Survival on the Island starts with a female boss

Chapter 91 Premonition of typhoon coming

I saw swells and waves rolling on the sea surface, and the waves were no longer the sharp waves before.

It is a round wave, not too high, and the distance between the waves is not as close as it was when the sea was calm.

There is a distance of hundreds of meters between each wave, and the height of the waves is not as high as that of the giant waves. According to visual estimation, it is at most one or two meters high.

However, the momentum of such a low wave was particularly astonishing, and there were waves of deep roars.

"This should be the swell phenomenon generated by the hurricane."

Yu Tina seems to be talking to herself, and it seems to be giving science to two people.

Ma Yongqiang listened to what Yu Tina said. Ma Yongqiang, who was not very experienced, only understood a message that a hurricane was coming, and he didn't understand a word of the rest of the swell phenomenon.

"Xiaona, what swell are you talking about? Can you explain it to me?
I only understand that you said that a hurricane is coming. Is a hurricane just a whirlwind?Or a tornado?If it's a tornado, let's run quickly! "

Yu Tina rolled her eyes to Ma Yongqiang's face.

"Qiangzi, should I praise you for your ignorance, or should I laugh at your childishness!

It's also fortunate that there are only a few of us here and there are no outsiders, otherwise I would be really embarrassed to tell others that I know you.

Let me tell you, remember it!Don't make jokes anymore.

A hurricane is the academic name for a strong typhoon, but it’s not, the tornado and whirlwind you think, if you go out like this, you can really laugh your teeth out.

There are also ordinary waves and long waves.

Long waves are also called swells.When the typhoon is still far away on the ocean, a special wave can be seen propagating from the center of the typhoon at the seaside.

The top of the wave is round, the wave head is not high (usually only one or two meters high), and the distance between the wave head and the wave head is relatively long, which is different from ordinary peaks and short-distance waves.

The long waves look round, have a heavy sound, and a slow rhythm, spreading about 70-80 kilometers per hour.When this kind of wave approaches the coast, it will turn into rolling broken waves, which often raise the water level of the coast and make the waves rough. This is the meaning of "long waves rise without wind, and soon the strong wind will fall".

And look over there! "

After Yu Tina finished speaking, she pointed to the distance of the sea.

Yu Tina's loss almost directly referred to Ma Yongqiang as autistic. Fortunately, Ma Yongqiang had a thick skin, and he was still a woman talking about himself. look in the direction of
Ma Yongqiang tried his best to find that there were several black spots floating in mid-air above the sea in the distance, which seemed to be very strenuous, and there was another black spot, which seemed to be swallowed by the waves in an instant after falling into the sea accidentally. up.

"Sister Nana, it looks like a seabird flying in the sky! But why did it suddenly fall into the sea?"

Feng Yali asked Ma Yongqiang ahead of her doubts.

Ma Yongqiang also nodded in agreement, also expressing his lack of understanding in his heart.

Yu Tina thought for a while in her heart, thought for a while, and then explained.

"According to some books and folk magazines, when a typhoon comes, various visions will appear in the sky
An experience of coastal fisherman forecasting stations based on sky phenomena.When the center of the typhoon is about five or six hundred kilometers away from the coast.

Coastal fishermen can see that there are light clouds like messy threads scattered in the eastern sky, spreading out from the horizon like a fan (this is called converging cirrus in meteorology), and there will be beautiful rainbows in the sky in the morning or evening .

The masses call it "Taimu", which means that seeing this kind of clouds means that a typhoon is coming.

In addition, before the typhoon comes, the rainbow in the sky will also appear strange.

There is a proverb among the fishermen along the coast of Fujian and Guangdong, "When the rainbow breaks down, the sky will change".This "heaven will change" means that the typhoon will hit and bring violent wind and rain.

Broken rainbow, also known as short rainbow, is a half-cut rainbow that appears on the southeast sea.It does not have the solitary bends of common rainbows, nor is it brightly colored, and it usually appears at dusk.

Because the broken rainbow is formed by the refraction of sunlight by water droplets in the low air around the typhoon, seeing the broken rainbow indicates that the typhoon is not far away.

There is also the phenomenon of seabirds landing. Before the arrival of the typhoon, large groups of seabirds can be seen flying towards the land in a hurry.

Sometimes the birds are so exhausted that they fall on the ship or on the sea, or even rest on the deck in groups, and refuse to leave no matter how you drive them away.

Just now we saw those black dots falling into the sea. It should be that the birds in the air were too tired to fly and had no place to rest, so they fell into the sea. "

Ma Yongqiang and Feng Yali were also deeply shocked after listening to Yu Tina's well-founded explanation.

I have to say that things in the world are really strange. Yu Tina, who grew up in the city, basically has no survival skills in the wild.

I happened to meet Ma Yongqiang and Feng Yali, two children who grew up in the countryside. Children who grew up in the countryside often don't have that comprehensive knowledge, but they have very strong hands-on ability.
