The term cyclone refers to a wide variety of weather phenomena. Many cyclones are not particularly violent, though tropical cyclones (hurricanes and typhoons) generally are. Generally speaking tornadoes are more violent than cyclones but cyclones cover a much larger area and so release much more energy.
Some cyclones produce tornadoes, but most do not.
Cyclones generate thunderstorms by various means, either by themselves being large convective systems, such as in tropical cyclones (hurricanes etc.) or, more commonly, in the fronts generated by mid-latitude cyclones. The thunderstorms generated along fronts tend to be stronger than those that are not, and a stronger storm is more likely to produce a tornado. Wind shear affecting these storms can set them rotating. This rotation within the thunderstorms can then produce tornadoes.
Cyclones are far larger. Cyclones are hundreds of miles across while tornadoes are usually less than a quarter of a mile wide.
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.
Cyclones spin counterclockwise in the northern hemisphere.
The answer is simple. No. Tornados are on land, while cyclones are in water.
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.
No. All hurricanes and other tropical cyclones above tropical depression strength get named, however extratropical cyclones are not named. Tornadoes never get names.
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.
yes
Yes. Oman can occasionally get tropical cyclones. Tropical cyclones can produce tornadoes. That said, such tornadoes are usually weak, so tornadoes like the ones that devastate communities in the U.S. are unlikely.
cyclones are formed over the pacific ocean
