Weather Spotters
Weather spotting is observing weather for the purpose of reporting to a larger group or organization. Examples include National Weather Service (NWS) co-op observers and Skywarn storm spotters. Storm spotters A storm spotter is a specific type of weather spotter. In the U.S., these volunteers are usually trained by the National Weather Service or local Skywarn group, and are given a phone number, internet outlet, or amateur radio frequency to report to if a severe weather event, such as a tornado, severe thunderstorm, or flash flood occurs where the spotter is located. They add ground truth information to remote sensing technology such as weather radar. Canwarn is the national storm spotting program of Canada, Skywarn Europe covers about a dozen countries (including the U.K., which is also covered by TORRO), and Australia also has a program organized by the Bureau of Meteorology.

Weather
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere. Weather refers to day-to-day temperature, precipitation, and other atmospheric conditions, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth. Weather is driven by air pressure, temperature, and moisture differences between one place and another. These differences can occur due to the Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations: the Hadley cell, the Ferrel cell, the polar cell, and the jet stream.

Citizen Weather Observer Program
The Citizen Weather Observer Program (CWOP) is a network of privately owned electronic weather stations concentrated in the United States but also located in over 150 countries. Network participation allows volunteers with computerized weather stations to send automated surface weather observations to the National Weather Service (NWS) by way of the Meteorological Assimilation Data Ingest System (MADIS). This data is then used by the Rapid Refresh (RAP) forecast model to produce short term forecasts (3 to 12 hours into the future) of conditions across the contiguous United States. Observations are also redistributed to the public. Origin The CWOP was originally set up by amateur radio operators experimenting with packet radio, but now includes Internet-only connected stations, as well as amateur radio Automatic Packet Reporting System (APRS) stations. , more than 13,000 stations worldwide report regularly to the network.

Tornado
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 ...

Thunderstorm
A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder. Relatively weak thunderstorms are sometimes called thundershowers. Thunderstorms occur in a type of cloud known as a cumulonimbus. They are usually accompanied by strong winds and often produce heavy rain and sometimes snow, sleet, or hail, but some thunderstorms produce little precipitation or no precipitation at all. Thunderstorms may line up in a series or become a rainband, known as a squall line. Strong or severe thunderstorms include some of the most dangerous weather phenomena, including large hail, strong winds, and tornadoes. Some of the most persistent severe thunderstorms, known as supercells, rotate as do cyclones. While most thunderstorms move with the mean wind flow through the layer of the troposphere that they occupy, vertical wind shear sometimes causes a de ...

Storm Chasing
Storm chasing is broadly defined as the deliberate pursuit of any severe weather phenomenon, regardless of motive, but most commonly for curiosity, adventure, scientific investigation, or for news or media coverage. A person who chases storms is known as a storm chaser or simply a chaser. While witnessing a tornado is the single biggest objective for most chasers, many chase thunderstorms and delight in viewing cumulonimbus and related cloud structures, watching a barrage of hail and lightning, and seeing what skyscapes unfold. A smaller number of storm chasers attempt to intercept tropical cyclones and waterspouts. Nature of and motivations for chasing Storm chasing is chiefly a recreational endeavor, with chasers usually giving their motives as photographing or video recording a storm, or for various personal reasons. These can include the beauty of the views afforded by the sky and land, the mystery of not knowing precisely what will unfold, the journey to an undetermined ...

Manchester, New Hampshire
Manchester is a city in Hillsborough County, New Hampshire, United States. It is the most populous city in New Hampshire. At the 2020 census, the city had a population of 115,644. Manchester is, along with Nashua, one of two seats of New Hampshire's most populous county, Hillsborough County. Manchester lies near the northern end of the Northeast megalopolis and straddles the banks of the Merrimack River. It was first named by the merchant and inventor Samuel Blodgett, namesake of Samuel Blodget Park and Blodget Street in the city's North End. His vision was to create a great industrial center similar to that of the original Manchester in England, which was the world's first industrialized city. History The native Pennacook people called Amoskeag Falls on the Merrimack River—the area that became the heart of Manchester—''Namaoskeag'', meaning "good fishing place".

WMUR-TV
WMUR-TV (channel 9) is a television station licensed to Manchester, New Hampshire, United States, broadcasting ABC programming to most of New Hampshire. Owned by Hearst Television, the station maintains studios on South Commercial Street in downtown Manchester, and its transmitter is located on the south peak of Mount Uncanoonuc in Goffstown. Manchester is part of the larger Boston television market, making WMUR-TV part of a nominal duopoly with that city's ABC affiliate, WCVB-TV (channel 5); however, the two stations maintain separate operations. As a result, WMUR is the only New Hampshire-based television station with a news operation.
