Phenomenons that occur most frequently are thunderstorms, tsunami, and earthquakes. Here, two of the very common thunderstorms are distinguished, i. Funnel Cloud and Tornado. The difference between Funnel clouds and Tornadoes is that they vary in density. Funnel clouds are denser and form a distinctive funnel-like shape, thus named so. Tornado, on the other hand, is lighter and looks like a fast-running vortex. Funnel clouds barely touch the surface of the ground, and when they do, they convert themselves into a tornado.
Funnel cloud gets the name from its shape. Funnel clouds are funnel-shaped vortexes of heavy water vapours with air spinning at higher speeds. Funnel clouds can form under the rain clouds if it has sufficient vorticity and humidity in the air. There are two types of funnel clouds, namely landspouts and waterspouts, which can reach the ground but are usually weak to cause any harm.
A tornado is a sharp rotating column of air that can reach the ground. There is no need to resubmit your comment. Notify me of followup comments via e-mail. Written by : Mabelle. User assumes all risk of use, damage, or injury.

Waterspouts occasionally move inland, as soon as the base of the rotating column of air moves over land the waterspout becomes a tornado. How strong are tornadoes? In , a tornado in Minnesota lifted an ton railroad train with passengers and carried it more than 80 feet. A tornado in Oklahoma once carried a motel sign 30 miles and dropped it in Arkansas.
In a Mississippi tornado carried a home freezer more than one mile. How big are tornadoes? Most tornadoes are on the ground 10 minutes or less, but in a tornado traveled miles across Missouri, Illinois, and Indiana in 4 hours. How fast can tornadoes move? The average speed of a tornado is around 35 miles an hour, but they can remain almost stationary or move as fast as 70 miles an hour.
The average tornado moves from southwest to northeast, but they can move in any direction and even change direction. The National Oceanic and Atmospheric Administration NOAA said a funnel cloud is a rotating column of air that extends from a base of a cloud, but never makes contact with the ground. If that funnel cloud makes contact with the ground or has a debris cloud or dust whirl beneath it, then it's classified as a tornado, which can create damage, according to NOAA.
Thunderstorms could produce several funnel clouds, but never a tornado as long as what forms doesn't touch the ground.
