Material Detail

This NOVA television broadcast examines the rare 'supertwister', an extreme tornado classed F4 or F5 on the Fujita scale. Two storms are discussed: the 1999 Oklahoma City tornado (F5) and the 2002 LaPlata, Maryland tornado (F4). Articles discuss the seemingly high incidence of tornadoes in the United States and the development of tornado forecasting. There is also an audio feature on storm tracking, an interview with an expert in analysis of storm damage, and an interactive feature in which viewers examine photos of tornado damage and attempt to estimate the storm's Fujita scale rating.
