar calendar) is the spring tide (called "the flood season" locally); The sixth to twelfth day of the sixth lunar month (or the 21st to 25th lunar month) is a small tide (called "dead tide" locally); The ninth or 24th day is the minimum tide (called "the end of the dead flood season" by local people). Every day, the tidal time is delayed by about 45 minutes, and so on. I hope friends who go to the seaside can refer to it, which will make you have a better time! .

The time of high tide indicates that the ocean is attracted by the moon. Twice a day. The time is the same in the morning and evening. The next day was postponed for 48 minutes. The date of high tide is the eighteenth day of the lunar calendar and the third day of the third month of the lunar calendar. The tide table is as follows: (referring to the water level time of Xiaguan in Nanjing, Yangtze River) Day 1, Day 2, Day 3, Day 4, Day 5, Day 6, Day 7, Day 8, Day 9, Day 11, Day 23, Day 4 and Day 5 4809: 3610: 24/kloc-0. In addition, lead decreased less. The daily tide situation is roughly like this: it takes about 6 hours from the beginning of high tide to the beginning of low tide. That is, high tide for 2 hours, low tide for 2 hours, and low tide for 2 hours. For example, tomorrow 27th is the second day of the second lunar month. Then according to the tide table, it is 8: 48 in the morning and 20: 48 in the evening. /kloc-The low tide begins at 0/2 and returns to the original water level at 2 o'clock. I don't know if it's right. I haven't checked it on the spot. It's estimated that it's not much difference.

The tide rises and falls. Tide is the most intuitive and vivid display of the moon's gravity. It is easy to understand that the side of the earth near the moon is the most attractive, followed by the central part, and the side facing away from the moon is the smallest. This difference in gravity tends to flatten and lengthen the earth. Therefore, two water mounds are raised simultaneously on the side facing the moon and the side facing away from the moon. Due to the rotation of the earth, after the earth is connected with the moon, two water mounds opposite to each other are constantly moving. The tide formed. Because the much heavier sun is far away, the tidal force is only one-third of that of the moon. When the sun, the moon and the earth are in the same line, the superposition effect will make the tide reach the maximum. In fact, as an elastic body, the earth's lithosphere also has solid tides. However, the deformation range is not large, and the "tidal peak" is only about 70 cm, which is not easy to be detected and perceived at ordinary times. There are also changes in atmospheric flow and pressure caused by tides. The most profound influence of tidal action on the earth is that the friction of seawater flow, the impact on the coast and the deformation of the lithosphere all hinder the rotation of the earth and act as a pair of "brake pads". Although this force is very small, it will only slow down the earth's rotation for 2 seconds in 654.38+ million years. However, we have to marvel at the result of the long "time lever" again. 10.6 billion years ago, the earth had only nine hours every day and night, and there were more than 800 days in a year. 600 million years ago, it was 20 hours a day and 440 days a year. The fossil growth line of submarine corals has left an ancient time scale. Imagine that year, a huge tide much higher than today rushed to the coast. Obviously, life landed on the earth from the cradle of the ocean because of the urging and carrying of the tides. The ancient moon was much closer to us than it is now. As the earth's rotation slows down, the moon also follows the law of conservation of angular momentum, drifting at a speed of 3 cm per year. Conversely, the earth's solid tide on the moon has also brought about the "rotation stall" of the moon. The moon will not be stable until it faces the earth forever. Speaking of tidal force, the earth will always face the moon. This will take at least billions of years. The tide is very punctual, almost as accurate as a clock. The moon orbits the earth for 24 hours and 48 minutes, and the cycle of tides is also 24 hours and 48 minutes. During the day and at night, most of the sea water looks like the moon once, and once with its back to the moon, the sea water naturally fluctuates twice. We know that the moon plays a leading role in tidal phenomena, but we can't ignore the influence of the sun. When the moon, the earth and the sun are at right angles, the tidal force of the moon and the sun cancel each other out, and the fluctuation gap of the sea surface is very small, which is a small tide. When the sun, the moon and the earth are in a straight line, the tidal force of the moon and the tidal force of Sun Qixin work together, and the tidal force is large, which is the spring tide. In the seasons of spring equinox and autumn equinox, the earth is closest to the sun, and with the help of the moon, special tides are formed. It happens at the autumnal equinox. Every time the tide rises, the Qiantang River will set off huge waves, such as Ma Benteng, which is breathtaking and spectacular. Tidal changes directly affect people's lives, such as military affairs, ocean navigation, offshore fishing, mariculture, ocean engineering and various coastal production activities. In order to master the laws of tides, the research on tides has never stopped. There are many large and small ocean stations along the coast of China. These ocean stations record local tidal conditions and tidal level changes at any time, and transmit these information to the National Ocean Information Center in time and accurately. According to this information, experts in marine information make analysis and calculation, and make tidal schedules of China and major ports in the world, so that they can be known three years in advance for use by various power generation departments. There is still huge energy in the tide, and tidal power generation is realized by the difference of tides. At present, more than ten tidal power stations have been built in China, and the Jiangxia tidal power station built in 1980 can generate 1070000 kwh per year. Because tidal power stations neither waste energy nor pollute the environment, they bring infinite light and benefits to people.

The tidal level rises to the highest at 6: 00 a.m. and at 8: 00 p.m. on the first and fifteenth day of each lunar month, and drops to the lowest at noon 12:00 a.m. and 0:00 a.m. Then the time of high tide and low tide is delayed for 48 minutes every day.

The law of seawater fluctuation is: there are two high tides every day, with an interval of 12 hours.

The high tide generally lasts for more than an hour before the low tide begins, and the low tide time is at least between the two high tides. The time of high tide is different every day, and it is repeated every 15 days. Therefore, the climax of the next day was delayed by 0.8 hours (48 minutes) compared with the previous day. The daily high tide time can be calculated according to the lunar calendar date, and the calculation formula is as follows: the high tide time from the first day to the fifteenth day of the lunar calendar = date * 0.8; Lunar calendar 16 to 30 high tide time = (date-15)*0.8.

Tidal phenomena can be regarded as the superposition of tidal components in many different periods, so the tidal height at any moment can be expressed as the height of the average sea level on the tidal height datum, the circumferential frequency of the tidal components, and the intersection factor. D is the astronomical phase angle at the beginning of Greenwich, and H is the harmonic constant of the tidal components-amplitude and lag angle. In this way, the tidal harmonic constant of the port can be calculated, and then the tidal time and height of high tide and low tide and the tidal height of the hour can be calculated, and the daily forecast table can be made.

The extended data in tide tables are usually accompanied by graphs and tables that are convenient for calculation, and are used to calculate the tide level at any time between high tide and low tide or at any time when any tide level appears when high tide and low tide are known. In addition, some tide tables are accompanied by the harmonic constants of the main tidal components in each port, or briefly introduce the tidal current in the nearby waters.

Refer to the tide table.

What is the daily schedule of the ebb and flow of the tide? The daily tide table is the specific time when the tide rises and falls.

The tidal level rises to the highest at 6: 00 a.m. and at 8: 00 p.m. on the first and fifteenth day of each lunar month, and drops to the lowest at noon 12:00 a.m. and 0:00 a.m. Then the time of high tide and low tide is delayed for 48 minutes every day.

The ebb and flow of tides are regular and timely. Each cycle of high tide is 24 hours and 50 minutes.

The time and law of each month and year are as follows: there are two spring tides every month, the time is the first day and the fifteenth day respectively; There are also two small tides, the seventh day and the twenty-second day. And on the 9th and 23rd of every month, it rises at noon in the morning and evening.

The vernal equinox and autumnal equinox are spring tides in a year; The solstice in summer and the solstice in winter are small tides. Extended data:

Simple calculation method of tidal fluctuation time Because the tide of seawater is a geographical phenomenon influenced by the gravity of the moon, the tidal fluctuation is regular, with a period of 15 days. So the high tide was delayed by 0.8 hours the next day.

The daily high tide time can be calculated according to the lunar calendar date. The simple calculation method of high tide time is: high tide time = lunar calendar *0.8, low tide time = high tide time plus or minus 6 hours. Suppose: today is 15 of the lunar calendar, and the highest climax time is = 15*0.8= 12, that is,12 at noon and midnight; The lowest ebb time is 6 am and 6 pm.

Close observation time is from 4: 00 am to 8: 00 am and from 4: 00 pm to 8: 00 pm. References:

Bohai Bay Tide Table Note: 1, this tide table is the lunar calendar date.

2, * is the time before the first orgasm. Tidal variation law: Due to the gravitational effect of the sun and the moon on the earth, most coastal areas in China have tidal phenomena of seawater fluctuation twice day and night.

Every month, the first day to the fifth day of the lunar calendar (or the sixteenth to twentieth day of the lunar calendar) is the spring tide (called "the flood season" locally); The sixth to twelfth day of the sixth lunar month (or the 21st to 25th lunar month) is a small tide (called "dead tide" locally); The ninth or 24th day is the minimum tide (called "the end of the dead flood season" by local people). The tidal time is delayed by about 45 minutes every day, and so on.

The formula is: the first day of the first year, the fifteenth day, these two days at noon 12, the eighth day, the 24th day, six o'clock in the morning and six o'clock in the evening, and so on, with a delay of 40 minutes every day.
