Tornado Essay -- Natural Disasters Weather

A tornado is defined as a violently rotating column extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of two hundred and fifty miles per hour or more. Damage paths can be more than one mile wide and fifty miles long. In an average year, eight hundred tornadoes are reported nationwide, resulting in eighty deaths and over one thousand five hundred injuries. In the body of my essay, I will tell you about types of tornadoes, where tornadoes come from, where and when tornadoes occur, the damage they inflict, variations of tornadoes, and how to detect tornadoes. There are many types of tornadoes. The average tornado is usually split up into categories based on the strength of the tornado. Most tornadoes, about sixty nine percent 69%, are considered weak, which means they usually last between one minute and ten minutes, have winds less than one hundred and ten miles per hour, and the percent of deaths that occur during these is less than five percent. Strong tornadoes, about twenty nine percent 29%, may last about twenty minutes, have winds between one hundred and ten and two hundred and five miles per hour, and the percent of deaths that are found are about thirty percent of all tornado deaths. The last category for tornadoes is violent ones. With these comes winds greater than two hundred and five miles per hour, they can last about an hour, and have seventy percent of all deaths from tornadoes. Another type of tornado is known as a waterspout. This is a weak tornado that forms over warm water. They are most common along the Gulf Coast and southeastern states. In the western United States, they occur with cold late fall or late winter storms, during a time when you least expect it to develop. They occasionally move inland becoming tornadoes that can cause a great deal of damage and many injuries. Most tornadoes evolve from energy. Tornadoes come from the energy released in a thunderstorm. As powerful as they are, tornadoes account for only a tiny fraction of the energy in a thunderstorm. What makes them dangerous is that their energy is concentrated in a small area, perhaps only a hundred yards across. Not all tornadoes are the same, of course, and science does not yet completely understand how part of a thunderstorm's energy sometimes gets focused into something as small as a tornad... ...ms using all the information they can obtain from weather maps, modern weather radar’s, storm spotters, monitoring power line breaks, and so on. These are all important tornado facts and reasons of why this phenomenon occurs. Tornadoes are natural disasters that we can not do anything about, we just have to learn to live with them and be smart about how we approach them. There is no preventing a tornado from occurring so we must merely take all the precautions so we will be safe.
