The term cyclone is used as a scientific labeling for, "cyclones", hurricanes & typhoons. They are the same deal a huge twister - a weather system, namely a storm system - which evolve usually from the oceans, it's a typhoon if you're on/around Asia and the Pacific Ocean, a Hurricane if your in Texas or on the Atlantic, and a cyclone if your eating curry aroud the Indian Ocean.
Tornadoes are the twisters that usually begin on land and are an effect of a weather system, there can be simultaneous occurrences of tornadoes, whereas typhoons usually only have one eye or twister.
Nasa says, Meteorologists classify weather systems according to their size and how long they last. The two largest and longest-lasting types of systems are planetary-scale systems and synoptic-scale systems. Planetary-scale systems are the belts of winds that circle the globe and may blow in the same direction for weeks at a time. Synoptic-scale systems cover a portion of a continent or ocean and last up to a week or so. The term synoptic comes from a Greek word meaning a general view.
A supercell thunderstorm is a violent storm dominated by a single gigantic cell -- a weather system made up of storm clouds and the winds associated with them. Rain and hail may fall for hours.

Two briefer and smaller types of systems are mesoscale systems and microscale systems. Mesoscale systems may last an hour or less and are so small they may affect the weather of only part of a city. Examples include thunderstorms and sea breezes. Microscale systems, such as tornadoes, usually last only several minutes and affect an area not much larger than a few football fields.
