Brickfielder
The Brickfielder is a hot and dry wind in Southern Australia that develops in the country's deserts in late spring and summer, which heavily raises temperatures in the southeast coast. Etymology The term name was recorded in early 19th century, which emanated from the name of Brickfield Hill, a site which was a former brickworks in the centre of Sydney CBD. The area was associated with dusty wind that conveyed clouds of reddish dust from the brickworks over the emerging city. A more frequently used term for the winds is a "burster". Development The brickfielder precedes the passage of a frontal zone of a low pressure system passing by, and causes severe dust storms that often last for days and led to its naming as the winds blow up red brick dust. It blows to the coastal regions in the south from the outback, reaching the capitals of Adelaide and Melbourne to south, and Sydney to the east. The dry northwesterly desert air from the interior of Australia transports dusty clouds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southeast Australian Foehn
The southeast Australian foehn is a westerly foehn wind and a rain shadow effect that usually occurs on the coastal plain of southern New South Wales, and as well as in eastern Victoria and eastern Tasmania, on the leeward side of the Great Dividing Range.Rain Shadows by Don White. Australian Weather News. Willy Weather. Retrieved 24 May 2021. Ranging from cool to hot (depending on the season), the effect occurs when westerly winds descend steeply from the Great Dividing Range onto the coastal slopes, whereby causing major adiabatic compression (which is the rate at which temperature decreases with altitude) and a substantial loss of moisture. The effect is known by other names such as the Australian foehn, the Australian ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brickfield Hill
Brickfield Hill is a City of Sydney locality in inner city Sydney, Australia. The name was used for the surrounding settlement serving the colony's growing need for bricks, and today is part of the suburb of Surry Hills. History Brickfield Hill was a Sydney postal address until postcodes were introduced in 1967, and roughly covered the area between Sydney Town Hall and Central Station. The area was used for brick-making, hence the term, up until the 1840s when land values rose and merchant stores, warehouses, and housing became more prominent, although the area remained a relatively poor 'slum' area of the city. In 1905, following the destruction of their Haymarket store by fire in 1901, Anthony Hordern & Sons opened their new "Palace Emporium" on Brickfield Hill, the construction of which involved the demolition of several houses including Samuel Hordern's birthplace. Following the demise of the Hordern retailing empire, the building was used by the New South Wales Institute of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dust Over Southeast Australia
Dust is made of fine particles of solid matter. On Earth, it generally consists of particles in the atmosphere that come from various sources such as soil lifted by wind (an aeolian process), volcanic eruptions, and pollution. Dust in homes is composed of about 20–50% dead skin cells. The rest, and in offices, and other human environments is composed of small amounts of plant pollen, human hairs, animal fur, textile fibers, paper fibers, minerals from outdoor soil, burnt meteorite particles, and many other materials which may be found in the local environment. Atmospheric Atmospheric or wind-borne fugitive dust, also known as ''aeolian dust'', comes from arid and dry regions where high velocity winds are able to remove mostly silt-sized material, deflating susceptible surfaces. This includes areas where grazing, ploughing, vehicle use, and other human behaviors have further destabilized the land, though not all source areas have been largely affected by anthropo ...

Cyclone
In meteorology, a cyclone () is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. Cyclogenesis is the process of cyclone formation and ...

Environment Of Australia
The Australian environment ranges from virtually pristine Antarctic territory and rainforests to degraded industrial areas of major cities. Forty distinct ecoregions have been identified across the Australian mainland and islands. Central Australia has a very dry climate. The interior has a number of deserts while most of the coastal areas are populated. Northern Australia experiences tropical cyclones while much of the country is prone to periodic drought. This dry and warm environment and exposure to cyclones, makes Australia particularly vulnerable to climate change -- with some areas already experiencing increases in wildfires and fragile ecosystems. The island ecology of Australia has led to a number of unique endemic plant and animal species, notably marsupials like the kangaroo and koala. Agriculture and mining are predominant land uses which cause negative impacts on many different ecosystems. The management of the impact on the environment from the mining industry ...

Winds
Wind is the natural movement of air or other gases relative to a planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics and subtropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail. Winds are commonly classified by their spatial scale, their speed and direction, the forces that cause them, the regions in which they occur, and their effect. Winds have various asp ...

Harmattan
The Harmattan is a season in West Africa that occurs between the end of November and the middle of March. It is characterized by the dry and dusty northeasterly trade wind, of the same name, which blows from the Sahara over West Africa into the Gulf of Guinea. The name is related to the word in the Twi language. The temperature is cold in most places, but can also be hot in certain places, depending on local circumstances. The Harmattan blows during the dry season, which occurs during the months with the lowest sun. In this season the subtropical ridge of high pressure stays over the central Sahara and the low-pressure Intertropical Convergence Zone (ITCZ) stays over the Gulf of Guinea. On its passage over the Sahara, the Harmattan picks up fine dust and sand particles (between 0.5 and 10 microns). It is also known as the "doctor wind", because of its invigorating dryness compared with humid tropical air. Effects This season differs from winter, because it is characterized ...

Zonda Wind
Zonda wind ( es, viento zonda) is a regional term for the foehn wind that often occurs on the eastern slope of the Andes, in Argentina. Formation The Zonda is a dry wind (often carrying dust) which comes from the polar maritime air, warmed by descent from the crest, which is approximately above sea level. It may exceed a velocity of . The Zonda wind is produced by the northeastward movement of polar fronts, and although is hot and dry at the low-lands, it is the main mechanism for snow precipitation at the high altitude chains, where it looks as ''viento blanco'', reaching speeds sometimes over 200 km/h. Thus, instead of being a snow-eater, this wind is particularly important for this arid region, as it is connected to the buildup of the winter snow cover and accumulation over the scarce local glaciers. Occurrence While this type of föhn wind may occur over most central parts of western Argentina, its effects are more impressive in La Rioja, San Juan, and northern Mendoza pro ...

Climate Of Australia
Australia's climate is governed mostly by its size and by the hot, sinking air of the subtropical high pressure belt (subtropical ridge or Australian High). This moves north-west and north-east with the seasons. The climate is variable, with frequent droughts lasting several seasons, thought to be caused in part by the El Niño-Southern Oscillation. Australia has a wide variety of climates due to its large geographical size. The largest part of Australia is desert or semi-arid. Only the south-east and south-west corners have a temperate climate and moderately fertile soil. The northern part of the country has a tropical climate, varying between grasslands and desert. Australia holds many heat-related records: the continent has the hottest extended region year-round, the areas with the hottest summer climate, and the highest sunshine duration. Because Australia is a medium-sized continent, separated from polar regions by the Southern Ocean, it is not subject to movements of fr ...
