Tornadoes are still one of meteorology’s most mysterious phenomenon. Scientists are still unsure what conditions are necessary in order to create tornadoes, but some theories share similarities. Tornadoes need warm, moist air and cold, dry air in order to form super-cells. These super-cell thunderstorms can reach nearly 50,000 feet in height. A tornado forms when a a column of air begins spinning rapidly in a horizontal fashion. A powerful gust of wind or updraft, then takes that surface column of air and begins to turn it in a vertical position. The intense column of wind is then surrounded by clouds from the super-cell and lowers to the ground due to the influence of rain and hail. A tornado is only created when that column of air finally hits the ground and spawns one of natures most intense, destructive storms.
