Independence Day Derecho Of 1977
The Independence Day Derecho of 1977 was a derecho, or long-lived windstorm associated with a fast-moving band of thunderstorms, that occurred in the northern Great Plains of the U.S. on July 4, 1977. It lasted around 15½ hours. The derecho formed in Minnesota around 10 a.m. CDT on July 4 and became more intense around noon in the central part of the state. The derecho produced winds of in northern Wisconsin, felling thousands of trees. Wisconsin As the storm raced through Burnett, Washburn, Sawyer, Price, and Oneida counties, it caused a band of damage wide. Nearly of forest were badly damaged or destroyed. The derecho caused $24M in property damage. One person was killed and 35 were injured. Here is a summary of damage by county: * Sawyer County, Wisconsin - A wind gust of was measured at the Hayward airport. The downburst winds destroyed several homes and barns. Winds of were estimated at the Flambeau River State Forest. A woman was killed when a tree fell o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinelander, Wisconsin
Rhinelander is a city in and the county seat of Oneida County, Wisconsin, Oneida County, Wisconsin, United States. The population was 8,285 at the 2020 United States Census, 2020 census. History The area that eventually became the city of Rhinelander was originally called Pelican Rapids by early settlers, named for the stretch of rapids just above the convergence of the Wisconsin and Pelican Rivers. Around 1870, Anderson W. Brown of Stevens Point and Anson P. Vaughn traveled up the Wisconsin River to cruise timber for Brown's father, E. D. Brown. Upon arriving at the meeting point of the Wisconsin and Pelican Rivers at the site of John Curran's trading post, and seeing the high banks along the rapids and the excellent pine stands, Anderson Brown envisioned a mill town with a lumber mill powered by the waters of the Wisconsin River. Brown's vision did not come to fruition for some years, but after subsequent expeditions with others, including his brother and Rhinelander's first m ...

Ludington, Michigan
Ludington ( ) is the largest city and county seat of Mason County in the U.S. state of Michigan. As of the 2010 census, the city population was 8,076. Ludington is a harbor town located on Lake Michigan at the mouth of the Pere Marquette River. Many people come to Ludington year round for recreation, including boating and swimming on Lake Michigan, Hamlin Lake, and other smaller inland lakes, as well as hunting, fishing, and camping.

July 1977 Events In The United States
July is the seventh month of the year in the Julian and Gregorian calendars and is the fourth of seven months to have a length of 31 days. It was named by the Roman Senate in honour of Roman general Julius Caesar in 44 B.C., it being the month of his birth. Before then it was called Quintilis, being the fifth month of the calendar that started with March. It is on average the warmest month in most of the Northern Hemisphere, where it is the second month of summer, and the coldest month in much of the Southern Hemisphere, where it is the second month of winter. The second half of the year commences in July. In the Southern Hemisphere, July is the seasonal equivalent of January in the Northern hemisphere. "Dog days" are considered to begin in early July in the Northern Hemisphere, when the hot sultry weather of summer usually starts. Spring lambs born in late winter or early spring are usually sold before 1 July. July symbols *July's birthstone is the ruby, which symbolize ...

Natural Disasters In Michigan
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Derechos In The United States
A ''derecho'' (, from es, derecho, link=no , 'straight') is a widespread, long-lived, straight-line wind storm that is associated with a fast-moving group of severe thunderstorms known as a mesoscale convective system. Derechos can cause hurricanic and tornadic-force winds, heavy rains, and flash floods. In many cases, convection-induced winds take on a bow echo (backward "C") form of squall line, often forming beneath an area of diverging upper tropospheric winds, and in a region of both rich low-level moisture and warm-air advection. Derechos move rapidly in the direction of movement of their associated storms, similar to an outflow boundary (gust front), except that the wind remains sustained for a greater period of time (often increasing in strength after onset), and may exceed hurricane-force. A derecho-producing convective system may remain active for many hours and, occasionally, over multiple days. A warm-weather phenomenon, derechos occur mostly in summer, especiall ...

Bow Echo
A bow echo is the characteristic radar return from a mesoscale convective system that is shaped like an archer's bow. These systems can produce severe straight-line winds and occasionally tornadoes, causing major damage. They can also become derechos or form Line echo wave pattern (LEWP). Research The term "bow echo" was first used by Theodore Fujita in his May 1978 paper "Manual of Downburst Identification for Project NIMROD." In 2004, research was done to better anticipate the formation of bow echoes, specifically the formation of bow echoes from weakly organized squall lines and supercells. Researchers determined that bow echoes were most likely to occur in weakly organized cells. A Midwest Bow Echo Workshop was held in 2007, at which meteorologists gathered to share their research to better understand bow echoes. Formation A bow echo is associated with squall lines or lines of convective thunderstorms. These echoes can range in size from 20 to 200 km, and have a ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Hayward, Wisconsin
Hayward is a city in Sawyer County, Wisconsin, United States, next to the Namekagon River. The population was 2,318 at the 2010 census. It is the county seat of Sawyer County. The city is surrounded by the Town of Hayward. History Early history Hayward was "named for Anthony Judson Hayward, a lumberman who located the site for building a sawmill, around which the town grew." Logging began in the late 1850s. Loggers came from Cortland County, New York, Carroll County, New Hampshire, Orange County, Vermont, Down East Maine in what is now Washington County, Maine and Hancock County, Maine. These were "Yankee" migrants, descended from the English Puritans who had settled New England during the 1600s. They were mostly members of the Congregational Church. From the 1890s, immigrants came from a variety of countries such as Germany, Norway, Poland, Italy, Ireland, Czechoslovakia, and Sweden.
