¶ … formation of a tornado; the composition, causes, kinds and magnitude of destruction this natural calamity is capable to bring about. Tornado, a mysterious and violently destructive windstorm, is a funnel-shaped cloud extending towards the ground with a dark cumulonimbus mass on its end facing the ground. The funnel twists about into a mad oscillation of 200-300 miles per hour and is capable of causing great destruction where it meets civilization. This paper unlocks the mysteries of how a tornado is formed and unveils a violent aspect of Mother Nature.
TORNADO
Before we can understand how a tornado is formed, it is important that we discover and visualize the structure and mechanism of such a gigantic body. A tornado is a rotating column of air with a width of a few yards to more than a mile which spins at destructive high speeds accompanied by a conical downward extension of a cumulonimbus mass of cloud. A cumulonimbus cloud is a massively dense, vertically developed accumulation with a faintly hazy outline extending great heights. It usually produces heavy rains, thunderstorms, or hailstorms. The diameter of a tornado varies between a few feet to a mile. The range of a tornado can extend from less than a mile to several hundred miles. Its direction is dependent upon that of the prevailing wind. Generally, tornadoes travel in a northeast direction at a speed ranging 20-60 m.p.h. The scale that measures the severity of a tornado is called the Fujita Scale. The Fujita or F-scale measures the severity of a tornado by the damage it causes. Wurman, a meteorologist of high stature, has constructed a mobile radio weather forecaster known as Doppler on wheels to study tornadoes more closely, his research and efforts will help in providing better forecasts of tornadoes. "Warnings usually only happen with a few minutes of lead time," he says. "In...
TORNADOES What causes a tornado? Tornado' comes in English from a Spanish word 'tornada' that means 'thunderstorm'. As defined by Nation Weather Service, a tornado is a 'violently rotating column of air in contact with the ground and pendant from a thunderstorm'. Tornadoes result when there is stuffiest amount of moisture in the atmosphere at lower and mid levels, and when this condition gets combined with warm unstable air that rises above
Seconds later the twister struck. The kitchen door fell on the husband, pinning him to the ground. After the roof blew away, hail battered his face and body. The house disintegrated, but he survived and so did the dog. The woman, however, was crushed in the debris (Rosenfeld 179). By coincidence, researchers from the University of Oklahoma were just outside Spencer before the tornado hit, which is one reason authors
Tornadoes in the United States Every state in the union has experienced them, and the destruction caused by tornadoes each year can climb into the billions of dollars. Scientists have learned a great deal about tornadoes over the past several decades, though, and warning systems are now able to prevent many of the casualties that tornadoes used to cause. To determine what has been learned and what steps have been taken
convert it into "Green Town" Overall Analysis of the Rebuilding Process The region of Greensburg is an agricultural community, which is located in south-central Kansas. The day of May 4, 2007, marked a great tragedy in Greensburg, when it witnessed an EF-5 tornado. The study by FEMA (2007) states that according to the standard meteorological scale this was the most severe tornado in terms of wind speed. The consequence of the
Interagency Cooperation of Incident ManagementSevere Tornado Outbreak in the Southern United States, April 2011Brief DescriptionOn 27-28th April 2011, America witnessed its severest tornado outbreak since the year 1974. The month became one among the most devastating, active, and fatal tornado months recorded for the nation, serving as a potential benchmark for future months. SPC (Storm Prediction Center) information reveals a total of 875 preliminary tornadoes were reported in that month,
Geology (1) Discuss which of the interrelationships between the environmental spheres, in your experience, has had the biggest effect on human society, or vice versa. Give some examples. The work of Manahan (2005) explains that there are four traditional environmental spheres including the hydrosphere, atmosphere, geosphere and the biosphere. It is related however, that a fifth sphere should be included and that is the anthrosphere, which consists of "the things humans make
