What Are The Different Types of Tornadoes?

        Let's state the types of tornadoes to start with: a supercell torando, a landspout, a gustnado, a waterspout, and dust devils. Now that you know the types maybe we should dig a little deeper and figure out what these tornadoes are like. First we can start on the supercell tornadoes. Supercell tornadoes are formed from continuous thunderstorms that have a consistent rotating updraft of air. Supercell tornadoes are most commonly known to have a wedge-like shape that makes the tornado look very large. A supercell thunderstorm has a low-hanging rotating cloud called a "wall cloud". The wall clouds have a dangerous looking shape that really just hangs over an area. Wall clouds will sometimes have areas that will pour rain while the other areas don't have rain at all. Wall clouds overall are just really unpredictable because they might just produce a supercell tornado. Supercell tornadoes are the most violent tornadoes because they have the longest touchdown period( maybe and hour or more) and the have the most frightening wind speeds that reach higher than 200 mph.
         A landspout tornado  is generally weaker than a supercell tornado, a landspout does not form with a wall cloud. It may be be seen beneath towering clouds and is the land version of a waterspout. It often forms along the leading edge of the rain-cooled downdraft air coming from a thunderstorm, known as a “gust front."
         A gustnado is usually weak and mostly short-lived. A gustnado usually forms along the "gust front" of a thunderstorm and looks more like a dust whirl or a debris cloud. In these tornadoes it may not appear to be twirling or twisting in any form. These appear like dust devils, just out of the blue.
           A waterspout is a different type of tornado. Even though most people think that it is impossible for tornadoes to form over water I am here to tell you that it is very possible. A few form from supercell thunderstorms, but many form from weak thunderstorms or rapidly growing cumulus clouds. Waterspouts are usually less intense and causes far less damage. They are no more than fifty yards wide, they forms over warm tropical ocean waters, its funnel is made of freshwater droplets condensed from water vapor- not saltwater from the ocean. Waterspouts usually dissipate upon reaching land.
           The last type of tornado we will talk about is called a dust devil. Dry, hot days can bring about a dust devil. Dust devils form because a light breaaze keeps building and causes a swirling pattern. Dust devils are not very violent but they are known to cause minor damage, like blowing cars off the rode and getting dust in your eyes. Dust devils are called cousins of the tornado because the swirl but they do not form in storms like tornadoes do.
