Heat Wave Of 2006 Derecho Series
The heat wave of 2006 derecho series were a set of derechos — severe winds with powerful thunderstorms — that occurred on July 17–21, 2006. The first storms hit a wide swath of north-central and northeastern North America that stretched from the Upper Midwest through much of Ontario and into the northeastern United States. Another round struck the middle Mississippi River Valley, including two derechos that hit St. Louis, Missouri. The storms left more than three million people without power, some more than once and some for weeks. Northeastern Ontario derecho (July 17, 2006) Northern Michigan and Northeastern Ontario The derecho originated from a severe thunderstorm that was forming across portions of the Upper Peninsula and the northernmost parts of the lower Peninsula of Michigan in the early afternoon hours of July 17. It crossed the North Channel into Northeastern Ontario near Sault Ste. Marie, where it quickly developed into a derecho line. As it ...

Derecho
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, esp ...

Eastern Daylight Time
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callander, Ontario
The Municipality of Callander (formerly the Township of North Himsworth) is a township in central Ontario, Canada, located at the southeast end of Lake Nipissing in the Almaguin Highlands region of the District of Parry Sound. The municipality is located on Callander Bay, just south of North Bay. The municipality renamed itself from North Himsworth to Callander in 2003, adopting the name of its major community because, in the words of then-mayor Bill Brazeau, "Nobody knew where North Himsworth was." Communities The main community of Callander is located in the northeast corner of the municipality, along the eastern shore of Callander Bay. The south shore of Callander Bay and Lake Nipissing (southwest of the town) represents the rural population of Callander, which primarily runs along Highway 654 West. This area includes the communities of Wisawasa and Lighthouse Beach. History Callander Bay is an eroded Proterozoic volcanic pipe formed by the violent, supersonic erupt ...

West Nipissing, Ontario
West Nipissing is a municipality in Northeastern Ontario, Canada, on Lake Nipissing in the Nipissing District. It was formed on January 1, 1999, with the amalgamation of seventeen and a half former town, villages, townships and unorganized communities. It is the most bilingual community in Ontario, with 73.4% of its population fluent in both English and French. Communities The primary administrative and commercial centre of West Nipissing is the community of Sturgeon Falls, which is situated on the Sturgeon River, north of Lake Nipissing and west of North Bay on Highway 17, part of the Trans-Canada Highway. Roughly half the population of West Nipissing lives in Sturgeon Falls. Field is located on Highway 64, approximately north of Sturgeon Falls. In 1979, the Sturgeon River overflowed its banks, flooding the town's centre. Many houses were demolished and rebuilt on higher ground nearby. The Thistle Fire Tower is to be dismantled and re-erected here as a tourist attraction. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tornado Warning
A tornado warning (SAME code: TOR) is a severe weather warning product issued by regional offices of weather forecasting agencies throughout the world to alert the public when a tornado has been reported or indicated by weather radar within the parent severe thunderstorm. It can be issued after a tornado, funnel cloud and rotation in the clouds has been witnessed by the public, storm chasers, emergency management or law enforcement, and indicates that residents in the affected areas should take immediate safety precautions. A warning should not be confused with a tornado watch, issued in the United States by the Storm Prediction Center (SPC) and in other countries by applicable regional forecasting agencies or national severe weather guidance centers, which only indicates that conditions are favorable for the formation of tornadoes. Although a tornado warning is generally a higher alert level than a tornado watch, in the U.S., it can be surpassed by a higher-level alert—str ...

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 anemom ...

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lens (optics), lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Masts And Towers
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North Bay, Ontario
North Bay is a city in Northeastern Ontario, Canada. It is the seat of Nipissing District, Ontario, Nipissing District, and takes its name from its position on the shore of Lake Nipissing. North Bay developed as a railroad centre, and its airport was an important military location during the Cold War. History The site of North Bay is part of a historic canoe route where Samuel de Champlain took a party up the Ottawa River, through present-day Mattawa, on to Trout Lake and via the La Vase Creek to Lake Nipissing. Apart from Indigenous people, voyageurs and surveyors, there was little activity in the Lake Nipissing area until the arrival of the Canadian Pacific Railway (CPR) in 1882. That was the point where the Canada Central Railway (CCR) extension ended. The CCR was owned by Duncan McIntyre (businessman), Duncan McIntyre who amalgamated it with the CPR and became one of the handful of officers of the newly formed CPR. The CCR started in Brockville and extended to Pembroke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
