1974 Xenia Tornado
On April 3, 1974, a tornado struck Xenia and Wilberforce, Ohio, killing 36 people. It is the deadliest individual tornado of the 1974 Super Outbreak. The tornado destroyed a large portion of Xenia, which caused meteorologist Dr. Ted Fujita to initially assign a preliminary rating of F6 intensity of ± 1 on the Fujita scale, making it the second tornado to receive this rating, the first being the 1970 Lubbock tornado. However, the rating was later downgraded to F5 after Fujita deemed F6 ratings "inconceivable". Meteorological synopsis A powerful springtime low pressure system developed across the North American Interior Plains on April 1. While moving into the Mississippi and Ohio Valley areas, a surge of moist air intensified the storm. There were sharp temperature contrasts between both sides of the system. Officials at NOAA and in the National Weather Service forecast offices were expecting a severe weather outbreak on April 3, but not to the extent that ultimately occurred. ...

Eastern Time Zone
The Eastern Time Zone (ET) is a time zone encompassing part or all of 23 states in the eastern part of the United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama, Colombia, mainland Ecuador, Peru, and a small portion of westernmost Brazil in South America, along with certain Caribbean and Atlantic islands. Places that use: * Eastern Standard Time (EST), when observing standard time (autumn/winter), are five hours behind Coordinated Universal Time ( UTC−05:00). * Eastern Daylight Time (EDT), when observing daylight saving time (spring/summer), are four hours behind Coordinated Universal Time ( UTC−04:00). On the second Sunday in March, at 2:00 a.m. EST, clocks are advanced to 3:00 a.m. EDT leaving a one-hour "gap". On the first Sunday in November, at 2:00 a.m. EDT, clocks are moved back to 1:00 a.m. EST, thus "duplicating" one hour. Southern parts of the zone (Panama and the Caribbean) do not observe daylight saving time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The 1974 Xenia Tornado On Radar
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

Hook Echo
A hook echo is a pendant or hook-shaped weather radar signature as part of some supercell thunderstorms. It is found in the lower portions of a storm as air and precipitation flow into a mesocyclone, resulting in a curved feature of reflectivity. The echo is produced by rain, hail, or even debris being wrapped around the supercell. It is one of the classic hallmarks of tornado-producing supercells. The National Weather Service may consider the presence of a hook echo coinciding with a tornado vortex signature as sufficient to justify issuing a tornado warning. History Because of the unpredictable and potentially catastrophic nature of tornadoes, the possibility of detecting tornadoes via radar was discussed in the meteorological community in the earliest days of meteorological radar.Huff, F.A., H.W. Hiser, and S.G. Bigler, 1954Study of an Illinois tornado using radar, synoptic weather and field survey data Report of Investigation 22, Champaign, IL, pp. 73 The first association bet ...

Multiple Vortex Tornado
A multiple-vortex tornado is a tornado that contains several vortices (called subvortices or suction vortices) revolving around, ''inside'' of, and as part of the main vortex. The only times multiple vortices may be visible are when the tornado is first forming or when condensation and debris are balanced such that subvortices are apparent without being obscured. They can add over 100 mph to the ground-relative wind in a tornado circulation and are responsible for most cases where narrow arcs of extreme destruction lie right next to weak damage within tornado paths. General Suction vortices (or suction spots) are really substructures of many, perhaps all, tornadoes but are not always easily visible. These usually occur at the base of the tornado vortex where the tornado makes contact with the surface. Subvortices tend to form after vortex breakdown reaches the surface and are resultant from the ratio of cyclonically incoming and rising air motions. Multivortex structure is ...

Bellbrook, Ohio
Bellbrook is a city in Greene County, Ohio, United States. The population was 7,317 at the 2020 census. It is part of the Dayton Metropolitan Statistical Area. It sits about 20.5 miles, ( 17km) south east from central Dayton. History Bellbrook was laid out in 1816. The name Bellbrook is an amalgamation of the name one of the city's founders, Stephen Bell, and Little Sugar Creek. A post office called Bell Brook was established in 1817, and the name was changed to Bellbrook in 1895. Initially a village, Bellbrook grew by way of annexation of territory from surrounding Sugarcreek Township. The first annexation, in 1970, helped push the population over 5,000 and led to Bellbrook achieving city status in 1974. With large amounts of build-able land, the area added over 1,000 housing units since the annexation. Today the city is largely developed with little land left for future development. Most of the development is taking place in neighboring Sugarcreek Twp. Geography Accordin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Midwest
The Upper Midwest is a region in the northern portion of the U.S. Census Bureau's Midwestern United States. It is largely a sub-region of the Midwest. Although the exact boundaries are not uniformly agreed-upon, the region is defined as referring to the states of Michigan, Minnesota and Wisconsin; some definitions include Iowa, North Dakota and South Dakota as well. Definitions The National Weather Service defines its Upper Midwest as the states of Iowa, Michigan, Minnesota, North Dakota, South Dakota and Wisconsin. The United States Geological Survey uses two different Upper Midwest regions: *The USGS Upper Midwest Environmental Sciences Center considers it to be the six states of Illinois, Indiana, Iowa, Michigan, Minnesota and Wisconsin, which comprise the watersheds of the Upper Mississippi River and upper Great Lakes. *The USGS Mineral Resources Program considers the area to contain Illinois, Indiana, Michigan, Minnesota and Wisconsin.
