The vast majority of tornadoes are cyclonic, though it would be incorrect to call them cyclones.
Anticyclonic tornadoes are rare, accounting for less than 1% of all tornadoes.
No, Streator, Illinois was hit by a tornado, which is different from a cyclone.
A cyclone is more closely related to a hurricane. A cyclone is a general term used to describe a rotating low-pressure weather system, which can develop into hurricanes, typhoons, or tropical cyclones depending on the region. Tornadoes, on the other hand, form in severe thunderstorms and are characterized by a twisting, funnel-shaped cloud extending from the sky to the ground.
A cyclone. Cyclones cover areas hundred of miles wide. Tornadoes more than a mile wide are rare.
A cyclone is virtually any low pressure system that rotates counterclockwise in the northern hemisphere or clockwise in the southern hemisphere. This would include ordinary low pressure systems which often bring rain and thunderstorms but are not necessarily severe. Tropical storms, tropical depressions, and hurricanes are also considered cyclones. Typhoons are cyclones in the western North Pacific. A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground. The vast majority of tornadoes are cyclonic but a small percentage are anticyclonic, meaning they spin clockwise in the northern hemisphere or counterclockwise in the southern hemisphere.
No. A tornado produces the steepest pressure gradient of any weather phenomenon. An intense mid-latitude cyclone might have an overall pressure deficit comparable to a weak tornado, but that pressure gradient is spread out over several hundred miles. A tornado produces at least that much of a pressure drop over only a few hundred feet.
A Bora is not a cyclone. Tornadoes more features in common with cyclones, but they are technically not cyclones either.
No, Streator, Illinois was hit by a tornado, which is different from a cyclone.
A cyclone is bigger than a tornado by far, but a tornado is usually more violent.
No country really calls a cyclone a tornado. Some parts of the U.S. a tornado a cyclone, though a tornado and a cyclone are two different things. In the U.S. however a strong tropical cyclone is called a hurricane.
No. Most homes do not. Tornado shelters are more common where tornadoes are more common.
That depends on where the tornado is. Generally, tornadoes in the northern hemisphere rotate counterclockwise while those in the southern hemisphere rotate clockwise. There are more violent tornadoes in the horthern hemisphere, but that is mostly due to the fact that portions of the United States have an almost perfect setup for producing them. A small percentage of tornadoes rotate in the opposite direction from what is normal. These are called anticyclonic tornadoes (normal tornadoes are cyclonic). Many anticyclonic tornadoes are satellite tornadoes, and are generally weaker than the parent tornado that spawned them. Only one anticyclonic tornado has ever recieved a violent (F4 or F5) rating on the Fujita scale. It was an F4 that hit West Bend, Wisconsin on April 4, 1981.
The duration of a cyclone or twister can vary widely depending on its size and intensity. On average, a cyclone or tornado typically lasts for a few minutes to a few hours, with the most powerful tornadoes potentially lasting up to an hour or more. Cyclones can last for several days as they move across a region.

No such tornado happened in 2008. The Daulatpur-Saturia tornado in Bangladesh did kill 1300 people, but it was in 1989. It is the only tornado to have killed more than 1000 people. One possible source of confusion is Cyclone Nargis, which struck Myanmar in 2008, killing 130,000. This however was not a tornado but was basically a hurricane.
Jupiter's Great Red Spot isn't really a tornado, and actually has more in common with a hurricane. But, to answer the question, it is over 300 years old, possibly much older. It has been raging since at least the first time Jupiter was observed through a telescope. It is not known how long it was going on before that.
