What Do You Know About Tornadoes? Essay Example

A tornado is a spinning, spiral cloud that runs from a sky to the surface and has winds exceeding 300 mph. Tornado destruction tracks can be more than one mile broad and 50 miles long. It’s critical to be equipped for a tornado (Ready.gov). Tornado activity is best predicted by rotating thunderstorms. On radar, they are well-defined thunderstorms with hail, heavy winds, lightning, and flash floods (Weather Underground, Inc). When a warmer front collides with a cold front, thunderstorms form, eventually producing one or more tornadoes. Strong winds or cyclones typically travel from the southwest to the northeast, but they can occasionally travel in the other manner for a brief duration.

A tornado can even retrace its path if winds from the thunderstorm’s eye touch it. Funnel clouds usually disappear in just 10 minutes, and some only last a few seconds. In rare circumstances, cyclones can last for nearly an hour. A tornado may seem nearly grinning till sand and particles are allowed or a cloud formed privileged the funnel. Tornadoes are also most predominant laterally Tornado Alley, a level area of terrain that bounces from western Texas to the Canadian boundary (Dakota Edwards, SPC, Roger). This area is a tornado hotbed since the dehydrated northern air from Canada encounters the warm moist airflow from the Gulf of Mexico. Tornadoes are mostly occurred at mutual amid equally the times of 3 and 9 p.m., nevertheless they can raid at slightly any period (Missouri State) and in March and May in the southern positions and late June to August in the southernmost positions.

What research has already been done on tornadoes?

A tornado expert is a type of meteorologist who studies tornadoes. Unlike other weather forecasters, those who investigate tornadoes are primarily meteorological scientists. NSSL has developed a 3-D computer simulation of tornado-producing thunderstorms (Boyle, Alan, and Roach). This model investigates what causes a thunderstorm to generate a tornado and how the twister and thunderstorms act in different meteorological circumstances. According to Dr Jennifer Francis of the Woods Hole Research Center in Massachusetts, changes in Arctic sea ice have caused ridge structures in the airflow. While tornadoes become less and less common in the components that make up Tornado Alley, they are growing more common in other areas (Missouri State). The solid dispersion of supercell-tornado wind is documented in the Warman study, while the difference could be attributed to a lack of complete data.

The month with the highest tornadoes in March to May hardest hits the southern states. The process of random sampling, independence, large sample and 10% condition (Palm Beach County). Additionally, the success or failure of the state and the homogeneity of variance are also part of the assumption to be done. The sample size should be n in length, of which the individuals have to be chosen independently of one another, and they’re at least several successes and failures in the sample.

Since the population standard deviation is unpredictable in almost all circumstances in practice, it is sensible to employ the t-test for even large samples assuming all other variables have been evaluated. We interact with the t – statistic when using sample variance for random effects.
