"No, no, no, I don't need it," the meat delivered to the door, but Zhang Xiaoming subconsciously refused, and hurriedly waved his hand.

Duck Keer took his hand and slid into his arms, "Do you think I'm dirty?"

"It's not this, it's not this......"

"As soon as others come up, they press me on the bed to do things, but you still care about me, prove that you are a good person, I know you want it, I will give you ......"

(xxx word omitted here)

After the two took a mandarin duck bath and got dressed, Zhang Xiaoming sent Duck Keer to the door of the hotel, helped her call a car and sent her back, while he stood quietly in the cold wind......

——

There was no major event in the next six months, Yang Pingfan commuted to work normally, dated Li Lan on the weekend, and began to talk about marriage, and the development of Galaxy Technology Company came to a standstill, because of the rhythm of public opinion of Cui Na, the human transgenic experiment could not be carried out at all, and even animal protection organizations came to intervene, saying that the company's use of animals for experiments was inhumane......

On the contrary, the development of X company is booming, and the super battery is being promoted at an unprecedented speed, Liu Yuan is not taking rough marketing measures, but convening all kinds of traditional battery manufacturers in China, willing to provide super battery technology at a low price to help them achieve industrial transformation.

With such a good thing, coupled with the state's subsidies for the battery industry, the major manufacturers accepted the technical support of Company X without the slightest hesitation. Liu Yuan is certainly not a living Lei Feng, this gentle move to avoid the battery industry and downstream cars, notebooks, mobile phones, battery cars, etc., need the turmoil of the battery industry, the line of sight has been smoothly upgraded, so it has been highly praised by the official, the four major banks have provided large interest-free loans to help X company expand its scale.

Cheng Pengyu also began to reap his own fruits, in the city's election this year, he was unexpectedly and successfully selected, originally the deputy mayor in charge of cultural propaganda, but the powerful Liu Yuan used the influence of X company and some small means to make Liu Yuan successfully ascend to the position.

Although Galaxy Technology is struggling in human genetically modified organisms, but the results of cooperation with X Company have made rapid progress, through the way of mutual share exchange with X Company, to achieve resource integration, X Company has received molecular biology and gene cloning technology support from Galaxy Technology, and initially built a biological brain server that simulates the human cerebral cortex, and the first project of trial operation is to carry out weather forecasting.

Li Suifeng listened to Liu Yuan's test plan and was very surprised, "Weather forecast? Doesn't the country already have Fengyun satellites and supercomputers? Why do we still want to do this?"

Liu Yuan explained: "Weather forecasting, something we have become accustomed to, often ignores the technical requirements and complexity behind it, as well as the difficulty of accurate forecasting. ”

The so-called unpredictable weather is unpredictable.

Weather has always been nature's most powerful means of showing its fury and unpredictability.

Since ancient times, human beings have tried to grasp the meteorological laws behind natural phenomena such as wind, clouds, thunder, lightning, rain, snow, and hail, and make accurate predictions of future weather.

As early as 3,000 years ago, in the oracle bone inscriptions, there were records of the weather situation, including wind, clouds, rainbows, rain, snow, frost, xia, tornadoes, thunderstorms, etc., and the "24 solar terms" were the first climate clocks in human history to reflect the annual cycle.

In the West, about 340 B.C., Aristotle wrote the world's earliest meteorological monograph - "General Theory of Meteorology", which not only expounded the causes and distribution of various winds, atmospheric light phenomena such as halos, rainbows, thunder and lightning, the formation of clouds, rain, hail and haze, and climate change throughout the year, but also systematically sorted out various meteorological ideas and experiences, and put forward his own insights and theories on various weather phenomena, making it a systematic science.

In addition to the official and intellectual level, countless sailors, fishermen, farmers, and hunters who relied on the sky for food predicted the weather by looking at the clouds, the wind, the sky, and the objects, and summed up a set of valuable empirical laws in their practical life.

These efforts have yielded some success, however, they are often only superficially described and not very accurate.

Once someone can make a more accurate prediction of the weather, it is often a matter of life and death.

In the forty-eighth chapter of "Romance of the Three Kingdoms", "Banquet on the Yangtze River Cao Cao Fu Poems, Lock the Warship and Northern Military Force", it is written that Zhou Yu led the crowd to see Cao Cao's warship across the river on the top of the mountain: when he was watching, the wind suddenly blew and the waves in the river took action. A gust of wind blew the flag horn on Zhou Yu's face. Yu suddenly remembered something in his heart, screamed, and fell backwards, spitting blood. When the generals first aided, they were already unconscious.

And Zhou Yu has nothing else to worry about, owes Dongfeng Er.

That's why there is the forty-ninth episode of "Seven Star Altar Zhuge Sacrifice Wind Sanjiangkou Zhou Yu Arson".

Therefore, weather forecasting has been the top priority since ancient times, "Looking at the sky tonight, you can know the major events in the world." ”

The earliest method used in modern weather forecasting is the weather map method, which is to fill in the meteorological conditions of different places at the same time on a map, and then infer the future movement path and intensity changes of the high and low pressure systems, and then realize the weather forecast according to the impact of these systems on the climate.

The development of science and technology has caused mankind to abandon such backward and inefficient methods, and instead use supercomputers to model the earth and atmospheric environment, using historical observation data and meteorological satellite observations as the initial parameters of the model, and then using numerical analysis methods to solve them.

Weather forecasting has become a science that seeks the only answer in the vast and rapidly changing big data.

Therefore, modern weather forecasting is essentially a numerical calculation and logical deduction.

The first is modeling.

Modeling refers to the establishment of a physical model of the state of the earth and the atmosphere, usually using a set of partial differential equations to describe the basic laws of the state and motion of the atmosphere, other factors also need to be considered, such as whether the surface is grassland or snow, what the terrain is, etc., because it will affect the heat and air flow.

Once you have the model, you also need the initial parameters. Through meteorological satellites, radars, sondes, ground weather stations and other means, the air pressure, temperature, humidity, wind speed and wind direction at different altitudes are observed.

Finally, the global atmospheric model is established by supercomputing, the model is divided into grids, the observed meteorological parameters are taken as the initial state parameters of the grid, and then the changes of these parameters over time are calculated according to the physical equations.

In general, the prediction accuracy of a model depends on what factors the scientist considers, how large the mesh is, and what time step the solution is required.

The finer the grid, the smaller the scale of the weather forecast, and the smaller the time step, the more recent the future can be forecasted.

However, there is no model that can take all the factors into account, and it is not realistic to draw too thin a mesh or achieve too small a step size, because the computation will proliferate, and sometimes it will not even be solved. Therefore, modeling is essentially a visual embodiment of supercomputing power.

Presumably, you and I can also feel that modern weather forecasting is becoming more and more accurate, and at the same time, the prediction accuracy is also improving, because the calculation speed of supercomputing is constantly rising, but there is always a bottleneck in supercomputing, and there is still a shortage of short-term forecasting in a small area, and there is an obvious problem of insufficient accuracy.

We live in an environment where there is no drastic climate change, and we may not be able to empathize with this requirement of accuracy, but for fishermen who make a living at sea, short-term weather forecasts can be a real lifesaver.

Typhoons, waves, and other weather forecasts may be just a bunch of data for ordinary people, but for fishermen, it is whether they should go to sea today, whether they can make a gain, or even whether they can come back alive.

Every minute in advance, every little bit of precision in the forecast, there are living people behind it, because the sea is never merciful.

In this showdown with "Fengyun Data", faster computing speed and intelligent AI are needed to analyze.

I used the first test item of the biological brain on weather forecasting, which was based on this consideration. The biological brain not only has super computing power, but also has a huge storage space, which allows programmers to write a highly intelligent AI to perform logical operations.

AI can help scientists find clues and basis for predictions and deduce possible changes in the future through deep learning of a large amount of historical meteorological data, thereby providing strong assistance for manual forecasting.

If even such a large amount of data can be handled without obstacles, then it will be easy to deal with other things.

Liu Yuan's words persuaded Li Suifeng, and a weather forecast calculation system based on biological brain was quickly built.

Under the instruction of Cheng Pengyu, the Suzaku Meteorological Department has launched in-depth cooperation with Company X, intending to promote the breakthrough innovation of accurate urban meteorological forecasting and smart city meteorological services.

According to Liu Yuan's vision, the accurate severe weather prediction model developed by AI based on biological brain will be committed to learning from massive historical data to calculate the changes and movements of clouds and the laws of thunderstorms, so as to predict the future weather conditions of Suzaku and warn of disastrous weather.
