Cyclone Graham
Cyclone Graham of the 2002–03 Australian region cyclone season was a weak tropical storm that affected Australia during late February and early March 2003. Graham originated from an area of convection that emerged onto water after sitting over Australia on 23 February. The interaction with a monsoon trough formed an area of low pressure that developed into Tropical Cyclone Graham on 27 February. The storm moved slowly to the east-southeast, and after turning to the south it peaked as a tropical storm and made landfall on Western Australia the next day. The cyclone weakened as it moved inland, and dissipated on 1 March. The storm dropped heavy rainfall and caused high winds, which produced flooding and downed trees. One fatality occurred, though no significant damages were reported. Meteorological history On 23 February 2003, an area of convection that was situated over land for roughly a week emerged over open waters along the northern coast of Australia. The strengthening of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Pressure Area
A high-pressure area, high, or anticyclone, is an area near the surface of a planet where the atmospheric pressure is greater than the pressure in the surrounding regions. Highs are middle-scale meteorological features that result from interplays between the relatively larger-scale dynamics of an entire planet's atmospheric circulation. The strongest high-pressure areas result from masses of cold air which spread out from polar regions into cool neighboring regions. These highs weaken once they extend out over warmer bodies of water. Weaker—but more frequently occurring—are high-pressure areas caused by atmospheric subsidence: Air becomes cool enough to precipitate out its water vapor, and large masses of cooler, drier air descend from above. Within high-pressure areas, winds flow from where the pressure is highest, at the center of the area, toward the periphery where the pressure is lower. However, if the planet is rotating, the straight direction of the air flow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyclone Inigo
Cyclone Inigo is tied with Cyclone Gwenda for being the most intense recorded cyclone in the Australian region in terms of pressure, with the possible exception of Cyclone Mahina. Inigo developed from a tropical low that crossed eastern Indonesia in late March 2003. Becoming a named tropical cyclone on 1 April, Inigo rapidly intensified as it tracked southwestward, reaching a minimum central pressure of 900 hPa on 4 April with maximum 1 minute sustained winds of 170mph. An approaching trough weakened the cyclone and turned it to the southeast, and on 8 April, Inigo dissipated after making landfall on Western Australia, as a minimal tropical storm. The precursor disturbance dropped heavy rainfall across eastern Indonesia, causing widespread flooding and mudslides. The worst of the damage was on Flores island, though damage was also reported on West Timor and Sumba. The flooding and mudslides damaged or destroyed thousands of houses, forcing many to leave their homes. A tot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Retired Australian Cyclone Names
Tropical cyclones are non-frontal, low-pressure systems that develop, within an environment of warm sea surface temperatures and little vertical wind shear aloft. Within the Australian region, names are assigned from three pre-determined lists, to such systems, once they reach or exceed ten–minute sustained wind speeds of , near the center, by either the Australian Bureau of Meteorology, Papua New Guinea's National Weather Service or Indonesia's Badan Meteorologi Klimatologi dan Geofisika. Within the Australian region, tropical cyclones have been officially named since the 1963–64 Australian region cyclone season, though several meteorological papers show that a few tropical cyclones were named before 1964–65. The names of significant tropical cyclones that cause a high amount of damage and/or loss of life are retired from the lists of tropical cyclone names by the World Meteorological Organization's RA V Tropical Cyclone Committee at their bi-annual meeting.

Fitzroy Crossing, Western Australia
Fitzroy Crossing is a small town in the Kimberley region of Western Australia, east of Broome and west of Halls Creek. It is approximately from the state capital of Perth. It is above sea level and is situated on a low rise surrounded by the vast floodplains of the Fitzroy River and its tributary Margaret River. At the 2016 census, the population of the Fitzroy Crossing town-site was 1,297; with a further 2,000 or so people living in up to 50 Aboriginal communities scattered throughout the Fitzroy Valley. About 80% of the Fitzroy Valley population were Indigenous Australians with a split of closer to 60/40 (indigenous/non-indigenous) in the townsite. Tourism, cattle stations and mining are the main industries in the area. History Fitzroy Crossing and the lands and valleys around it were the home for a number of Aboriginal language groups. When Fitzroy Crossing was established the main group was the Bunuba people, their land stretching from the present day Brooking Spring ...

Flooding
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting in some of t ...

Sandfire, Western Australia
Sandfire is a location and roadhouse on the Great Northern Highway in Western Australia between Port Hedland and Broome. It is on the western edge of the Great Sandy Desert, and east of Wallal Downs and Mandora Station. It is inland, and located 20 km from the coast in the region of the Mandora Marsh and the Eighty Mile Beach, 45 km north of the Kidson Track turnoff. The area surrounding the roadhouse is of high cultural significance to the Nyangumarta people The Nyangumarta people, also written Njaŋumada, Njangamada, Njanjamarta and other variations, are a nation of Aboriginal Australians from the northwestern coast of Western Australia. According to Norman Tindale, they are divided into two distinc ..., who hold native title over the area. It is only one of three fuel stations (the others being Pardoo and Roebuck roadhouses) in the 610 km between those two towns. In April 2007, the Sandfire Roadhouse was extensively damaged by fire, leaving a $1.5 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eighty Mile Beach
Eighty Mile Beach, also spelled Eighty-mile Beach or 80-mile Beach, lies along the north-west coast of Western Australia about half-way between the towns of Broome, Western Australia, Broome and Port Hedland, Western Australia, Port Hedland. It is a beach some in length, forming the coastline where the Great Sandy Desert approaches the Indian Ocean. It is one of the most important sites for migratory wader, shorebirds, or waders, in Australia, and is recognised as a wetland of international importance under the Ramsar Convention, Ramsar Convention on Wetlands. History Traditional ownership and usage The southern section of Eighty Mile Beach is part of the traditional territory of the Nyangumarta people, who maintain a strong connection to the area with many songs, stories and ceremonies associated with sites along and in the vicinity of the beach. In June 2009 the Federal Court of Australia determined that the Nyangumarta People were the valid native title holders of th ...

Trough (meteorology)
A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft. Near-surface troughs sometimes mark a weather front associated with clouds, showers, and a wind direction shift. Upper-level troughs in the jet stream (as shown in diagram) reflect cyclonic filaments of vorticity. Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there. Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions mark troughs by a line. In the United States, a trough may be marked as a dashed line or bold line. In the UK, Hong Kong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
