"Level 8."

Deng Wen was secretly shocked when he heard this number. Since the second snowfall, the wind has been increasing.

From the beginning, level 3 has gradually risen, especially in the past two days, it has soared directly from level 6 to level 8.

The wind is getting stronger and stronger.

Generally speaking, the definition of wind power level is roughly like this:

.........

Level 3: Breeze, leaves and small branches shaking, and flags unfold.

Level 4: The wind can blow dust and paper on the ground, and the small trees shake.

Level 5: Breeze, waves in the river.

Level 6: Strong wind, big trees shaking, wires whirring, and it is difficult to hold an umbrella.

Level 7: Rapid wind, difficult steps.

Level 8: Strong wind, broken branches, inconvenient walking in the wind.

Level 9: In strong wind, the top of the chimney will be blown by the wind, and objects on the ground will be blown away everywhere.

Level 10: Strong wind, trees are blown down, and ordinary buildings are destroyed.

Level 11: Storm, rare on land, has destructive power. Level 12: hurricane, has great destructive power. Level 13: typhoon or hurricane, has great destructive power. Level 14: Strong typhoon or hurricane, has great destructive power.

.........

In two days, the wind power rose from level 6 to level 8.

It may rise again in the future.

Xiao Gao shouted to Deng Wen: "Professor Deng, should we report this situation? The wind is increasing too fast."

Deng Wen put away his telescope and nodded:

"Okay, let's go down."

Although the wind at level 8 is already very strong now, it is not surprising to survivors living in the end of the world.

The buildings in the Dazhang Tree Base are extremely solid.

Even those greenhouses can withstand typhoons of more than ten levels.

This is not only the sturdy greenhouse, but also related to the tall walls of the big camphor tree base.

These fences that are dozens of meters high blocked the typhoons blowing outside.

Due to air pressure, most of the winds blowing from the sky are broken and dispersed winds, and the wind is not that strong.

But if there were no walls to block a typhoon of more than ten levels and the greenhouse alone would have been blown away by the wind.

The two crawled along the straight ladder and climbed down little by little.

At a height of hundreds of meters, they climbed up the straight ladder. It looked very dangerous, but in fact it was not safe at all.

However, at least they were not crawling outside, but climbing down the space in the center of the steel frame and concrete building.

The wind was blowing, and the two of them were blowing their clothes rustled by the wind.

They were wearing the New Year gift bags and gloves they had distributed, touching the cold iron poles again and again.

Finally, five minutes later.

They climbed to the inner city wall that was more than 70 meters high.

The two walked to the chalet and pressed the first floor of the elevator.

There are still several people patrolling the inner city walls.

"Professor Deng, do you think it will turn into a typhoon later?" Xiao Gao asked with some concern.

Generally speaking, the formation of typhoons is extremely rare.

The formation of a typhoon is an extremely complex meteorological process that involves multiple factors.

Basic conditions include warm sea temperature, humid air and proper wind shear.

There is basically no typhoon inland.

but......

In this end of the world, we cannot use common sense to view it.

There was a super hurricane disaster before, and the wind intensity was simply outrageous.

Deng Wen had seen a zombie fly into the sky during his lifetime. At that time, he had not joined the Dazhangshu Base. It was located in the North China Plain, in the plain area. Since there were no tall mountains to block the hurricane, the place where the hurricane passed was like artillery fire.

A house was blown up in front of a hurricane.

He was hiding in a basement in the city at that time and survived.

But at the Dazhangshu Base, the hurricane wind power is reduced because it is all mountains and hills.

Ganzhou Province has been a relatively isolated area since ancient times, which is caused by the terrain.

There are tall Wuyi Mountains in the east, which isolates typhoons in the east.

There are Jiulian Mountains in the south, Luoxiao Mountains and Wugong Mountains in the west,

There are Jiuling Mountain and Jiuhua Mountain in the north, and Huangshan in the northeast.

This chapter is not over, please click on the next page to continue reading! Closed, which also leads to a relatively poor economy before the end of the world.

But at the same time, there are few natural disasters in this place.

However, the natural disasters in the end of the world are too powerful. Even after the hurricane drops, the wind power at the Dazhangshu Base is extremely terrifying.

They hurried back to the Natural Disaster Research Institute.

"Where is Dean Song?" Deng Wen caught a colleague and asked after he came.

"What's wrong with it in the office? I see the wind has become stronger today. Have you noticed anything?" asked the colleague.

Deng Wen left without looking back when he heard that Song Zhihong was in the office.

I left a sentence: "Let me tell you later."

He ran, while taking off the hat on his head.

Because his hair was squeezed by the hat for a long time, his hair was so ugly that it looked like a chicken coop.

He led Xiao Gao all the way to Song Zhihong's office.

Without knocking on the door, he pushed the door and broke in.

In the office, Song Zhihong was touching his chin and staring at the terrain model in front of him to think.

Bang!

The door was suddenly pushed open, which scared him.

"Why don't you knock on the door when you come in? I'm scared to death." Song Zhihong patted his chest and said with lingering fear.

His heart just now had half a beat leaking, damn it.

Deng Wen said in a trembling voice as soon as he came in:

"Director Song, the wind has reached level 8 now!"

"Level 8??!"

Song Zhihong widened his eyes and asked in surprise:

"So quickly, it's still level 7 this morning!"

He quickly ran to the window and opened it.

Wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow wow w

The snowflakes outside blew in instantly.

He frowned and observed the wind outside for a while.

Quickly close the window.

Turning around, picking up a brush and writing on the wall about the recent increase in wind.

Obviously, the wind is increasing faster and faster.

"It's not good to go on like this, it's too fast." Song Zhihong murmured.
