Get the facts right. Determine the difference between these 3 terms and here’s the answer.
A hurricane is a tropical cyclone. Simply put:
Hurricane = Cyclone
What is a Hurricane = Cyclone
A tropical cyclone is a storm system characterized by a low pressure center and numerous thunderstorms that produce strong winds and flooding rain. A tropical cyclone feeds on heat released when moist air rises, resulting in condensation of water vapour contained in the moist air. They are fueled by a different heat mechanism than other cyclonic windstorms such as nor’easters, European windstorms, and polar lows, leading to their classification as “warm core” storm systems.
What is a tornado
A tornado is a violently rotating column of air which is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. 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.
Differences Between Tornado and Cyclone
|Size||Has a diameter on the scale of hundreds of meters||Has a diameter on the scale of hundreds of kilometers|
|How are they formed||Produced from a single convective storm (i.e. a thunderstorm or cumulonimbus cloud)||Comprised of several to dozens of convective storms|
|Required Condition||require substantial vertical shear of the horizontal winds to provide ideal conditions for tornado genesis, and usua;;y happens in regions of large temperature gradient||Require very low values of tropospheric vertical shear in order to form and grow, and generated in regions of near zero horizontal temperature gradient|
|Appears on||Primarily an over-land phenomenon, as solar heating of the land surface usually contributes toward the development of the thunderstorm that spawns the vortex, although over-water tornadoes have occurred||Purely an oceanic phenomena. They die out over land due to a loss of a moisture source|
|Lifetime||Usually dies out in minutes||Can last for a few days|
