Give a basic description of a tornado outbreak.?
What will be the ideal response?
ANSWER: Sometimes a large, well-organized frontal system will spawn multiple supercells, each producing its own family of tornadoes. When a large number of tornadoes develop in association with a particular weather system (typically six tornadoes or more, although there is no strict definition), it is referred to as a tornado outbreak. An outbreak may extend over multiple days, as long as no more than a few hours (typically six) elapse without at least one tornado being observed in the outbreak region.?
