where strong wind sheer at the ground meets a strong updraft (due to unstable air and downpours) shooting up into the atmosphere. The winds then become a powerful, destructive rotating column of air – extending skyward while maintaining contact with the ground. The UK is no stranger to tornadoes – around 30 are reported every year – but don’t always affect populated, urban areas. READ MORE
