Introduction
What are tornadoes and where are they commonly found?
How are tornadoes formed?
What types of tornadoes are there?
There are different types of tornadoes which are observed all over the world. Some of them are:
Waterspout Tornado:
It is tornado that is formed over a water body, usually an ocean or sea.They are similar to the mesocyclonic thunderstorm tornadoes but are formed over a water body. A waterspout is not a destructive tornado as it spans itself over less than 2 km. Tornadoes of these type cause damage that tends to be EF2 or
Landspout Tornado:
These are similar to waterspout tornadoes in terms of relative weakness, short lifespan, and a small, smooth condensation funnel which often does not reach the surface. There is no rotating updraft – the spinning motion originates near the ground. They are usually weaker than normal tornadoes but can create winds which can cause serious damage
Dust-Devil Tornado:
They are similar to the normal tornadoes, of vertically rotating column of air. But they occur under clean skies and are very weak. They form when a strong hot updraft is formed near the ground on a hot day. A Dust-Devil tornado occurs when the sun heats dry land surfaces forming a twisting column of air. These types of tornadoes are commonly known as willy willy in Australia.
Gustnado Tornado:
This type of tornado has a gust like vertical updraft of air. They are not connected with a cloud base. They are formed when cold dry updraft of air mixes with the moist cool air which is stationary resulting in a rolling effect. A Gustnado is short-lived and lasts from few seconds to minutes.
Facts about tornadoes
• A tornado is a rapidly spinning tube of air that touches both the ground and a cloud above.
• Most tornadoes have wing speeds less than 100 miles per hour (161 kilometres per hour).
• A tornado that occurs over water is often called a waterspout.
• In 1989 the deadliest tornado ever recorded in the world killed around 1300 people in Bangladesh.
How Does The Film Specify Its Disaster
Also it's realistic that cars and other heavy objects are flying because it's true that these kind of things happen in a tornado.
Finally the reaction of the people is quite realistic as well. Due to its law efficiency of tornadoes in Los Angeles citizens will not know its danger and would want to record the disaster.
