Medicane Daniel
Storm Daniel, also known as Cyclone Daniel, was a catastrophic tropical cyclone that became the deadliest Mediterranean tropical-like cyclone in recorded history, as well as one of the costliest tropical cyclones on record outside of the North Atlantic Basin. Forming as a low-pressure system around 4 September 2023, the storm affected Greece, Bulgaria, and Turkey with extensive flooding. The storm then organized as a Mediterranean low and was designated as ''Storm Daniel.'' It soon acquired quasi-tropical characteristics and moved toward the coast of Libya, where it caused catastrophic flooding caused by the collapse of two dams, Derna and Mansour, resulting in the flooding of the Wadi Derna river causing catastrophic damage to the city of Derna. After collapsing the two dams, Storm Daniel degenerated into a remnant low. The storm was the result of an omega block; a high-pressure zone sandwiched between two zones of low pressure, with the isobars shaping like the Greek ...

Contour Line
A contour line (also isoline, isopleth, isoquant or isarithm) of a Function of several real variables, function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a cross-section (geometry)#Definition, plane section of the graph of a function of two variables, three-dimensional graph of the function f(x,y) parallel to the (x,y)-plane. More generally, a contour line for a function of two variables is a curve connecting points where the function has the same particular value. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines. The gradient of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yale University
Yale University is a Private university, private Ivy League research university in New Haven, Connecticut, United States. Founded in 1701, Yale is the List of Colonial Colleges, third-oldest institution of higher education in the United States, and one of the nine colonial colleges chartered before the American Revolution. Yale was established as the Collegiate School in 1701 by Congregationalism in the United States, Congregationalist clergy of the Connecticut Colony. Originally restricted to instructing ministers in theology and sacred languages, the school's curriculum expanded, incorporating humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first Doctor of Philosophy, PhD in the United States in 1861 and organizing as a university in 1887. Yale's faculty and student populations grew rapidly after 1890 due to the expansion of the physical campus and its scientif ...

Bulgarian National Radio
Bulgarian National Radio (, ''Bǎlgarsko nacionalno radio''; abbreviated to БНР, BNR) is Bulgaria's national radio broadcasting organisation. It operates two national channels and nine regional channels, as well as an international service ( Radio Bulgaria) which broadcasts in 11 languages. History Until World War II Listening to radio broadcasts from other countries having become popular in Bulgaria by the late 1920s, a group of engineers and intellectuals founded ''Rodno Radio'' ("Native, or Homeland, Radio") on 30 March 1930 with the aim of providing Sofia with its own radio station. Broadcasting began in June of the same year. ''Rodno Radio'' was renamed ''Radio Sofija'' in 1934. On 25 January 1935, Boris III of Bulgaria signed a Decree nationalising ''Rodno Radio'' and making all broadcasting in Bulgaria a state-organised activity. In early 1936, a new and more powerful medium-wave transmitter sited near Sofia was joined by additional transmitting stations at Stara Zagor ...

Cold-core Low
A cold-core low, also known as an upper level low or cold-core cyclone, is a cyclone aloft which has an associated cold pool of air residing at high altitude within the Earth's troposphere, without a frontal structure. It is a low pressure system that strengthens with height in accordance with the thermal wind relationship. If a weak surface circulation forms in response to such a feature at subtropical latitudes of the eastern north Pacific or north Indian oceans, it is called a subtropical cyclone. Cloud cover and rainfall mainly occurs with these systems during the day. Severe weather, such as tornadoes, can occur near the center of cold-core lows. Cold lows can help spawn cyclones with significant weather impacts, such as polar lows, and Kármán vortices. Cold lows can lead directly to the development of tropical cyclones, owing to their associated cold pool of air aloft or by acting as additional outflow channels to aid in further development. Characteristics Cold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Warming
Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, deforestation, and some agricultural and industrial practices release greenhouse gases. These gases absorb some of the heat that the Earth radiates after it warms from sunlight, warming the lower atmosphere. Carbon dioxide, the primary gas driving global warming, has increased in concentration by about 50% since the pre-industrial era to levels not seen for millions of years. Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and Wildfire#Climate change effects, wildfires are becoming more common. polar ampl ...

Benghazi
Benghazi () () is the List of cities in Libya, second-most-populous city in Libya as well as the largest city in Cyrenaica, with an estimated population of 859,000 in 2023. Located on the Gulf of Sidra in the Mediterranean Sea, Mediterranean, Benghazi is also a major seaport. A Greeks, Greek colony named History of Benghazi, Euesperides had existed in the area from around 525 BC. In the 3rd century BC, it was relocated and refounded as the Ptolemaic Kingdom, Ptolemaic city of Berenice. Berenice prospered under the Romans, and after the 3rd century AD it superseded Cyrene, Libya, Cyrene and Barca (ancient city), Barca as the centre of Cyrenaica. The city went into decline during the Byzantine Empire, Byzantine period and had already been reduced to a small town before Muslim conquest of Egypt, its conquest by the Arabs. After around four centuries of peaceful Ottoman Tripolitania, Ottoman rule, in 1911, Kingdom of Italy, Italy captured Benghazi and the rest of Ottoman Tripolitania, ...

Mediterranean Cyclone
Mediterranean tropical-like cyclones, often referred to as Mediterranean cyclones or Mediterranean hurricanes, and shortened as medicanes, are meteorological phenomena occasionally observed over the Mediterranean Sea. On a few rare occasions, some storms have been observed reaching the strength of a Saffir–Simpson scale#Category 1, Category 1 hurricane on the Saffir–Simpson scale, and Medicane Ianos in 2020 was recorded reaching Saffir–Simpson scale#Category 2, Category 2 intensity. The main societal hazard posed by medicanes is not usually from destructive winds, but through life-threatening torrential rains and flash floods. The occurrence of medicanes has been described as not particularly rare. Tropical-like systems were first identified in the Mediterranean basin in the 1980s, when widespread weather satellite, satellite coverage showing tropical-looking low pressures which formed a eye (cyclone), cyclonic eye in the center were identified. Due to the dry nature of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
