Strm chaser Tim Samaras designed and built many different instruments fr studying trnades. Thrughut his career, the engineer chased dwn mre than 120 trnades. Often, he filmed the strms while they were happening just a few kilmetres away.

During a strm, strm chasers put special equipment in the way f the trnad. The equipment cllects infrmatin abut things such as wind speed and air pressure.

It can even help peple understand hw pwerful the winds can be, and as a result, change hw we build ur huses.Strm chasing can be exciting, but als very dangerus. The strm chasers’ knwledge and experience are nt always enugh t keep them safe. On 31 May 2013, Samaras and his team were chasing the El Ren trnad in Oklahma, USA. T their surprise, the trnad behaved in an unexpected way. It grew rapidly and changed its speed and directin.

All three men in the car died.The stry f Tim Samaras is very sad, but his wrk cntinues t play an imprtant rle in weather science. Thugh strm chasing remains a dangerus jb, the gal f strm chasers is t learn mre abut strms t keep peple safe. Fr peple like Samaras, that gal makes it all wrth it.

A trnad is a type f strm. It can hit and mve very quickly. Strm chasers get clse t trnades t cllect imprtant . This can help scientists t make better . It can als change hw peple build . Hwever, strm chasing can be a very jb. In 2013, Tim Samaras and his team when they were chasing the El Ren trnad. But strm chasers tday cntinue t d such wrk. Their gal is t keep peple .
Discuss the questins.
1. What d yu think f Tim Samaras’s jb as a strm chaser?2. What d yu need t be a gd strm chaser?3. D yu knw f any ther dangerus jbs? Why d peple d them?
I think his jb is exciting, but als very dangerus.
T be a gd strm chaser I need t have a lt f knwledge abut weather science, knw hw t use special equipment, and always be prepared fr danger.
Yes, like firefighters r deep-sea fishermen. These jbs are dangerus because they invlve risks like fires, high waves, r bad weather. Peple d them because they want t prtect thers r because they want t supprt their families.
