1979–1983 Eastern Australian Drought
Between 1979 and 1983 almost all of eastern Australia was affected by a major drought. Although in some places such as the South Coast the drought was almost continuous, in most of the affected region the major years of drought were 1980 and 1982. Background The 1970s had been an exceptionally wet decade over eastern Australia, despite short-term droughts from April to August 1976 and June to December 1977. 1978 was especially wet in the southern coast districts of New South Wales and East Gippsland because southern low pressure systems consistently redeveloped over the east coast. Orbost's 1978 rainfall of is as much as 256 mm (10 inches) above its previous record from 1935. In the winter, unseasonal rains struck normally bone-dry areas of northern Australia, and the wet season arrived early in the north in October. Though the Wet was not abnormally powerful in November and December, southeastern Australia remained exceptionally wet. 1979 The year 1979 began with ex ...

Anticyclone
An anticyclone is a weather phenomenon defined as a large-scale circulation of winds around a central region of high atmospheric pressure, clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere as viewed from above (opposite to a cyclone). Effects of surface-based anticyclones include clearing skies as well as cooler, drier air. Fog can also form overnight within a region of higher pressure. Mid-tropospheric systems, such as the subtropical ridge, deflect tropical cyclones around their periphery and cause a temperature inversion inhibiting free convection near their center, building up surface-based haze under their base. Anticyclones aloft can form within warm-core lows such as tropical cyclones, due to descending cool air from the backside of upper troughs such as polar highs, or from large-scale sinking such as a subtropical ridge. The evolution of an anticyclone depends upon variables such as its size, intensity, and extent of moist con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1982–83 El Niño Event
The 1982–1983 El Niño event was one of the strongest El Niño events since records were kept. It led to droughts in Indonesia and Australia, widespread flooding across the southern United States, lack of snow in the northern United States, and an anomalously warm winter across much of the mid-latitude regions of North America and Eurasia. The estimated global economic impact was over US$8 billion. This El Niño event also led to an abnormal number of hurricanes in the Pacific Ocean during this time span; the strongest hurricane up to 1983 hit Hawaii during the event. Meteorological progression Due to a variety of reasons, ranging from the lack of knowledge among the general public regarding El Niño events to the fact that a volcanic eruption in Mexico from El Chichón distracted many scientists from noticing the telltale signs, this event escaped the notice of the scientific world until 1983. As pointed out by Walter Sullivan, signs began to appear in early 1982, when a no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Gippsland
West Gippsland, a region of Gippsland in Victoria, Australia, extends from the southeastern limits of metropolitan Melbourne and Western Port Bay in the west to the Latrobe Valley in the east, and is bounded by the Strzelecki Ranges to the south and the Mount Baw Baw Plateau in the Great Dividing Range to the north. Geography The western part of the region around Western Port Bay and the Bunyip River is mostly flat (much of it having been reclaimed from the drained Koo Wee Rup Swamp), while the eastern part consists of low rolling hills. To the north these hills become steeper as they merge into the Great Dividing Range. In the mountainous north around Noojee logging remains an important industry, while a small winter resort is located to the northeast at Mount Baw Baw. Further to the east are the small township of Erica and the historic gold mining town of Walhalla. Nature reserves in the region include Bunyip State Park, Mount Worth State Park and Baw Baw National Park. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Median
In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value. The basic feature of the median in describing data compared to the mean (often simply described as the "average") is that it is not skewed by a small proportion of extremely large or small values, and therefore provides a better representation of a "typical" value. Median income, for example, may be a better way to suggest what a "typical" income is, because income distribution can be very skewed. The median is of central importance in robust statistics, as it is the most resistant statistic, having a breakdown point of 50%: so long as no more than half the data are contaminated, the median is not an arbitrarily large or small result. Finite data set of numbers The median of a finite list of numbers is the "middle" number, when those numbers are list ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeehan
Zeehan is a town on the west coast of Tasmania, Australia south-west of Burnie. It is part of the West Coast Council, along with the seaport Strahan, and neighbouring mining towns of Dundas, Rosebery and Queenstown. History The greater Zeehan area was inhabited by the indigenous Peerapper and Tommeginne clans of the North West group for over 10,000 years prior to the British colonisation of Tasmania. They were greatly coastal peoples, residing in small numbers on a diet consisting of muttonbirds, seals, swan eggs and cider gum, and constructed bark huts when strong westerly winds brought about rain and icy temperatures. European naming On 24 November 1642, Dutch explorer Abel Tasman became the first European explorer to sight and document the Heemskirk and West Coast Ranges. Tasman sailed his ships close to the coastal area which today encompasses the Southwest Conservation Area, south of Macquarie Harbour, but was unable to send a landing party ashore due to poor ...

Babinda
Babinda is a rural town and locality in the Cairns Region, Queensland, Australia. In the , the locality of Babinda had a population of 1,253 people. Geography Babinda is located south of Cairns. The town is noted for its proximity to Queensland's two highest mountains Mount Bartle Frere (Queensland's highest peak) and Mount Bellenden Ker. Babinda and Tully annually compete for the Golden Gumboot, an award for Australia's wettest town. Babinda is usually the winner, recording an annual average rainfall of over each year. History Babinda takes its name from the local Indigenous Australian language for ''mountain''. Other sources, however, claim it is a Yidinji word for ''water'', possibly referring to the high rainfall of the area. Babinda State School opened on 4 November 1914. Babinda Post Office opened by 1915 (a ''Babinda Creek'' receiving office had been open since 1891). The Babinda Sugar Mill opened on 15 September 1915. It closed on 23 February 2011. Babinda Pres ...

Hughenden, Queensland
Hughenden is a rural town and locality in the Flinders Shire, Queensland, Australia. In the , the locality of Hughenden had a population of 1,136 people. Geography Hughenden is situated on the banks of the Flinders River. Hughenden has the following mountains (from west to east): * Mount Walker () * Mount Mowbray () * Mount Devlin () * Mount Castor () * Mount Beckford () Hughenden is located on the Flinders Highway, west of Townsville and north-west of Brisbane, the state capital. The region around Hughenden is a major centre for the grazing of sheep and cattle. The main feed is annual grasses known as Flinders grass, which grow rapidly on the (by Australian standards) fertile grey or brown cracking clay soils after rain between November and March. However, because the rainfall is extremely erratic – at Hughenden itself it has ranged from in 1926 to in 1950 – droughts and floods are normal and stock numbers fluctuate greatly. The runoff from the Flinders R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Restrictions In Australia
Water restrictions have been enacted in many cities and regions in Australia, which is the Earth's driest inhabited continent, in response to chronic water shortages resulting from the widespread drought. Depending upon the location, these can include restrictions on watering lawns, using sprinkler systems, washing vehicles, hosing pavement, refilling swimming pools, etc. Overpopulation, evidence of drying climates, coupled with corresponding reductions in the supply of drinking water has led various state governments to consider alternative water sources to supplement existing sources, and to implement "water inspectors" who can issue penalties to those who waste water. Many states describe the different levels of water restrictions in terms of "stages": starting at Stage 1, for the least restrictive, going up as far as Stage 8. The highest level reached in the current drought has been stage 7 for Kingaroy. There are different definitions given to each "stage" in different st ...
