Vladimir Alexandrov
Vladimir Valentinovich Alexandrov (; born 1938; disappeared 1985) was a Soviet/Russian physicist who created a mathematical model for the nuclear winter theory. He disappeared while at the Second International Conference of Nuclear Free Zones Local Authorities in Cordoba, Spain on 31 March and his ultimate fate remains unknown, though speculation continues.Revkin, Andrew (1986). "A Cold War Climate Mystery Endures: the Vanishing of Vladimir Alexandrov", '' Science Digest'', July 1986. p38. One of his last papers was ''Man and Biosphere'' published in 1985; it is said to have charted the moving trend in the science of nuclear winter. It was co-authored with Nikita Moiseyev and A. M. Tarko. When questioned by journalists in 1986, his acquaintances in Madrid gave differing accounts of how much he resisted when being driven towards the Soviet embassy. In 2016 Andrew Revkin said, "He's almost assuredly dead. ...This wasn't just, you know, thumb-sucking climate science. It was in th ...

Pamyat Parizhskoy Kommuny
Pamyat Parizhskoy Kommuny () is a settlement in the Bor urban okrug of the Nizhny Novgorod Oblast. Geography A settlement on the left bank of the Volga, 51 km below the Bor, Nizhny Novgorod Oblast, Bor city, where a shipyard is located. On February 1, 1932, the village at the backwater “Pamyat Parizhskoy Kommuny” of the Rabotkinsky district was transformed into a workers' settlement, leaving its former name. Until 2004, the town had the status of an urban-type settlement. History The first mention of the village dates back to 1869. In the same year, the lands of the Zhukovsky backwater were purchased by the merchant Ivan Milyutin for one and a half thousand silver rubles. The first workshops providing repair of ships appeared. In 1886, the active development of the town began: the construction of the first houses for the purpose of permanent housing. In 1917-1918 the ships were nationalized. During the civil war, when military operations were going on on the Volga, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climatology
Climatology (from Greek , ''klima'', "slope"; and , '' -logia'') or climate science is the scientific study of Earth's climate, typically defined as weather conditions averaged over a period of at least 30 years. Climate concerns the atmospheric condition during an extended to indefinite period of time; weather is the condition of the atmosphere during a relative brief period of time. The main topics of research are the study of climate variability, mechanisms of climate changes and modern climate change. This topic of study is regarded as part of the atmospheric sciences and a subdivision of physical geography, which is one of the Earth sciences. Climatology includes some aspects of oceanography and biogeochemistry. The main methods employed by climatologists are the analysis of observations and modelling of the physical processes that determine climate. Short term weather forecasting can be interpreted in terms of knowledge of longer-term phenomena of climate, for insta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vladimir Kryuchkov
Vladimir Aleksandrovich Kryuchkov (; 29 February 1924 – 23 November 2007) was a Soviet lawyer, diplomat, and head of the KGB, member of the Politburo of the Central Committee of the CPSU. Initially working in the Soviet justice system as a prosecutor's assistant, Kryuchkov then graduated from the Diplomatic Academy of the Soviet Foreign Ministry and became a diplomat. During his years in the foreign service, he met Yuri Andropov, who became his main patron. From 1974 until 1988, Kryuchkov headed the foreign intelligence branch of the KGB, the First Chief Directorate (PGU). During these years, the Directorate was involved in funding and supporting various communist, socialist, and anti-colonial movements across the world, some of which came to power in their countries and established pro-Soviet governments; in addition, under Kryuchkov's leadership the Directorate had major triumphs in penetrating Western intelligence agencies, acquiring valuable scientific and technica ...

Mitrokhin Archive
The Mitrokhin Archive refers to a collection of handwritten notes about secret KGB operations spanning the period between the 1930s and 1980s made by KGB archivist Vasili Mitrokhin which he shared with British intelligence in the early 1990s. Mitrokhin, who had worked at KGB headquarters in Moscow from 1956 to 1985, first offered his material to the US's Central Intelligence Agency (CIA) in Latvia, but they rejected it as possible fakes. After that, he turned to the UK's MI6, which arranged his defection from Russia. Mitrokhin secretly made his handwritten notes by copying archival documents in the period between 1972 and 1984, when he supervised the move of the archive of KGB's foreign intelligence department First Chief Directorate from the Lubyanka Building to their new headquarters at Yasenevo District, Yasenevo. When he defected to the United Kingdom in 1992, he brought the archive with him, in six full trunks. His defection was not officially announced until 1999. The offic ...

Nuclear War
Nuclear warfare, also known as atomic warfare, is a War, military conflict or prepared Policy, political strategy that deploys nuclear weaponry. Nuclear weapons are Weapon of mass destruction, weapons of mass destruction; in contrast to conventional warfare, nuclear warfare can produce destruction in a much shorter time and can have a long-lasting radiological warfare, radiological result. A major nuclear exchange would likely have long-term effects, primarily from the Nuclear fallout, fallout released, and could also lead to secondary effects, such as "nuclear winter", nuclear famine, and societal collapse. A global thermonuclear war with Cold War-era stockpiles, or even with the current smaller stockpiles, may lead to various scenarios including human extinction. To date, the only use of nuclear weapons in armed conflict occurred in 1945 with the American atomic bombings of Hiroshima and Nagasaki. On August 6, 1945, a uranium Nuclear weapon design, gun-type device (code name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baroclinicity
In fluid dynamics, the baroclinity (often called baroclinicity) of a stratified fluid is a measure of how misaligned the gradient of pressure is from the gradient of density in a fluid. In meteorology, a baroclinic flow is one in which the density depends on both temperature and pressure (the fully general case). A simpler case, barotropic flow, allows for density dependence only on pressure, so that the curl of the pressure-gradient force vanishes. Baroclinity is proportional to: :\nabla p \times \nabla \rho which is proportional to the sine of the angle between surfaces of constant pressure and surfaces of constant density. Thus, in a ''barotropic'' fluid (which is defined by zero baroclinity), these surfaces are parallel. In Earth's atmosphere, barotropic flow is a better approximation in the tropics, where density surfaces and pressure surfaces are both nearly level, whereas in higher latitudes the flow is more baroclinic. These midlatitude belts of high atmospheric b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Climate Model
A general circulation model (GCM) is a type of climate model. It employs a mathematical model of the general circulation of a planetary atmosphere or ocean. It uses the Navier–Stokes equations on a rotating sphere with thermodynamics, thermodynamic terms for various energy sources (radiation, latent heat). These equations are the basis for computer programs used to simulation, simulate the Earth's atmosphere or oceans. Atmospheric and oceanic GCMs (AGCM and Ocean general circulation model, OGCM) are key components along with sea ice and Land, land-surface components. GCMs and global climate models are used for weather forecasting, understanding the climate, and forecasting climate change. Atmospheric GCMs (AGCMs) model the atmosphere and impose sea surface temperatures as boundary conditions. Coupled atmosphere-ocean GCMs (AOGCMs, e.g. HadCM3, EdGCM, GFDL CM2.X, ARPEGE-Climat) combine the two models. The first general circulation climate model that combined both oceanic and a ...

Cray-1
The Cray-1 was a supercomputer designed, manufactured and marketed by Cray Research. Announced in 1975, the first Cray-1 system was installed at Los Alamos National Laboratory in 1976. Eventually, eighty Cray-1s were sold, making it one of the most successful supercomputers in history. It is perhaps best known for its unique shape, a relatively small C-shaped cabinet with a ring of benches around the outside covering the power supplies and the cooling system. The Cray-1 was the first supercomputer to successfully implement the vector processor design. These systems improve the performance of math operations by arranging memory and registers to quickly perform a single operation on a large set of data. Previous systems like the CDC STAR-100 and ASC had implemented these concepts but did so in a way that seriously limited their performance. The Cray-1 addressed these problems and produced a machine that ran several times faster than any similar design. The Cray-1's architect ...
