What is the name of three types of tornado?

Answer 1

Supercell Tornadoes

This type of tornado originates from supercell thunderstorms. The main characteristic of these storms is the presence of a thick upwardly drawn air current in a constant rotational motion, which is called mesocyclone. The tornadoes that are evolved out of these storms are big in size and are in the shape of a wedge. Supercell tornadoes tends to keep contact with the ground for a very long time and are extremely fierce in nature, with winds blowing at a speed above 200 mph.

Waterspout

This type of tornado is formed above the surface of water. There are two types of waterspout tornadoes - tornadic and non-tornadic or fair-weather. Tornadic waterspouts are mesocyclonic tornadoes that are formed over the surface of water. Since they are developed from thunderstorms, they possess high speed and intensity, and are terribly destructive in nature. On the other hand, fair-weather waterspouts are far less destructive. They are not a very strong kind of tornado. Their winds are weak in nature and move quite slowly. The intensity of a non-tornadic waterspout is weakened further when it reaches the land surface.

Landspout

The other name of landspout tornado is dust-tube tornado. This type of tornado is of much lesser intensity as compared to a supercell tornado and they are of shorter duration. It does not have any kind of association with mesocyclone. Even though it is a weaker form of tornado, it yields quite strong winds that are capable of inflicting massive damage. Usually, the smooth condensation funnel of landspout is not in touch with the ground. However, when it makes contact, a thin layer cloud of dust is formed. They form by essentially the same process as non-tornadic waterspouts.

Gustnado

A gustnado can be defined as a gust front tornado. It is a weak tornado that do not last for a long period of time. Technically, there is no link between the cloud base and the circulation of the wind. Hence, it is not considered as a tornado. It is a temporary whirl of dust and debris, confined to a small area with a heavy rotational wind. They look similar to dust devils.

Answer 2

Three types of tornado are: supercell tornadoes, which form within supercell thunderstorms; multiple-vortex tornadoes, characterized by smaller subvortices rotating around a common center; and waterspouts, tornadoes that form over bodies of water.
