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

Lin Yuan replied: "This disaster will come from the sea, does the prince know the fierce wind on the sea?" "Hurricane" is what typhoons call in this era.

Prince Qing said: "Why don't you know how to do it, Shandong, Zhejiang, Jiangsu and other provinces make trouble several times a year, and many people will die every time, and the court doesn't know how much silver Lu Dao has spent on this matter." ”

Lin Yuan said: "The prince doesn't have to worry, these few demonic things are the precursors of the storm. ”

Prince Qing hurriedly said: "It would be great if this was the case, hurry up and tell this king, where did this hurricane come ashore?" ”

Lin Yuan replied: "This is still uncertain, in a few days, I will tell the prince." ”

When Prince Qing heard this, he was in a good mood, and he had a drink with Lin Yuan before he took his leave.

Lin Yuan also couldn't foresee that the reason why he dared to have such a certain typhoon was because this season was the peak period of typhoons along China's coast, and China is a country where typhoons make landfall extremely frequently, with an average of seven typhoons landing in China every year.

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

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

This sentence confused Yuan Yiwen, because in meteorology, typhoon is not a strictly defined concept, the essence of a typhoon is a strong cyclonic vortex on the tropical ocean, and this kind of cyclonic vortex that can bring great disasters There are several kinds, according to the standards of the World Meteorological Organization, according to the maximum wind strength of the cyclone center, from low to high it is divided into tropical low pressure, tropical storm, strong tropical storm, and typhoon.

Yuan also guessed Lin Yuan's intentions and asked, "Is it only a typhoon to notify you, or a tropical cyclone to notify you?" ”

Lin Yuan also remembered the unstrict part of his words, and hurriedly corrected it: "As long as there is a tropical depression that can endanger the coast, notify me." ”

Yuan Yi said: "I'm afraid this is difficult, although we can detect the tropical depression that has formed from the radar echo, but the tropical depression is generated in the vast ocean, we can't know their movement path in advance, the tropical depression can choose any landing on the coastline of thousands of kilometers, our radar has no way to monitor such a large range of sea areas!" ”

Lin Yuan said with a smile: "How can you forget our identity, we are traversers, 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 the typhoon will not change, you must have a database of tropical depression, historians have found out the place where the typhoon landed in 1895 from various archives and local chronicles of the Qing Dynasty, and recorded them in the database, you go to check it, won't you be able to shorten the detection range?" ”

Yuan Yi hurriedly smiled and said, "How did I forget this method, we will notify you as soon as we find it." ”

According to historical records, three days later, a typhoon with a central wind force of 12 will make landfall in Shandong, and then they searched the sea outside Shandong and finally found a tropical depression that was forming.

The tropical depression can escalate into a tropical storm, a severe tropical storm, and eventually develop into a typhoon, and they measured the speed of this tropical depression, which they expect to make landfall in two days.

After Lin Yuan received the news, he immediately informed Prince Qing that no one could ever succeed in predicting a typhoon, and if the person who did this was not Lin Yuan but someone else, he would have been beheaded at the entrance of the vegetable market as a charlatan.

Although it is expected to take two days, Yuan Yi is not very sure, because the behavior of the tropical depression in the process of escalation and movement, modern science has not been able to explain too clearly, the tropical depression is very likely to accelerate and turn in the process of movement, and even induce a new low pressure, so Lin Yuan did not dare to delay for a moment, and immediately ordered the personnel of the Beijing Post Station to send a message to the governor of Shandong in an urgent manner.

Within three hours of Yuan Yi's report to Lin Yuan on the discovery of the tropical depression, the tropical depression escalated into a typhoon, with a central wind force of more than 12 and rushing towards the Shandong Peninsula at a speed of 20 meters per second.

The destructive power of typhoons mainly comes from strong winds and heavy rains, and under the condition that there is no embankment on the shore, the large Lang swept by strong winds may also cause some damage to buildings and people on the shore.

Lin Yuan was worried that the governor of Shandong would not have a way to deal with these things, so he rushed to Qingdao, the place where the typhoon was about to land, a day later, the governor of Shandong also came to Qingdao at this time, and when he saw Lin Yuan coming, he had a bottom in his heart, and hurriedly reported the situation: "Lord Lin, all the fishing boats near Jiaozhou Bay have returned to the port, and they are strictly ordered not to leave the port, and the residents on the shore have evacuated inward for thirty miles. ”

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

Qingdao City is like a dead city at this time, all the shops have been closed, many people are shrinking at home and not coming out, the more Lin Yuan looks at it, the more anxious he becomes, most of these people's houses are wooden, and there are many adobe houses, there may be nothing left in the coming storm.

What worries him even more is that the city of this era has no underground drainage system, and the radar of the Beijing ship uses the echo of raindrops in the clouds to detect the amount of water carried by the typhoon, and it is expected that within 24 hours of the typhoon's landfall, the precipitation will reach 500 mm!

Although 500 mm is not big, but it is extremely terrifying in terms of precipitation, you must know that the torrential rain in modern meteorology, the precipitation in 24 hours is only 50 mm! What's even more terrifying is that 500 millimeters of rain will flow to the lower places, so that a flood will be formed, and then more than half of Qingdao City will probably be an ocean, and if this is the case in the city, the countryside will be even more dangerous.

In this era, the population of the countryside was already large, and it was all near the river, and with such a large rainfall, it was a sure thing that the river overflowed the embankment, so the population in the lower places had to be evacuated.

Lin Yuan experienced how fragile ancient Chinese society was in the face of catastrophe this time, although he thought of this, but due to the backwardness of communication means, many remote towns and villages could not be notified; Lin Yuan wanted to organize people to strengthen the river embankment, but he was surprised to find that people did not have sandbags to load soil, nor did they dig with shovels!

Can you only resign yourself to fate in the face of a typhoon? Lin Yuan thought about it and ordered the governor of Shandong: "Immediately evacuate the residents of the villages and towns along the river, as much as they can, and let them go to the nearby high ground; Evacuate all the residents in the low-lying areas of Qingdao and move them to the prefect's yamen. ”

Lin Yuan knew that the terrain of the Yamen of the Prefect's Mansion was very high, and there would not be much danger in the heavy rain, but he didn't expect the governor to say: "Let this group of ordinary people enter the Yamen, what kind of system is this!" ”

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

The governor hurriedly sent people to do it, and there were some villages and towns, which were too far away to be notified, so they had to resign themselves to fate, and in the evening, the front of the typhoon made landfall on the coast 27 kilometers north of Qingdao, and covered the whole of Qingdao within 20 minutes.

The wind blew the raindrops, raging on the land, and the residents crowded into the prefect's yamen, Lin Yuan looked at the heavy rain in front of him, but thought of a more terrible disaster that followed.
