Western Wisconsin Derecho
The Western Wisconsin Derecho was a derecho, or severe weather system, that occurred through several counties of Western Wisconsin on July 15, 1980. It caused $240 million in damage (equivalent to $ million in ) -- the largest storm damage total in Wisconsin history to that point. Three people died. The storm is still referred to as The July 15th Storm, July 15th, 1980, or simply The Storm. Prelude The storm developed during the devastating heat wave of 1980. Eight of the previous nine days in the Twin Cities had highs above . The high on July 11, 1980 was . On July 14, 1980, the day before the storm, the high was ; the overnight low was a sticky . The storm At 2 p.m. on the afternoon of July 15, 1980, a weak area of low pressure was stationed over eastern South Dakota, adjacent to a warm front that extended southeast through southern Minnesota into eastern Iowa. Ahead (north) of the warm front was an area of hot, dry air: the high temperature for the day at Eau Clai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Downsville, WI
Downsville is an unincorporated census-designated place in the town of Dunn, in Dunn County, Wisconsin, United States, where Highway 25 crosses the Red Cedar River. As of the 2010 census, its population was 146. The community was founded in 1855. Around that time, Ebenezer Thompson tried to dam the Red Cedar, but his half-built dam was destroyed by a flood. In 1857 Captain Downs tried again and succeeded in building a dam which powered a sawmill A sawmill (saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensi .... The village was platted in 1859, and named for Downs. He sold the mill to Knapp, Stout & Co., who expanded it and added planing and shingle mills which employed about 100 men by 1891. By that year the town also had a steam feed mill and a stop on the Menomonie branch of the Chi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chippewa County, Wisconsin
Chippewa County is a county located in the U.S. state of Wisconsin. It is named for the historic Chippewa people, also known as the Ojibwe, who long controlled this territory.

Fujita Scale
The Fujita scale (F-Scale; ), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation. The official Fujita scale category is determined by meteorologists and engineers after a ground or aerial damage survey, or both; and depending on the circumstances, ground-swirl patterns (cycloidal marks), weather radar data, witness testimonies, media reports and damage imagery, as well as photogrammetry or videogrammetry if motion picture recording is available. The Fujita scale was replaced with the Enhanced Fujita scale (EF-Scale) in the United States in February 2007. In April 2013, Canada adopted the EF-Scale over the Fujita scale along with 31 "Specific Damage Indicators" used by Environment Canada (EC) in their ratings. Background The scale was introduced in 1971 by Ted Fujita of the University of Chicago, in collaboration with Allen Pearson, head of the National Sev ...

Tornadoes
A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern. Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than , are about across, and travel several kilometers (a few miles) before dissipating. The most extreme tornadoes can attain wind speeds of more than , are more than in diameter, and stay on the ground for more than 100 k ...

Downburst
In meteorology, a downburst is a strong downward and outward gushing wind system that emanates from a point source above and blows radially, that is, in straight lines in all directions from the area of impact at surface level. Capable of producing damaging winds, it may sometimes be confused with a tornado, where high-velocity winds circle a central area, and air moves inward and upward. These usually last for seconds to minutes. Downbursts are particularly strong downdrafts within thunderstorms (or deep, moist convection as sometimes downbursts emanate from cumulonimbus or even cumulus congestus clouds that are not producing lightning). Downbursts are most often created by an area of significantly precipitation-cooled air that, after reaching the surface ( subsiding), spreads out in all directions producing strong winds. Dry downbursts are associated with thunderstorms that exhibit very little rain, while wet downbursts are created by thunderstorms with significant amounts o ...

Michigan
Michigan () is a state in the Great Lakes region of the upper Midwestern United States.

Georgia is the largest state by land area alone east of the Mississippi and Michigan the second-largest. Its capital is Lansing, and its largest city is Detroit. Metro Detroit is among the nation's most populous and largest metropolitan economies. Its name derives from a gallicized variant of the original Ojibwe word (), meaning "large water" or "large lake". Michigan consists of two peninsulas. The Lower Peninsula resembles the shape of a mitten, and comprises a majority of the state's land area. The Upper Peninsula (often called "the U.P.") is separated from the Lower Peninsula by the Straits of Mackinac, a channel that joins Lak ...

Off-the-air
In the broadcasting industry, a dark television station or silent radio station is one that has gone off the air for an indefinite period of time. Usually unlike dead air (broadcasting only silence), a station that is dark or silent does not even transmit a carrier signal. U.S. law Transmitter operations According to the U.S. Federal Communications Commission (FCC), a radio or television station is considered to have gone dark or silent if it is to be off the air for thirty days or longer. Prior to the Telecommunications Act of 1996, a "dark" station was required to surrender its broadcast license to the FCC, leaving it vulnerable to another party applying for it while its current owner was making efforts to get it back on the air. Following the 1996 landmark legislation, a licensee is no longer required to surrender the license while dark. Instead, the licensee may apply for a "Notification of Suspension of Operations/Request for Silent STA" (FCC Form 0386), stating the reas ...

Anemometer
In meteorology, an anemometer () is a device that measures wind speed and direction. It is a common instrument used in weather stations. The earliest known description of an anemometer was by Italian architect and author Leon Battista Alberti (1404–1472) in 1450. History The anemometer has changed little since its development in the 15th century. Alberti is said to have invented it around 1450. In the ensuing centuries numerous others, including Robert Hooke (1635–1703), developed their own versions, with some mistakenly credited as its inventor. In 1846, John Thomas Romney Robinson (1792–1882) improved the design by using four hemispherical cups and mechanical wheels. In 1926, Canadian meteorologist John Patterson (1872–1956) developed a three-cup anemometer, which was improved by Brevoort and Joiner in 1935. In 1991, Derek Weston added the ability to measure wind direction. In 1994, Andreas Pflitsch developed the sonic anemometer. Velocity anemometers Cup anemomet ...
