What is a vortex of the tornado?
In tornado: Violent (EF4 and EF5) tornadoes. …to what is termed a multiple-vortex tornado. In these secondary vortices, air spins rapidly around the axes while the vortices themselves rotate around the periphery of the central eye.
What is a vortex and how does it relate to hurricanes and tornadoes?
Tornadoes and hurricanes are weather phenomena that are examples of physical vortexes. High winds, torrential rain, floods, and storm surges caused when hurricanes come near or over land result in significant damage over large areas.
How many vortexes can be in a tornado?
As a result, they are responsible for most (if not all) cases where narrow arcs of extreme destruction lie right next to weak damage within tornado paths. Subvortices usually occur in groups of 2 to 5 at once (the 6 or 7 evident here being uncommon), and usually last less than a minute each.
What causes a multi vortex tornado?
Subvortices tend to form after vortex breakdown reaches the surface and are resultant from the ratio of cyclonically incoming and rising air motions. Multivortex structure is not unique to tornadoes, occurring in other circulations such as dust devils, but is a natural result of the physics of vortex dynamics.
What is the most dangerous type of tornado?

How much damage would a f12 tornado do?
An F12 tornado would have winds of about 740 MPH, the speed of sound. Roughly 3/4 of all tornadoes are EF0 or EF1 tornadoes and have winds that are less than 100 MPH. EF4 and EF5 tornadoes are rare but cause the majority of tornado deaths….
