Informally some people do call them cyclones, by this is technically incorrect. While they share some traits, tornadoes and cyclones are different types of weather pattern.
No, tornadoes are associated with cyclones and not anti-cyclones. Tornadoes typically form in association with severe thunderstorms within a cyclonic circulation pattern. Anti-cyclones are areas of high pressure with descending air, which are typically not conducive for tornado formation.
A tornado in the southern hemisphere is still called a tornado.
No, tornadoes do not have real eyes. The center of a tornado is called the "eye," but it is a calm area of low pressure where the air is sinking rather than rising like in the rest of the tornado. It is a term borrowed from hurricanes which do have a clear circular center called the eye.
Although tornadoes often have a structure that resembles the eye of a hurricane, this structure, called a weak echo hole is not the same as the eye of a hurricane. Although the area surrounding the center does have violent winds even if the actual center does not, it is not called an eyewall.
Tornadoes form when thunderstorms (usually from a collision of air masses of different temperatures and/or dew points) encounter wind shear, which is when wind speed and/or direction change with altitude. This creates horizontally rolling air that can be tilted vertical by a thunderstorm updraft. The updraft takes on this rotation to become a mesocyclone. Under the right conditions this mesocyclone can tighten and intensify to form a tornado. Se the links below for the formation of tropical and extratropical cyclones. Ignore the parts about mesocyclones and tornadoes as they technically are not cyclones.
Some cyclones produce tornadoes, but most do not.
Sometimes they are called cyclones, though it is incorrect to do so, as a cyclone is a large-scale weather system
Tornadoes are sometimes called twisters and (incorrectly) cyclones.
Another word for tornado is also called cyclones.
Tornadoes can be called twisters, but tornado is the preferred term. Hurricanes are also called tropical cyclones, though that is a somewhat broader term.
Tornadoes are often called twisters. Some people call them cyclones, though this is not a correct name as it already applies to something else.
Cyclones spin counterclockwise in the northern hemisphere.
Cyclones are far larger. Cyclones are hundreds of miles across while tornadoes are usually less than a quarter of a mile wide.
No. Tornadoes and cyclones are different things. A cyclone is a large-scale low pressure system while a tornado is a small-scale vortex within a thunderstorm. Most cyclones are mid-latitude cyclones.
Tornadoes are sometimes called twisters. Some people will also call them cyclones, though this is technically incorrect. If a tornado occurs on water it is called a waterspout.
They are not. Tornadoes are much smaller than cyclones. A true cyclone is generally a few hundred miles across while tornadoes are rarely over a mile wide. Tornadoes are smaller because they form within individual thunderstorms while cyclones are their own weather systems.
No, tornadoes are associated with cyclones and not anti-cyclones. Tornadoes typically form in association with severe thunderstorms within a cyclonic circulation pattern. Anti-cyclones are areas of high pressure with descending air, which are typically not conducive for tornado formation.
