1947 Sydney Hailstorm
The 1947 Sydney hailstorm was a natural disaster which struck Sydney, Australia, on 1 January 1947. The storm cell developed on the morning of New Year's Day, a public holiday in Australia, over the Blue Mountains, hitting the city and dissipating east of Bondi in the mid-afternoon. At the time, it was the most severe storm to strike the city since recorded observations began in 1792.Newman (1947), p. 23. The high humidity, temperatures and weather patterns of Sydney increased the strength of the storm. The cost of damages from the storm were, at the time, approximately GB£750,000 (US$3 million); this is the equivalent of around A$45 million in modern figures.Reuters (1947), p. 4. The supercell dropped hailstones larger than in diameter,Whitaker (2005), p. 98.Lee, ''et al.'' (2000), p. 579. with the most significant damage occurring in the central business district and eastern suburbs of Sydney.Whitaker (2005), p. 95. The event caused around 1000 injuries, with be ...

The name Rose Bay was used as early as 1788 by Captain John Hunter. HMAS ''Tingira'', named after an Aboriginal word for 'open sea' was moored in Rose Bay from 1912 to 1927. It was used to train over 3,000 Australian sailors, many for service in World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteorology
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water.

Sydney Harbour Bridge
The Sydney Harbour Bridge is a steel through arch bridge in Sydney, spanning Port Jackson, Sydney Harbour from the Sydney central business district, central business district (CBD) to the North Shore (Sydney), North Shore. The view of the bridge, the harbour, and the nearby Sydney Opera House is widely regarded as an iconic image of Sydney, and of Australia itself. Nicknamed "The Coathanger" because of its arch-based design, the bridge carries rail, vehicular, bicycle and pedestrian traffic. Under the direction of John Bradfield (engineer), John Bradfield of the NSW Public Works, New South Wales Department of Public Works, the bridge was designed and built by British firm Dorman Long of Middlesbrough, and opened in 1932. The bridge's general design, which Bradfield tasked the NSW Department of Public Works with producing, was a rough copy of the Hell Gate Bridge in New York City. This general design document, however, did not form any part of the request for tender, which remain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liverpool, New South Wales
Liverpool is a suburb of Greater Western Sydney, in the state of New South Wales, Australia. It is located approximately south-west of the Sydney CBD. Liverpool is the administrative seat of the local government area of the City of Liverpool and is situated in the Cumberland Plain. History Liverpool is one of the oldest urban settlements in Australia, founded on 7 November 1810 as an agricultural centre by Governor Lachlan Macquarie. He named it after Robert Banks Jenkinson, Earl of Liverpool, who was then the Secretary of State for the Colonies and the English city of Liverpool, upon which some of the area's architecture is based. Liverpool is at the head of navigation of the Georges River and combined with the Great Southern Railway from Sydney to Melbourne reaching Liverpool in the late 1850s, Liverpool became a major agricultural and transportation centre as the land in the district was very productive. Until the 1950s, Liverpool was still a satellite town with an a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cirrus Cloud
Cirrus ( cloud classification symbol: Ci) is a genus of high cloud made of ice crystals. Cirrus clouds typically appear delicate and wispy with white strands. Cirrus are usually formed when warm, dry air rises, causing water vapor deposition onto rocky or metallic dust particles at high altitudes. Globally, they form anywhere between above sea level, with the higher elevations usually in the tropics The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referr ... and the lower elevations in more Polar regions of Earth, polar regions. Cirrus clouds can form from the tops of cumulonimbus cloud, thunderstorms and tropical cyclones and sometimes predict the arrival of precipitation, rain or storms. Although they are a sign that rain and maybe storms are on the way, cirrus themselves drop no more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtain
A curtain is a piece of cloth or other material intended to block or obscure light, air drafts, or (in the case of a shower curtain), water. A curtain is also the movable screen or drape in a theatre that separates the stage from the auditorium or that serves as a backdrop/background. Curtains are often hung on the inside of a building's windows to block the passage of light. For instance, at night to aid sleeping, or to stop light from escaping outside the building (stopping people outside from being able to see inside, often for privacy reasons). In this application, they are also known as "draperies". Curtains hung over a doorway are known as portières. Curtains come in a variety of shapes, materials, sizes, colours, and patterns. They often have their own sections within department stores, while some shops are completely dedicated to selling curtains. Curtains vary according to cleanability, ultraviolet light deterioration, oil and dust retention, noise absorption, fire res ...

Mottle
Mottle is a pattern of irregular marks, spots, streaks, blotches or patches of different shades or colours. It is commonly used to describe the surface of plants or the skin of animals. In plants, mottling usually consists of yellowish spots on plants, and is usually a sign of disease or malnutrition. Many plant viruses cause mottling, some examples being: * Tobacco vein mottling virus * Bean pod mottle virus Mottling is sometimes used to describe uneven discolored patches on the skin of humans as a result of cutaneous ischemia (lowered blood flow to the surfaces of the skin) or Herpes zoster infections. The medical term for mottled skin is dyschromia. Although this is not always the case, mottling can occur in the dying patient and commonly indicates that the end of life is near. Mottling usually occurs in the extremities (lower first) and progresses up as cardiac function declines and circulation throughout the body is poor. In animals, mottling may be a sign of disease, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloud
In meteorology, a cloud is an aerosol consisting of a visible mass of miniature liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body or similar space. Water or various other chemicals may compose the droplets and crystals. On Earth, clouds are formed as a result of saturation of the air when it is cooled to its dew point, or when it gains sufficient moisture (usually in the form of water vapor) from an adjacent source to raise the dew point to the ambient temperature. They are seen in the Earth's homosphere, which includes the troposphere, stratosphere, and mesosphere. Nephology is the science of clouds, which is undertaken in the cloud physics branch of meteorology. There are two methods of naming clouds in their respective layers of the homosphere, Latin and common name. Genus types in the troposphere, the atmospheric layer closest to Earth's surface, have Latin names because of the universal adoption of Luke Howard's ...

Bureau Of Meteorology
The Bureau of Meteorology (BOM or BoM) is an executive agency of the Australian Government responsible for providing weather services to Australia and surrounding areas. It was established in 1906 under the Meteorology Act, and brought together the state meteorological services that existed before then. The states officially transferred their weather recording responsibilities to the Bureau of Meteorology on 1 January 1908. History The Bureau of Meteorology was established on 1 January 1908 following the passage of the ''Meteorology Act 1906''. Prior to Federation in 1901, each colony had had its own meteorological service, with all but two colonies also having a subsection devoted to astronomy. In August 1905, federal home affairs minister Littleton Groom surveyed state governments for their willingness to cede control, finding South Australia and Victoria unwilling. However, at a ministerial conference in April 1906 the state governments agreed to transfer responsibility for m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mascot, New South Wales
Mascot is a suburb in the Inner-South of Sydney, in the state of New South Wales, Australia. Mascot is located 7 kilometres south of the Sydney central business district and is one of the administrative centres of the Bayside Council. A small part of Mascot is located in the Inner West Council. Mascot is on the north-west side of Botany Bay and contains Sydney Airport. History The first land grants in the area were made in 1835, with market gardening being the main land use. Subdivision followed the construction of Botany Road in 1875 and a municipality known as North Botany was formed in 1888. A racecourse operated in this area in 1904 on land that was formerly owned by the Australian Golf Club. The race course was known as Ascot, named after its famous counterpart in England. Residents wanted the area to have an individual identity and a referendum was held in 1911 to choose between Ascot, and Booralee. An objection from the postal authorities to the use of 'Ascot' led ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
