1988–89 Australian Region Cyclone Season
The 1988–89 Australian region cyclone season was a slightly above average tropical cyclone season. It officially started on 1 November 1988, and officially ended on 30 April 1989. The regional tropical cyclone operational plan defines a "tropical cyclone year" separately from a "tropical cyclone season"; the "tropical cyclone year" began on 1 July 1988 and ended on 30 June 1989.

Cyclone Orson
Severe Tropical Cyclone Orson was the fourth most intense cyclone ever recorded in the Australian region. Forming out of a tropical low on 17 April 1989, Orson gradually intensified as it tracked towards the west. After attaining Category 5 intensity on 20 April, the storm began to track southward and accelerated. The following day, the cyclone reached its peak intensity with winds of (10-minute sustained) and a barometric pressure of 904 hPa (mbar). Orson maintained this intensity for nearly two days before making landfall near Dampier. The cyclone rapidly weakened after landfall as it accelerated to the southeast. After moving into the Great Australian Bight on 24 April, the storm dissipated. Despite Orson's extreme intensity, damage was relatively minimal as it struck a sparsely populated region of Western Australia. Five people were killed offshore and damages amounted to (). The storm damaged a new gas platform, delaying the project for nearly two weeks. The most se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Caledonia
New Caledonia ( ; ) is a group of islands in the southwest Pacific Ocean, southwest of Vanuatu and east of Australia. Located from Metropolitan France, it forms a Overseas France#Sui generis collectivity, ''sui generis'' collectivity of the French Republic, a legal status unique in overseas France, and is enshrined in a dedicated chapter of the French Constitution. The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre (New Caledonia), Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines (New Caledonia), Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. French people, especially locals, call Grande Terre , a nickname also used more generally for the entire New Caledonia. Kanak people#Agitation for independence, Pro-independence Kanak parties use the name (''pron.'' ) to refer to New Caledonia, a term coined in the 1980s from the ethnic name of the indi ...

Barometric Pressure
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1,013.25 millibars, 760 mm Hg, 29.9212 inchesHg, or 14.696 psi.International Civil Aviation Organization. ''Manual of the ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Low
A tropical cyclone is a rapidly rotating storm system with a low-pressure area, 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 called a 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. A typhoon is the same thing which occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of or more. Tropical cyclones typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water from the ocean ...

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.

Pontoon (boat)
A pleasure boat with two lengthwise pontoons A pontoon boat is a flattish boat that relies on floats to remain buoyant. These pontoons (also called ''tubes'') contain much reserve buoyancy and allow designers to create large deck plans fitted with a variety of accommodations including expansive lounge areas, stand-up bars, and sun pads. More horsepower is now able to be applied to the stern due to design improvements. Pontoon boat drafts may be as shallow as , which reduces risk of running aground and underwater damage; this allows it to come close to shore to pick up and drop off loads. History A pontoon ferry crossing the Zambezi at Kazungula The 1952 invention of the pontoon motorboat in the United States is credited to a farmer who lived on the Horseshoe Chain of Lakes, near Richmond, Minnesota. Ambrose Weeres put a wooden platform on two columns of steel barrels welded together end-to-end, creating a sturdy deck that would be more stable on a lake than a conventional b ...

Rottnest Island
Rottnest Island (), often colloquially referred to as "Rotto", is a Islands of Perth, Western Australia, island off the coast of Western Australia, located west of Fremantle. A sandy, low-lying island formed on a base of aeolianite limestone, Rottnest is an A-class reserve, the highest level of protection afforded to Crown land#Australia, public land. Together with Garden Island (Western Australia), Garden Island, Rottnest Island is a remnant of Pleistocene dune ridges. Along with several other islands, Rottnest became separated from the mainland when sea levels rose around 7,000 years ago. The traditional Noongar name for the island is , which means "place across the water where the spirits are". Human artefacts have been found on the island dating back at least 30,000 years, but visitation and habitation of the island by the Noongar people appears to have ceased following its separation from the mainland.
