Australian Bureau Of Statistics
The Australian Bureau of Statistics (ABS) is an List of Australian Government entities, Australian Government agency that collects and analyses statistics on economic, population, Natural environment, environmental, and social issues to advise the Australian Government. The bureau's function originated in the Commonwealth Bureau of Census and Statistics, established in 1905, four years after Federation, Federation of Australia; it took on its present name in 1975. The ABS conducts Australia's Census of Population and Housing every five years and publishes its findings online. History Efforts to count the population of Australia started in 1795 with "musters" that involved physically gathering a community to be counted, a practice that continued until 1825. The first colonial censuses were conducted in New South Wales in 1828; in Tasmania in 1841; South Australia in 1844; Western Australia in 1848; and Victoria in 1854. Each colony continued to collect statistics separately d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taree
Taree () is a city on the Mid North Coast, New South Wales, Australia. It and nearby Cundletown were settled in 1831 by William Wynter. Since then it has grown to a population of 26,381, and commands a significant agricultural district. Situated on a floodplain by the Manning River, it is 16 km from the Tasman Sea coast, and 317 km north of Sydney. Taree is within the local government area of Mid-Coast Council, the state electorate of Myall Lakes and the federal electorate of Lyne. Established in 1854 as a private town, it was proclaimed a municipality in 1885 and a city in 1981. Name The name Taree is derived from "tareebit", a Biripi word meaning ''tree by the river'', or more specifically, the Sandpaper Fig ('' Ficus coronata''). History The Biripi were the indigenous people of what is now known as Taree. The Aboriginal population of the Manning River was relatively dense before colonisation by Europeans. In 1826, Assistant Surveyor Henry Dangar was instru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coffs Harbour
Coffs Harbour, locally nicknamed Coffs, is a coastal city on the Mid North Coast of New South Wales, Australia, north of Sydney, and south of Brisbane. It is one of the largest urban centres on the North Coast, with a population of 78,759 as per 2021 census. The Gumbaynggirr, Gumbaynggirr people are the Traditional Owners of Coffs Harbour and the surrounding area, they have occupied this land for many thousands of years.

Coffs Harbour is near numerous national parks, including a marine n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diameter
In geometry, a diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest Chord (geometry), chord of the circle. Both definitions are also valid for the diameter of a sphere. In more modern usage, the length d of a diameter is also called the diameter. In this sense one speaks of diameter rather than diameter (which refers to the line segment itself), because all diameters of a circle or sphere have the same length, this being twice the radius r. :d = 2r \qquad\text\qquad r = \frac. The word "diameter" is derived from (), "diameter of a circle", from (), "across, through" and (), "measure". It is often abbreviated \text, \text, d, or \varnothing. Constructions With straightedge and compass, a diameter of a given circle can be constructed as the perpendicular bisector of an arbitrary chord. Drawing two diameters in this way can be used to locate the center of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hail
Hail is a form of solid Precipitation (meteorology), precipitation. It is distinct from ice pellets (American English "sleet"), though the two are often confused. It consists of balls or irregular lumps of ice, each of which is called a hailstone. Ice pellets generally fall in cold weather, while hail growth is greatly inhibited during low surface temperatures. Unlike other forms of ice, water ice precipitation, such as graupel (which is made of rime ice), ice pellets (which are smaller and Transparency and translucency, translucent), and snow (which consists of tiny, delicately crystalline flakes or needles), hailstones usually measure between and in diameter. The METAR reporting code for hail or greater is GR, while smaller hailstones and graupel are coded GS. Hail is possible during most thunderstorms (as it is produced by cumulonimbus), as well as within of the parent storm. Hail formation requires environments of strong, upward motion of air within the parent thunderst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric
An atmosphere () is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the outer region of a star, which includes the layers above the opacity (optics), opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules. The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), Carbon dioxide in Earth's atmosphere, carbon dioxide (0.04%) and trace gases. Most organisms use oxygen for respiration (physiology), respiration; lightning and bacteria perform nitrogen fixation which produces ammonia that is used to make nucleotides and amino acids; plants, algae, and cyanobacteria use carbon dioxide for photosynthesis. The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, solar wind, and cosmic rays ...

Severe Thunderstorm
A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustics, acoustic effect on the Earth's atmosphere, known as thunder. Relatively weak thunderstorms are sometimes called thundershowers. Thunderstorms occur in cumulonimbus clouds. They are usually accompanied by strong winds and often produce Heavy rain (meteorology), heavy rain and sometimes Thundersnow, snow, Ice pellets, sleet, or hail, but some thunderstorms can produce little or Dry thunderstorm, no precipitation at all. Thunderstorms may thunderstorm training, line up in a series or become a rainband, known as a squall line. Strong or #Severe thunderstorms, 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 thr ...

Bureau Of Meteorology (Australia)
The Bureau of Meteorology (BOM or BoM) is an executive agency of the Australian Government that is responsible for providing weather forecasts and meteorological services to Australia and neighbouring countries. It was established in 1906 under the Meteorology Act (Cth), 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 g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Erosion
Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of Wind wave, waves, Ocean current, currents, tides, wind-driven water, waterborne ice, or other impacts of storms. The landward retreat of the shoreline can be measured and described over a temporal scale of tides, seasons, and other short-term cyclic processes. Coastal erosion may be caused by hydraulic action, abrasion (geology), abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion. Softer areas become eroded much faster than harder ones, which typically result in landforms such as tunnels, bridges, columns, and Column, pillars. Over time the coast generally evens out. The softer areas fill up with sediment eroded from hard areas, and roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mean
A mean is a quantity representing the "center" of a collection of numbers and is intermediate to the extreme values of the set of numbers. There are several kinds of means (or "measures of central tendency") in mathematics, especially in statistics. Each attempts to summarize or typify a given group of data, illustrating the magnitude and sign of the data set. Which of these measures is most illuminating depends on what is being measured, and on context and purpose. The ''arithmetic mean'', also known as "arithmetic average", is the sum of the values divided by the number of values. The arithmetic mean of a set of numbers ''x''1, ''x''2, ..., x''n'' is typically denoted using an overhead bar, \bar. If the numbers are from observing a sample of a larger group, the arithmetic mean is termed the '' sample mean'' (\bar) to distinguish it from the group mean (or expected value) of the underlying distribution, denoted \mu or \mu_x.
