Barrow Island (Western Australia)
Barrow Island is a island northwest off the Pilbara coast of Western Australia. The island is the second largest in Western Australia after Dirk Hartog Island. Early history and European discovery The island was visited by Indigenous Australians approximately 4,000 or more years ago. It separated from the mainland approximately 6,800 years ago. Stone artefacts including several weathered flakes and fragments made of igneous and metamorphic rocks and chert were collected from Barrow Island in the 1960s. Thevenard Island also has evidence of Aboriginal visitation, and it is likely that the nearby Montebello Islands were utilized as well; however, there have been no archaeological finds from these islands. Navigators had noted its existence since the early 17th century, and Nicholas Baudin sighted it in 1803, mistakenly believing it to be part of mainland Australia. Phillip Parker King named the island in 1816 after Sir John Barrow, a Secretary of the Admiralty and founder of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Seroja
Severe Tropical Cyclone Seroja was a deadly tropical cyclone that brought historic flooding and landslides to portions of southern Indonesia and East Timor and later went on to make landfall in Western Australia's Mid West region, becoming the first to do so since Cyclone Elaine in 1999. The twenty-second tropical low, seventh tropical cyclone, and third severe tropical cyclone of the 2020–21 Australian region cyclone season, the precursor of Seroja formed off the south coast of Timor island as Tropical Low 22U at 18:00 UTC on 3 April 2021. The tropical low moved very slowly near the island, while the system's thunderstorms increased in organization. The low intensified into Tropical Cyclone Seroja by 4 April, while it was passing north of Rote Island, while continuing its slow strengthening trend. Due to the presence of Tropical Cyclone Odette in Seroja's vicinity, interaction was anticipated as the storm moved away from Indonesia and East Timor. Its intensity fluctuat ...

Tropical Cyclones In 2015

The most intense storm of the year was Hurricane Patricia, with maximum 10-minute sustained wind speeds of and a minimum pressure of . The deadliest tropical cyclone was Cyclone Komen, which caused 280 fatalities in Southeast India, while the costliest was Typhoon Mujigae, which caused an estimated $4.25 billion USD in damage after striking China. So far, forty Category 3 tropical cyclones formed, including nine Category 5 tropical cyclones in the year.

Cyclone Iggy (2012)
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 ...
