random fact 19

A tornado is a rotating air column which is in contact with the ground and a cumulonimbus cloud. Synonyms to the word are twister and cyclone. It is described a a dangerous phenomenon often with violent results on the areas it passes. It is described as funnel-shaped, which is an extension from a cumulonimbus cloud. The Fujita Scale is used to grade the intensity of a tornado by assessing its damage to man-made structures.

The Philippines, which is a common alley of thunderstorms, is also susceptible to tornadoes as cumulonimbus clouds are formed in thunderstorms. The latest recorded tornado in the Philippines was in August 2010, in Oton, Iloilo.
