Indian Ocean Dipole
The Indian Ocean Dipole (IOD), 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 Ocean—which 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 1997–98, with another in 2006. T ...

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. How ...

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, 2013 and 2015. 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 unders ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
2019–20 Australian Bushfire Season
The 201920 Australian bushfire season commenced with serious uncontrolled fires in June 2019. , fires this season have burned an estimated , destroyed over 5,900 buildings (including 2,779 homes) and killed at least 34 people. An estimated one billion animals were killed and some endangered species may be driven to extinction. Air quality has dropped to hazardous levels. The cost of dealing with the bushfires is expected to exceed the $4.4 billion of the 2009 Black Saturday fires, and tourism sector revenues have fallen more than $1 billion. By 7 January 2020, the smoke had moved approximately across the South Pacific Ocean to Chile and Argentina. As of 2 January 2020, NASA estimated that of CO had been emitted. From September 2019 fires heavily impacted various regions of the state of New South Wales. In eastern and north-eastern Victoria large areas of forest burnt out of control for four weeks before the fires emerged from the forests in late December. Multiple s ...

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 tropical cyclone, South-West Indian Ocean basin. In the Southern Hemisphere, which includes the Australian region tropical cyclone, Australian, South Pacific tropical cyclone, South Pacific, and South Atlantic tropical cyclone, 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. Idai is also the second costliest tropical cyclone in the South-West Indian Ocean basin, behind Cyclone Chido of 2024. The tenth named storm, seventh tropical cyclone, and seventh ...

University Of Aizu
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in the ...

Climate Change
Present-day climate change includes both global warming—the ongoing increase in Global surface temperature, global average temperature—and its wider effects on Earth's climate system. Climate variability and change, Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is Scientific consensus on climate change, driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, Deforestation and climate change, deforestation, and some Greenhouse gas emissions from agriculture, agricultural and Environmental impact of concrete, industrial practices release greenhouse gases. These gases greenhouse effect, absorb some of the heat that the Earth Thermal radiation, radiates after it warms from sunlight, warming the lower atmosphere.

Timor Sea
The Timor Sea (, , or ) is a relatively shallow sea in the Indian Ocean bounded to the north by the island of Timor with Timor-Leste to the north, Indonesia to the northwest, Arafura Sea to the east, and to the south by Australia. The Sunda Trench marks the deepest point of the Timor Sea with a depth of more than 3300 metres, separating the continents of Oceania in the southeast and Asia to the northwest and north. The Timor sea is prone to earthquakes and tsunamis north of the Sunda Trench, due to its location on the Ring of Fire as well as volcanic activity and can experience major cyclones, due to the proximity from the Equator. 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 Montara oil spill, oil spill for 25 years in 2009. It is possible that Australia's first inhabitants cros ...
