Please help. Compare and contrast tornadoes and hurricanes

Best answer:

Answer by Katisha44
tornados are mini hurricanes, hurricanes have just progressed longer and have sucked up more hot hair and have become a LOOOT deadlier. =)

    While both tropical cyclones and tornadoes are atmospheric vortices, they have little in common. Tornadoes have diameters on the scale of 100s of meters and are produced from a single convective storm (i.e. a thunderstorm or cumulonimbus). A tropical cyclone, however, has a diameter on the scale of 100s of kilometers and is comprised of several to dozens of convective storms. Additionally, while tornadoes require substantial vertical shear of the horizontal winds (i.e. change of wind speed and/or direction with height) to provide ideal conditions for tornado genesis, tropical cyclones require very low values (less than 10 m/s [20 kt, 23 mph]) of tropospheric vertical shear in order to form and grow. These vertical shear values are indicative of the horizontal temperature fields for each phenomenon: tornadoes are produced in regions of large temperature gradient, while tropical cyclones are generated in regions of near zero horizontal temperature gradient. Tornadoes are primarily an over-land phenomena as solar heating of the land surface usually contributes toward the development of the thunderstorm that spawns the vortex (though over-water tornadoes, or waterspouts do occurr). In contrast, tropical cyclones are purely an oceanic phenomena – they die over land due to the loss of a moisture source. Lastly, tropical cyclones have a lifetime that is measured in days, while tornadoes typically last on the scale of minutes. For more information on tornadoes you can go to the Storm Prediction Center’s FAQ maintained by Roger Edwards. Tropical cyclones at landfall often provide the conditions necessary for tornado formation. As the tropical cyclone makes landfall and begins decaying, the winds at the surface die off quicker than the winds at, say, 850 mb. This sets up a fairly strong vertical wind shear that allows for the development of tornadoes, especially on the tropical cyclone’s right side (with respect to the forward motion of the tropical cyclone). For the southern hemisphere, this would be a concern on the tropical cyclone’s left side – due to the reverse spin of southern hemisphere storms.

    hope this helps
    good luck…

    hurricane is like a massive powerful storm but a tornado is like concentrated swirling air and it lasts less time but it cause more damage t wt it touches than a hurricane i dont want to see one i think id freak out

    the best way to figure out the difference is that hurricanes come from the water (oceans, not lakes) and tornadoes come from thunderstorms on land.
