Li Zhongxin and Mr. Tian and others simply explained the results of the meteorological expert group. After obtaining some answers he wanted to know, they did not talk about business affairs and started talking about it from all over the world.

Although the people in these meteorological expert groups are very old, they are in good spirits. After drinking the red wine brought by Moutai and Li Zhongxin for a while, everyone has a lot of topics to talk about.

Li Zhongxin's age is very different from them, and these old experts and Li Zhongxin do not have much common language. As they talk, some people started chatting on their own.

During this time, Li Zhongxin just listened humbly to Mr. Tian and Mr. Zhao, but he didn't interrupt. After all, they talked about professionalism as they talked.

The things they talked about are all about meteorological matters, such as meteorological equipment, and some of the meteorological things.

When Tian Qingyu talked about the meteorological equipment produced by some precision instrument factories in China, there was some gap with foreign equipment. When he wanted to import some meteorological equipment from abroad, Mr. Zhao, who was beside Mr. Tian, ​​was not happy.

"Laotian, I also know that since our country has used some foreign meteorological equipment, the forecast is much more accurate than before. However, I still say the same thing: When we didn't use those precision equipment before, there was no mistake in the forecast weather in my forecast.

Each of the equipment abroad is very expensive and can be said to be a sky-high price. Our country's foundation is still weak, so we cannot spend all our money on it.

We should support our domestic products, and we can help those factories conduct research and development." Mr. Zhao said to Mr. Tian with a dark face.

At this time, Mr. Zhao felt that Mr. Tian said that he would also import advanced meteorological equipment from abroad, which is not the case. They should support domestic things, and they are old guys who can help those factories improve these things. Once domestic meteorological equipment is produced, it will save the country countless foreign exchange.

"When did our meteorological research start? I have never bought it clearly. In ancient times, we didn't have the equipment we are now, so how did we predict and judge the weather? Did you say that we didn't use equipment based on the results summarized by people in ancient times?" Li Zhongxin asked Mr. Zhao, who was next to Mr. Tian very respectfully.

Li Zhongxin still had a little doubt about what Mr. Zhao said during his chat that even if he didn't use some advanced imported equipment, he could judge some weather, and his accuracy rate would not even be much worse than those equipment.

You should know that even if you have advanced equipment, the weather forecast is not 100% accurate, because this thing has a fault tolerance rate and the concept of error is very large.

There are many times when it is said that it is going to rain in this place, but suddenly a gust of wind comes. The wind is a little heavier, and it blows away the rainy clouds and stops raining.

So! Li Zhongxin still doesn't believe what Mr. Zhao said.

Another point is that Li Zhongxin also resolved the embarrassment of Mr. Tian. Mr. Tian just said that he wanted to buy some advanced foreign meteorological equipment. This matter! In fact, it was for him to listen to Li Zhongxin. After all, some foreign high-end meteorological equipment, even if Mr. Tian and others hold foreign exchange, they may not be able to buy them.

You should know that the reason why Jiujingqian was able to buy so many high-tech meteorological equipment is because Zhongxin Company has stocks of those high-tech companies and has certain cooperation with the major shareholders of those companies. Moreover, meteorological equipment is generally unaffordable for the country. Therefore, several aspects are superimposed together, Jiujingqian can buy advanced meteorological equipment.

Mr. Tian also hoped that Li Zhongxin would support some equipment from their meteorological expert group, but! Mr. Zhao did not understand such a thing, or that the meteorological expert group did not say that those high-end meteorological equipment were sponsored by Zhongxin Company.

This matter! Li Zhongxin can understand it too much. One aspect is that both Mr. Tian and the Meteorological Bureau need to maintain a sense of mystery. Moreover, the source of these things will not be expressed without being expressed. When will the domestic meteorological equipment be studied, this thing will not be deliberately kept confidential.

So, Li Zhongxin directly changed the topic.

Mr. Zhao, with a rosy complexion, looked at Li Zhongxin. He smiled and said, "This matter is not something I am talking nonsense. Many times, we just need to find the right key points, which are even much more accurate than what the machine calculates.

As for our country's research on meteorology, it must start with the slave society. Our country has emerged in many talented people, and our ancestors have developed various advanced methods to measure and map the weather a long time ago.

As early as the Xia, Shang and Zhou dynasties, we Chinese realized the importance of wind. From the Book of Songs, "Chu Ci" to "Huainanzi", we are full of records of wind.

Ancient people realized very early that the change of wind means that the weather will undergo major changes. If you master the operating rules of wind, you will also master the secrets of the weather.

During the Spring and Autumn Period, the Chinese proposed weather theories related to wind. With the divisions of "floating wind", "declined wind" and "burning wheel wind", Sima Qian's "Records of the Grand Historian" it was clear and summarized systematically, and various wind conditions and possible weather conditions were summarized. What kind of weather conditions will be there every year can be judged by the wind!

Related wind-looking instruments are constantly improving. The most famous one is the "Elevening Wind Copper Bird" invented by Zhang Heng, a scientist in the Eastern Han Dynasty. Even if the wind direction is thousands of miles away, it can make judgments based on the rotation of the bird's head to use it as a reference for surveying and mapping the weather.

The archaeological community has been controversial about whether this copper bird exists before. It was not until 1971 that relevant archaeological results were unearthed from the Eastern Han Dynasty tomb in Anping County, Hebei Province, and finally responded to such doubts!

This is about wind measurement and rain measurement! For annual climate change, measuring rainfall is an important task, but in ancient conditions, how to measure rainfall in precipitation once?

There were long been special rainfall meters in ancient China, and Qin Jiushao, a mathematician of the Southern Song Dynasty, proposed the traditional rainfall test conversion formula.
