Tornado is a form of natural disasters that usually accompanied by strong winds, heavy rain and sometimes snow, sleet, hail or no precipitation at all.
Tornadoes can generally form and develop in any geographic location, perhaps most frequently within areas located at mid-latitude when warm moist air collides with cooler air. They are responsible for the development of many severe weather phenomena and pose great hazards to populations and landscapes.
Damages that result from tornadoes are mainly inflicted by down-burst winds, large hailstones and flash flooding. Viewers can see the tornado\'s power and its negative consequences through series of photos below.
