AbstractTornadoes are columns of air that spin at a high rate of speed. They are small in scale but can be very violent. The area affected by a tornado's passage is between about 40 and 400 metres in width and between 1.7 and 36 kilometres in length. During a tornado the damage is due to wind as well as an extremely sudden drop in pressure. Tornadoes vary in intensity, measured on the Fujita or F scale, graduated from 0 to 5 based on the level of damage. The main season for tornadoes is from April to October, and every province is subject to the risk of tornadoes. This layer shows some of the major tornadoes that happened in Canada since the beginning of the 20th century to 1999.
Summary(Plain Language Summary, not published)
The map was originally published online in the Atlas of Canada, 6th Edition as an interactive digital map derived from a shapefile and mapped online using MapServer, a platform for publishing spatial data to the web. In order to preserve the geographical content of this Edition during its publication from 1999 to 2009 all the maps have been converted from their online interactive form to a raster and made available in PDF and JPEG.
