This flood is a once-in-a-millennium disaster and has had a huge impact.
Wu Siyuan saw in the future that this flood affected a total of 14.814 million people in 1,664 towns and towns in 150 counties (cities, districts), and resulted in a total of 398 deaths and missing persons.
In terms of agriculture, 14.7 million acres of crops were affected, of which 9.7 million acres were affected by disasters and 5.7 million acres had no harvest; 120,000 acres of shed facilities were damaged, 10.6 million acres of farmland were affected, 18,527 affected breeding farms were affected, and 11.14 million livestock and poultry died.
Head (only), 6.39 million square meters of pens were damaged, 330,000 acres of fishery were affected, and 94,000 acres were affected. It can be said that this is the most serious agricultural disaster in many years.
Not to mention other losses, direct economic losses reached 114.2 billion yuan, not to mention indirect losses.
The main area affected by this disaster is the Shangdu area.
Starting at 8 pm on July 19, heavy rain poured down in the Shangdu area, and the water on the ground poured out like a gate opening.
As of 8 p.m. on July 20, for 24 hours, it rained non-stop. The cumulative rainfall was as high as 552.5 millimeters, which means the rain reached 55.25 centimeters. The average rainwater on the ground rose by as much as half a meter.
In fact, to be precise, this heavy rain started at 8 pm on July 17, and as of 8 pm on July 20, the cumulative precipitation reached 617.1 mm, while the annual average precipitation in Shangdu was only 640.8 mm.
In other words, the rainfall in Shangdu in three days is almost the same as the annual average rainfall in Shangdu.
According to monitoring by the local meteorological department, Shangdu received 201.9 millimeters of rainfall in one hour.
What kind of digital concept is this?
This is equivalent to 103 volumes of West Lake water poured from the sky into the Shangdu area.
The drainage system in Shangdu is useless in this regard, and it is impossible not to cause flooding.

After Wu Siyuan saw this incident in the future, he has been worried about it and wanted to do something.
It's not just a matter of influence.
One of the most important reasons why the disaster was so serious this time was the typhoon [Fireworks].
Severe Typhoon Fireworks is the sixth named storm in the 2021 Pacific typhoon season. It was upgraded to a tropical storm by the Central Meteorological Observatory at 2:00 on July 18, 2021, and was upgraded to a severe typhoon by the Central Meteorological Observatory at 11:00 on July 21.
It’s only June, and there’s not even a single horoscope yet!
Typhoon [Fireworks] is the “culprit” that bears the brunt of this heavy rain.
Although the [fireworks] are still far away, when it rains heavily, they are still 1,000 kilometers away in China, which can be said to be thousands of miles away.
But its influence is very strong, and the subtropical high pressure is now emerging. The combined effect of the two causes a large amount of water vapor on the sea level to ride on this easterly wind, and eventually it rains heavily.
The terrain is also the [accomplice] that caused this disaster to be so severe!
Judging from the subway map, there are Taihang Mountains in the north, and mountains composed of Xiong'er Mountain and Funiu Mountain in the west. After these mountains are formed, they form a natural wall.
The function is equivalent to the windward slopes of mountains. When typhoons carry water vapor from the sea and want to transport it, the mountains formed by these mountains act like a natural barrier, blocking the way.
Coupled with the convergent uplift that occurred in the mountain front and the flat terrain in some areas, the rain in this part eventually formed a concentrated rainfall situation in these flat areas.
This resulted in a heavy rainstorm!
Wu Siyuan may not be able to stop the impact of typhoons on heavy rains, but he wants to reduce the damage caused by heavy rains to the whole country as much as possible.

The first [Dasheng Mobile Phone] to be released soon is related to the future strategic development direction of [Chaoqun Group], and will undoubtedly bring immeasurable influence and energy to Wu Siyuan.
But at this time, Wu Siyuan's heart was no longer on it.
He came to [Gushen Group], which was independent from [Chaoqun Group] and was responsible for agricultural-related businesses!
[Gushen Group] has a department that makes weather forecasts and serves agriculture.
Although modern technology has developed rapidly, agriculture still relies on nature.
If the weather is bad, if it rains for a month, or if there is a drought for several months, the crops will definitely be destroyed if people don't die.
This business mainly informs agriculture, water conservancy, meteorology and other fields, and provides data planting for agricultural planting through automatic monitoring and big data analysis. In fact, it provides forecasts of future weather, and it is also accurate forecasts.
Two aspects are the most critical.
One is astronomical data.
The other is data processing.
Astronomical data mainly comes from meteorological departments of various countries. Of course, more powerful commercial companies will obtain more meteorological data by launching meteorological satellites and establishing meteorological observation stations.
[Cershen Group] is backed by [Chaoqun Group], and the astronomical data it can obtain are among the best in the world.
As for data processing, it essentially uses algorithms to analyze and make statistics on celestial phenomena, and then derive the celestial phenomena in the future.
This is also part of the [Smart Agriculture] that [Cershen Group] has been promoting.
Originally, this business had been tepid, and its performance was not bad, but not impressive enough.
After all, weather forecast seems simple, but it is actually very complicated.
There is a saying in weather forecasting called "chaotic system", which means that small changes in initial conditions will lead to long-term huge chain reactions in the entire system.
Of course, not all changes in the initial conditions of the system will lead to huge chain reactions.
Only this kind of system that can produce this kind of influence is called a [chaotic system].
Chaotic systems are not really random, but appear to be random. The randomness they present comes from the fact that there are too many factors that affect the movement in the system, so that it is impossible to understand all the data and make accurate predictions.
Weather is such a [chaotic system]. We can obtain more accurate meteorological data through more advanced meteorological satellites, but more accurate does not mean absolutely accurate. Small differences will lead to large differences in the final weather conditions.
.
Therefore, the weather forecast may be inaccurate from time to time.
Sometimes you see the weather forecast on your phone saying it will rain in two hours, but in fact, the sun shines two hours later.
