They both have rotating winds. Other than that they are completely different. Anticyclones are large-scale high-pressure systems that bring calm, clear weather. Tornadoes are small centers of low pressure with extremely violent winds.
Tornadoes are neither cyclones nor anticyclones. They are a type of severe weather phenomenon that consists of a rotating column of air extending from a thunderstorm to the ground. Cyclones and anticyclones refer to large-scale weather systems characterized by rotating areas of low and high pressure, respectively.
Cyclones produce thunderstorms that can potentially produce tornadoes. Mid latitude cyclones often produce fronts from their rotation by forcing contrasting air masses together. Thunderstorms often form along these fronts. This is how most tornadoes form. Anticyclones generally tend to suppress thunderstorms ans thus tornadoes rather than produce them.
Isobars form a concentric pattern around the center
There are rotating cyclones and anticyclones on Jupiter, but they are a bit different from any storm found on Earth.
Tornadoes are most common in Texas
No. An anticyclone is a large scale high pressure system that generally brings calm, sunny weather. Anticyclones rotate clockwise in the northern hemisphere and counterclockwise in the southern. Tornadoes have more in common with cyclones than they do with anticyclones. A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground. In weather terms it is a small scale vortex. Tornadoes generate intense low pressure and, about 99% of the time the rotate counterclockwise in the northern hemisphere and clockwise in the southern. In this sense they are similar to cyclones, though on a much smaller scale.
Anticyclones produce high barometric pressure.
No. It is not common to see tornadoes unless you are a chaser or a spotter.
Anticyclones are high pressure arear and depressions are low pressure areas.
Tornadoes are common in the United Kingdom.
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.
Relatively little is known on how Neptune's atmosphere might operate on the scale that tornadoes do. However, the dynamics of Neptune's atmosphere are rather different from those on Earth, with large storms developing from anticyclones rather than cyclones and the lack of a solid surface. Tornadoes as we know them likely do not occur there, but we cannot rule out somewhat similar intense vortices.
