Tornadic Forms
Tornadoes can develop as the traditional funnel or like a skinny rope like form. Most look like a cloud spinning around, others may have multiple torndoes (vortices) traveling around the centre. Some may be invisible or look like dust. Sometimes the only way to know a tornado is there, is the debris on the ground. Here are types of tornadoes which can form: Supercell Tornadoes These tornadoes are the most violent. Most, if not all of the deadliest tornadoes form from a Supercell cloud. A supercell storm lasts for a long period of time which has a stream of spinning air moving upwards constantly. The supercell cloud can produce large hail and tornadoes, even though less than half of the supercell creates tornadoes. Supercells are most common in the middle of the United States. These storms need the correct atmospheric instability for it to form. Waterspout Waterspouts are less severe and cause less damage. They form over tropical ocean waters, hence then name 'waterspout'. This type of tornado usually lose momentum on land and disappear. |
Landspout
A landspout tornado is the land equivalent of a waterspout. It is generally thought to be weaker than an average supercell tornado, with the only difference between the 2 would be that the mesocyclone is already preformed when it emerges in landspouts. Gustnado This type of tornado is weak and does not last very long. They usually form in front of a thunderstorm, and appear as debris clouds or dust whirls. |
