Enhanced Fujita Scale

According to Enhanced Fujita Scale, the tornadoes in the United States and Canada can be rated in six categories: EF0, EF1, EF2, EF3, EF4 and EF5. Scale Wind speed (mph) Rating classifications EF0 65–85 Weak EF1 86–110 Weak EF2 111–135 Strong and significant EF3 136–165 Strong, significant and intense EF4 166–200 Violent, significant and intense EF5 >200 Violent, significant and intense Figure 1. The six categories of tornadoes of the Enhanced Fujita Scale EF5 tornadoes have happened in the Unites States, which are nines in Kansas, Mississippi, Iowa, Alabama, Missouri and Oklahoma. Some tornadoes can look the same but they do not cause the same damages even though the weakest tornadoes may kill. Examples of this fact is the report of tornadoes between 1997 and 2005 which states 3 people were killed by F0 tornadoes and 38 by F1 tornadoes in the United States. F0 tornadoes cause superficially damages to structures and the environment. The conventional building cannot be damage too much if the building is well constructed. This building…

Introduction Rotating funnel-shaped clouds that can leave a mile wide damage path that can grow to fifty miles long (Tornado Facts and History). From May to early June, warnings and watches are put out to protect people from these powerful forces of nature. Understanding how they form and what to look for before one touches down can save the lives of many people. Looking into history, past tragic events can help future ones to be less tragic. The scale rating these tornadoes can show just how…

tornado, dark, funnel-shaped cloud containing violently rotating air that develops below a heavy cumulonimbus cloud mass and extends toward the earth. The funnel twists about, rises and falls, and where it reaches the earth causes great destruction. The diameter of a tornado varies from a few feet to a mile; the rotating winds may attain velocities of 200 to 300 mi (320–480 km) per hr, and the updraft at the center may reach 200 mi per hr. The Enhanced Fujita scale is the standard scale for…

peace was ripped away from their souls. May 22, 2011 will forever have a hold of the hearts of many Missourians in Joplin. The 2011 Joplin tornado was a catastrophic EF5 multiple-vortex tornado that struck Joplin, Missouri in the late afternoon of Sunday, May 22, 2011. “The Enhanced F-scale, or EF scale, is a set of wind estimates (not measurements) based on damage” (Enhanced Fujita Tornado Damage Scale). The Joplin tornado reached wind speeds of at least 200 mph, putting the tornado at the…

These power lines not only posed danger to anyone that came near them but also house chemicals. Power lines include transformers and different electrical components that can contain oils that can be highly toxic. Many of the companies in the town housed chemicals for industrial operations and plants that were also spread throughout the town. Damages, Injuries and Fatalities The Fujita scale is how tornadoes are rated. This rating is based on wind speeds which cannot actually be accurately…

For my essay, I am going to write about tornadoes. My question is how do storm chasers measure the speed of a tornado? The first topic I will be telling you about is the F scale. Did you know the person who invented the F scale went to the University of Chicago. The second topic is about tornadoes and about 1,200 tornadoes hit the U.S. each year. My final topic is over storm chasers. I learned that storm chasers park southeast of the tornado because usually it is the safest place to park. There…

speed and intensity, which would be about an EF4 to an EF5, kind of like the wedge, but the wedge is much more stronger. "Gigantic, roaring masses of fury that can grow one mile wide or even larger (Mersereau 115)." Being a mile wide is a huge base of a tornado, they can get even bigger the that. With being this big they can do a ton of damage to a city or even a field of crop by a farm. Even though it is the second most dangerous tornado that can happen, it still have just the same…

They begin as tropical depressions; when surface-wind speeds exceed 39 mph, they become tropical storms (Abbott, 2012). Once wind speeds reach 74 mph, the tropical storm becomes a hurricane. At this point, a distinctive “eye” forms in the middle of the storm. However, hurricanes are not uniform—rather, each hurricane is a collection of individual storms. Hurricane season runs from June to November, but most occur between August and October (“Hurricanes,” 2013). Each hurricane is ranked on the…

In April of 2011, a supercell caused 363 tornadoes to touch down in several states within a four day period. On April 27th alone, the National Oceanographic and Atmospheric Administration confirmed over 200 tornadoes touched down that ranked between F-0 and F-6 on the Fujita scale. This record breaking phenomenon resulted in the deaths of 348 people with damages estimating over $11 billion dollars. Due to the magnitude of the outbreak, National Weather Services assigned several teams to not only…

Tornadoes come from two types of thunderstorms called supercell and non-supercell. Tornadoes that come from a supercell thunderstorm are the most common, and often the most dangerous. Supercell thunderstorms form when there is a rotating updraft. “Only about 20% of all supercell thunderstorms, will actually produce a tornado” (Tornado Types). The other one is non-supercell thunderstorms. Non-supercell thunderstorms are circulations that do not form from an organized storm-scale rotation. These…
