The cold wave has long been common to mankind. Even now, after the whole world has been frozen, the cold wave will occur several times a year in recent years.

Although the arrival of each cold wave will lower the already low temperature again, even close to the limit of minus 100 degrees, for Yanguo, in addition to being in a hurry for the first time, after several times, the cold wave is the same for Yanguo.

After all, with the help of Chen Xin, a person who opened and hung the energy tower, the black technology heating equipment makes Yanguo not worry about the impact of the cold wave.

Especially when the snow is getting thicker and cannot melt because of the cold weather, they even isolate the colder temperature of the outside world to some extent.

This is somewhat similar to the Inuit igloo. As long as the internal temperature is maintained and the heat is not lost, for humans, the cold wave is just a short-term bad weather that can't go out and must stay indoors.

However, this cold wave is somewhat different.

Not only did the cold wave move southward faster than expected, but also because the previous thunderstorm test formed a storm in the Dongting Lake area.

Thunderstorm itself belongs to a kind of extremely bad weather. Thunderstorm produced by weather controller also accumulates energy in the air by means of local heating, and then releases positive and negative charges by guiding air friction.

According to the original plan of Chen Xin, meteorologists and physicists, thunderstorms should dissipate naturally after the test is suspended, and will not bring subsequent adverse effects.

Even if the temperature rise in some areas will have some impact on the weather, it will not be very serious.

However, when the cold wave heading south suddenly accelerates and will reach the Dongting Lake area within a few hours, everything becomes different.

As we all know, when cold air and hot air meet, various weather phenomena will occur under the alternation of cold and hot.

One of the manifestations is that the air pressure decreases rapidly in a short time, resulting in drastic changes in the weather.

This phenomenon is called Bomb cyclone, which is usually seen in North America. The cause is that the warm and humid air meets the cold air, causing a rapid drop in air pressure in a short time, resulting in extreme weather.

In the famous disaster film the day after tomorrow, such a scene also appears.

A huge hole is formed in the clouds, just like a typhoon eye. The colder air in the upper atmosphere is sucked to the ground because of the rapid decline of air pressure, and everything is frozen in an instant.

Now, as the cold wave heading south meets the warm air over the East Dongting Lake area caused by thunderstorms, an extremely violent bomb cyclone is forming.

Even the most experienced meteorologists cannot predict what terrible damage this low-pressure system will bring. After all, mankind has never seen what will happen when cold air close to minus 100 degrees meets hot air of more than a dozen degrees.

Since the birth of mankind and the formation of civilization, the entire Blue Star atmospheric circulation system has actually been relatively stable.

Although there will be some bad weather, it has not produced too extreme weather phenomena.

But this time, mankind will see what may be the most terrible weather phenomenon in human history.

Because it's dawn.

"With the formation of this low pressure system, a large amount of high-rise air is sucked to the ground. This gradually formed pressure system is now like a huge vacuum cleaner to wash the air in the sky and the dust and particles in the air." the meteorologist pointed to the picture taken on the big screen and explained to the people around him: "Because these dust and particles are absorbed to the ground, the originally blocked sunlight loses its obstruction, and naturally it can shine on the ground."

"The thunderstorm test artificially created a heating mass in the air. With the stop of the test, the heating mass lost energy supplement. Coupled with the cold wave and cold air going south, the temperature began to decrease rapidly, resulting in the air flow from top to bottom, so this low-pressure system was formed. Am I right?" After listening to the physicist, Chen Xin asked him the reason for the formation of this low-pressure system.

The meteorologist nodded and still didn't forget to add: "the principle is true, but this time the low-pressure system formed too fast! And the cooling range is too large, so it can cause such a terrible phenomenon."

As he spoke, he did not forget to look at the gradually forming and brighter hole on the big screen.

The picture on the big screen was taken in the eyes of the wind formed by the low-pressure system. Here, a thick layer of dust has fallen on the ground, which has become gray black under the long lost sunlight, and the sky is gradually changing from dim yellow to clear.

Although it was a rare blue sky and sunshine, none of the people present had a smile on their face or felt happy about it.

Because all this happened in just half an hour, and with the formation of the cyclone, the cold visible to the naked eye is coming.

In the cyclone shrouded area, as the upper atmosphere is gradually sucked down to the ground, the ambient temperature is also decreasing sharply, because a layer of frost is rapidly forming on the gray black ground where dust falls.

Although the picture on the big screen shows a calm and calm, it seems that even a leaf will not be blown up.

But everyone looking at the big screen knows that this is only the center of the cyclone, similar to the existence of the typhoon eye. The faster it forms, the stronger the wind outside.

For human beings, we have never observed what happens when the air of minus 100 degrees meets the air of above zero temperature.

However, according to the meteorological data currently available to mankind, the faster the temperature decreases and the faster the cyclone forms, the more violent the storm brought by the low-pressure system. Obviously, an unprecedented violent storm is gradually taking shape.

"Have all the soldiers on the defense line done their protective work? The storm may be more violent than we thought, so we must do a good job in response." looking at the blue sky we haven't seen for several years, Chen Xin's face is about to drip water, and asks the general on one side.

At this time, the general was also very serious and said, "the soldiers on the front line have received orders, and everyone is ready to deal with extreme weather and all kinds of emergencies. I believe our soldiers can deal with such weather."

"That's good, but we still need to remind the soldiers that alien creatures may take this opportunity to launch a large-scale attack." Chen Xin reminded with worry: "humans can't resist this bad weather, but those alien creatures may not be!"
