I can upgrade the shelter-Chapter 709 - 607 Bomb Cyclone

The arrival of the cold wave is nothing new for humanity. Even now, when the entire world is frozen, there are still multiple occurrences of cold waves each year.

Although each cold wave causes the already low temperatures to drop even further, sometimes approaching minus 100 degrees, for Flame Country, aside from the first time when it was indeed chaotic, they've become accustomed to dealing with cold waves after the first few times.

After all, with someone like Chen Xin who seems to have supernatural help, the Energy Towers serve as high-tech heating devices, mitigating the impact of cold waves for Flame Country.

Especially now, as the snow accumulates thicker and cannot melt due to the cold weather, they even isolate the colder external temperatures to some extent.

It's somewhat akin to an Inuit snow house; as long as the internal temperature is maintained and heat doesn't escape, for humans, a cold wave is merely short-term severe weather that confines them indoors.

However, this time the cold wave appears somewhat different.

Not only is the cold wave moving south faster than expected, but the previous thunderstorm experiment also created a storm in the Dongting Lake Region.

Thunderstorms are a form of extreme weather, and the Weather Controller creates thunderstorms by locally warming the air, storing energy, then causing positive and negative charges to release through air friction.

According to the original plan by Chen Xin, meteorologists, and physicists, the thunderstorm should naturally dissipate after the experiment ends, without resulting in subsequent adverse effects.

Although the increased local temperature might have some impact on the weather, it wouldn't be severe.

However, as the cold wave suddenly accelerated southward, reaching the Dongting Lake Region within hours, everything changed.

It is widely known that when cold air meets warm air, alternating temperatures can lead to various weather phenomena.

One such phenomenon is when pressure rapidly drops in a short time, leading to violent weather changes.

This phenomenon is known as a bomb cyclone, typically seen in North America, caused by warm moist air meeting cold air, resulting in rapid pressure drops and extreme weather events.

Scenes like this also appeared in the famous disaster movie "The Day After Tomorrow."

A huge cavity forms in the clouds, akin to a typhoon eye, with cold air from the upper atmosphere sucked to the ground due to rapid pressure drops, instantly freezing everything.

Now, as the cold wave moves south and meets the warm air mass created by thunderstorms over the East Dongting Lake Region, an immensely fierce bomb cyclone is forming.

Even the most experienced meteorologists can't predict the terrifying destruction this low-pressure system might wreak, as humanity has never witnessed what happens when sub-minus-100-degree cold air meets warm air of several degrees.

Since the birth of humanity and the formation of civilization, with written records, the atmospheric circulation system on Blue Planet has been relatively stable.

Though there have been occasional severe weather events, excessively extreme weather phenomena have never occurred.

But this time, humanity will witness perhaps the most terrifying weather phenomenon ever recorded.

Because daylight has come.

"With this low-pressure system forming, a large amount of upper-level air is being drawn down to the ground. This gradually forming pressure system is now like a gigantic vacuum cleaner, sweeping away air from above, along with dust and particles in the air," the meteorologist explained to those around him as he pointed at the screen showing captured footage, "And because these dust and particles are being sucked to the ground, the sun, which was previously blocked, can naturally shine on the ground."

"The thunderstorm experiment artificially created a warm air mass in the air. As the experiment stopped, the warm air mass lost its energy supply; combined with the cold air from the southbound cold wave, the temperature began to rapidly drop, causing airflow to move from top to bottom, forming this low-pressure system. Am I correct?" After listening to the physicist's explanation, Chen Xin asked about the cause of the low-pressure system's formation.

The meteorologist nodded, but did not forget to add, "The principle is indeed like this, but this time the low-pressure system formed too quickly, and the temperature drop was too drastic, resulting in this terrifying phenomenon."

With a solemn look, he glanced at the brightening cavity on the screen.

Footage of the eye of the storm created by this low-pressure system showed a thick layer of dust on the ground. In the long-lost sunlight, it turned into a grey-black scene, while the sky gradually transformed from dim yellow to clear blue.

Despite this rare blue sky and sunshine, no one present wore a smile or felt any joy.

For all this happened within just half an hour, and with the formation of this cyclone, the visible coldness was descending.

Within the cyclone's range, as the upper-level atmosphere gradually fell to the ground, the environmental temperature is also plummeting rapidly, as frost quickly forms on the dusty grey-black ground.

Though the footage on the screen depicted a calm scene where even a leaf might not be blown away,

everyone watching the screen knew this was merely the storm's center, akin to a typhoon eye; its rapid formation meant stronger winds on the periphery.

For humanity, we've never observed what happens when air at minus 100 degrees meets air of above-zero temperatures.

However, according to current meteorological data, the quicker the temperature drop, the faster the cyclone forms, the fiercer the storm This low-pressure system brings becomes. Evidently, an unprecedented storm is gradually taking shape.

"Have the soldiers on the front line completed their protective measures? This storm might be more intense than we imagined, and we must be prepared," Chen Xin asked the general with a face as heavy as water, gazing at the blue sky unseen for several years.

The general responded seriously, "Frontline soldiers have received orders, everyone is on high alert, prepared for extreme weather and various sudden situations, I trust our soldiers can handle this weather."

"That's good, but remind the soldiers to be cautious of potential large-scale attacks from alien creatures," Chen Xin reminded uneasily, his face full of concern, "Humans can't withstand such harsh weather, but the aliens might not have the same issue!"
