Open an aircraft carrier to fight against Japan

Prince Qing asked, "What does this word mean?"

Lin Yuan replied: "This disaster will come from the sea. Does your lord know about the gale at sea?" "Blade" is the name of typhoon in this era.

Prince Qing said: "Why don't you know, Shandong, Zhejiang, Jiangsu and other provinces have riots several times a year, and many people die every time. I don't know how much money the court spent on this matter."

Lin Yuan said: "Your Majesty, don't worry, these few evil things are the precursors of the wind."

Prince Qing hurriedly said: "It would be great if this is the case, tell me quickly, where did this gale come ashore?"

Lin Yuan replied: "This is not sure yet, after a few days, I will tell the prince."

Prince Qing was in a good mood when he heard this, and had a drink with Lin Yuan before leaving.

Lin Yuan couldn't foresee the foresight. The reason why he dared to be so sure that typhoons would happen was because this season was the period of high incidence of typhoons along the coast of China, and China was a country where typhoons landed very frequently. As many as seven.

Lin Yuan waited until Prince Qing left, then contacted Yuan Yi, the weather officer on the Beijing ship.

Lin Yuan said: "Monitor the southeast coast, and if there is a typhoon, please notify me in time."

This sentence confused Yuan Yiwen, because typhoon is not a strictly defined concept in terms of meteorology. The essence of typhoon is a strong cyclonic vortex on the tropical ocean surface, and this cyclone can bring huge disasters. There are several types of vortices. According to the standards of the World Meteorological Organization, according to the maximum wind force of the cyclone center, they are divided into tropical depression, tropical storm, severe tropical storm, and typhoon from low to high.

Yuan Yi guessed Lin Yuan's intentions, and asked, "Will you be notified only when a typhoon is found, or when a tropical cyclone is found?"

Lin Yuan also remembered the looseness in what he said, and quickly corrected it: "As long as there is a tropical depression that is likely to endanger the coast, please notify me."

Yuan Yi said: "This is probably very difficult. Although we can detect the tropical depressions that have formed from the radar echoes, they are all formed on the vast ocean. We cannot know their movement paths in advance. Tropical depressions can be found in Landing at any one of thousands of kilometers of coastline, our radar cannot monitor such a wide range of sea areas!"

Lin Yuan smiled and said: "Why did you forget our identities, we are time travelers, our behavior can affect the progress of social history, but it is difficult for us to affect the progress of natural history, the date of typhoon will not change, You must have a database of tropical depressions. Historians have found out the places where the typhoon landed in 1895 from various archives and local chronicles of the Qing Dynasty, and recorded them in the database. You can check it out. Has the detection range been shortened?"

Yuan Yi quickly laughed and said, "Why did I forget this method, we will notify you as soon as we find out."

Yuan Yi then went to check the data. According to historical records, three days later, a typhoon with a central wind force of level 12 will make landfall in Shandong. Afterwards, they searched the sea area outside Shandong, and finally found a typhoon that was forming. Tropical depression.

Tropical depressions can be upgraded to tropical storms, severe tropical storms, and eventually typhoons. They measured the speed of this tropical depression and expected it to land in two days.

After Lin Yuan received the news, he immediately informed Prince Qing that no one has ever succeeded in predicting a typhoon. If the person who did this was not Lin Yuan but someone else, he would have been regarded as a charlatan He was pulled to Caishikou and beheaded for public display.

Although it is expected to take two days, Yuan Yi is not sure, because the tropical depression is escalating, and the behavior of the moving process cannot be explained too clearly by modern science. The tropical depression is likely to accelerate during the movement. , turn around, and even induce a new low pressure, so Lin Yuan didn't dare to delay for a moment, and immediately ordered the staff at the post station in the capital to send a message to the governor of Shandong urgently within eight hundred miles.

In the three hours after Yuan Yi reported the discovery of a tropical depression to Lin Yuan, the tropical depression was upgraded to a typhoon, with the central wind force exceeding magnitude 12, rushing toward the Shandong Peninsula at a speed of meters per second.

The destructive power of typhoons mainly comes from strong winds and heavy rains. In the absence of breakwaters on the shore, the large waves caused by strong winds may also cause certain damage to buildings and personnel on the shore.

Lin Yuan was worried that the governor of Shandong had no way to deal with these things, so he rushed to Qingdao, where the typhoon was about to land, a day later. Situation: "Lord Lin, all the fishing boats near Jiaozhou Bay have returned to the port, and they are strictly prohibited from leaving the port. The residents on the shore have already evacuated for thirty miles."

Lin Yuan nodded and said, "Let's go take a look."

Qingdao city is like a dead city at this time, all the shops have closed down, many people stay at home and cannot come out. There may be nothing left in the storm.

What worries him even more is that cities in this era do not have underground drainage systems, and the radar of the Beijing ship uses the echoes of raindrops in the clouds to detect the amount of water carried by the typhoon. Will reach 24 mm!

Although 500 millimeters is not big, it is extremely terrifying in terms of precipitation. You must know that in the modern weather, the precipitation in 24 hours is only 50 millimeters!What's even more frightening is that 500 mm of rainwater will flow downhill, forming floods. By then, more than half of Qingdao City will be deserted. The city is like this, and the countryside is even more dangerous.

The rural population in this era is already large, and they are all near the river. With such a large amount of rainfall, it is a certainty that the big river will overflow the embankment, so the population in the lower places must be evacuated.

This time, Lin Yuan had experienced how fragile ancient Chinese society was in the face of catastrophes. Although he thought of this, due to the backward communication means, they could not notify many remote villages and towns; Lin Yuan wanted to organize people to strengthen the embankment, But I was surprised to find that people didn't have sandbags to pack the soil, and they didn't have a shovel to dig the soil!

Could it be that we can only resign ourselves to fate in front of the typhoon!Lin Yuan thought about it, and ordered to the governor of Shandong: "Immediately evacuate the residents of the villages and towns along the river, as many as can be evacuated, and let them go to the nearby high ground; Prefect Yamen."

Lin Yuan knew that the magistrate's yamen was located on a very high ground, and there would be no great danger in the heavy rain, but he did not expect the governor to say, "It's not proper to let these common people enter the yamen!"

Lin Yuan said angrily: "If you tell you to do it, you will do it, if you dare to say more, I will kill you!"

The governor hurriedly sent someone to do it, and some villages and towns were too far away to be notified. We had to resign ourselves to fate. At night, the front of the typhoon landed on the coast 27 kilometers north of Qingdao. Within 10 minutes It covers the whole Qingdao.

The strong wind blew the raindrops and raged on the ground. The residents crowded in the magistrate's office. Lin Yuan looked at the heavy rain in front of him, but thought of a more terrible disaster that would follow.
