The short-term data are highly consistent, which basically shows that there is not much problem with the short-term weather forecast on both sides.

But in the long run, a small gap can have a very big impact.

This is like 1.01 and 0.99, the difference between these two numbers seems to be very small.

After many exponential operations, the results will be very different.

After seeing the data submitted by Suanjing and Vulture, netizens from various countries began to discuss it on major social platforms.

"Both the alchemy and the vultures predict that it will be sunny here tomorrow. It seems that we can go out and play with confidence tomorrow."

"The maximum temperature forecast differs by one degree Celsius, so it shouldn't be a big difference."

"It looks like the weather forecast is much more professional than usual. I wonder if they can keep disclosing these data to the public in the future, so they don't have to look at the weather forecast."

According to the standards set by both parties, the weather forecast data that needs to be submitted includes daily temperature range, weather conditions (sunny, rainy and snowy, cloudy, cloudy, etc.), wind direction and wind force, etc.

More specifically, it is also necessary to provide the temperature at each moment, when it rains, the amount of rainfall, etc.

What attracts everyone's attention is...

There are very big differences in the 24-hour weather forecasts of certain locations between the Suanjing and the Vultures.

And one of those locations is Leatherway Nie.

Reeseweine is a small country in Europe. If it weren't for the leader of this country who likes to show off, many people would not know about this tiny country.

In the weather forecast for Lethweinie tomorrow, the vultures gave an entirely clear sky.

However, the calculations are completely contrary. It is predicted that there will be a heavy rainstorm in Reeseweni, and it is even more likely that some floods will occur.

It is very unusual for two quantum computers to produce completely opposite predictions about the weather within 24 hours.

You must know that among the 5% difference in predictions between the two quantum computers within 24 hours, most of the differences are very small differences.

For example, the temperature forecast differs by 1 degree Celsius, the wind speed differs by one level, etc.

There are very few forecasts with completely opposite weather conditions.

Because the area of ​​Leatherweinie itself is very small, less than one of our provinces, almost all the cities in their territory have similar weather conditions.

After learning the news, the people of Leatherweinie were the first to stand up.

"I heard that the Chinese arithmetic predicts that we will have a heavy rainstorm today? What a joke! We still have clear skies here, and there is no sign of a heavy rainstorm at all."

"Are they using a weather prediction system made with their feet? Even I can tell with my eyes that today is definitely a sunny day. The weather forecast in the United States is more accurate. This is our partner."

"Haha, we have been experiencing drought here for a long time this year, and we are looking forward to a rain. If there is such a heavy rain, I will live on Twitter and wash my hair upside down. If it doesn't rain, I will give the Sutra

Smashed."

Most of the people in Leatherweinie regard the predictions made by Suan Jing as a joke.

This is not only because the weather here is indeed cloudless, and it doesn't look like it's going to rain at all.

At the same time, it is also because they maintain a high degree of consistency with the United States in all aspects.

From the bottom of their hearts, they definitely believe in the weather forecast in the United States.

After checking the weather forecast data published by Vulture, Xu You also discovered the difference in their weather forecasts for Reesewe Nie.

"Sure enough, with the vulture's computing power, it still hasn't been calculated to this level." Xu Youxin said.

The heavy rain that is about to appear in Reesewenie is an unconventional heavy rain.

According to normal weather prediction models, it is difficult to predict a heavy rainstorm within an hour before it starts.

Because but from a certain perspective, these data do not have the conditions to produce heavy rainstorms.

But taken together, after deep and complex calculations, a conclusion can be drawn.

This heavy rainstorm is bound to happen.

…

IBM, Vulture Quantum Computer Project Team.

"Is there really going to be a heavy rainstorm in Reesewe Nie in the next 24 hours?"

"We have communicated with Google researchers, and the possibility of this is almost zero. Their weather prediction model is very accurate, and the accuracy of weather prediction within 24 hours reaches more than 99%. Even if the prediction

If there is a deviation, it cannot be such a serious deviation."

"But why do their quantum computers have completely different predictions from ours?"

Even if IBM had more confidence in its vultures, it would not believe that such a serious error would occur.

"This...maybe there is a bug in their program. Even the local people in Leatherweinie don't believe that there will be heavy rains there today."

"That's right. Then wait until tomorrow and we will know whether it will rain there."

Somehow, people in the IBM Vulture project team still felt that something was wrong.

From the performance of the previous generation of islands, we can see China's leap in technological strength.

In any case, their next-generation quantum computers are not likely to have bugs so easily.

At eight o'clock in the morning, Xu You and the entire economic calculation project team held a meeting to discuss weather forecasting.

"Judging from the current situation, the score of the sutra calculation is slightly ahead of the vulture. The performance of the sutra calculation is very stable, and the vulture did not make any mistakes. The most critical part today is to look at the weather results in the Reesewe Nie area

Already."

According to Suanjing's weather forecast, the heavy rain will begin around 12 noon today in Jijing time.

There are still four hours until the heavy rain comes.

Immediately afterwards, Xu You began to analyze the reasons for the prediction of today's weather in Lesewe Nie.

"In the weather prediction model of Suanjing, rainfall is mainly caused by the following conditions."

"The first one is the water vapor conditions. Water vapor is the source of rainfall. When there was a heavy rainstorm in Reeseweine four hours later, the water vapor came from the ocean to its west."

Xu You displayed a series of model formulas and corresponding weather maps on the big screen, simulating weather changes in the next few hours.

"The second condition is the dynamic condition. Abundant water vapor supply is equivalent to providing sufficient raw materials, but it is not enough to form rainfall. In addition, a sustained and strong upward movement is required. From here

Up to this point, the entire range is a large-value area of ​​vertical velocity. This range also happens to coincide with the territory of Reesewe Nie."
