A cyclone is a large-scale low-pressure weather system with an organized cyclonic circulation (clockwise in the northern hemisphere and counterclockwise in the southern). A hurricane meets all these characteristics, and is more specifically a tropical cyclone. Tornadoes are sometimes called cyclone, but this is not entirely correct. A tornado is a low pressure area with an organized cyclonic circulation, but it is a small-scale vortex dependent on a parent thunderstorm.
No. All hurricanes and other tropical cyclones above tropical depression strength get named, however extratropical cyclones are not named. Tornadoes never get names.
Tornadoes, by a considerable amount.
cyclones are formed over the pacific ocean
They do, but most tornadoes don't make international news and generally, the strongest tornadoes that do most of the serious damage occur in the U.S. Hurricanes occur in the southern hemisphere, but are called cyclones or tropical cyclones rather than hurricanes.
Tornadoes can be called twisters, but tornado is the preferred term. Hurricanes are also called tropical cyclones, though that is a somewhat broader term.
All are forms of potentially dangerous weather.
Yes, Hurricanes and tornadoes are the two most violent types of storm on earth.
Many tornadoes have a structure similar to the eye of a hurricane, but the only true eyes are in tropical cyclones. In Tornadoes and other storms it is called a weak echo region.
Tornadoes are called "twisters." Hurricanes are sometimes called "tropical storms" before they reach violent wind speeds, and are referred to as "typhoons" in the Pacific. Both tornadoes and hurricanes can be called "cyclones" because they both have violently rotating wind.
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 do. Tropical cyclones (hurricanes, typhoons etc.), extratropical cyclones/lows, Some thunderstorms (mostly supercells), and tornadoes are all storms that rotate.
Tornadoes, hurricanes, floods, volcanic eruptions, earthquakes, tsunamis, mudslides and wildfires are different types of natural disasters.
