In meteorology, a cyclone is an area of low atmospheric pressure characterised by inward spiraling winds that spin counterclockwise in the northern hemisphere of the Earth, and clockwise in the southern hemisphere.[1][2] Covering a wide variety of meteorological phenomenon such as tropical cyclones, extratropical cyclones and tornadoes, the generic term is rarely used by meteorologists without a qualifier.
A tornado is a violently rotating column of air which is in contact with both a cumulonimbus (or, in rare cases, cumulus) cloud base and the surface of the earth. Tornadoes can come in many shapes, but are typically in the form of a visible condensation funnel, with the narrow end touching the earth. Often, a cloud of debris encircles the lower portion of the funnel.
Most have winds of 110 mph (175 km/h) or less, are approximately 250 feet (75 meters) across, and travel a few miles (several kilometers) before dissipating. However, some tornadoes can have winds of more than 300 mph (480 km/h), be more than a mile (1.6 km) across, and stay on the ground for dozens of miles (more than 100 kilometers).[1][2][3]
They have been observed on every continent except Antarctica; however, a significant percentage of the world's tornadoes occur in the United States.[4] (approximately 75% of all that take place) This is mostly due to the unique geography of the country, which allows the conditions which breed strong, long-lived storms to occur many times a year. Other areas which commonly experience tornadoes include New Zealand, western and southeastern Australia, south-central Canada, northwestern Europe, Italy, south-central and eastern Asia, east-central South America, and Southern Africa.[5]

Yes I agree that these terms can be confusing. First off Hurricanes, Typhoons and Cyclones are all the same. They all come in from the sea and are powered by the warm waters, this is the reason why we don't get them in the UK. Hurricanes are what English people call them. Typhoons are Japanese and Cyclones are the other Asians. Tornadoes are completely different they come when hot air and cool air meet and puncture a layer above and then a tornado starts to appear and come out of the clouds and hits the Earth Please don't get mixed up between these two they are like opposites to each other.

Cyclone: Large scale weather system that spins counter-clockwise in the northern hemisphere. These are large low pressure systems with associated fronts. Example: When the weatherman on TV is talking about a storm system moving in from the west which may bring increasing clouds, rain and a front, that is a cyclone.
Tornado: A violently rotating column of air that extends from cloud base to the ground. Since the tornadoes are small scale areas of low pressue spinning counterclockwise, they have been referred to them as cyclones. Tornadoes can cause serious damage due to their violent winds. They are usually visible due to condensation (cloud or funnel) formed by low pressure. Other visible forms are from dust, dirt and debris. Tornadoes typically rotate counterclockwise in the northern hemisphere, but some rotate clockwise.

A cyclone in the northern hemisphere is associated with atmospheric low pressure region or air mass.
The cyclone winds spin around a common center
in the counter-clockwise direction. Tornadoes and hurricanes in the northern hemisphere are severe examples of cyclones.

If you live in the US, cyclone, twister, and tornado all mean the same thing, but in the Indian Ocean region a cyclone is a hurricane.

too many long answers, READ this.. it's short and informative: a cyclone is an area of low pressure (spins counter-clockwise) AND guess what, a tornado is a cyclone - bascially.......A tornado is violent windstorm, a cyclone is the thing you see on a weather map that has a big "L" (meaning low pressure) Hurricanes are also cyclones

A good site below...
Tornadoes occur over land and not over the sea such as a cyclone....
Hope this helps.
