After getting up early the next morning, Qin Shiou, who was going to exercise, knew why the fishermen had such a pleasant discussion last night.

Normally, from a month’s perspective, during a new or full moon, the sun and the moon exert gravitational forces in the same direction or in opposite directions, resulting in a high tide; but when the first or last quarter, the gravitational action of the moon opposes the gravitational action of the sun. The producer has a low ebb, and each cycle is about half a month.

  From a year's perspective, there are also two high and low tides.

   At the spring and autumn equinox, if the earth, moon and sun are almost on the same plane, the tidal force at this time is greater than that of other months, causing two high tides in spring and autumn in the year.

  At other times, the tides are not very big, and they can’t even be felt at ordinary times.

  But there are exceptions to everything. The size of the tides has a lot to do with the distance of the moon and the sun from the earth.

As we all know, the orbit of the moon is an ellipse. It is close to and away from the earth about once a month or so. The near-earth tide is 39% larger than the far-earth tide. When the near-earth tide coincides with the high tide, the tidal range is particularly large. When the tide coincides with the low tide, the tidal range is particularly small.

  Similarly, the earth's orbit around the sun is also an ellipse. At the perihelion, the sun has a strong gravitational force, and the tide is strong, while at the aphelion, the gravitational force is small, and the tide is weak.

To put it simply, if the position of the earth appears at the nearest point of the moon’s orbit on a certain day, and it happens to be close to the sun, that is, when the sun, the moon, and the earth are almost in a straight line, the seawater will receive the greatest tidal force on that day. , The most powerful tide will reveal its true face.

  This huge tide started today.

  The tide started to ebb in the early hours of the morning, waiting for Qin Shiou to run to the beach during morning exercises. Seeing that the sea has withdrawn far away, the thick and solid stone pillars under the high-piled wharf are exposed.

  The sea receded, exposing the former seabed.

  The fishing grounds are full of reefs, and these reefs are uneven. It was covered with seaweed, seaweed, and aquatic plants that did not leave with the tide. In addition, there were a lot of fish, shrimp and crabs on the beach.

  A large area of ​​reddish-brown reefs appeared on the beach. It has been a long time since they were seen again. The texture of the bottom of the Daqin Fishery is very good, and it is full of sand. Qin Shiou could run over in sports shoes, and he took a piece of reef away, and a few small crabs appeared underneath.

  Beside the reef, four or five smelt fish were jumping around in difficulty. They were not dead yet, and they were lingering on the sea water attached to the seaweed next to them.

  In addition to the smelt, there were bright silver herrings around, and the tiger picked up one and shook his head. When Bush flew down, he raised his head and flew the fish up. Bush accurately probed the fish and bit the fish into his mouth.

Xiong Da yawned and ran over, and when he saw so many fish on the beach, he suddenly lost his joy, especially the salmon did not return to the sea in time with the tide and stayed on the beach. This is brown bear eyes. The supreme deliciousness in it.

  Qin Shiou played with the little guys here. Winnie called him to have breakfast. After he returned, Shirley and the others went downstairs, wearing slippers and the like, ready to pick up fish and scallops.

  Duo Duo followed Shirley like a little tail, her hands tightly holding Shirley's skirt, Qin Shiou waved to her, she smiled sweetly and nodded vigorously at him.

  Qin Shiou handed the small cup of milk juice to Duo Duo, and Duo Duo pecked his hand with a probe, but she could not speak. You can only express your feelings with actions. Most people don't understand sign language, so she uses kissing gestures to people she likes.

  Vini hugged Duo Duo onto the stool, and a few small chinchillas rolled in like fur balls, looking for fruit peels. Blossoming looked at them curiously. The little ground squirrels raised their heads and stared at Duo with their small, dark, round eyes curiously.

  Vini divides an apple into five parts and gives it to the little chinchilla brothers. They hugged the apple while eating while continuing to look at the blossoms, their mouths propped up, and they squirmed quickly and looked cute.

  "I forgot to introduce Duo Duo to the little ground squirrel family." Qin Shiou smiled, he hugged Duo Duo, and Duo Duo immediately squatted on the ground and stretched out his hand to try and pet the little ground squirrel.

  The little yellow squirrel didn't avoid it, turned to look at her, and continued to eat his share of apples quickly.

Duoduo unfolded the left hand she had been holding, and there were a few blackberries in it. She handed her small hand to the little yellow squirrel. The little yellow mouse looked at the blackberry blankly, and decisively gave half of her apple to Duo. Replaced with delicious and juicy blackberries.

  Mao Weilong and Liu Shuyan also walked down behind. Seeing Duo Duo and the little ground squirrel having fun together, Liu Shuyan nodded and smiled at Qin Shiou: "Thank you for taking care of Duo Duo."

  Qin Shiou smiled and said, "What kind of care is this? The little girl is making friends by herself. Come on, let's eat. After dinner, we can go to the beach to pick some fish."

  Hearing this, Shirley and Gordon shouted: "Qin, we are not going to school anymore, shall we also pick fish at home?"

   "Yes, I saw from the window just now that a lot of fish and prawns in our fishing grounds are on the beach, which must be more than the fishing grounds in the town." Michelle said.

  Qin Shiou patted the table and asked them to eat their own food quickly, and said, “It’s okay to stay, but you have to be optimistic about sister Duoduo, understand?”

  The conditions were quickly reached, and the children ate their breakfast at an unprecedented speed and hopped out.

  Duo Duo hurriedly drank the juice in his cup, leaped on a stool to chase behind, ran a few steps and thought about it, then came back to bring the little chinchillas.

Qin Shiou yelled, Shirley remembered the conditions just now, and hurried back to pull Duo Duo. Duo Duo pointed to the little ground squirrels behind her with an anxious look. Shirley called Gordon back and asked him and Powell to take the little ground squirrels. .

   "What do you take them for?" Gordon asked unwillingly.

   Shirley frowned and said, "Are your ears itchy?"

   Gordon shrank his neck and quickly sneered: "But you can bring it with you."

One morning, Xiong Da ran happily on the beach, with a fat face squeezed together happily, with a silver scale salmon in its mouth, and a half-large Atlantic salmon in its paws. Fish, Da Bai followed it, pressing a red salmon.

  The children ran into the reef area, and the first thing they picked was naturally the big fish.

  Long coastline, the sea has receded at least two or three hundred meters. On the vacant beach, reefs can be seen everywhere, and stranded fish and shrimps are everywhere.

  The lushness of the fishing grounds was vividly displayed in the eyes of everyone at this moment, and the fishermen who came from behind said with emotion: "It has been more than ten years. The first time I saw so many fish when the tide was low."

  Shaq drove a pickup truck and pulled some incubators over. There were ice cubes in the boxes. The collected valuable fish were put into them. They will be sold in the future.

  Several children came up and dragged an incubator and ran into the bottom of the reef happily. Winnie shouted, “Be careful, don’t take off your shoes. Do you understand that there are many broken stones?”

  The children waved their hands without looking back to indicate that they knew. As for them, God only knew. (To be continued~^~)
