Are yu afraid f big strms? Many peple are. But did yu knw sme peple g ut t chase trnades? Such strms can hit suddenly and mve very quickly, s strm chasers always have t be prepared.When a trnad is abut t hit, prfessinal strm chasers try and get clse t it t cllect imprtant infrmatin. 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. This helps scientists t make better frecasts. 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.
