Tornadoes are small and medium-sized strong cyclones that extend from strong cumulonimbus clouds to the ground. When tornadoes appear, there are often one or several funnel-shaped cloud columns like "noses" extending downward from the bottom of the clouds, accompanied by storms, lightning or hail. The funnel-shaped center of tornado is composed of inhaled dust and condensed water vapor, which is a visible "dragon mouth". When a tornado passes through the water, it can absorb water and rise, forming a water column, which is connected with clouds, commonly known as "dragon with water". After passing through this land, houses are often overturned, telephone poles are blown off, and people, livestock and sundries are even sucked into the air and taken to other places.
