They chase tornadoes to collect information about wind speed and air pressure. This helps scientists make better forecasts and warn people before a storm hits. However, the job is very risky. Tornadoes can change direction quickly, and storm chasers may not have enough time to escape. In 2013, a famous storm chaser named Tim Samaras lost his life while chasing a huge tornado. His work still plays an important role in weather science. Storm chasers continue their work to learn more about storms and keep people safe. I think they are very brave. 1 学科网（北京）股份有限公司 $
