Doomsday Bunker Upgrade

The advent of cold waves has long been commonplace for human beings. Even now that the whole world has been frozen, there have been several cold waves every year in recent years.

Although the arrival of each cold wave will lower the already very low temperature again, even approaching the limit of minus one hundred degrees, for Yan Kingdom, except for the first time it was indeed a mess, it has been difficult to deal with it. After a few times, the cold wave was the same for Yan Kingdom.

After all, with the help of Chen Xin, the hacker, and the black-tech heating equipment such as the energy tower, Yan Guo is not worried about the impact of the cold wave.

Especially when the snow is getting thicker and unable to melt because of the cold weather now, they even insulate the colder outside temperature to some extent.

This is somewhat similar to the snow house of the Inuit people. As long as the temperature is maintained inside, the heat does not dissipate. For human beings, the cold wave is just a short period of severe weather that cannot go out and must stay indoors.

This time, however, the cold wave looked a little different.

Not only is the cold wave moving southward faster than expected, but also because the previous thunderstorm experiment formed a storm in the Dongting Lake area.

Thunderstorm itself is a kind of extremely severe weather. The weather controller creates thunderstorms by accumulating energy in the air through local heating, and then releases it by guiding air friction to generate positive and negative charges.

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

Even if there will be some impact on the weather due to the increase in temperature in some areas, 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 be produced under the alternation of cold and heat.

One of the manifestations is that the air pressure drops rapidly in a short period of time, which brings about drastic changes in the weather.

This phenomenon is called a bomb cyclone, which is usually seen in North America. It is caused by the encounter of warm and humid air with cold air, causing a rapid drop in air pressure in a short period of time, resulting in extremely severe weather.

This scene also appeared in the famous disaster movie "The Day After Tomorrow".

A huge hole formed in the clouds, like the eye of a typhoon. The colder air in the upper atmosphere was sucked to the ground due to the rapid drop in air pressure, freezing everything in an instant.

But now, as the southward cold wave meets the warm air generated by thunderstorms over the East Dongting Lake area, an extremely violent bomb cyclone is forming.

Even the most experienced meteorologists cannot predict what kind of terrible damage this low pressure system will bring. After all, human beings have never seen what happens when the cold air close to minus one hundred degrees meets the hot air of more than ten degrees. What.

Since the birth of human beings and the formation of civilization, the atmospheric circulation system of the entire Blue Star has been relatively stable since there were written records.

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

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

Because it's dawn.

"As this low-pressure system builds, large volumes of upper air are sucked to the surface, and this developing pressure system now acts like a giant vacuum cleaner, washing down the sky and airborne dust and particles." Meteorology Pointing to the pictures captured on the big screen, the scientist explained to the people around him: "And because these dust and particles are sucked to the ground, the originally blocked sunlight loses its hindrance, and naturally it can shine on the ground."

"The thunderstorm test artificially created a warm air mass in the sky. With the cessation of the test, the warm air mass lost its energy replenishment. Coupled with the cold wave and cold air going south, the temperature began to drop rapidly, which caused the air flow to flow from top to bottom. This low-pressure system, 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 did not forget to add: "The principle is indeed the same, but this time the low pressure system formed too fast! And the cooling rate was too large, which is why it caused such a terrifying phenomenon."

As he said that, he did not forget to look solemnly at the hole on the big screen that was gradually forming and becoming brighter and brighter.

The pictures on the big screen were captured in the eye of the wind formed by this low-pressure system. The ground here has already been covered with a thick layer of dust, which has turned gray-black under the long-lost sunlight. The sky is gradually changing from hazy to clear.

Although this is a very rare blue sky and sunshine, none of the people present smiled or were happy about it.

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

Within the range covered by the cyclone, as the upper atmosphere is gradually sucked down to the ground, the temperature of the environment is also dropping sharply, because a layer of frost is rapidly forming on the gray-black ground where the dust has fallen.

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

But everyone watching the big screen knows that this is just the center of the cyclone, similar to the existence of the eye of a typhoon, the faster it forms, the stronger the wind around it.

As far as humans are concerned, we have never observed what happens when the air below minus 100 degrees meets the air at a temperature above zero.

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

"Have the soldiers on the defense line done a good job of protection? This storm may be more violent than we imagined, and we must do a good job of coping with it." Chen Xin looked at the blue sky that he hadn't seen for several years. Water was about to drip from the already dignified "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 worriedly, his face was full of worry: "Humans can't resist this kind of bad weather, but those alien creatures can't be sure!"
