Indian Ocean Dipole
The Indian Ocean Dipole (IOD), also known as the Indian NiΓ±o, is an irregular oscillation of sea surface temperatures in which the western Indian Ocean becomes alternately warmer (positive phase) and then colder (negative phase) than the eastern part of the ocean. Phenomenon The IOD involves an aperiodic oscillation of sea-surface temperatures (SST), between "positive", "neutral" and "negative" phases. A positive phase sees greater-than-average sea-surface temperatures and greater precipitation in the western Indian Ocean region, with a corresponding cooling of waters in the eastern Indian Oceanβwhich tends to cause droughts in adjacent land areas of Indonesia and Australia. The negative phase of the IOD brings about the opposite conditions, with warmer water and greater precipitation in the eastern Indian Ocean, and cooler and drier conditions in the west. The IOD also affects the strength of monsoons over the Indian subcontinent. A significant positive IOD occurred in 1997β ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subtropical Indian Ocean Dipole
The Subtropical Indian Ocean Dipole (SIOD) is featured by the oscillation of sea surface temperatures (SST) in which the southwest Indian Ocean i.e. south of Madagascar is warmer and then colder than the eastern part i.e. off Australia.Behera SK, Yamagata T. 2001Subtropical SST dipole events in the southern Indian Ocean Geophysical Research Letters 28: 327β330. It was first identified in the studies of the relationship between the SST anomaly and the south-central Africa rainfall anomaly; the existence of such a dipole was identified from both observational studies and model simulations . The phenomenon Positive phase of Subtropical Indian Ocean Dipole is characterized by warmer-than-normal sea surface temperature in the southwestern part, south of Madagascar, and colder-than-normal sea surface temperature off Australia, causing above-than-normal precipitation in many regions over south and central Africa. Stronger winds prevail along the eastern edge of the subtropical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Dipole Anomaly
The Arctic dipole anomaly is a pressure pattern characterized by high pressure on the arctic regions of North America and low pressure on those of Eurasia. This pattern sometimes replaces the Arctic oscillation and the North Atlantic oscillation. It was observed for the first time in the first decade of 2000s and is perhaps linked to recent climate change. The Arctic dipole lets more southern winds into the Arctic Ocean resulting in more ice melting. The summer 2007 event played an important role in the record low sea ice extent which was recorded in September. The Arctic dipole has also been linked to changes in arctic circulation patterns that cause drier winters in Northern Europe, but much wetter winters in Southern Europe and colder winters in East Asia, Europe and the eastern half of North America. Description In the 1990s and early 2000s, many studies of Arctic sea ice export focused on the Arctic and North Atlantic oscillations as the primary drivers of export. Howev ...

2020 Jakarta Floods
Flash floods occurred throughout the Indonesian capital of Jakarta and its metropolitan area on the early hours of 1 January 2020, due to the overnight rain which dumped nearly of rainwater, causing the Ciliwung and Cisadane rivers to overflow. At least 66 people have been killed, and 60,000 displaced in the worst flooding in the area since 2007. Background Floods have hit Jakarta several times in the past, including in 1621, 1654, 1918, 1942, 1976, 1996, 2002, 2007 and 2013. A significant contributing factor is that a substantial part of Jakarta is low-lying; some 24,000 ha (240 km2) of the main part of Jakarta are below sea level. Flooding can become severe if heavy rain coincides with high tides. When this happens, the high tides push water into low-lying areas coinciding with the runoff from rains in upland areas (such as Bogor) flowing down into the Jakarta area. Uncontrolled population growth in urban areas, poor land-use planning, and the lack of understanding ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2019β20 Australian Bushfire Season
The 201920 Australian bushfire season (Black Summer), was a period of bushfires in many parts of Australia, which, due to its unusual intensity, size, duration, and uncontrollable dimension, is considered a megafire. The Australian National University reported that the area burned in 2019/2020 was "well below average" due to low fuel levels and fire activity in unpopulated parts of Northern Australia, but that "Despite low fire activity overall, vast forest fires occurred in southeast Australia from southeast Queensland to Kangaroo Island." In June 2019 the Queensland Fire and Emergency Service acting director warned of the potential for an early start to the bushfire season which normally starts in August. The warning was based on the Northern Australia bushfire seasonal outlook noting exceptional dry conditions and a lack of soil moisture, combined with early fires in central Queensland. Throughout the summer, hundreds of fires burnt, mainly in the southeast of the country ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2019β20 South-West Indian Ocean Cyclone Season
The 2019β20 South-West Indian Ocean cyclone season was a slightly above-average season in tropical cyclone and subtropical cyclone formation west of 90Β°E. The season officially began on 15 November, however, the formation of the first system—Zone of Disturbed Weather 01—occurred on 22 July 2019, well before the official start of the season. This was the earliest start to a season since the 2016β17 season. The season then officially ended on 30 April 2020, with the exception of Mauritius and the Seychelles, for which it officially ended on 15 May 2020. These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of longitude, 90Β°E and south of the Equator. Tropical and subtropical cyclones in this basin are monitored by the Regional Specialized Meteorological Centre in RΓ©union. For the second consecutive year in a row, the first system formed before the official start of the season. After ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Idai
Intense Tropical Cyclone Idai () was one of the worst tropical cyclones on record to affect Africa and the Southern Hemisphere. The long-lived storm caused catastrophic damage, and a humanitarian crisis in Mozambique, Zimbabwe, and Malawi, leaving more than 1,500 people dead and many more missing. Idai is the deadliest tropical cyclone recorded in the South-West Indian Ocean basin. In the Southern Hemisphere, which includes the Australian, South Pacific, and South Atlantic basins, Idai ranks as the second-deadliest tropical cyclone on record. The only system with a higher death toll is the 1973 Flores cyclone that killed 1,650 off the coast of Indonesia. The tenth named storm, seventh tropical cyclone, and seventh intense tropical cyclone of the 2018β19 South-West Indian Ocean cyclone season, Idai originated from a tropical depression that formed off the east coast of Mozambique on 4 March. The storm, Tropical Depression 11, made landfall in Mozambique later in the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Timor Sea
The Timor Sea ( id, Laut Timor, pt, Mar de Timor, tet, Tasi Mane or ) is a relatively shallow sea bounded to the north by the island of Timor, to the east by the Arafura Sea, and to the south by Australia. The sea contains a number of reefs, uninhabited islands and significant hydrocarbon reserves. International disputes emerged after the reserves were discovered resulting in the signing of the Timor Sea Treaty. The Timor Sea was hit by the worst oil spill for 25 years in 2009. It is possible that Australia's first inhabitants crossed the Timor Sea from the Malay Archipelago at a time when sea levels were lower. Etymology The Timor Sea is named after Timor, the island on the other side of the sea's northern coastline. The island's name is a variant of , Malay for "east". In Tetum, the expression () is often used to refer to the Timor Sea. The counterpart of that body of water, the ' Ombai-Wetar Strait', which has smaller waves, is less turbid, and washes most of Timor ...
