Amderma
Amderma (russian: Амдерма, lit. ''a walrus rookery'' in Nenets) is a rural locality (a settlement) in Zapolyarny District of Nenets Autonomous Okrug, Russia, located on the coast of Kara Sea, near the Vaygach Island, from Naryan-Mar, the administrative center of the autonomous okrug. Population: . History It was established in 1933. Previously an urban-type settlement, it was demoted to a rural locality in November 2005, but its rural status was not officially codified until a law to that effect was passed in April 2015. Climate Amderma has a polar climate ( ET) with very cool and short summers combined with very long and cold (but by Russian standards not severe) winters. Although relative winter temperatures are normally hovering around , the transition months of May and October see a milder form of winter. As a result of the lack of regular warm temperatures Amderma is above the tree line. It experiences midnight sun and polar night. However, the cold Arctic Ocean ...

Amderma Airport
Amderma Airport is a former interceptor base in Arctic Russia, near Novaya Zemlya, located 4 km west of Amderma (Амдерма). It is a simple airfield built on a spit along the ocean, with some tarmac space. The facility's prime purpose was to defend the northern approaches to European Russia. Amderma's significance was driven home during the Cold War years when on 1 June 1960 a MiG-19 from Amderma shot down a Boeing RB-47H that was crossing Cape Kanin Nos. Since the 1960s, the airfield has been home to the 72 Gv IAP (72 Guards Interceptor Aviation Regiment) of the 10th OA PVO, which was operating at least 31 MiG-31 aircraft during the 1991-94 period. Tupolev Tu-128 and MiG-19 were stationed here in the 1960s. Airlines and destinations Nordavia used to operate twice-monthly flights to Arkhangelsk via Naryan-Mar using Antonov An-24 The Antonov An-24 ( Russian/ Ukrainian: Антонов Ан-24) (NATO reporting name: Coke) is a 44-seat twin turboprop transport/p ...

Nenets Autonomous Okrug
The Nenets Autonomous Okrug (russian: Не́нецкий автоно́мный о́круг; Nenets: Ненёцие автономной ӈокрук, ''Nenjocije awtonomnoj ŋokruk'') is a federal subject of Russia and an autonomous okrug of Arkhangelsk Oblast. Its administrative center is the town of Naryan-Mar. It has an area of and a population of 42,090 as of the 2010 Census, making it the least populous federal subject. A plan to merge the autonomous okrug with Arkhangelsk Oblast was presented by the governors of both federal subjects on 13 May 2020, with a referendum planned for September, but was met with opposition by locals, leading to the merger process being scrapped completely. Geography The arctic ecology of this area has a number of unique features derived from the extreme temperatures and unique geologic province. Polar bears are found in this locale; in fact, the sub-population found here is a genetically distinct taxon associated with the Barents ...

Populated Places Of Arctic Russia
Population typically refers to the number of people in a single area, whether it be a city or town, region, country, continent, or the world. Governments typically quantify the size of the resident population within their jurisdiction using a census, a process of collecting, analysing, compiling, and publishing data regarding a population. Perspectives of various disciplines Social sciences In sociology and population geography, population refers to a group of human beings with some predefined criterion in common, such as location, race, ethnicity, nationality, or religion. Demography is a social science which entails the statistical study of populations. Ecology In ecology, a population is a group of organisms of the same species who inhabit the same particular geographical area and are capable of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with ...

Rural Localities In Nenets Autonomous Okrug
In general, a rural area or a countryside is a geographic area that is located outside towns and cities. Typical rural areas have a low population density and small settlements. Agricultural areas and areas with forestry typically are described as rural. Different countries have varying definitions of ''rural'' for statistical and administrative purposes. In rural areas, because of their unique economic and social dynamics, and relationship to land-based industry such as agriculture, forestry and resource extraction, the economics are very different from cities and can be subject to boom and bust cycles and vulnerability to extreme weather or natural disasters, such as droughts. These dynamics alongside larger economic forces encouraging to urbanization have led to significant demographic declines, called rural flight, where economic incentives encourage younger populations to go to cities for education and access to jobs, leaving older, less educated and less wealthy populat ...

Fluorite
Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 4 as fluorite. Pure fluorite is colourless and transparent, both in visible and ultraviolet light, but impurities usually make it a colorful mineral and the stone has ornamental and lapidary uses. Industrially, fluorite is used as a flux for smelting, and in the production of certain glasses and enamels. The purest grades of fluorite are a source of fluoride for hydrofluoric acid manufacture, which is the intermediate source of most fluorine-containing fine chemicals. Optically clear transparent fluorite lenses have low dispersion, so lenses made from it exhibit less chromatic aberration, making them valuable in microscopes and telescopes. Fluorite optics are al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polar Night
The polar night is a phenomenon where the nighttime lasts for more than 24 hours that occurs in the northernmost and southernmost regions of Earth. This occurs only inside the polar circles. The opposite phenomenon, the polar day, or midnight sun, occurs when the Sun remains above the horizon for more than 24 hours. "Night" is understood as the center of the Sun being below a free horizon. Since the atmosphere refracts sunlight, the polar day is longer than the polar night, and the area that is affected by polar night is somewhat smaller than the area of midnight sun. The polar circle is located at a latitude between these two areas, at approximately 66.5°. While it is day in the Arctic Circle, it is night in the Antarctic Circle, and vice versa. Any planet or moon with a sufficient axial tilt that rotates with respect to its star significantly more frequently than it orbits the star (no tidal locking between the two) will experience the same phenomenon (a nightt ...

Midnight Sun
The midnight sun is a natural phenomenon that occurs in the summer months in places north of the Arctic Circle or south of the Antarctic Circle, when the Sun remains visible at the local midnight. When the midnight sun is seen in the Arctic, the Sun appears to move from left to right, but in Antarctica the equivalent apparent motion is from right to left. This occurs at latitudes from 65°44' to 90° north or south, and does not stop exactly at the Arctic Circle or the Antarctic Circle, due to refraction. The opposite phenomenon, polar night, occurs in winter, when the Sun stays below the horizon throughout the day. Details Around the summer solstice (approximately 21 June in the Northern Hemisphere and 21 December in the Southern Hemisphere), in certain areas the Sun does not set below the horizon within a 24-hour period. Geography Because there are no permanent human settlements south of the Antarctic Circle, apart from research stations, the countries and terri ...

Tree Line
The tree line is the edge of the habitat at which trees are capable of growing. It is found at high elevations and high latitudes. Beyond the tree line, trees cannot tolerate the environmental conditions (usually cold temperatures, extreme snowpack, or associated lack of available moisture). The tree line is sometimes distinguished from a lower timberline, which is the line below which trees form a forest with a closed canopy. At the tree line, tree growth is often sparse, stunted, and deformed by wind and cold. This is sometimes known as '' krummholz'' (German for "crooked wood"). The tree line often appears well-defined, but it can be a more gradual transition. Trees grow shorter and often at lower densities as they approach the tree line, above which they are unable to grow at all. Given a certain latitude, the tree line is approximately 300 to 1000 meters below the permanent snow line and roughly parallel to it. Causes Due to their vertical structure, trees are more sus ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polar Climate
The polar climate regions are characterized by a lack of warm summers but with varying winters. Every month in a polar climate has an average temperature of less than . Regions with polar climate cover more than 20% of the Earth's area. Most of these regions are far from the equator and near the poles, and in this case, winter days are extremely short and summer days are extremely long (could last for the entirety of each season or longer). A polar climate consists of cool summers and very cold winters, which results in treeless tundra, glaciers, or a permanent or semi-permanent layer of ice. It is identified with the letter E in the Köppen climate classification. Subtypes There are two types of polar climate: ET, or tundra climate; and EF, or ice cap climate. A tundra climate is characterized by having at least one month whose average temperature is above , while an ice cap climate has no months averaging above . In a tundra climate, even coniferous trees cannot grow, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autonomous Okrugs Of Russia
Autonomous okrugs ( rus, автономный округ, ''avtonomnyy okrug''; more correctly referred to as "autonomous districts" or "autonomous areas") are a type of federal subject of the Russian Federation and simultaneously an administrative division type of some federal subjects. As of 2014, Russia has four autonomous okrugs of its 85 federal subjects. The Chukotka Autonomous Okrug is the only okrug which is not subordinate to an oblast. The other three are Arkhangelsk Oblast's Nenets Autonomous Okrug, and Tyumen Oblast's Yamalo-Nenets Autonomous Okrug and Khanty-Mansi Autonomous Okrug. According to the constitution of the USSR, autonomous republics, autonomous oblasts and autonomous okrugs had the right, by means of a referendum, to independently resolve the issue of staying in the USSR or in the seceding union republic, as well as to raise the issue of their state-legal status. History Originally called national okrug, this type of administrative unit was created in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
