TORRO
The Tornado and Storm Research Organisation (TORRO), founded in 1974, is a privately-supported research body serving the national and international public interest. Originally called the Tornado Research Organisation it was expanded in 1982 following the inclusion of the Thunderstorm Census Organisation (TCO). Data-collection, research and co-ordination is undertaken by the Directors of TORRO, which is supported by some 300 to 400 observers, investigators and other contributors. Most supporters are British, with a smaller number from elsewhere in Europe and across the world.
