2014–15 Australian Region Cyclone Season
The 2014–15 Australian region cyclone season was a slightly below average tropical cyclone season. The season officially ran from 1 November 2014, to 30 April 2015, however, a tropical cyclone could form at any time between 1 July 2014, and 30 June 2015, and would count towards the season total. During the season, tropical cyclones were officially monitored, by one of the five Tropical Cyclone Warning Centres (TCWCs) that are operated in this region. Three of the five centres are operated by the Australian Bureau of Meteorology (BoM) in Perth, Darwin, and Brisbane, while the other two are operated by the National Weather Service of Papua New Guinea in Port Moresby and the Indonesian Agency for Meteorology, Climatology and Geophysics in Jakarta, Indonesia. The United States Joint Typhoon Warning Center (JTWC) and other national meteorological services, including Météo-France, also monitored the basin during the season. __TOC__ Seasonal forecasts Ahead of the cyclone se ...

Cyclone Marcia
Severe Tropical Cyclone Marcia was a powerful tropical cyclone that made landfall at its peak strength over central Queensland, near Shoalwater Bay on 20 February 2015. The cyclone went on to affect various areas including Yeppoon and Rockhampton. It passed just to the west of Yeppoon as a Category 4 system, then traversed over the regional city of Rockhampton as a Category 2 system on the same day. Eventually, the cyclone weakened, moved southeast out to sea, before dissipating. Marcia caused at least A$750 million (US$587 million) worth of damage. Meteorological history The Australian Bureau of Meteorology (BoM) started to monitor a tropical low which developed within the monsoon trough to the southeast of Papua New Guinea on 15 February. The system drifted generally eastwards and developed slowly under moderate vertical wind shear, until the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert early on 17 February when deep convection wrappi ...

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 ro ...

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 List of country subdivisions by area, second-largest country subdivision in the world, surpassed only by Russia's Sakha, Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the South-West Land Division, 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 pe ...

Kimberley (Western Australia)
The Kimberley is the northernmost of the nine regions of Western Australia. It is bordered on the west by the Indian Ocean, on the north by the Timor Sea, on the south by the Great Sandy and Tanami deserts in the region of the Pilbara, and on the east by the Northern Territory. The region was named in 1879 by government surveyor Alexander Forrest after Secretary of State for the Colonies John Wodehouse, 1st Earl of Kimberley. History The Kimberley was one of the earliest settled parts of Australia, with the first humans landing about 65,000 years ago. They created a complex culture that developed over thousands of years. Yam (''Dioscorea hastifolia'') agriculture was developed, and rock art suggests that this was where some of the earliest boomerangs were invented. The worship of Wandjina deities was most common in this region, and a complex theology dealing with the transmigration of souls was part of the local people's religious philosophy. In 1837, with expedition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wyndham, Western Australia
Wyndham is the northernmost town in the Kimberley region of Western Australia, on the Great Northern Highway, northeast of Perth. It was established in 1886 to service a new goldfield at Halls Creek, and it is now a port and service centre for the east Kimberley with a population of 941 as of the 2021 census. Aboriginal and Torres Strait Islander people make up 54% of the population. Wyndham comprises two areas - the original town site at Wyndham Port situated on Cambridge Gulf, and by road to the south, the Three Mile area with the residential and shopping area for the port, also founded in 1886. Wyndham is part of the Shire of Wyndham-East Kimberley. History Wyndham is within traditional Doolboong country. The first European to visit the area was Phillip Parker King in 1819. He was instructed to find a river 'likely to lead to an interior navigation into the great continent'. He sailed into Cambridge Gulf, which he named after the Duke of Cambridge, and then sailed up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monsoon Trough
The monsoon trough is a portion of the Intertropical Convergence Zone in the Western Pacific,Bin WangThe Asian Monsoon.Retrieved 2008-05-03. as depicted by a line on a weather map showing the locations of minimum sea level pressure, and as such, is a convergence zone between the wind patterns of the southern and northern hemispheres. Westerly monsoon winds lie in its equatorward portion while easterly trade winds exist poleward of the trough. Right along its axis, heavy rains can be found which usher in the peak of a location's respective rainy season. As it passes poleward of a location, hot and dry conditions develop. The monsoon trough plays a role in creating many of the world's rainforests. The term ''monsoon trough'' is most commonly used in monsoonal regions of the Western Pacific such as Asia and Australia. The migration of the ITCZ/monsoon trough into a landmass heralds the beginning of the annual rainy season during summer months. Depressions and tropical cyclones ofte ...

Eyewall Replacement Cycle
In meteorology, eyewall replacement cycles, also called concentric eyewall cycles, naturally occur in intense tropical cyclones, generally with winds greater than , or major hurricanes ( Category 3 or above). When tropical cyclones reach this intensity, and the eyewall contracts or is already sufficiently small, some of the outer rainbands may strengthen and organize into a ring of thunderstorms—a new, outer eyewall—that slowly moves inward and robs the original, inner eyewall of its needed moisture and angular momentum. Since the strongest winds are in a tropical cyclone's eyewall, the storm usually weakens during this phase, as the inner wall is "choked" by the outer wall. Eventually the outer eyewall replaces the inner one completely, and the storm may re-intensify. The discovery of this process was partially responsible for the end of the U.S. government's hurricane modification experiment Project Stormfury. This project set out to seed clouds outside the eyewall, appa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eye (cyclone)
The eye is a region of mostly calm weather at the center of tropical cyclones. The eye of a storm is a roughly circular area, typically in diameter. It is surrounded by the ''eyewall'', a ring of towering thunderstorms where the most severe weather and highest winds occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is the location of the storm's minimum barometric pressure—where the atmospheric p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2014–15 South-West Indian Ocean Cyclone Season
The 2014–15 South-West Indian Ocean cyclone season was an above average event in tropical cyclone formation. It began on November 15, 2014, and ended on April 30, 2015, with the exception for Mauritius and the Seychelles, for which it ended on May 15, 2015. These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of 90°E and south of the Equator. Tropical and subtropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion. __TOC__ Seasonal summary ImageSize = width:800 height:200 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns:3 left:30 top:58 columnwidth:250 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/11/2014 till:30/04/2015 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/11/2014 Colors = id:canvas value:gray(0.88) id:GP value:red id:ZD v ...
