Sunny. Would the climate zones be the same if the continents were in the Pangaea shape or is it something different? Antarctica - Antarctica - Climate: The unique weather and climate of Antarctica provide the basis for its familiar appellations—Home of the Blizzard and White Desert. Point your mental compass due South and test the extremes of your knowledge of Antarctica in this quiz. +1°C to -10°C monthly averages; Winter temperatures brought down by sea-ice Low cloud common in summer with rain and sleet, heavy snow in winter If ice shelves break up, the ice flow behind them may accelerate, resulting in increasing melt of the Antarctic ice sheet and an increasing contribution to sea level. Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. Great cyclonic storms circle Antarctica in endless west-to-east procession, exchanging atmospheric heat to the continent from sources in the southern Atlantic, Pacific, and Indian oceans. Lacking a heavy and protective water-vapour-rich atmospheric layer, which in other areas absorbs and reradiates to Earth long-wave radiation, the Antarctic surface readily loses heat energy into space. With few reporting stations, weather prediction has been exceedingly difficult but is now greatly aided by satellite imagery. This process of ozone destruction, which also occurs to a lesser extent in the Arctic, increases the amount of ultraviolet-B radiation reaching Earth’s surface, a type of radiation shown to impair photosynthesis in plants, cause an increase in skin cancer in humans, and damage DNA molecules in living things. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. This one is relatively mild for Antarctica but still involves three days of wind gusting up to 50mph. Ozone depletion over the Antarctic continent was first noticed in 1985. The Arctic Ocean, a climate-ameliorating heat source, has no counterpart at the South Pole, the great elevation and perpetually reflective snow cover of which instead intensify its polar climate. By far the coldest continent, Antarctica has winter temperatures that range from −128.6 °F (−89.2 °C), the world’s lowest recorded temperature, measured at Vostok Station (Russia) on July 21, 1983, on the high inland ice sheet to −76 °F (−60 °C) near sea level. Antarctica is surrounded by a very cold ocean called the Southern Ocean. 1 0 0 0 0. About 75% of the coastline of Antarctica is ice shelf. One of the most unique astrophysical observatories on Earth is AMANDA, the Antarctic Muon and Neutrino Detector Array. This effect is restricted to the 1980s and 1990s. A possible explanation is that loss of UV-absorbing ozone may have cooled the stratosphere and strengthened the polar vortex, a pattern of spinning winds around the South Pole. The coldest temperature ever recorded in Antarctica was at Vostok Station. Adelie penguin . It is considered as the coldest continent on earth. The Antarctic is so cold that even with increases of a few degrees, temperatures would generally remain below the melting point of ice. Severe low temperatures vary with latitude, elevation, and distance from the ocean. Warm Snap Turned Antarctica Green Around the Edges; Thawed-out continent was lined with trees 15 million years ago, study says. [10][11] This temperature is not directly comparable to the –89.2 °C reading quoted above, since it is a skin temperature deduced from satellite-measured upwelling radiance, rather than a thermometer-measured temperature of the air 1.5 m (4.9 ft) above the ground surface. [2][3], A higher temperature of 19.8 °C (67.6 °F) recorded at Signy Research Station on 30 January 1982 was the record for the Antarctic region encompassing all land and ice south of 60° S.[4]. [12][13] A major focus of upper atmospheric research in Antarctica is to understand the processes leading to the annual springtime depletion in stratospheric ozone—the “ozone hole.” Ozone depletion has been steadily increasing since it was first detected in 1977. These clouds are isolated within an atmospheric circulation pattern known as the “polar vortex,” which develops during the long, cold Antarctic winter. Despite the tremendous volume of potential liquid water stored as ice, Antarctica must be considered one of the world’s great deserts; the average precipitation (liquid water equivalent) is only about 2 inches (50 mm) per year over the polar plateau, though considerably more, perhaps 10 times as much, falls in the coastal belt. It is essentially a telescope built within the ice sheet to detect high-energy neutrinos that pass through the Earth from distant sources. Steady westerly winds prevail, reaching gale force at times with their passage through deep Antarctic low-pressure zones. It had been gradually retreating before the breakup event. The continent is also extremely dry (it is technically a desert), averaging 166 mm (6.5 in) of precipitation per year. The chemical reactions take place with the arrival of sunlight in spring and are facilitated by the presence of halogens (chlorine and fluorine), which are mostly products of human activity. The reason for their great climatic difference primarily lies in their reverse distributions of land and sea: the Arctic is an ocean surrounded by land, while Antarctica is a continent surrounded by ocean. (Weather station: McMurdo, Antarctica). International concern is increasing over the possibility of global warming (an amplification of Earth’s greenhouse effect). The highest temperature ever recorded on Antarctica was 20.75 °C (69.3 °F) at Comandante Ferraz Antarctic Station on 9 February 2020, beating the previous record of 18.3 °C (64.9 °F) at Esperanza Base, on the northern tip of the Antarctic Peninsula, on 6 February 2020. Few storms bring snowfalls to interior regions. The weather in Antarctica can be highly variable, and the weather conditions can often change dramatically in short periods of time. [37], There is also evidence for widespread glacier retreat around the Antarctic Peninsula. Robertson Land coast. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. In the South hemisphere this climate zone occupies the all territory of Antarctica and in the North hemisphere occupies the Arctic ocean. The amount of incoming solar radiation, and thus heat, depends additionally on the incident angle of the rays and therefore decreases inversely with latitude to reach a minimum at the geographic poles. The vortex acts like an atmospheric barrier, preventing warmer, coastal air from moving into the continent's interior. The average winter air temperature varies from…. It was -128.6 degree F or -89.2 degree Celsius. Sun & Moon Today ; Sunrise & Sunset ; Moonrise & Moonset ; Moon Phases ; Eclipses ; Night Sky ; Weather Today Weather Hourly 14 Day Forecast Yesterday/Past Weather Climate (Averages) Currently: 24 °F. What are the type of climate in Antarctica? The lowest recorded temperature of any location on Earth's surface at 81°48′S 63°30′E / 81.8°S 63.5°E / -81.8; 63.5 was revised with new data in 2018 in nearly 100 locations, ranging from −93.2 °C (−135.8 °F)[7] to −98 °C (−144.4 °F). The coast is warmer; on the coast Antarctic average temperatures are around −10 °C (14.0 °F) (in the warmest parts of Antarctica) and in the elevated inland they average about −55 °C (−67.0 °F) in Vostok. The majority of ice shelf consists of floating ice, and a lesser amount consists of glaciers that move slowly from the land mass into the sea. Automatic geophysical observatories on the high polar plateau now record information on the polar ionosphere and magnetosphere, providing data that are critical to an understanding of Earth’s response to solar activity. The temperatures are negative all year round. 2001: 3,250 square kilometres (1,250 square miles) of the Larsen B ice shelf disintegrated in February 2001. Melting or breakup of floating shelf ice does not directly affect global sea levels; however, ice shelves have a buttressing effect on the ice flow behind them. Sun & Moon Today ; Sunrise & Sunset ; Moonrise & Moonset ; Moon Phases ; Eclipses ; Night Sky ; Weather Today Weather Hourly 14 Day Forecast Yesterday/Past Weather Climate (Averages) Currently: 20 °F. See more current weather × Annual Weather Averages in McMurdo. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change. Winds on the polar plateau are usually light, with monthly mean velocities at the South Pole ranging from about 9 miles per hour (4 metres per second) in December (summer) to 17 miles per hour (8 metres per second) in June and July (winter). Only a few coastal fringes lie north of the Antarctic Circle. Navigate parenthood with the help of the Raising Curious Learners podcast. [28], The continent-wide average surface temperature trend of Antarctica is positive – that is, the temperature is increasing – and significant at more than 0.05 °C (0.09 °F) per decade since 1957. The Larsen A Ice Shelf disintegrated in 1995, whereas the Larsen B Ice Shelf broke apart in 2002. Sunny. The glaciers and ice sheets of Antarctica may document such change, especially in West Antarctica. Please update this article to reflect recent events or newly available information. He has reindeer to pull his sleigh because reindeer are happy to live in the cold and the snow. Most of this water precipitates as snow along the continental margin. CARA supports a submillimetre-wave telescope, several other telescopes, and a program to measure the properties of relict radiation left over from the big bang—useful in testing cosmological models. Higher temperatures are expected to lead to more precipitation, which takes the form of snow. The polar (arctic) climate zone occupies the ice caps of the planet. (Weather station: McMurdo, Antarctica). If all the land-ice covering Antarctica were to melt — around 30 million cubic kilometres (7.2 million cubic miles) of ice — the seas would rise by over 60 metres (200 feet). During a recent[when?] Map showing the extent of collapse of the Larsen Ice Shelf. McMurdo … [27] Not only are the ice sheets losing mass, they are losing mass at an accelerating rate. African Climate and Development Initiative post-doctoral research fellow Dr Kamoru Abiodun Lawal said that temperatures in Antarctica can range from 10°C in summer to -40°C in winter. The Antarctic Exclusion Zone (AEZ), the red area which can be seen at the bottom of the race tracker, prevents sailors from dipping into dangerous waters where they might put their boats – and themselves – at risk. It also did show that the temperature was very stable throughout the year.[39][40][41][42]. AR5 Climate Change 2013: The Physical Science Basis AR5 Climate Change 2014: Impacts, Adaptation, and Vulnerability AR5 Climate Change 2014: Mitigation of Climate Change Antarctica is in which climate zone? By far the coldest continent, Antarctica has winter temperatures that range from −128.6 °F (−89.2 °C), the world’s lowest recorded temperature, measured at Vostok Station (Russia) on July 21, 1983, on the high inland ice sheet to −76 °F (−60 °C) … It possesses a thick section of pure material (ice) that can be used as a cosmic particle detector. Experts in the field explore key topics, including environmental changes, human colonization and present environmental trends. There are various classifications for describing weather conditions in Antarctica; restrictions given to workers during the different conditions vary by station and nation.[17][18][19]. [citation needed] The Antarctic Peninsula has the most moderate climate. Average winter temperatures on the Antarctic Peninsula have increased by 10.8 °F (6 °C) since 1960, and the disintegration of much of the Larsen Ice Shelf between January 1995 and March 2002 was largely attributed to climatic changes resulting from rising average air temperatures. Monthly means at McMurdo Station range from −26 °C (−14.8 °F) in August to −3 °C (26.6 °F) in January. Does it have mountains? It also noted a need for greater understanding of the role the region may have in slowing the rate of climate change and of the future behaviour of the ice sheet and its contribution to sea level rise. During one winter at Mirny Station, gusts reached more than 110 miles per hour on seven occasions. This turbulent air may appear suddenly and is responsible for the brief and localized Antarctic “blizzards” during which no snow actually falls and skies above are clear. This involves an array of hundreds of optical devices set at depths of up to 1.2 miles (2 km) in the ice below the South Pole. [22] For the contribution of Antarctica to present and future sea level change, see sea level rise. Although “night” theoretically is six months long at the geographic pole, one month of this actually is a twilight period. These and other factors are essentially the same for both polar regions. Because a Worldwide Pattern of climate change, 97% of experts agreeing about what’s happening can not convince the nay sayers. Some of the effects could be due to natural variability, he added. Antarctica, and particularly the South Pole, attracts much interest in astronomical and astrophysical studies as well as research on the interactions between the Sun and the upper atmosphere of Earth. Only at fixed stations operated since the IGY have year-round measurements been made. Throughout the year, it is freezing cold and even die-hard winter athletes should be careful of the crisp temperatures. Theoretically, Antarctica would be located in all time zones; however, areas south of the Antarctic Circle experience extreme day-night cycles near the times of the June and December solstices, making it difficult to determine which time zone would be appropriate.

The highest temperature ever recorded on Antarctica was 20.75 °C (69.3 °F)[1] at Comandante Ferraz Antarctic Station on 9 February 2020, beating the previous record of 18.3 °C (64.9 °F) at Esperanza Base, on the northern tip of the Antarctic Peninsula, on 6 February 2020. Asked by Wiki User. presents two different climatic zones: a relatively mild and humid marine climate on the west coast (windward), where northwesterly winds prevail, and a cooler continental cli- mate on the east coast (leeward) (Fig. Climate: EU programme spots largest ozone hole over Antarctica in years 6 Oct, 2020 07:05 PM 2 minutes to read A lonely penguin appears in Antarctica during the summer season. The spot, which is located in the heart of the West Antarctic Ice Sheet, is one of the fastest-warming places on Earth. ¹The total ice volume is different from the sum of the component parts because individual figures have been rounded. Antarctica is the coldest continent on Earth. In Antarctica it is cold throughout the year with temperatures of -30 in winter and about -10 to 10 in summer. If you have gone to Antarctica, you can tell how cold the temperature in the continent is. When Santa leaves the North Pole, he has to bundle up. At the South Pole, the highest temperature ever recorded was −12.3 °C (9.9 °F) on 25 December 2011. East Antarctica is colder than West Antarctica because of its higher elevation. 1) mainly affected by southerly winds (King and Turner, 2009). A stronger polar vortex might explain the cooling trend in the interior of Antarctica. The previous record for the entire Antarctic region - which includes the continent, islands and ocean that are in the Antarctic climatic zone - was 19.8C, logged in January 1982. On midwinter day, about June 21, the Sun’s rays reach to only 23.5° (not exact, because of refraction) from the South Pole along the latitude of 66.5° S, a line familiarly known as the Antarctic Circle.
