Ragnar Fjørtoft
Ragnar Fjørtoft (1 August 1913 – 28 May 1998) was an internationally recognized Norwegian meteorologist. He was part of a Princeton, New Jersey team that in 1950 performed the first successful numerical weather prediction using the ENIAC electronic computer. He was also a professor of meteorology at the University of Copenhagen and director of the Norwegian Meteorological Institute. Biography Ragnar Fjørtoft was born in Kristiania to the deaf teacher Lauritz Hansen Fjørtoft (1877–1941) and his wife Anne Birgitte Marie Schultze (1881–??). The family eventually moved to Trondheim, where Fjørtoft took his examen artium in 1933. He thereupon moved to Oslo to study natural science, with meteorology as specialization. His teacher was Halvor Solberg, who earlier had been a student of Vilhelm Bjerknes. On 29 March 1939, Fjørtoft married Ragnhild Nordskog (1918–). In the same year, he moved to Bergen, where he became a meteorologist at the Forecasting Division of Western ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oslo
Oslo ( , , or ; sma, Oslove) is the capital and most populous city of Norway. It constitutes both a county and a municipality. The municipality of Oslo had a population of in 2022, while the city's greater urban area had a population of in 2019, and the metropolitan area had an estimated population of in 2021. During the Viking Age the area was part of Viken. Oslo was founded as a city at the end of the Viking Age in 1040 under the name Ánslo, and established as a ''kaupstad'' or trading place in 1048 by Harald Hardrada. The city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 reduced its influence. After being destroyed by a fire in 1624, during the reign of King Christian IV, a new city was built closer to Akershus Fortress and named Christiania in honour of the king. It became a municipality ('' formannskapsdistrikt'') on 1 January 1838. The city fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norwegian Meteorological Institute
The Norwegian Meteorological Institute ( no, Meteorologisk institutt), also known internationally as MET Norway, is Norway's national meteorological institute. It provides weather forecasts for civilian and military uses and conducts research in meteorology, oceanography and climatology. It is headquartered in Oslo and has offices and stations in other cities and places. It has around 500 full-time staff and was founded in 1866. History The institute was founded on 1 December 1866 with the help of Norwegian astronomer and meteorologist Henrik Mohn who served as its director until 1913. He is credited with founding meteorological research in Norway. The abbreviation ''MET Oslo'' or ''MET OSLO'' has been used internationally for a long time; the World Meteorological Organization for example recommended in 1956 that its members standardized references to this institute as ''MET OSLO''.Abridged Final Report of the Session, Commission for Marine Meteorology, Secretariat of the World ...

Atmospheric Wave
An atmospheric wave is a periodic disturbance in the fields of atmospheric variables (like surface pressure or geopotential height, temperature, or wind velocity) which may either propagate (''traveling wave'') or not (''standing wave''). Atmospheric waves range in spatial and temporal scale from large-scale planetary waves (Rossby waves) to minute sound waves. Atmospheric waves with periods which are harmonics of 1 solar day (e.g. 24 hours, 12 hours, 8 hours... etc.) are known as atmospheric tides. Causes and effects The mechanism for the forcing of the wave, for example, the generation of the initial or prolonged disturbance in the atmospheric variables, can vary. Generally, waves are either excited by heating or dynamic effects, for example the obstruction of the flow by mountain ranges like the Rocky Mountains in the U.S. or the Alps in Europe. Heating effects can be small-scale (like the generation of gravity waves by convection) or large-scale (the formation of Rossby w ...

Doctor Philosophiae (Danish And Norwegian Degree)
A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin: or ') is the most common degree at the highest academic level awarded following a course of study. PhDs are awarded for programs across the whole breadth of academic fields. Because it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a dissertation, and defend their work before a panel of other experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title ''Doctor'' (often abbreviated "Dr" or "Dr.") with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society. Those who teach at universities or work in academic, educa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vortex
In fluid dynamics, a vortex ( : vortices or vortexes) is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved. Vortices form in stirred fluids, and may be observed in smoke rings, whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone, tornado or dust devil. Vortices are a major component of turbulent flow. The distribution of velocity, vorticity (the curl of the flow velocity), as well as the concept of circulation are used to characterise vortices. In most vortices, the fluid flow velocity is greatest next to its axis and decreases in inverse proportion to the distance from the axis. In the absence of external forces, viscous friction within the fluid tends to organise the flow into a collection of irrotational vortices, possibly superimposed to larger-scale flows, including larger-scale vortices. Once formed, vortices can move, stretch, twist, and interact in complex ways. A moving vortex carries s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mot Dag
Mot Dag (, 'Towards Day') was a Norwegian political group. The group was active from the 1920s to the early 1930s and was first affiliated with the Labour Party. After World War II, many of its former members were leaders in Norwegian politics and cultural activities. History and profile It was established in 1921 under the initiative of Erling Falk (1887–1940), partly with origins in the debate forum in the Social Democratic Student Association () at the University of Oslo; partly from a Falk-led study circle which, from 1919, involved Viggo Hansteen, Axel Sømme, and Arnold Hazeland. Members were strongly linked to Falk's personality and were subject to strict discipline. Falk aimed to develop a body of students and young workers committed to revolutionary socialism: according to George Lakey, the group "sought to replace middle-class individualism with a collective and disciplined spirit". The magazine ''Mot Dag'' was published by the group between 1921 and 1936. The first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Left-wing
Left-wing politics describes the range of political ideologies that support and seek to achieve social equality and egalitarianism, often in opposition to social hierarchy. Left-wing politics typically involve a concern for those in society whom its adherents perceive as disadvantaged relative to others as well as a belief that there are unjustified inequalities that need to be reduced or abolished. Left-wing politics are also associated with popular or state control of major political and economic institutions. According to emeritus professor of economics Barry Clark, left-wing supporters "claim that human development flourishes when individuals engage in cooperative, mutually respectful relations that can thrive only when excessive differences in status, power, and wealth are eliminated." Within the left–right political spectrum, ''Left'' and ''Right'' were coined during the French Revolution, referring to the seating arrangement in the French Estates General. Those ...

Bergen
Bergen (), historically Bjørgvin, is a city and municipality in Vestland county on the west coast of Norway. , its population is roughly 285,900. Bergen is the second-largest city in Norway. The municipality covers and is on the peninsula of Bergenshalvøyen. The city centre and northern neighbourhoods are on Byfjorden, 'the city fjord', and the city is surrounded by mountains; Bergen is known as the "city of seven mountains". Many of the extra-municipal suburbs are on islands. Bergen is the administrative centre of Vestland county. The city consists of eight boroughs: Arna, Bergenhus, Fana, Fyllingsdalen, Laksevåg, Ytrebygda, Årstad, and Åsane. Trading in Bergen may have started as early as the 1020s. According to tradition, the city was founded in 1070 by King Olav Kyrre and was named Bjørgvin, 'the green meadow among the mountains'. It served as Norway's capital in the 13th century, and from the end of the 13th century became a bureau city of the Hanseatic Leag ...

Meteorology
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water.
