2. What will you do when a tornado comes
Yes, ... / No, ...
But some people go out to chase tornadoes. Why What do they do Let's read their story together.
Are you afraid of big storms Many people are. But did you know some people go out to chase tornadoes Such storms can hit suddenly and move very quickly, so storm chasers always have to be prepared.
When a tornado is about to hit, professional storm chasers try and get close to it to collect important information. Storm chaser Tim Samaras designed and built many different instruments for studying tornadoes. Throughout his career, the engineer chased down more than 120 tornadoes. Often, he filmed the storms while they were happening just a few kilometres away.
During a storm, storm chasers put special equipment in the way of the tornado. The equipment collects information about things such as wind speed and air pressure. This helps scientists to make better forecasts. It can even help people understand how powerful the winds can be, and as a result, change how we build our houses.
Storm chasing can be exciting, but also very dangerous. The storm chasers’ knowledge and experience are not always enough to keep them safe. On 31 May 2013, Samaras and his team were chasing the El Reno tornado in Oklahoma, USA. To their surprise, the tornado behaved in an unexpected way. It grew rapidly and changed its speed and direction.
On that terrible day, the largest tornado ever recorded appeared. It was 4.2 kilometres wide and had winds topping 480 kilometres per hour. While the tornado was moving towards them, Samaras and his team were driving as fast as they could. Sadly, when the tornado hit their car, it threw their car into the air like a toy. All three men in the car died.
The story of Tim Samaras is very sad, but his work continues to play an important role in weather science. Though storm chasing remains a dangerous job, the goal of storm chasers is to learn more about storms to keep people safe. For people like Samaras, that goal makes it all worth it.
