Hi,
Well the force is centripetal force during a body is initially attacked by the tornado,when the body started swinging in the tornado from the surface of the earth,the time when body covers some distance from downward to upward is the time when centrifugal force is applied.... That means tornado have both the centripetal force and centrifugal force.....
Thanks you!
This is a term from classical mechanics. A fictitious force is a force that is only present in a so-called non-inertial frame. This means that the observer is experiencing some kind of acceleration. The point is that if the observer is accelerating then he might see some forces that are not really forces at all. If you are in a rotating frame you are accelerating, and you feel a centrifugal force. However anyone looking at you while not rotating themselves will say that there is no such force at all. Imagine you are on a horse in a merry-go-around and the thing malfunctions and starts to rotate very rapidly. You will feel the centrifugal force trying to blow you away from the center. However someone standing next to the merry-go-around sees no such force. What he sees is you holding on to the horse, but it is YOU holding onto the horse that is providing a force, if you would let go you would just fly in a straight line and no force would work on you. It is a little difficult to explain it very well in words, in the relevant links I have posted a link that points to the wikipedia article for the Coriolis force (a fictitious force) and figure 1 there shows a nice picture of the above. In General Relativity however, there is no preference for inertial frames anymore and you are valid in claiming there is a force pushing outwards. This force is then gravity. This is direct consequence of the equivalence principle that states that gravity and acceleration are indistinguishable (in a suitable limit).

The two major forces that act upon a body are centrifugal force and centripetal force. Centrifugal force causes a body to fly outwards, or moves a body away and centripetal force counteracts centrifugal force, preventing the object from flying out and keeping it moving with a constant speed, in a circular path.Search templates (CTRL+Space) New TemplateHide button

When a body is forced to follow a curved path and be directional to the velocity of the path it is known as a centripetal force. Simply put, centripetal force is the cause of circular motion. An example is a loop within a roller coaster that goes upside down, the centripetal force is applied to the track making the coaster travel through at speed.
Gravity, friction, air resistance, centrifugal force, may be more.
When rounding a curve, the centripetal force comes into play. This force is directed towards the center of the curve and is necessary to keep an object moving in a curved path rather than continuing in a straight line.
The wind in a tornado moves in a circular fashion as it is pulled inward by the pressure gradient force resulting from the low pressure at the center of the tornado.
Centripetal force is a force that makes a body follow a curved path: it is always directed orthogonal to the velocity of the body, toward the instantaneous center of curvature of the path. The term centripetal force comes from the Latin words centrum ("center") and petere ("tend towards", "aim at"), signifying that the force is directed inward toward the center of curvature of the path. Isaac Newton's description was: "A centripetal force is that by which bodies are drawn or impelled, or in any way tend, towards a point as to a center."
the tornado kind
A tornado is a kind of vortex so yes, in some ways.
A tornado is itself a kind of vortex, and can have smaller vortices inside of it.
They are the same factors affecting any other kind of force. If the centripetal force is gravitational, then it depends on the masses of the two bodies involved and the distance between them. If it's electrostatic, then it depends on their charges and the distance between them. If it's the force that bends a car around a curve, then it depends on the bank in the pavement and the coefficient of friction between the road and the tires.
A tornado emergency is a special kind of tornado warning that is issued when a large tornado is threatening a populated area. A tornado emergency indicates a more dangerous situation than an ordinary tornado warning.
