A cyclone is a tropical revolving storm which forms over oceans.A tornado is a violently rotating column of air forming over the land(tornados forming over sea are called waterspout).Cyclone is a large scale system covering hundreds of miles whereas the tornado is a small scale system covering a few miles only.Cyclone lasts for many days whereas tornado lasts for a few hours only.The tornado has a funnel shaped cloud hanging from the base and usually touching the ground which is absent in the case of cyclones.
The whirling wind speed of the tornado will be sometimes more than that of the cyclone.

Cyclone
In meteorology, a cyclone is an area of low atmospheric pressure characterized by inward spiraling winds that rotate counter clockwise in the northern hemisphere and clockwise in the southern hemisphere of the Earth. In the Atlantic and eastern Pacific, including the Hawaiian islands, they are called hurricanes, in the western Pacific they are called typhoons and in the southern Pacific and the Indian Ocean they are called cyclones. Since the generic term covers a wide variety of meteorological phenomena, such as tropical cyclones, extratropical cyclones, and tornadoes, meteorologists rarely use it without additional qualification.
Tornado
A tornado is a violently rotating column of air which is in contact with both a cumulonimbus cloud or, in rare cases, a cumulus cloud base and the surface of the earth. Tornadoes come in many sizes but are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris.
Most tornadoes have wind speeds of 110 mph (177 km/h) or less, are approximately 250 feet (75 m) across, and travel a few miles (several kilometers) before dissipating. Some attain wind speeds of more than 300 mph (480 km/h), stretch more than a mile (1.6 km) across, and stay on the ground for dozens of miles (more than 100 km).
Although tornadoes have been observed on every continent except Antarctica, most occur in the United States.They also commonly occur in southern Canada, south-central and eastern Asia, east-central South America, Southern Africa, northwestern and central Europe, Italy, western and southeastern Australia, and New Zealand.

A CYCLONE IS A HURRICANE IN A DIFFERENT PART OF THE WORLD. IT IS THE EXACT SAME AS A HURRICANE, JUST THE PEOPLE CALL IT SOMETHING ELSE OVER THERE. A TORNADO IS A TWISTER THAT FORMS ON LAND. IN THE U.S., WE CALL A CYCLONE, A HURRICANE.

the latter is a subset of the former. All tornadoes are cyclones, not all cyclones are tornadoes.
