    A tornado is a small feature whose width is generally less than 1 kilometer.  In a tornado, very high speed winds (hundreds of miles per hour) create a centrifugal force that balances an intense pressure gradient force, as the pressure at the center of the tornado can be 900 mb or less, as compared with standard atmospheric pressure of 1013 mb.  The tornado travels along at 0 to 60 mph, but usually runs out of energy within an hour.  The initial source of a tornado is usually a thunderstorm with a rotating "supercell" at an altitude of several miles, and the tornado is fed by warm air rising from the ground if and when the center of the cell begins to sink.  However the "rear flank downdraft" then chokes off the warm air supply, killing the tornado quickly.

    A tropical cyclone is a large feature, often hundreds of km in width.  Here again the minimum pressure may be 900 mb or less, but the pressure gradient is lower than that in a tornado, as the difference in pressure is more gradual.  The inward force created by the pressure difference is balanced not only by the centrifugal force of high winds but also by the Coriolis force, which affects any large-scale atmospheric motion that is not precisely equatorial.  Hence, the centrifugal force of hurricane winds is less than that of a tornado, i.e., the wind speeds are lower.  Sustained winds of 200 mph are possible but unusual; that's why a "category 5" hurricane, the most intense, includes all storms whose winds are over 155 mph.  The hurricane or cyclone typically lasts for many days, as it continues to pick up energy while it is traveling over warm water, and the total length of the cyclone's path can be thousands of miles.

    Tropical Cyclones is really just a more clinical term for a hurricane or a typhoon, depending on where you are the term is used differently!

    A tropical cyclone is a rapidly rotating storm that forms in oceanic waters of at least 26C or warmer! Hurricanes tend to strengthen rapidly over warm waters, but quickly weaken once the eye wall makes landfall (usually within 12 to 24 hours of landfall). Hurricanes tend to produce a lot of rain (sometimes feet worth), high winds (up to 350 km an hour) and often times will produce weak tornadoes (landspouts). A hurricane's destruction path is wide, and long, ranging many km's to several 1000, depending on the track and size of the storm.

    A tornado is formed one of two ways 1) In a super cell storm 2) rotation with windsheer in the upper atmosphere. Tornadoes are formed when there is a 3 way mix of warm air at the surface, humid air in the middle and cold air towards the top of a cloud base! A tornado is basically a lowering of a cumulus cloud, its a funnel from the base, but once it touches ground it becomes a tornado. Tornadoes can have winds anywhere from 100-400km an hour, depending on the type of storm! They tend to be very short lived, often on the ground for no more than several minutes, and their path of destruction tends to be very narrow in terms of length and width, anywhere from meteres to maybe several km's. 

    So to do a chart here

    Hurricanes:                                                                        Tornadoes

    - Formed over ocean                                                        - Usually formed over land

    - Path of destruction is long and wide                           - Path of destruction is short 

    - Lots of rainfall                                                                 - No rainfall occurs

    - Classified as Categories                                              - Classified as E0's- EFs

    - Large and wide                                                              - Long and narrow from the sky

    - Is a storm                                                                         - Formed as part of a storm

    - Born over warm waters                                                 - Born from a cumulus cloud

    A cyclone is a large, destructive storm that is comprised of strong winds rotating around a center of low pressure. Depending on the region, a cyclone may be referred to as a typhoon or hurricane. ... A tornado is a violent storm comprised of extremely strong winds spiraling around a central point in a funnel-shaped cloud.
