    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…

    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.

    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…

    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…
