Within a tropical cyclone the winds at lower levels are slower than those at upper levels, especially if the storm is moving onto land. At these lower speeds, the low-level winds blow more toward the center of the cyclone, while upper-level winds move in a more circular fashion. This creates wind shear, which can lead to rotation in some of the storm cells within the cyclone. This rotation can lead to the formation of tornadoes.

Why don't hurricanes or tornadoes enter the southern hemisphere?
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.
Do tornadoes have eyes?
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.
Which storms feature strong cyclonic winds spinning counterclockwise?
A number of storms in the northern hemisphere have such characteristics including tropical cyclones (hurricanes an typhoons), some extratropical cyclones, and most tornadoes (on rare occasions they are anticyclonic).
Which way do cyclones and tornadoes blow in the northern hemisphere?
Cyclones spin counterclockwise in the northern hemisphere.
How do tornadoes form in cyclones?
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.
Are all hurricanes cyclones and tornadoes named?
No. All hurricanes and other tropical cyclones above tropical depression strength get named, however extratropical cyclones are not named. Tornadoes never get names.
Can a tornado hit Oman?
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.
If you were to take a picture of earth from space are you able to see weather systems such as midlatitude cyclones fronts tropical cyclones thunderstorms or tornadoes?
You can see systems such as mid latitude cyclones, fronts, and tropical cyclones as well as thunderstorms, though they are not considered their own weather systems. You cannot see tornadoes from space. Tornadoes descend from thunderstorms, which block the view from above. Also, tornadoes, like thunderstorms, are not weather systems, but simply weather events
Do cyclones have tornadoes in them?
Some cyclones produce tornadoes, but most do not.
Which is stronger tornadoes or cyclones?
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.
Do storms turn?
Some do. Tropical cyclones (hurricanes, typhoons etc.), extratropical cyclones/lows, Some thunderstorms (mostly supercells), and tornadoes are all storms that rotate.
Do tornadoes have real eyes?
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.
What are hurricanes and tornadoes called?
Tornadoes can be called twisters, but tornado is the preferred term. Hurricanes are also called tropical cyclones, though that is a somewhat broader term.
Why don't hurricanes or tornadoes enter the southern hemisphere?
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.
What are the destructive forms of cyclone?
The most destructive cyclones are tropical cyclones, which in various parts of the world are called hurricanes and typhoons. Extratropical cyclones can also be destructive by producing strong winds and flooding. Both can produce severe thunderstorms and tornadoes. Note that while tornadoes are destructive they technically are not cyclones even though they are often referred to as such.
Why are tornadoes not named?
They are not named like tropical cyclones because there is very little warning. The reason tropical cyclones are named is so people can follow them as they develop and move along, making each system easy to keep track of. Tornadoes form very quickly and without warning, and it would not make sense to try to apply a name to them. Additionally, while there are usually no more than a dozen named tropical cyclones in a year, Over 1,000 tornadoes hit the U.S. each year, far to many to be named.
How can you compare and contrast tornadoes hurricanes and cyclones?
Tornadoes are small, storm-scale vorticies which occur within thunderstorms, and extend downwards from the bases of strong, typically rotating storms. Most tornadoes are small, with a width of a few yards. However, larger, "wedge-shaped" tornadoes may be up to 4 miles in width, and cause the most damage.Cyclones are large, synoptic-scale rotational features, which rotate cyclonically. These include low-pressure systems. Nor'easters and tropical cyclones are cyclones.Hurricanes are a type of cyclone, and more specifically, a type of tropical cyclone. Tropical cyclones are what people usually refer to when they say 'cyclone' - a large, organized swirl of thunderstorms with strong winds. However, hurricanes are tropical cyclones that occur in the North Atlantic Ocean or Eastern Pacific Ocean. Broadly speaking, any tropical cyclone in these two regions may be called a hurricane. However, when meteorologists classify these storm systems, hurricanes are tropical cyclones in those basins with winds of over 75 mph.
