Steps How Tornadoes Form
A tornado is a violent cloud that goes in a circular manner as it touches the ground, as it collects dust, debris and other earthly objects that it can carry.
As the tornado starts to form a funnel-shaped wall cloud that descend on the ground as it collects dust and debris and possible, other objects it comes across. This cloud may come in different colors particularly in a bluish-gray hue, depending on the amount of moist and the location. As a whole, the tornado becomes more visible when there is sufficient moisture and when the wall cloud touches the ground. One can see a tornado forming on the ground as dirt and debris whirls around and eventually moves with the storm. This is when the maturity starts and from there it remains stable until it becomes severe. The more severe a tornado goes, the more it becomes wider. Large tornadoes usually appear wider when the funnel decreases towards the ground.
The tornado shows its direction once it moves with the storm and the base tilts away from the wall clouds or from the ground it descends. It is difficult though, to determine the direction of the tornado if it is not visible so it its determined only by the observation at the wall cloud and the base.
The most dangerous and last stage of the formation of a tornado is the “rope” stage, so named because it appears like a rope. Although this is the weaker stage of a tornado, it is also the most unstable and still the most dangerous. Since it is unstable, it is difficult to determine its path too.
Because tornadoes have a variety of its severity, a scale that measures them was invented and called the Fujita scale. It measures the tornado from F0, where it is the weakest and F6, the strongest in terms the damage it may inflict. Although no tornado has reached F6, the strongest damage that has occurred was F5 which has been observed in the US. As F5 intensity has measured, it was tracked at 22 kilometers long and reached up to 1.6 km in width.
Since tornadoes are known to be one of the most dangerous natural calamities, it is always necessary to take special precautions whenever it is sited in a location. Most people who live in areas where tornadoes occur on quite a regular basis have underground rooms in their homes where they can run for safety during these times.
