Chapter 138: Entering the High Danger Point (Must See Chapter!) ）

(WeChat public account: Lao Wu said, pay attention to get first-hand major news, and some analysis materials of this book.) ）

"We're about to enter the sky above the storm, Professor Qiu, and we're in a bit of a tricky situation."

Qiu Bin asked:

"How far is it to get there?"

The driver pointed to the large dark clouds in front of him and said:

"Soon, now through the lightning zone, you will reach the storm, and out of the storm, you will go straight to the place you said."

"In that case, do you have to go through the Storm Zone to get there? Is there a safer way? You can directly bypass the storm zone and reach the location. ”

The driver frowned, and after a pause, replied:

"Professor Qiu, you may not understand this concept, this storm area is actually a chain reaction."

"Even if I go somewhere else and get around this storm area, it's just a lucky statement, and I won't necessarily encounter some other dangers on the way, even I can't guarantee it."

"Also, if we're lucky, if we go out, it's hard to guarantee that there will be no storm zones anywhere else? Obviously unlikely, maybe get out if you're lucky. ”

"Luck is a really big disparity, it's really not what kind of thing can determine what luck will end up with, everything is unknown."

Everything is unknown, and we can never know what will happen in the future, and we dare not predict it.

Human beings are like that for a lifetime, birth, old age, sickness and death are already things that cannot be changed, since they are already like this, why should we be so pessimistic to face this inhumane life.

The driver smiled indifferently and said:

"Professor Qiu, since it has come to this point, let's go on, I have to fight to the death with my own choice, the matter has become so big, if everything that happened is irreparable, then go on."

Walk down the path you choose, no matter how thorny, difficult, or difficult it is.

At the end of that road, there will still be a beautiful scenery waiting for you there.

And all we can do is to persevere, and always believe in one sentence: persistence is victory, but the way to persist in different fields is different.

The helicopter that the two of them were riding in first came to the lightning zone, and when the helicopter flew halfway to the middle.

The driver seemed to have expected this kind of thing to happen, and hurriedly said to Qiu Bin, who was sitting in the back:

"Professor Qiu, sit tight!"

The driver slammed down on the handlebar, and the handle began to tilt sharply to the side.

A dark cloud began to spread in both directions in the sky.

Just listen to the sound of "boom", the color of the thunder and lightning is a little special, in the thunder and lightning is mixed with a cell, which is light blue, and the outer package is dark blue.

It was the most beautiful of all the lightning bolts in this heavy rain.

And this scenery has also successfully attracted many photography enthusiasts and some photography enthusiasts.

At this time, they often stood on the rooftops of high-rise buildings, and they picked up their cameras to record the scenery despite the wind and rain.

Qiu Bin looked out the window, and many flashing cameras began to take pictures.

In the photo, the distance between the thunder and the helicopter is only a fraction of a second, and if they are fused together, this photo will be even better.

Happily, two lives were successfully saved, and it was a stroke of luck.

The helicopter was much darker in the poorly lit environment, but this phenomenon successfully reflected the beauty and majesty of the sky.

"Wuhu!"

There was a cheer from inside the helicopter, and they managed to dodge the blow of the thunderbolt.

There was only a slight abrasion in the tail part of the helicopter.

This is not the most important thing, the important thing is that they managed to dodge the attack of Thunderbolt!

This is something to celebrate, and they gave up the opportunity to celebrate and began to move on.

Qiu Bin took a big breath and spit it out.

"It's so dangerous, it's almost going to crash."

Driver says:

"Professor Qiu, please hold on to the handles on both sides, it may be a huge challenge to your balance next."

"If you can dodge the thunderbolt, you may not be able to dodge the attack in the storm area, the huge swing will cause injuries to the people in the plane, I don't want you to be hurt, you are my customer, and getting hurt a little is a bad brand for my profession."

"It's possible that I'll be resigned when I go back, but it's worth it."

Qiu Bin grabbed the handles on both sides and said:

"Why?"

"Because I experienced the feeling of carrying a big person, at least I can go out and brag twice, hahaha, it's more interesting to think about."

Gradually, helicopters began to enter the entrance to the storm zone.

The situation in the storm zone is unpredictable, especially when it comes to danger.

I don't know what is going on inside, which is what the two are most worried about.

"Have you ever entered the Storm Zone before?"

And ...... No, it's the first time I've been a driver for so long and I've encountered such an emergency situation, so I'm more worried. ”

The helicopter slowly walked into the storm zone, and the danger began to fall again.

The five helicopters faced the storm zone in front of them, not knowing whether to move immediately.

The captain said to Haibin:

"Old Yu, you are familiar with the situation in these storm areas, and you have dealt with them for many years, is there any way to solve it quickly, time should not be delayed."

Lao Yu put his hand on his forehead, sighed and said:

"At the moment we have five helicopters, if we enter the storm zone at the same time, the situation will become more complicated, although I know the situation in the storm zone somewhat, but I also know the horror in it, who knows who goes in."

Time began to lose minute by minute, and five helicopters had been waiting in place for about 10 minutes.

Within the captain's private call channel.

"Captain, the previous positioning device has begun to move, and it is moving relatively fast, if it drags on, the target is likely to disappear."

The captain couldn't bear it anymore, patted the console in front of him and said:

"I can't wait, I have to do something."

The captain said to the private channel:

"Okay, I see."

Then he switched to the public general channel and said:

"Everyone is on guard! Prepare to enter the storm zone. ”

Unit 3: "Captain, I'm afraid it's a little inappropriate to enter now." ”

Unit 4: "Captain, think twice!" ”

Unit 5: "I'll see it!" Captain, I'll support you. ”

All eyes were instantly on helicopter No. 5.

Unit 5: "When I didn't say it, you continue to ......"

The captain lowered his head, thought for a while, raised his head and said:

"Don't think about it anymore, go in now, if it's a second late, I'm afraid the target will disappear, and then all the work will be lost, I don't want this kind of thing to happen, and I won't let this kind of thing happen, all I do is to be able to find them as soon as possible to ensure the safety of Professor Qiu and the driver."

老於 says:

"Captain, we all know what you mean, let's talk about the next plan."

"Each helicopter is equipped with signal flares for emergency use, once we enter the storm area, once a helicopter breaks away from the team, immediately use signal flares to report the location, remember that the signal in the helicopter will be blocked after entering, and the positioning will disappear directly, our human eyes are not the most sensitive, so we must use signal flares."

"Also, Lao Yu should transfer all your other brothers who have been arranged, and arrange them outside the storm zone in your current location, so that you can welcome us when the time comes."

老於 says:

"Okay, I'll arrange for those four spare helicopters to arrive in a moment."

The measures that should be explained have also been explained, but the captain's heart, which has been beating, is a little unsteady.

"I don't know if it's my delusion, I always feel like something is going to happen, no matter ......"

Five helicopters entered the storm zone at the same time.

And the same is true on Qiu Bin's side.

"So that's what happened in the Storm Zone."

In addition to the dark clouds in the storm area, there are also frequent thunder and lightning strikes and some dark clouds flickering in other corners.

Qiu Bin saw that the driver did not see the world very widely, so he planned to give him a science popularization about what a rain storm is, and another similar topic, a tropical storm, has also become a tropical cyclone.

"These phenomena are only one of the more common phenomena in heavy rains, and thunder and lightning and raindrops have created an environment to create three weather phenomena: thunder, rain, and electricity."

"The storm zone we're coming in in now is the same concept, but there's another phenomenon that's even more powerful, and that's a tropical storm."

The driver wondered:

"What is a tropical storm?"

"Actually, it's what we often call a typhoon."

"There are a total of 4 typhoon formations."

Tropical storms are the most devastating of all natural disasters. Every year hurricanes sweep inland from the ocean. After the strong winds and storms, all that was left was a mess.

A tropical storm is a type of typhoon that has a maximum wind force of 8-9 (17.2-24.4 m/s) at its centre.

"First of all, there must be a wide enough tropical ocean surface that not only requires the surface temperature of the sea to be higher than 26.5 degrees Celsius, but also to exceed this value in a layer of water at a depth of 60 meters."

"The vast ocean surface is a necessary natural environment for the formation of typhoons, because the friction between the air molecules inside the typhoon consumes an average of 3,100-4,000 cal/cm of energy per day, and this huge energy can only be supplied by the latent heat released by the vast tropical ocean."

"In addition, strong winds swirling around tropical cyclones can cause sea water to churn near the center, and even the surface of the ocean can rise upwards at the center of a typhoon with a very low pressure drop, and then spread out in all directions, so that the sea water churns around the center of the typhoon."

"In a typhoon, this churning phenomenon can affect a depth of 60 meters. On the surface of the ocean, where the sea temperature is below 26.5°C, it is difficult to maintain a typhoon due to the lack of heat. ”

"In order to ensure that the sea surface temperature is always above 26.5°C during this churning process, this warm water layer must be about 60 meters thick."

"That's the first point, and there are three more points in it, which sound complicated, but it's still easy to understand."

"The second point: before a typhoon can form, there must be a weak tropical vortex in advance."

"We know that the operation of any machine consumes energy, and this requires an energy source."

"A typhoon is also a "heat engine", which turns there at such a huge scale and speed, to consume a lot of energy, so there must be a source of energy. ”

"The energy of a typhoon comes from water vapor from the tropical oceans."

"In a pre-existing tropical vortex, the air pressure in the vortex is lower than that in the surrounding areas, and the surrounding air carries a large amount of water vapor to the center of the vortex and produces an upward movement within the vortex area; Moist air rises, water vapor condenses, and a huge amount of latent heat of condensation is released to make the typhoon a big machine work. ”

"Therefore, even if there is a high temperature and high humidity of the tropical ocean to supply water vapor, if there is no strong rise in air to produce condensation and release latent heat, the typhoon will not be formed."

"Therefore, the upward movement of the air is an important factor in the formation and maintenance of typhoons. However, it is necessary for the existence of a weak tropical vortex. ”

"Three: There should be a sufficiently large earth-rotation deflection force, because the geostrophic deflection force at the equator is zero, and the poles gradually increase, so the typhoon site is about 5 degrees away from the equator."

As a result of the rotation of the Earth, a force is created that changes the direction of the flow of air, which is called the "Earth's Rotation Deflection Force". ”

"On a rotating Earth, the Earth's rotation makes it difficult for the surrounding air to flow directly into the depression, but instead rotates counterclockwise (in the Northern Hemisphere) along the center of the depression."

"Four: above the weak low pressure, the difference between the wind direction and wind speed between the high and low altitudes should be small."

"In this case, the upper and lower air columns act in unison, and the heat in the upper air tends to accumulate and thus warm."

"Once a cyclone is formed, the ambient air flow above the friction layer will flow along the isobar, and the warming of the upper layers will be further completed. In the area north of 20°N, the climatic conditions have changed, mainly because the upper level winds are very strong, which is not conducive to warming, and typhoons are not easy to appear, and tropical storms continue to strengthen to form typhoons. ”
