A tropical cyclone is a storm system characterized by a low

pressure center and numerous thunderstorms that produce

strong winds and flooding rain. Tropical cyclones feed 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.

A tornado is a violent, 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.

Most tornadoes have wind speeds between 40 mph (64 km/h)

and 110 mph (177 km/h), 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).

A flood is an overflow of an expanse of water that submerges

land, a deluge. In the sense of "flowing water", the word may

also be applied to the inflow of the tide.

Flooding may result from the volume of water within a body of

water, such as a river or lake, exceeding the total capacity of its

bounds, with the result that some of the water flows or sits

outside of the normal perimeter of the body. It can also occur in

rivers, when the strength of the river is so high it flows right out

of the river channel, particularly at corners or meanders.
