Dangerous waves by the sea

Dangerous waves at the seaside, people may be swept away silently when swimming in the sea. Everyone should have heard that the sea is beautiful, but it is not completely harmless to us. Let's learn about the dangerous waves by the sea.

Dangerous waves at the seaside 1 The seaside has always been a place that many people yearn for, especially some inland residents have an illusion about the sea, so they will choose to go to the island for vacation whenever they have time. So many island countries are also very popular, such as Thailand, Maldives, Australia's Gold Coast and Hawaii Beach. French Lille may be unfamiliar to everyone, but it is actually a very popular hot spot in France.

A French donkey friend has never heard of this place before, because to be honest, few people will know about this island if they are not locals. It is also a coincidence that the donkey friends didn't know about this island until they arrived in France. It is said that "strange" waves often appear on this island of Riel. So I went to this island with my local companions. This island is really beautiful. The donkey friends heard from their companions that the island is not particularly big, about 3 miles wide and 19 miles long. The ocean is blue, the sand on the beach is crystal soft, and there are lighthouses.

In fact, the waves on Riel Island are "strange" because my companions and friends have said that they have heard that the waves of this sea do not rush directly to the shore like most waves, but present a square, just like a chessboard, which will be more obvious if you stand on a lighthouse. At first, this wonderful phenomenon attracted many tourists present. They all thought it was a miracle, so they all went to take pictures as a souvenir. But I didn't expect this strange square wave to suddenly roll up, and the height was as high as several meters, which swept the tourists who were originally close to each other into the sea. Fortunately, the degree caused was not particularly serious, and all the tourists involved in the sea were rescued ashore.

Although this kind of wave is really rare in the world, if it is found, the companion tells the donkey friend that it is really a dangerous ocean phenomenon, which is worse than the rapids. The donkey friend asked his companion what caused the "square wave". The companion explained that this was actually caused by extreme weather patterns. Two different weather patterns make the sea water form two different directions, and once they meet, it presents a cross, which is the square you see. But being in the water is a complete disaster. Needless to say, the tide is fierce and moving very fast. Many people will be caught in the water before they know it. If you panic, the water quality will be poor and the consequences will be unimaginable.

Fortunately, such dangerous waves don't often appear, so sometimes it is safer to swim in the waters near the island. However, it is precisely because of the "square wave" that many people are still curious about Riel Island, just like the donkey friends who come to watch it. Locals often tell tourists that when they see a square wave, they can't take pictures wholeheartedly.

I think the sea has always given people a gentle and beautiful feeling, but in fact, the sea also has a fierce side, especially in bad weather, this happy place for tourists to spend the summer will suddenly become a terrible "devil" that devours everything. Especially now that the weather is getting hotter and hotter, everyone will definitely like to go to the seaside to play, but at the same time, we should pay attention to safety. If the weather changes or the current is abnormal, it is best to leave as soon as possible.

In fact, many people don't know about the dangerous waves by the sea. It's just that when you meet them, if there is no right way, maybe you just drift with the tide and disappear into the waves, and you die. This wave is a split current. It is said that 80% of drowning incidents in the United States are caused by rip flow, because this rip flow is still very powerful, sometimes pulling lifeboats into the sea.

In fact, the occurrence of rip current is random, sometimes lasting for several days, sometimes lasting for several minutes, but it is more important to know what rip current is, so as to nip in the bud. Generally speaking, rip flow will bring a lot of sediment back to the sea, so if you find a wave coming, the middle wave is a little yellow, which is more yellow than the waves on both sides, then you should pay attention to this, which may be rip flow, because rip flow is the seawater floating directly back to the sea.

Besides, look at the waves. Generally speaking, there is no Bai Bo in rip stream. If there are white waves on both sides of the wave, if there are no yellow waves coming towards you, then you should pay attention. Don't go back at this time, because your speed cannot escape the speed of rip current. At this time, you must remember that the beach is parallel. Only in this way can we deviate from the place where the crevasse passes and not be brought into the sea by the crevasse.

Therefore, when traveling, you must learn some self-help knowledge. Sometimes, this self-help knowledge can save your life. Parents who take their children to the seaside or swimming pool must always look after their children, because it is possible that your children may be separated from you because of carelessness or seeing a circle of friends. If so, it's too late to regret it.

Dangerous waves by the sea will kill you. If you drown, you drown This old saying has a deep understanding for us who are at the seaside all the year round. Every year, there are dangerous tourists on the beach. Through understanding, they are basically tourists who can swim. So I'm here to tell you that whether you can swim on the beach or not, you should have a sense of safety protection and don't swim in the depths of the sea.

At the same time, there was a sudden danger and the beach was equipped with a rescue team. Please shout for help and get everyone's attention! As shown in the picture below, if you see such "fault waves" while playing in the sea, you should go ashore immediately, because this is a place where waves and eddies are very easy to appear.

But if you are already in a whirlpool, first of all, don't think about swimming back to the shore. All you can do is swim parallel to the coastline, which is the only way to save yourself.

The technical term of fault wave is split flow, also known as "split flow", which is the biggest safety threat for tourists when they play at the seaside. According to long-term research in Brazil and Australia, about 90% of drowning at the seaside is caused by tearing flow. Tearing current is a strong current that flows rapidly to the open sea. Because it will take people away from the shore and drift to the open sea, it is easy for people to run out of energy and drown when confronting it.

Rip current will suddenly appear when people are unprepared, and it may happen under any weather conditions. It will appear on many types of beaches. Unlike waves that make a lot of noise due to violent impact, rip current will not attract people's attention until people are trapped in it.

So how to identify rip current? The bottom of the rip stream is lower than the two sides, and the white waves on the sea surface rush to the shore, as if it were a high tide; But the blue water under the sea flows into the middle of the sea, which seems to be ebbing. Because the rip flow is deep water, most of the colors are dark. Moreover, some tear flow surfaces seem to have almost no waves. Compared with the surrounding white waves and swells, they are quiet, which can easily fool swimmers.

How to save yourself when you meet rip current? The swimming speed of typical rip current is about 2m/s, which exceeds the swimming speed of ordinary people. Rip current has a fast flow rate and a narrow flow range, so not only ordinary swimmers but also lifeguards are often pulled out to sea by it during training.

1. When the rapids are raging, don't choose to fight against nature, don't try to swim back to the shore against the current, but keep calm, step on the water or float with the least effort, call for help or wave for help.

2. Don't panic or struggle. Drift with the current, along the direction of the water in the rip stream, parallel to the beach, and then turn back to the shore after leaving the rip stream.

3. If you meet the victims trapped in the rapids, try to help them float, and don't rush into the water for rescue!

Accidents always come at once, and no one can think of them! So be careful when playing in the water by the sea! Besides choosing beaches where lifeguards are stationed, we should also pay more attention to the waves and weather changes, which is fun and safe!
