Presenter Helen Czerski goes to the USA to experience the power of a real tornado. She meets up with an expert, Josh Wurman, to show how the physics of Earth’s unstable atmosphere form tornadoes, but only when the conditions are right.
Can be used to support work on extreme events or severe weather. A number of concepts are covered: weather forecasting and tracking, the pre-requisites for the formation of a tornado, the weather features associated with a super-storm and what happens when a storm 'collapses'. It lends itself to a 'cloze' exercise (fill in the gaps) which covers pre-requisites for a tornado to form (what sort of air masses, pressure, rotation?). What sort of weather is associated with a super-storm (rain, hail, high winds, tornadoes) and how are these storms forecast or tracked? What happens when a storm edge collapses?
