I really just want to be a scholar

Chapter 644 All science must be rigorous!

Although there were some surprises and fear of this frighteningly famous star mathematician, Wan Baoshan and Mao Hongen quickly calmed down.

The phenomenon of "dry rain" belongs to the category of meteorology. At most, it has something to do with physics, but not much to do with mathematics. Even if your mathematics level is astonishingly high, Qin Ke can't beat dozens of people in such a professional field. Veterans with years of experience.

So Wan Baoshan nodded gracefully and said, "This is Professor Qin Ke, right? If Professor Qin has any questions, please let us know, and we will help you."

Qin Ke didn't ask questions right away, but said to Teacher Jiang Weixian next to him: "Mr. Jiang, my question will involve our conclusions, is it okay?"

As he spoke, he picked up a pen and wrote two words in his notebook - "rain steaming wind" and "fire rain".

When Jiang Wei first saw these two words, his eyes showed surprise, and then he nodded happily: "Okay."

Only then did Qin Ke look up: "Professor Wan, please switch the PPT back to page No.19."

Wan Baoshan still switched to the PPT. This is the meteorological data analysis page when the "dry rain" phenomenon occurred. Is there any problem? I think the data curve drawn on this page is fine. I believe that a great mathematician like you can't understand such a simple data graph?"

Qin Ke smiled lightly, and signaled to the staff of the weather station here to share his laptop screen, and then opened the original temperature and humidity data when the "dry rain" phenomenon occurred twice.

Qin Ke circled several lines of data with the mouse, and asked: "Professor Wan, did you ignore these lines of data in the data analysis on page No.19? It is the highest temperature and the lowest humidity value, and a comparison of these values ​​between the two 'dry rain' events."

After seeing clearly, Wan Baoshan immediately calmed down.

He couldn't help chuckling and said: "Professor Qin, you really know how to joke, don't say that we write such reports, even if we write papers, the highest and lowest values ​​that deviate from the standard values ​​​​are removed and not considered. A few lines of data are obviously out-of-limit data collected by monitoring equipment, and are of no value for discussion. I believe that a great mathematician like you who is used to writing papers is not even clear about such superficial rules, right?"

After talking about it, most of his fear of Qin Ke disappeared. Although his tone remained polite, his eyes showed, "You dare to question me with your nitpicking climatology and meteorology level." teasing.

Even Mao Hongen next to him snorted softly, thinking that Wan Baoshan and I can't beat you when it comes to mathematics, but when it comes to climatology and meteorology, you don't even have the qualifications to be our graduate student!

The attitudes of the two professors are different. The team members brought by them are more surprised, thinking that Professor Qin Ke should not ask such unstandard words?
In the audience, only Jiang Weixian showed unconcealable admiration in his eyes, while Ning Qingyun fell into deep thought looking at these lines of data, and then his eyes lit up, and he quickly searched for the information.

Qin Ke turned a blind eye to the weird atmosphere around him. He remained calm and continued: "From the perspective of conventional meteorological analysis, there is nothing wrong with Professor Wan's approach, but this time we are studying extremely abnormal weather phenomena. Moreover, it is a rare and extreme abnormal weather that has never appeared in the Taklamakan Desert. Every piece of data should not be ignored. I believe that with the accuracy that current weather monitoring equipment can achieve, there is no so-called over-limit data, or the so-called The 'miscellaneous numbers', in my opinion, exist even if they are reasonable, and must have their meaning."

Listening to Qin Ke's words, the surroundings gradually quieted down, and more and more people fell into deep thought.

"And... I have a basis for saying this. These lines of data ignored by Professor Wan and Professor Mao have a significant relationship with the omens represented by these two extremely abnormal weather phenomena." Qin Ke moved the mouse and moved the cursor to Switch to colored pen mode and circle some key data again.

"Please compare the numerical changes of the "meaningless data" mentioned by Professor Wan in the two times when the phenomenon of "dry rain" occurred. Have you found a very important key information? The highest temperature value for the first time is 155 degrees Celsius, and the highest temperature in the second time has reached 230 degrees Celsius. The humidity is just the opposite. The lowest relative humidity recorded in the first record was 28%, and it became 21% in the second time; The value of the difference also shows that when the 'dry rain' phenomenon occurred for the second time, the air pressure difference increased by 50%! The maximum wind speed also increased by 27%!"

Wan Baoshan and Mao Hongen looked a little unnatural, Wan Baoshan opened his mouth and was about to speak, Qin Ke interrupted directly: "Maybe Professor Wan still wants to be tough and insist that these are 'meaningless data', okay, Next we look at these 'dry rain' data that have occurred in the Sahara Desert."

Qin Ke directly asked Shimmer to open a chart that had been sorted out with his lips, and then circled the data of a certain area.

"In the past hundred years, there have been seven recorded 'dry rain' phenomena in the Sahara Desert, of which the numerical change trend of two times is similar to our two 'dry rain' phenomena, and the maximum temperature has also greatly increased. , the lowest relative humidity has become even lower, and at the same time, the air pressure difference has shown a tendency to expand, and the wind speed has also increased significantly!"

Qin Ke looked up, staring at Wan Baoshan and Professor Mao Hongen at the other end of the video, and said word by word: "Three days after the two special 'dry rains', the largest 'rain steaming wind' sandstorm in history appeared in the Sahara Desert , directly turned several cities around the desert into 'sand cities'. This is not the most terrifying thing. The most terrifying thing is that the ensuing 'fire rain', the 'sand-water mixture' of nearly 2000 degrees Celsius The circulation drifted more than 200 kilometers away before falling, and directly burned hundreds of kilometers of forests and cities into white ground!"

Everyone present paled.

As professionals in climate and meteorology, they are naturally no strangers to the so-called "rain steaming wind" and "fire rain".

Rain steaming wind refers to the updraft generated by high temperature in a wide range in desert areas, which makes rainwater completely evaporate in mid-air, so it is called "rain steaming wind", which seems to be similar to "dry rain", but the difference is that Wind force and wind speed.

The dry and strong airflow rises rapidly, which not only brings the sand and dust on the surface of the desert to high altitudes, but also causes a large-scale negative pressure difference, which makes a vacuum near the ground, which will intensify the air circulation, enough to produce an effect similar to a tornado. The strong wind formed a huge sandstorm that swept everything!
Such a large-scale sandstorm is undoubtedly disastrous. Millions of sand grains measured in tons are lifted high into the sky by strong winds, which can cover the sky as dark as night. Once they encounter cities around the desert, they can easily destroy the city Buried into a "sand city"!
"Fire rain" is even more frightening, because there is sand and dust in the air, which makes the evaporated high-temperature water vapor have the conditions to freeze. Once encountering large-scale convective weather, it can turn into "raindrops" and fall.

But even if it falls from a high altitude, these "sand-water mixtures" condensed by high-temperature water vapor still maintain a terrifying high temperature of more than 2000 degrees Celsius. When they fall into forests and cities that are already dry in summer, it is almost inevitable to cause fires. .

If the two extreme abnormal weather phenomena "dry rain" that occurred in the Taklimakan Desert really foreshadowed the possibility of "rain steaming wind" or even "fire rain" in the future, the consequences would be unimaginable!
Wan Baoshan and Mao Hongen's foreheads were also full of cold sweat. If the weather station reported the report according to their original conclusions, it would lead to the negligence of the superior meteorological department. The incalculable loss of personnel and property, they are the biggest sinners!Not only will his future be ruined, but he will also be charged with dereliction of duty!
Wan Baoshan's face turned pale and he was speechless. Mao Hongen took a deep breath to force himself to calm down, and asked, "Professor Qin, this is just your guess. Could it be that such a rare occurrence in the world can only be judged based on a little data similarity?" extreme weather disasters?"

"Of course it's not just the data!"

Qin Ke opened several data files and a painting software: "Every gas flow is inseparable from fluid mechanics. When it comes to the study of climate and meteorology, I may not be very in-depth, but when it comes to fluid mechanics, I learned from Teacher Jiang. , and the level is barely passable.”

He said, directly holding the mouse as a pen: "I also inquired about the atmospheric circulation data of the Taklamakan Desert in the past six months, as well as the surrounding air pressure changes, circulation direction, etc., and then combined the NS equation of fluid mechanics, the Euler method and the Lagrang Japanese method, a simple deduction was carried out through mathematical modeling."

Lines of complex mathematical formulas using NS equations for calculations are unfolded on the painting software.

"Look, by analyzing and deriving the momentum equation, the pressure Poisson equation can be obtained. I used the staggered grid projection method here, discretized the NS equation, and obtained the discretized pressure Poisson equation, and then passed the SOR Technology to solve..."

At the beginning, everyone could barely understand it. After 1 minute, except for Jiang Weixian and a very few professionals who are also very good at mathematics, the rest of the people were already stunned, as if they were reading a book from heaven.

In the end, even Jiang Weixian rubbed his forehead with a wry smile, and only Ning Qingyun was left looking at the big screen with clear eyes, comparing the information in his hand, and keeping up with Qin Ke's rhythm.

"Up to this last step, I have come up with a very rough probability, 5%. This is the possibility of 'rain, steam and wind', and the probability of 'fire rain' is about 0.1%. Of course, because time is limited, The data in my hand is not rich enough, and the established mathematical model is relatively rough, and the probabilities obtained are not accurate, but one conclusion can be drawn that the occurrence of these two "dry rain" phenomena indicates that it will happen in the near future The possibility of the two extreme natural disasters of 'rain steaming wind' and 'fire rain' will never be zero!"

Qin Ke let go of the mouse and stared at Wan Baoshan and Mao Hongen: "This is the question I raised. I wonder how the two professors plan to teach you?"

Advise a P!
I can't even read what you wrote!
Just when Wan Baoshan and Mao Hongen's faces turned from white to red, Qin Ke showed a calm smile:
"Of course, if the two professors still insist that your original conclusion is correct, that is, 'these two dry rains are occasional phenomena under specific conditions, it only indicates that this year there will be a larger temperature difference between day and night and a larger temperature difference in the hinterland of the desert than in previous years. Severe drought and little rain, that’s all.” Please provide more sufficient theory and data to support and effectively refute my deduction. After all, all science must be rigorous, such as mathematics, physics, and meteorology. That's right, right?"

The faces of the two professors finally turned pale, and their conclusions were just a hasty analysis of data plus decades of experience, unlike Qin Ke, a perverted guy who not only dealt with The "dry rain" data at home and abroad have been carefully analyzed, and mathematical methods combined with NS equations have been used to draw impeccable and rigorous conclusions?
They wanted to argue, but when they opened their mouths, they couldn't utter a single word.

In the silence, the applause quickly broke out, and it became more and more enthusiastic. Jiang Weixian's team in the meeting room here, as well as Xia Yongguan, the director of the weather station, and other staff were all shocked by Qin Ke's momentum and performance. I couldn't help applauding, and even the researchers in Wan Baoshan and Mao Hongen's team quietly followed suit.

Especially Deng Zhaoliang, Ding Yuefeng, Xu Jiaxing and others almost smashed their palms.

Wonderful, so wonderful!
What's more important is to be proud and feel refreshed!

How aggrieved and suppressed by Wan Baoshan and Professor Mao Hongen before, how refreshing it is now!
Deng Zhaoliang quietly said to Xu Jiaxing who was seated next to him: "As expected of the so-called 'God of Qin', it's amazing. I haven't seen such a powerful and refreshing counterattack for a long time!"

Xu Jiaxing also nodded excitedly.

Both they and the team prospered, and all suffered losses. Now that they have completely gained the upper hand, how can they feel complacent or unhappy?

When the applause stopped, Jiang Weixian feigned displeasure and told Qin Ke to sit down, and then said to Wan Baoshan and Mao Hongen on the other side of the video: "Professor Wan, Professor Mao, this kid Qin Ke can't speak, he speaks too straight. I'll turn around Educate him well, I hope the two of you will not be offended."

Qin Ke, who was sitting next to him, almost burst out laughing. Jiang is still old and hot. Teacher Jiang is apologizing on the surface, but in fact he supports his point of view. It was crackling.

Wan Baoshan managed to squeeze out a stiff smile: "Academic exchanges are all about seeking facts from facts. Academician Jiang, you are a wise teacher and a talented student. Professor Qin probably will be able to become a master soon."

This guy actually wanted to sow discord, but Jiang Weixian smiled and said calmly: "Professor Wan, don't praise him first, this kid is proud when he praises him, but as long as he can calm down and study physics hard, he will surpass me sooner or later. Even if I fall into the ground, I can close my eyes with peace of mind."

What he said was sincere and direct, and everyone could hear his high hopes and unreserved cultivation intentions for Qin Ke.

Qin Ke's eye sockets were slightly moist.

Whether it is the Jiang Weixian in front of me, or the old academician Wang Heng, Teacher Shi Cunyuan, Teacher Deng Hongguo, Teacher Lin Haibo, and Teacher Zheng Jianzhou, all the teachers I have met along the way are such teachers with excellent character and knowledge. Thank you so much.

The tripartite meeting ended soon. Wan Baoshan and Mao Hongen finally bowed their heads and said that they would continue to study the data of the two "dry rain" phenomena together. Video connection.
