Who is the man who followed the tornado?

Every spring and summer, a steady moist air stream in the Gulf of Mexico moves with the northern polar air mass, often forming clouds as high as18km and as wide as100km. These clouds contain everything, which shows the most naked violence.

It must be a tornado.

From April to July, there were hundreds of tourists chasing the wind along the "Tornado Road" in the United States. Hurricanes may last for more than a week, but tornadoes change quickly, and most of them only take a few minutes, so the main content of the journey of chasing the wind is the long driving day after day.

The common equipment of wind chasers is very professional.

There are two main types of wind chasers: photographers and wind chasers. A device commonly used by wind chasers is called "Doppler on wheels", which is to scale down the Doppler radar used for meteorological observation and install it on pickup trucks. Wind chasers can take it to chase the wind instead of waiting for a tornado to arrive.

Another kind of equipment is called "tortoise shell" because of its shape. There is an instrument for measuring temperature, air pressure and humidity in the turtle shell. When the tornado passed, the tortoise shell recorded the meteorological conditions on the ground at that time.

With a few hours of boredom, waiting for dozens of seconds is thrilling.

Fans can wait patiently for a long time. Many times, the facts are not as spectacular as those in photos and movies. They spend most of their time driving on the road, eating fast food and crouching in a small space to rest. So, what makes storm fans so enthusiastic?

A tourist described it as: "It's a bit like a war. First, a few hours of boring and tense March was suddenly broken by a few minutes of panic. When everything is silent, it is really a mess. " But senior wind chasers all said in unison, "As long as you see a tornado with your own eyes, you will feel that everything is worth it."

Robert Jeff trapp is a meteorologist at Purdue University and a fan of chasing the wind. He said that chasing the wind is exciting, but it is not magical everywhere, and sometimes it is frustrating, but the feeling of success is incredible. And there is brotherly friendship between the wind chasers. Especially after a storm, everyone gathered in a local restaurant to exchange experiences and take out their own videos to enjoy. It's interesting to hear stories about chasing the wind. The process of chasing the wind can make people become patient and appreciate nature better.

The photos taken by volunteers chasing the wind are very precious.

People who follow the trajectory of tornadoes are usually regarded as reckless thrill seekers regardless of their lives, but they contribute to the weather forecast. They can provide weathermen with things that radar can't see. In addition, with the pictures taken by wind chasers, we can easily and deeply explain any original research results and improve our prediction ability.
