List Of Bureau Of Meteorology Weather Radars
Overview Australia's weather radars are operated by the Bureau of Meteorology, an executive agency of the Australian Government. The radar network is continually being upgraded with new technology such as doppler and dual polarisation to provide better now-casting. Doppler radars are able to detect the movement of precipitation, making it very useful in detecting damaging winds associated with precipitation, and determining if a thunderstorm has a rotating updraft, a key indicator of the presence of the most dangerous type of thunderstorm, a supercell. The new dual polarisation radars give forecasters the ability to: *Detect debris in the atmosphere, leading to more accurate tornado warnings; *Distinguish between different precipitation types, leading to better estimations of hail size and severity; *Better identify areas of heavy rainfall, leading to more accurate flood warnings; *Discern between precipitation and non-meteorological echoes such as chaff, birds, and insects. ...

Hillston, New South Wales
Hillston is a township in western New South Wales, Australia, in Carrathool Shire, on the banks of the Lachlan River. It was founded in 1863 and at the had a population of 1,465. History John Oxley and his exploration party were the first European visitors to the Hillston district, in 1817. Oxley wrote in his journal: "country uninhabitable and useless for all purposes of civilised man". In 1839 William Hovell followed the Lachlan River to near the site of present-day Hillston and took up a pastoral holding called "Bellingerambil" (later named "Cowl Cowl"). Redbank The locality of present-day Hillston was a crossing-place for stock on the Lachlan River. The earliest European name for the place was 'Daisy Plains' or ‘Daisy Hill’.‘Back to Hillston Week’ (souvenir booklet), September 1931. Later it became known as "Redbank" (following the Wiradjuri name 'Melnunni', meaning "red soil"). In 1863 a stockman named William Ward Hill from nearby "Roto" station established an ...

WSR-74
WSR-74 radars were Weather Surveillance Radars designed in 1974 for the National Weather Service. They were added to the existing network of the WSR-57 model to improve forecasts and severe weather warnings. Some have been sold to other countries like Australia, Greece, and Pakistan. Radar properties There are two types in the WSR-74 series, which are almost identical except for operating frequency. The WSR-74C (used for local warnings) operates in the C band, and the WSR-74S (used in the national network) operates in the S band (like the WSR-57 and the current WSR-88D). S band frequencies are better suited because they are not attenuated significantly in heavy rain while the C Band is strongly attenuated, and has a generally shorter maximum effective range. The WSR-74C uses a wavelength of 5.4 cm.Paul Sirvatka. "WSR - Weather Surveillance Radar." Radar.

Captains Flat
Captains Flat is a town in the Southern Tablelands of rural New South Wales, Australia, in Queanbeyan-Palerang Regional Council. It is south of Queanbeyan. Captains Flat township is bounded by the non-urban parts of the locality of Captains Flat in the north, east and west, and Captains Flat Road, the Molonglo River and Foxlow Street in the south. Name It is suggested the town took its name from a white bullock named "Captain" who would slip away from Foxlow station, 12 km away, to graze grassy flatlands near the Molonglo River. History Prior to European settlement, the area was inhabited by Ngarigo Aboriginal people. The town formed as a result of mining for gold, silver, lead, zinc, copper and iron pyrites in the hills surrounding the upper reaches of the Molonglo River. The town boomed from 1881 to 1899, but went into a rapid decline until 1939, when rail access revived mining activity for another 23 years. Mining Copper was found in the area in 1874 by J.E.

S Band
The S band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a part of the microwave band of the electromagnetic spectrum covering frequencies from 2 to 4 gigahertz (GHz). Thus it crosses the conventional boundary between the UHF and SHF bands at 3.0 GHz. The S band is used by airport surveillance radar for air traffic control, weather radar, surface ship radar, and some communications satellites, especially those used by NASA to communicate with the Space Shuttle and the International Space Station. The 10 cm radar short-band ranges roughly from 1.55 to 5.2 GHz. The S band also contains the 2.4–2.483 GHz ISM band, widely used for low power unlicensed microwave devices such as cordless phones, wireless headphones (Bluetooth), wireless networking (WiFi), garage door openers, keyless vehicle locks, baby monitors as well as for medical diathermy machines and microwave ovens (typically at 2.495 GHz).

C Band (IEEE)
The C band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4.0 to 8.0 gigahertz (GHz). However, the U.S. Federal Communications Commission C band proceeding and auction, designated 3.7–4.2 GHz as C band. The C band is used for many satellite communications transmissions, some Wi-Fi devices, some cordless telephones, as well as some Radar and weather radar systems. Use in satellite communication The communications C band was the first frequency band that was allocated for commercial telecommunications via satellites. The same frequencies were already in use for terrestrial microwave radio relay chains. Nearly all C-band communication satellites use the band of frequencies from 3.7 to 4.2 GHz for their downlinks, and the band of frequencies from 5.925 to 6.425 GHz for their uplinks. Note that by using the band from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
