Jet stream getting faster, causing more powerful storms

The video discusses a study led by Dr. Samantha Hallam from May Nuth University, which used powerful computers to model jet stream speeds from 1871 to 2021. The study found that the northern hemisphere jet stream has grown stronger, with an 8% increase in average winter speed since 1871, now averaging 212 km/h. The jet stream's position has also shifted northward by up to 330 km, affecting weather patterns by increasing storm activity and altering temperature patterns, leading to strong winds and flooding events.
