Rebirth: Fight For Life

   Chapter 591 Cold wave red warning 10 days in advance

  How important is the weather forecast?

  Accurate and reliable weather forecasts not only save lives, but also help economic decisions in aviation, energy and utilities, transportation, and other industries.

   It is no exaggeration to say that nearly one-third of a country's GDP is directly or indirectly affected by weather.

   So Kou Xun hurriedly reported the result of the first comparison operation.

   The result of the operation is accurate.

   Operation time, 17 seconds.

The    project team is very dissatisfied and is optimizing the algorithm.

The goal of    is to stabilize the computation time within 10 seconds at a computational scale of 1 km resolution.

   Kou Xun felt like he was going crazy.

   And the boss of the meteorological department also felt like he was going crazy.

   The madness of joy.

  Without contrast, there is no intuitive feeling.

   This is the first instance of quantum computing applied in a specific field, and the power displayed is so terrifying.

  It is different from the math problem that Gu Song remembered that it took 200 seconds to calculate over 20,000 years. This 100-qubit prototype computer calculates a series of real problems.

   is also a mathematical calculation, with different levels.

   Now this prototype machine has exploded not only in the number of qubits, but also in specific applications.

   In fact, this calculation has achieved such results, and the project can really be delivered.

   The next step is to see how the country arranges experts in various fields to learn quantum computing, and then perform algorithm optimization and calculation program compilation according to their own needs.

   But now that we have started, we have to do a better job of weather forecasting.

  Because of the upcoming cold wave, I could have made more adequate preparations.

   Starting from the end of the month, the cold wave that swept over half of the country this time resulted in a direct economic loss of hundreds of billions of dollars.

During the    period, some people unfortunately died.

   This is a big cold wave with several rain, snow and freezing weather. At that time, no such extreme situation could be predicted earlier.

   And now, it’s different.

  In half a month, the algorithm was optimized again and again, Zhang Qingping was very involved and very excited, and the artificial intelligence program modeled by Lin Yaodong also contributed some points of improvement.

   In this process, not only the comparison and accuracy rate of the past data operation results are extremely high. The daily forecasts for the next day, the third day, the seventh day and the fifteenth day are also compared with the real meteorological observation data of the following day, and the accuracy rate has been greatly improved and guaranteed.

   Kou Xun has finally confirmed that quantum computers are so terrifying!

   On January 20, when the quantum computer calculated the latest data with a resolution of 1 kilometer in 8.73 seconds, Kou Xun looked at the result and his expression changed.

   Guo Yue asked curiously, "What's wrong?"

   Kou Xun didn't answer. After a while, he said, "Wait, I'll go to urge the latest observation data. Wait for the data for a few time periods, and count it a few more times."

  Gu Song knew what he saw and was happy to see his prudence.

   The meteorological observation stations of the meteorological department scattered all over the country, because of the attention received after Kou Xun's report, they have been operating with full force, and the frequency has increased to collect the latest meteorological data every 2 hours.

   Normally, meteorological observation stations generally release data at least two to three times a day.

  In the world, there are also nearly 3,000 terrestrial meteorological observation stations, which exchange meteorological telegrams four times a day at 0:00, 6:00, 12:00 and 18:00.

  Because Kou Xun spoke very solemnly, and the big leaders of the meteorological department were in the midst of shock and trust in quantum computing, they also launched their forces to provide Kou Xun with more data.

  Because of this temporary task, many meteorological observation station staff in remote areas complained a little.

   And the people in the quantum computing project team are also busy at night for this matter.

   The third data summary was brought over, and it was already past 9 o'clock in the evening.

Data such as    is slow, but computation is fast.

   During this day, the data was calculated four times.

   Kou Xunbi finally confirmed his judgment in the light of the four changes in the data.

   He said solemnly: "According to the current results, if there is nothing wrong, then 10 days later, a big cold wave will sweep across most of the country!"

  Ni Guangbei hurriedly asked: "How serious is it?"

   "Very serious! This may be the most serious in more than 50 years! No, I have to report to the leader quickly, and I have to prepare early!"

   Kou Xun hurriedly left, leaving a room full of people looking at each other.

  Quantum computers are only responsible for calculations, and only meteorological experts can understand what the calculated results represent.

   Ni Guangbei sighed: "If it's true, his judgment is accurate, but he made some contributions in time."

   Zhang Qingping also nodded: "Since we have encountered such an important matter, we have to work harder these days to see if we can continue to optimize and improve the accuracy of the calculation."

  Gu Song wiped his face: "Let's get here first today, it's not too early, everyone go back and have a good rest. I'll hear the results tomorrow."

  …

   At the National Weather Service, a top-level expert group meeting is taking place.

   If you only look at the calculated data from these few times, everyone and Kou Xun's judgments are of course the same.

   But the question is, is the data real? Is it accurate?

   After all, this counts data from ten to fifteen days later.

"This is not a trivial matter. If we submit this result, it will involve a large number of high-intensity personnel work arrangements in all aspects of the system during the last period before the New Year. Not to mention material preparation. Is it a misjudgment?"

   At present, only Kou Xun and the big leaders of the Meteorological Bureau know that this is the credit of the quantum computer.

  Others don’t know, they think it’s the result of the supercomputing they’ve been using, so they have a lot of reservations.

   Kou Xun didn't say much, just looked at the leader.

The leader    said: "We think that these numerical forecasts are no problem. Then, starting from this, we now need a more comprehensive forecasting material."

   He paused, then emphasized: "Be more detailed!"

  The big leader has spoken, and the issue has entered the next stage.

   No longer question the accuracy of the data, but purely interpret weather trends from it.

  Everyone spoke with you, and I spoke with each other, talking about the weather changes at that time, and their expressions became solemn.

   After all, it is a natural disaster of this magnitude.

   Therefore, even if it is just a misjudgment, it is necessary to make some preparations.

  Because if it is not a misjudgment, and then because the meteorological department did not give some warning in advance, the huge losses at that time will also make everyone feel that they have not fulfilled their duties.

   Besides, will there be no accusations at that time?

  …

   Early in the morning, Bao Jiaqi received a report personally sent by the head of the Meteorological Bureau.

   "The biggest cold wave in more than 50 years?" Sitting in the heated office, Bao Jiaqi's spirit suddenly lifted.

The big leader nodded solemnly: "The quantum computer has been tested for more than half a month, and the accuracy of the data is getting higher and higher. The data calculated yesterday, the data within 24 hours is roughly consistent with the latest observation results. And these The data, the experts in the bureau have the same judgment! In the face of such a natural disaster, we must prepare early."

   Bao Jiaqi pondered for a while, and asked the secretary to call Gu Song.

   He didn't ask anything else, he just asked Gu Song's opinion on the calculation result.

  Gu Song told him with great certainty: "Absolutely no problem."

   Bao Jiaqi hung up the phone and said, "I see, you should issue an early warning. For the rest, I'll arrange it."

  On January 21, for the first time in history, the National Weather Service issued a cold wave warning 10 days later, and the level mentioned red.

   There was an uproar in public opinion!
