[Zi Niu Toutiao] After 00, college students passed the typhoon eyes 5 times, and the schedule of 20,000 kilometers chased more than 100 storms

Otherwise, the right to investigate legal responsibility

Summer is the high turnover season of typhoons. There is a group of "chasing the wind". When the typhoon comes, it is not far away to track, while shooting and recording valuable data about meteorological. Recently, the typhoon "Siaba" brought the wind and rain to strongly affect the South China region of my country. The rainfall in many places in Hainan and Guangdong broke the historical record of the same period, and at least three tornado was induced in Guangdong. Although the Central Meteorological Observatory has stopped numbers at 8 am on July 4, its impact on my country has not stopped. When "Siaba" landed in Guangdong on July 2nd, "Chasing the Wind" enthusiast Su Yizheng and his companion Xiao Wang drove a car carrying a station and wind speed meter 5 times to enter the typhoon center. , Wind speed, humidity and other data, and even shooting the sun exposed video materials. On July 5th, Su Yanjiao and Xiao Wang told the story of "chasing the wind" to the Yangtze Evening News Zi Niu Journalist.

Data discovered "Siaba" data abnormal

Temporary decision to track

Around 15:00 on July 2nd, Typhoon Siaba, No. 3 this year, landed in Dianbai County, Guangdong. Due to the positive attack of the typhoon, from July 1st to 3rd, heavy rains to heavy rains in Hainan Island, central and western parts of Guangdong and southern parts, eastern and eastern Guangxi, and south of Guangxi. The millimeter site reached 268. At least 3 tornado was induced before and after the landing of Siaba.

Until 8 am on the 4th, the Central Meteorological Observatory stopped the number on the typhoon "Siaba", but its impact on our country was far from over. More than ten provinces, regions and municipalities brought a strong rainfall process.

During the critical period of "Siaba" on the 2nd, Su Shijiao, a after -00 -00s chasing enthusiast, and his companion Xiao Wang drove vehicles carrying stations and wind speed meters to continue to return to and from electricity, Maoming, Boshi and other places, and passed through typhoon. Eye, obtained data such as air pressure, wind speed, humidity in the center of the typhoon, and even photographed precious video materials such as the sun exposed face.

After Su Yizheng was a 00, he was born in Chengdu, Sichuan, and grew up in Zhejiang. He has been interested in Qiang's weather since he was a child. His other hobby is photography. Middle schools began to learn the shooting of videos and photos. In 2019, he was admitted to Communication University of China to study photography.

"Chasing the Wind" first started abroad. The first "chaser" recognized by the public is David Hoadley, the United States. He has used the data of the meteorological department and the airport in 1956 to "chase the wind" by the meteorological department and the airport, and founded the "Storm Trail" (Storm Track) magazine. Since the 1990s, "chasing the wind" in Europe, Australia, South America, and Africa has also been filmed as many film and television dramas. In recent years, China has begun to appear more continuously chasing the wind.

He began to "chase the wind" in the summer of 2018, and has tracked more than 100 storms last year, with a schedule of more than 20,000 kilometers, and his footprints spread throughout Beijing, Hebei, Shanxi, Jiangsu, Zhejiang, Shanghai, Inner Mongolia, Heilongjiang and other places. As a photographer, Su Yijiao has always hoped that he can capture the power of nature with visualization.

The little king organized by "Chinese Meteorological Lovers" is also a post -00 China "chasing the wind". , And then gradually build typhoon eyes, the growth rate is relatively fast. According to the weather forecast, "Siaba" may land near Guangdong Daibai on the afternoon of July 2, so they decided to follow up.

Su Shijiao also wants to use the "Siaba" to perform a plan to verify, testing a new "chasing the wind" solution, "new photography systems, new instruments, everything is basically new, this year can be completely tested to test completely this year. Various data such as air pressure charging and wind speed. In the past, it was used to use the handheld wind speed meter. It may only measure one point. This year's new instrument can measure the continuous changes in wind speeds. "Measurement equipment can be measured." Measuring the device

Cross 5 Typhoon Eyes

The detection data is not easy

On the evening of July 1, he flew from Hangzhou to Zhanjiang with Xiao Wang, and brought a lot of equipment with him, including sensors, wind speeds and several shooting equipment.

In the early morning of the next day, they and a local "chasing" enthusiasts deployed the measurement stations and instruments on the roof, and then marching to the Typhoon East to find the right opportunity to enter the walls and winds of the typhoon.

Typhoon is a large -scale weather system, which has a large range of influence, long duration, and relatively easy to track. The small -scale strong stream has a strong suddenness, and the duration is relatively short, so it is a bit difficult to chase.

Su Shijiao was not the first time that he had crossed the typhoon. When the typhoon "Fireworks" landed last year, he had passed through. The movement speed of "Fireworks" is a bit slower than "Siaba", and the wind is not as good as "Siaba".

The typhoon of "Siaba" has a diameter of about 30-50 kilometers. Although the wind is greatly weakened after landing, it still has amazing power. In addition, the amount of precipitation brought by "Siaba" is relatively large. Su Shijiao's partner Xiao Wang said: "We left Zhanjiang on the evening of the 3rd, but although the typhoon was gone that day, the rainstorm continued, so the precipitation was relatively powerful."

Meteorological experts determine that the typhoon landing is judged by its geometric center and the wind farm. In fact, the typhoon eyes are a circular structure. When its geometric center is still at sea, the typhoon eyes may have reached the shore.

They set off around 10:00 am on the 2nd, and entered the Typhoon Eye for the first time around 10:45, and "Siaba" officially landed at around 15 o'clock that day. , Crossing a total of 5 times.

Su Shijiao and Xiao Wang crossing and forth are not out of fun, mainly because they need to do too much work when crossing. "We need to measure the data in different areas and outside of the typhoon in the eyes of the typhoon. The accurate intensity needs to be rigorously analyzed and corrected different data in the later period. "

Although the movement of typhoons is not fast, because many equipment is needed at the same time, the two people are not enough when tracking. "I don't know which device should be operated first, because to shoot a relatively large scene and the scene in the eyes of typhoons, it depends on whether the data is operating normally, so I am busy." Su Yanqian said.

The reason for deciding to cross as much as possible is to look at the changes in air pressure from outside the typhoon to the center, and then take some typhoon lenses. "We have always followed it to the west."

When Su Shijiao tracked the typhoon "Fireworks" with his partners last year, he also stayed in the eyes of typhoons for a while, but the structure of the "fireworks" did not have "Siaba", so the data measured this time is more valuable.

They found that from the periphery of the typhoon "Siaba" to the typhoon eyes, the air pressure gradually decreased. After crossing the eyes of the typhoon, the air pressure no longer decreased and began to rise. They obviously felt that there was a process of wind and rain weakened when they crossed. The temperature in the eyes of typhoons rose, and the wind was much less.

"Siam" landed at a typhoon level, the center was relatively calm, the wind and rain were significantly small, and it was not even rainy. It was a bit windy. The sun might be faintly out of the clouds. If it is a super -level typhoon landing, the typhoon eyes will be more transparent and quiet.

Xiao Wang said: "When we first and the second time in and out of the typhoon, it was obvious that the rain would become smaller when the rain just entered, and then the rain gradually stopped, and the sky would become brighter. The phenomenon, but the sky will become significantly brighten, and the surrounding temperature will increase significantly. "

"Siaba" radar puzzle, typhoon eyes are clearly visible

They found that the air pressure data measured on the spot was a little higher than the air pressure data measured at the sea measurement station, because the sea was closer to the center of the typhoon after all, and the number of wind speed data with the number of local measurement stations was relatively more consistent with the number of local measurement stations. of.

Crossing five typhoons in a row, it is relatively prominent in the domestic chasing activities. "Few people have entered the eyes of typhoons before. Even if anyone goes in, rarely go through the typhoon eyes like us. Some data will be useful." Xiao Wang said.

Typhoon "Siaba" measures task air pressure data

China Chasing Wind Campaign is still starting

I believe it will get better and better in the future

There are risks to track strong flow weather such as typhoons. They not only accompanied strong winds, rainstorms, lightning and other phenomena, but also because the path is difficult to accurately predict. It is often necessary to adjust the tracking route randomly. Route planning.

The biggest wind of "Siaba" at the scene was about 10 levels. "When the vehicle is driving on the national highway, you can feel that the body shakes around and the steering wheel is not controlled at all."

Because "chasing the wind" for many years, Su Yizheng and Xiao Wang have already experienced it. When he chased "Siaba", he mainly focused on driving away from the national highway. Stranger, try not to open to the mountains, the safety factor increases a lot. However, it is basically heavy rain along the way, and it is still a bit dangerous to cross these rain areas. The along the way Su Yijiao and Xiao Wang "chasing the wind"

Although they have a high sense of security, sometimes in order to measure better data or take better pictures, they will still take a little danger.

When the national road was particularly high, Xiao Wang was worried that the branches fell down and smashed into the car. "When we drove halfway, we saw that there were some big trees falling on the road in front of the national highway, blocking the road, and finally relying on many passing drivers to help move the tree together, everyone can re -on the national road Driving. We will go to some remote places during the tracking process. Once we arrived in a peninsula, there was a mountain there, basically no one, and it was a dirt road. Det off. "

Many trees were blown down by the wind

Xiao Wang believes that China's "chasing wind" activity is at the beginning, and there are still many deficiencies in the "chasing" strategy and data measurement. "Lovers are tracked together, but the task distribution of most people is not very clear. The chaser may just want to see the wonderful weather or the stimulus, few people will measure the data. "

He believes that data measurement is necessary to measure the wind, and the meteorological data analysis they do is also very professional. It is helpful for the development of meteorological causes such as disaster prevention and mitigation in my country. It will be better in the future. "

Crossing the Typhoon Eye of "Siaba" 5 times, and obtaining the data and video materials of its structure, Su Yizheng was very satisfied. He will graduate from Communication University of China next year. Bi setting his work has already been determined, that is, to make a "chasing" documentary, the typhoon eye of "Siaba" will be one of the chapters.
