Pannawonica, Western Australia
Pannawonica is an iron-ore mining town located in the Pilbara region of Western Australia, near the Robe River, about south-west from Karratha and North from Perth. At the 2016 census, Pannawonica had a population of 695. In 2011 and again in 2016, it reportedly had the highest median weekly income of any town in Western Australia and most likely Australia, due to the high income of its mine workers.Salt B Richest and poorest live in outback towns' The Australian Business, 27 November 2008 History Pannawonica was built on Yalleen Station in 1970 by Cliffs Robe River Iron Associates or C.R.R.I.A.

Electoral District Of North West Central
North West Central is an electoral district of the Legislative Assembly in the Australian state of Western Australia. The district is mostly based in the rural north-west of Western Australia. It is currently a marginal seat for the Nationals. History First known as North West Coastal, the district was first created for the 2005 state election, incorporating territory from the abolished districts of Burrup and Ningaloo. The seat was won by Labor MP, and then member for Burrup, Fred Riebeling. The district was expanded for the 2008 state election, incorporating more inland territory which resulted in the name change to North West. With Riebeling's decision to retire, the contest pitted Labor MP Vince Catania, then a member of the Legislative Council, against Liberal candidate, and former Ningaloo MP, Rod Sweetman, with Catania emerging victorious. On 20 July 2009, Catania announced his decision to leave the Labor Party to join the rival National Party. The 2013 state e ...

Hot Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSk'' and ''BSh'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as it usually can't support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): *multiply by ...

Pisolite
A pisolite is a sedimentary rock made of pisoids, which are concretionary grains – typically of calcium carbonate which resemble ooids, but are more than 2 mm in diameter. These grains are approximately spherical and have concentric layers reaching 10 mm in diameter. The name derives from the Hellenic word for pea. Bauxites, limonites, and siderites often have a pisolitic structure. See also * Ooid * Oolite Oolite or oölite (''egg stone'') is a sedimentary rock formed from ooids, spherical grains composed of concentric layers. The name derives from the Ancient Greek word for egg (ᾠόν). Strictly, oolites consist of ooids of diameter 0.25–2 ... References Further reading * Sedimentary rocks {{petrology-stub ...

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] |
Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling round ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Division Of Durack
The Division of Durack is an Australian Electoral Division in the state of Western Australia. History The Division is named after the pioneering Durack family, upon whom Dame Mary Durack based her popular historical novels. Created to replace parts of the divisions of Kalgoorlie (which was abolished) and O'Connor, it elected its first member at the 2010 election. It was created as a comfortably safe Liberal seat. Sitting Kalgoorlie MP Barry Haase contested the seat for the Liberals and won. Haase announced he would not recontest Durack at the next election on 15 June 2013. The seat was won at the 2013 election by Liberal candidate Melissa Price. She held the seat without serious difficulty until the 2022 election, when she suffered a swing of over 10 percent to make the seat marginal for the first time. Geography Since 1984, federal electoral division boundaries in Australia have been determined at redistributions by a redistribution committee appointed by the Australian ...

Hot Desert Climate
The desert climate or arid climate (in the Köppen climate classification ''BWh'' and ''BWk''), is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the second most common type of climate on earth after the polar climate. There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (''BWh''), and a cold desert climate (''BWk''). To delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: most commonly a mean annual temperature of , or sometimes the coldest month's mean temperature of , so that a location with a ''BW'' type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid sub ...
