21-716: The river flows north of the Arctic Circle , in the northern limits of the Central Siberian Plateau and the North Siberian Lowland . The area is lonely and desolate, devoid of settlements. The Beyenchime -Udzha interfluve is an area where diamonds are found. The Udya is the third largest tributary of the Anabar. Its sources are in the vicinity of the sources of the Bur , Buolkalakh and

42-524: Is visible at local midnight , and at least once the centre is not visible at local noon . Directly on the Arctic Circle these events occur, in principle, exactly once per year: at the June and December solstices , respectively. However, because of atmospheric refraction and mirages , and also because the sun appears as a disk and not a point, part of the midnight sun is visible, on the night of

63-713: Is seen as summer's beginning. In Sweden , midsummer is one of the year's major holidays when the country closes down as much as during Christmas. The following tables contain information on the length of the day on 20 June 2016, close to the summer solstice of the Northern Hemisphere and winter solstice of the Southern Hemisphere . The data was collected from the website of the Finnish Meteorological Institute as well as from certain other websites. The data

84-489: Is seen as the beginning of summer. On the summer solstice, Earth's maximum axial tilt toward the Sun is 23.44°. Likewise, the Sun's declination from the celestial equator is 23.44°. Although the summer solstice is the longest day of the year for that hemisphere, the dates of earliest sunrise and latest sunset vary by a few days. This is because Earth orbits the Sun in an ellipse, and its orbital speed varies slightly during

105-431: Is the day with the longest period of daylight and shortest night of the year in that hemisphere, when the sun is at its highest position in the sky. At either pole there is continuous daylight at the time of its summer solstice. The opposite event is the winter solstice . The summer solstice occurs during the hemisphere's summer . In the Northern Hemisphere , this is the June solstice (20, 21 or 22 June) and in

126-461: Is the longest day of the year), the Sun will not set. These phenomena are referred to as polar night and midnight sun respectively, and the further north one progresses, the more pronounced these effects become. For example, in the Russian port city of Murmansk , three degrees above the Arctic Circle, the Sun does not rise above the horizon for 40 successive days in midwinter. The position of

147-608: The Arctic Ocean , the Scandinavian Peninsula , North Asia , Northern America , and Greenland. The land within the Arctic Circle is divided among eight countries: Norway, Sweden, Finland, Russia, the United States ( Alaska ), Canada ( Yukon , Northwest Territories , and Nunavut ), Denmark (Greenland), and Iceland (where it passes through the small offshore island of Grímsey ). The climate north of

168-615: The Beyenchime of the Olenyok basin. It is formed at the confluence of rivers Tokur-Udya and Mas-Udya in an area of lakes. It heads roughly northwestwards all along its course. Finally it joins the right bank of the Anabar 242 km (150 mi) from its mouth. The confluence is not far upstream from Saskylakh . The river is fed by rain and snow. It is frozen between early October and late May / early June. The longest tributaries are

189-506: The Greek word ἀρκτικός ( arktikos : "near the Bear , northern") and that from the word ἄρκτος ( arktos : " bear "). The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the centre of the Sun can remain continuously above or below the horizon for twenty-four hours; as a result, at least once each year at any location within the Arctic Circle the centre of the Sun

210-479: The Roman Empire , the traditional date of the summer solstice was 24 June. In Germanic-speaking cultures, the time around the summer solstice is called ' midsummer '. Traditionally in northern Europe midsummer was reckoned as the night of 23–24 June, with summer beginning on May Day . The summer solstice continues to be seen as the middle of summer in many European cultures, but in some cultures or calendars it

231-478: The Southern Hemisphere , this is the December solstice (20, 21, 22 or 23 of December). Since prehistory, the summer solstice has been a significant time of year in many cultures, and has been marked by festivals and rituals. Traditionally, in temperate regions (especially Europe), the summer solstice is seen as the middle of summer and referred to as midsummer ; although today in some countries and calendars it

252-406: The 129 kilometres (80 mi) long Chyuyompe-Yurege (Чюёмпэ-Юрэгэ) and the 104 kilometres (65 mi) long Udyakan (Удьакан) from the right, as well as the 168 kilometres (104 mi) long Chymaara (Чымаара) from the left. The Udya river is rich in fish species, including broad whitefish , humpback whitefish and peled , among others. Arctic Circle The Arctic Circle is one of

273-526: The Arctic Circle is generally cold, but the coastal areas of Norway have a generally mild climate as a result of the Gulf Stream , which makes the ports of northern Norway and northwest Russia ice-free all year long. In the interior, summers can be quite warm, while winters are extremely cold. For example, summer temperatures in Norilsk , Russia will sometimes reach as high as 30 °C (86 °F), while

294-589: The Arctic Circle is not fixed and currently runs 66°33′50.2″ north of the Equator . Its latitude depends on the Earth's axial tilt , which fluctuates within a margin of more than 2° over a 41,000-year period, owing to tidal forces resulting from the orbit of the Moon . Consequently, the Arctic Circle is currently drifting northwards at a speed of about 14.5 m (48 ft) per year. The word arctic comes from

315-604: The Arctic Circle with about 5,000 inhabitants. The largest such community in Canada is Inuvik in the Northwest Territories , with 3,137 inhabitants. Download coordinates as: The Arctic Circle is roughly 16,000 km (9,900 mi) in circumference. The area north of the Circle is about 20,000,000 km (7,700,000 sq mi) and covers roughly 4% of Earth's surface. The Arctic Circle passes through

336-466: The Arctic Circle, lying 6 km (4 mi) south of the line. Salekhard (51,186) in Russia is the only city in the world located directly on the Arctic Circle. In contrast, the largest North American community north of the Arctic Circle, Sisimiut ( Greenland ), has approximately 5,600 inhabitants. In the United States, Utqiagvik, Alaska (formerly known as Barrow) is the largest settlement north of

357-411: The northern summer solstice , at a latitude of about 50 minutes of arc (′) (90 km (56 mi)) south of the Arctic Circle. Similarly, on the day of the northern winter solstice , part of the Sun may be seen up to about 50′ north of the Arctic Circle. That is true at sea level ; those limits increase with elevation above sea level , although in mountainous regions there is often no direct view of

378-516: The true horizon. The largest communities north of the Arctic Circle are situated in Russia, Norway, and Sweden: Murmansk (population 295,374) and Norilsk (178,018) in Russia; Tromsø (75,638) in Norway, Vorkuta (58,133) in Russia, Bodø (52,357) and Harstad (24,703) in Norway; and Kiruna , Sweden (22,841). Rovaniemi (62,667) in Finland is the largest settlement in the immediate vicinity of

399-620: The two polar circles , and the most northerly of the five major circles of latitude as shown on maps of Earth at about 66° 34' N. Its southern equivalent is the Antarctic Circle . The Arctic Circle marks the southernmost latitude at which, on the winter solstice (which is the shortest day of the year) in the Northern Hemisphere , the Sun will not rise all day, and on the Northern Hemisphere's summer solstice (which

420-412: The winter temperatures frequently fall below −50 °C (−58 °F). Starting at the prime meridian and heading eastwards, the Arctic Circle passes through: Summer solstice The summer solstice or estival solstice occurs when one of Earth 's poles has its maximum tilt toward the Sun . It happens twice yearly, once in each hemisphere ( Northern and Southern ). The summer solstice

441-733: The year. There is evidence that the summer solstice has been culturally important since the Neolithic era. Many ancient monuments in Europe especially, as well as parts of the Middle East, Asia and the Americas, are aligned with the sunrise or sunset on the summer solstice (see archaeoastronomy ). The significance of the summer solstice has varied among cultures, but most recognize the event in some way with holidays , festivals , and rituals around that time with themes of fertility. In
