The southern third of Greenland protrudes into the North-Atlantic storm track, a region frequently influenced by cyclones. National and commercial expeditions continued to expand the detail on maps of the Arctic through the eighteenth century, but largely neglected other scientific observations. This map was made in the 1970s, and the extent of sea ice has decreased since then (see below), but this still gives a reasonable overview. The most widely used definition, the area north of the Arctic Circle, where the sun does not set on the June Solstice, is used in astronomical and some geographical contexts. Much of the winter variability in this region is due to clouds. Annual precipitation totals in the Canadian Archipelago increase dramatically from north to south. Climatically, Greenland is divided into two very separate regions: the coastal region, much of which is ice free, and the inland ice sheet. Wind speed units can be changed in the preferences (top right). During the 46-year period when weather records were kept on Shemya Island, in the southern Bering Sea, the average temperature of the coldest month (February) was −0.6 °C (30.9 °F) and that of the warmest month (August) was 9.7 °C (49.5 °F); temperatures never dropped below −17 °C (1 °F) or rose above 18 °C (64 °F); Western Regional Climate Center). [5] Precipitation is frequent in winter, with measurable totals falling on an average of 20 days each January in the Norwegian Sea (USSR 1985). Almost all of the energy available to the Earth's surface and atmosphere comes from the sun in the form of solar radiation (light from the sun, including invisible ultraviolet and infrared light). Coastal areas can be affected by nearby open water, or by heat transfer through sea ice from the ocean, and many parts lose their snow cover in summer, allowing them to absorb more solar radiation and warm more than the interior. Hot days and cold nights (dashed red and blue lines) show the average of the hottest day and coldest night of each month of the last 30 years. Civilian scientific research on the ground has certainly continued in the Arctic, and it is getting a boost from 2007 to 2009 as nations around the world increase spending on polar research as part of the third International Polar Year. This expedition also provided valuable insight into the circulation of the ice surface of the Arctic Ocean. Furthermore, most of the small amount of solar radiation that reaches the surface is reflected away by the bright snow cover. At its maximum extent, in March, sea ice covers about 15 million km² (5.8 million sq mi) of the Northern Hemisphere, nearly as much area as the largest country, Russia.[8]. The North Atlantic Current moderates Svalbard's temperatures, particularly during winter, giving it up to 20 °C higher winter temperature than … For comparison, annual precipitation averaged over the whole planet is about 1,000 mm (39 in); see Precipitation). The number of days with measurable precipitation (more than 0.1 mm [0.004 in] in a day) is slightly greater in July than in January (USSR 1985). The Soviet Union was also interested in the Arctic and established a significant presence there by continuing the North-Pole drifting stations. The result is winter temperatures that are lower than anywhere else in the Arctic, with average January temperatures of −45 to −30 °C (−49 to −22 °F), depending on location and on which data set is viewed. Winter temperatures average below freezing over all of the Arctic except for small regions in the southern Norwegian and Bering Seas, which remain ice free throughout the winter. [2]. Most regions receive less than 500 mm (20 in) annually (Serreze and Hurst 2000, USSR 1985). In the interior, temperatures are kept from rising much above freezing because of the snow-covered surface but can drop to −30 °C (−22 °F) even in July. Differences in surface albedo due for example to presence or absence of snow and ice strongly affect the fraction of the solar radiation reaching the surface that is reflected rather than absorbed. This record was lengthened in the early 1990s when two deeper cores were taken from near the center of the Greenland Ice Sheet. For locations and events which require very high precision (such as energy generation, insurance, etc. These factors result in a negligible input of solar energy to the Arctic in winter; the only things keeping the Arctic from continuously cooling all winter are the transport of warmer air and ocean water into the Arctic from the south and the transfer of heat from the subsurface land and ocean (both of which gain heat in summer and release it in winter) to the surface and atmosphere. There is a large amount of variability in climate across the Arctic, but all regions experience extremes of solar radiation in both summer and winter. However, this region is not part of the Arctic because its continental climate also allows it to have warm summers, with an average July temperature of 15 °C (59 °F). The Bering Sea is influenced by the North Pacific storm track, and has annual precipitation totals between 400 and 800 mm (16 and 31 in), also with a winter maximum. Likewise the United States and Canadian governments cut back on spending for Arctic observing as the perceived need for the DEWLINE declined. What’s become clear in the 15 iterations of the report is nothing will be the same for centuries to come and the shifts are happening faster than anticipated. All variables are measured at relatively few stations in the Arctic, but precipitation observations are made more uncertain due to the difficulty in catching in a gauge all of the snow that falls. The typical pattern of ice motion is shown on the map at right. NOAA’s annual Arctic Report Card, released on Tuesday, Dec. 8, 2020, shows how warming temperatures in the Arctic are transforming the region’s geography and ecosystems.DAVID GOLDMAN / … The northern islands receive similar amounts, with a similar annual cycle, to the central Arctic Basin. Since there is no sunlight, the thermal radiation emitted by the atmosphere is one of this region's main sources of energy in winter. Coastal regions on the northern half of Greenland experience winter temperatures similar to or slightly warmer than the Canadian Archipelago, with average January temperatures of −30 to −25 °C (−22 to −13 °F). In the station-climatology figure above, the plots for Point Barrow, Tiksi, Murmansk, and Isfjord are typical of land areas adjacent to seas that are ice-covered seasonally. It also experiences the longest period without sunlight of any part of the Arctic, and the longest period of continuous sunlight, though the frequent cloudiness in summer reduces the importance of this solar radiation. Particularly the eastern part of Svalbard sees relatively little precipitation annually. Some parts of the Arctic are covered by ice (sea ice, glacial ice, or snow) year-round, and nearly all parts of the Arctic experience long periods with some form of ice on the surface. Modern researchers in the Arctic also benefit from computer models. These data became available after the Cold War, and have provided evidence of thinning of the Arctic sea ice. In winter, the Canadian Archipelago experiences temperatures similar to those in the Arctic Basin, but in the summer months of June to August, the presence of so much land in this region allows it to warm more than the ice-covered Arctic Basin. The meteoblue smartphone APP received an honourable mention by WMO, the World Meteorological Organisation. This caused Fridtjof Nansen to realize that the sea ice was moving from the Siberian side of the Arctic to the Atlantic side. Minimum temperatures in this region in winter are around −50 °C (−58 °F). The coast of the Arctic has a different climate, with drier, colder weather in winter. The end of the Soviet Union in 1991 led to a dramatic decrease in regular observations from the Arctic. These regions receive many weakening cyclones from the North-Atlantic storm track, which is most active in winter. On the June solstice 36% more solar radiation reaches the top of the atmosphere over the course of the day at the North Pole than at the Equator. Arctic sea ice decline: faster than forecasted. The rest of the seas have ice cover for some part of the winter and spring, but lose that ice during the summer. The climate is severe, and temperature varies from 3° to -8° F (-16° to -22° C) in winter to 36° to 44° F (2° to 7° C) in summer. Maximum wind speeds in the Atlantic region can approach 50 m/s (180 km/h (110 mph) in winter.[9]. In most of the Arctic the significant snow melt begins in late May or sometime in June. Annual precipitation amounts given below for Greenland are from Figure 6.5 in Serreze and Barry (2005). The main exception to this general description is the high part of the Greenland Ice Sheet, which receives all of its precipitation as snow, in all seasons. The Chukchi, Laptev, and Kara Seas and Baffin Bay receive somewhat more precipitation than the Arctic Basin, with annual totals between 200 and 400 mm (7.9 and 15.7 in); annual cycles in the Chukchi and Laptev Seas and Baffin Bay are similar to those in the Arctic Basin, with more precipitation falling in summer than in winter, while the Kara Sea has a smaller annual cycle due to enhanced winter precipitation caused by cyclones from the North Atlantic storm track.[5][6]. Changes in the Arctic have global implications. In the decades that followed submarines regularly roamed under the Arctic sea ice, collecting sonar observations of the ice thickness and extent as they went. These maps were made with data from the NCEP/NCAR Reanalysis, which incorporates available data into a computer model to create a consistent global data set. [15][16] However, during the last 100 years temperatures have been rising, despite the fact that the continued changes in earth's orbit would have driven further cooling. For the second day in a row, the archipelago registered 21.2 degrees Celsius (70.2 Fahrenheit) in the afternoon, just under the 21.3 degrees recorded in … Due to the scarcity of long-term weather records in Greenland, especially in the interior, this precipitation climatology was developed by analyzing the annual layers in the snow to determine annual snow accumulation (in liquid equivalent) and was modified on the coast with a model to account for the effects of the terrain on precipitation amounts. NOAA's North Pole Web Cams having been tracking the Arctic summer sea ice transitions through spring thaw, summer melt ponds, and autumn freeze-up since the first webcam was deployed in 2002–present. The interior of the central and northern Greenland Ice Sheet is the driest part of the Arctic. The Arctic Basin is one of the driest parts of the Arctic. During these two years thousands of scientists from over 60 nations will co-operate to carry out over 200 projects to learn about physical, biological, and social aspects of the Arctic and Antarctic (IPY). There are several reasons to expect that climate changes, from whatever cause, may be enhanced in the Arctic, relative to the mid-latitudes and tropics. By July and August, most of the land is bare and absorbs more than 80% of the sun's energy that reaches the surface. Smaller regions of the Arctic Basin just north of Svalbard and the Taymyr Peninsula receive up to about 400 mm (16 in) per year (Serreze and Hurst 2000). Il partage ses frontières avec les Etats-Un This period of setting sun also roughly corresponds to summer in the Arctic. In a recent commentary published in the journal Science, they report that the northern edge of the Canadian Arctic archipelago and Greenland is where the world’s oldest and thickest ice is found. The observations that are available show that precipitation amounts vary by about a factor of 10 across the Arctic, with some parts of the Arctic Basin and Canadian Archipelago receiving less than 150 mm (5.9 in) of precipitation annually, and parts of southeast Greenland receiving over 1,200 mm (47 in) annually. The west coast of the central third of Greenland is also influenced by some cyclones and orographic lift, and precipitation totals over the ice sheet slope near this coast are up to 600 mm (24 in) per year. [15][16] These orbital changes led to a cold period known as the little ice age during the 17th, 18th and 19th centuries. As the amount of solar radiation available to the surface rapidly decreases, the temperatures follow suit. These frequent cyclones lead to larger annual precipitation totals than over most of the Arctic. The result is annual precipitation totals of 400 mm (16 in) over the southern interior to over 1,200 mm (47 in) near the southern and southeastern coasts. However, the high elevation, and corresponding lower temperatures, help keep the bright snow from melting, limiting the warming effect of all this solar radiation. Meteorological observations were collected from the ship during its crossing from September 1893 to August 1896. Greenland: The interior of Greenland differs from the rest of the Arctic. The Arctic Basin is typically covered by sea ice year round, which strongly influences its summer temperatures. Svalbard weather. Every model is assigned one colour that is used in all diagrams. During these early months of Northern Hemisphere spring most of the Arctic is still experiencing winter conditions, but with the addition of sunlight. For vacation planning, you can expect the mean temperatures, and be prepared for hotter and colder days. Auyuittuq National Park is home to iconic mountains Today's satellite instruments provide routine views of not only cloud, snow, and sea-ice conditions in the Arctic, but also of other, perhaps less-expected, variables, including surface and atmospheric temperatures, atmospheric moisture content, winds, and ozone concentration. An earlier climatology of temperatures in the Arctic, based entirely on available data, is shown in this map from the CIA Polar Regions Atlas.[3]. Another interesting use of models has been to use them, along with historical data, to produce a best estimate of the weather conditions over the entire globe during the last 50 years, filling in regions where no observations were made (ECMWF). In addition, the glaciers of the archipelago are already retreating and thinning, some quite rapidly. As with the rest of the planet, the climate in the Arctic has changed throughout time. This is due to the region's continental climate, far from the moderating influence of the ocean, and to the valleys in the region that can trap cold, dense air and create strong temperature inversions, where the temperature increases, rather than decreases, with height. The Canadian Arctic has a unique geography making up 55% of the countries land mass and 67% of the country’s coastline. In summer, the presence of the nearby water keeps coastal areas from warming as much as they might otherwise. The Labrador, Norwegian, Greenland, and Barents Seas and Denmark and Davis Straits are strongly influenced by the cyclones in the North Atlantic storm track, which is most active in winter. There are different definitions of the Arctic. These regions are slightly warmer than the Archipelago because of their closer proximity to areas of thin, first-year sea ice cover or to open ocean in the Baffin Bay and Greenland Sea. Note: Simulated precipitation amounts in tropical regions and complex terrain tend to be lower than local measurements. The meteoblue climate diagrams are based on 30 years of hourly weather model simulations and available for every place on Earth. As such, the climate of much of the Arctic is moderated by the ocean water, which can never have a temperature below −2 °C (28 °F). The climate of the Arctic also depends on the amount of sunlight reaching the surface, and being absorbed by the surface. Expeditions from the 1760s to the middle of the 19th century were also led astray by attempts to sail north because of the belief by many at the time that the ocean surrounding the North Pole was ice-free. This data can be used under the Creative Commons license "Attribution + Non-commercial (BY-NC)". At the North Pole on the June solstice, around 21 June, the sun circles at 23.5° above the horizon. Beginning in the 1850s regular meteorological observations became more common in many countries, and the British navy implemented a system of detailed observation. These reanalysis datasets help compensate for the lack of observations over the Arctic. The period between October 2019 and September 2020 was the second-hottest year in the last century for the Arctic, with surface temperatures 1.9 … An essentially ice-free Arctic may be a reality in the month of September, anywhere from 2050 to 2100.[4]. The IPCC also indicate that, over the last 100 years, the annually averaged temperature in the Arctic has increased by almost twice as much as the global mean temperature has. The models, though imperfect, often provide valuable insight into climate-related questions that cannot be tested in the real world. The only ice remaining from that during the summer minimum, however, would be in the waters around the Canadian Arctic Archipelago, and along the Alaskan and Greenland shorelines. The map shows the 10-year average (2000–2009) global mean temperature anomaly relative to the 1951–1980 mean. Serreze, Mark C. and Roger Graham Barry, 2005: ocean surrounding the North Pole was ice-free, summer sea ice transitions through spring thaw, summer melt ponds, and autumn freeze-up, "Representation of Mean Arctic Precipitation from NCEP–NCAR and ERA Reanalyses", 10.1175/1520-0442(2000)013<0182:ROMAPF>2.0.CO;2, Aerosols May Drive a Significant Portion of Arctic Warming, "Studies of the Arctic Suggest a Dire Situation", Video on Climate Research in the Bering Sea, The Future of Arctic Climate and Global Impacts, How Climate Change Is Growing Forests in the Arctic, Arctic Ice Caps May Be More Prone to Melt; A new core pulled from Siberia reveals a 2.8-million-year history of warming and cooling, Chief Directorate of the Northern Sea Route, United Nations Convention on the Law of the Sea, Effects of global warming on marine mammals, https://en.wikipedia.org/w/index.php?title=Climate_of_the_Arctic&oldid=992016138, Articles with unsourced statements from July 2018, Wikipedia articles that may have off-topic sections from July 2018, All articles that may have off-topic sections, Creative Commons Attribution-ShareAlike License, The Arctic Basin includes the Arctic Ocean within the average minimum extent of sea ice, The entire island of Greenland, although its, The Arctic waters that are not sea ice in late summer, including. Precipitation over the north coast is similar to that over the central Arctic Basin. Many of these stations also collected meteorological data. The simulated weather data have a spatial resolution of approximately 30 km and may not reproduce all local weather effects, such as thunderstorms, local winds, or tornadoes. Third, because the Arctic temperature structure inhibits vertical air motions, the depth of the atmospheric layer that has to warm in order to cause warming of near-surface air is much shallower in the Arctic than in the tropics. Despite its location centered on the North Pole, and the long period of darkness this brings, this is not the coldest part of the Arctic. The lowest officially recorded temperature in the Northern Hemisphere is −67.7 °C (−89.9 °F) which occurred in Oymyakon on 6 February 1933, as well as in Verkhoyansk on 5 and 7 February 1892, respectively. The warm air transported into these regions also mean that liquid precipitation is more common than over the rest of the Arctic Basin in both winter and summer. By the early 19th century some expeditions were making a point of collecting more detailed meteorological, oceanographic, and geomagnetic observations, but they remained sporadic. Average temperatures in summer are above freezing over all regions except the central Arctic Basin, where sea ice survives throu… Changes have already been noticed in the High Arctic, including reduced sea ice. In addition to warm… Around the edges of the Arctic Ocean the ice will melt and break up, exposing the ocean water, which absorbs almost all of the solar radiation that reaches it, storing the energy in the water column. Most Arctic seas are covered by ice for part of the year (see the map in the sea-ice section below); 'ice-free' here refers to those which are not covered year-round. The dry winters result from the low frequency of cyclones in the region during that time, and the region's distance from warm open water that could provide a source of moisture (Serreze and Barry 2005). The 24-hour days found near the poles in summer result in a large daily-average solar flux reaching the top of the atmosphere in these regions. The National Oceanic and Atmospheric Administration’s annual Arctic Report Card, released on Tuesday, Dec. 8, 2020, shows how warming temperatures in the Arctic are transforming the region's geography and ecosystems. In 2014 we started to calculate weather models with historical data from 1985 onwards and generated a continuous 30-year global history with hourly weather data. Sea ice is bright and reflects about 80% of the sunlight that falls on it, helping to keep the surface cold. The extensive array of satellite-based remote-sensing instruments now in orbit has helped to replace some of the observations that were lost after the Cold War, and has provided coverage that was impossible without them. Variations in the amount of solar radiation reaching different parts of the Earth are a principal driver of global and regional climate. The Arctic is experiencing climate warmingfaster and more intensely than lower-latitude parts of the world. These forays into the Arctic did not venture far from the North American and Eurasian coasts, and were unsuccessful at finding a navigable route through either passage. Corrections are made to data to account for this uncaught precipitation, but they are not perfect and introduce some error into the climatologies (Serreze and Barry 2005). Since 2007, meteoblue has been archiving weather model data. The data is derived from our global NEMS weather model at approximately 30km resolution and cannot reproduce detail local weather effects, such as heat islands, cold air flows, thunderstorms or tornadoes. Arctic sea ice naturally shrinks and grows with the seasons, but scientists say global warming is accelerating melting to the point where summers in the Arctic … In the station-climatology figure above, the plot for Resolute is typical of this region. November 2020 ranked second hottest on record, overtaking November 2019 for the No. [13], A study published in the journal Science in September 2009 determined that temperatures in the Arctic are higher presently than they have been at any time in the previous 2,000 years. The small daily temperature range (the length of the vertical bars) results from the fact that the sun's elevation above the horizon does not change much or at all in this region during one day. The coastal regions in the southern part of the island are influenced more by open ocean water and by frequent passage of cyclones, both of which help to keep the temperature there from being as low as in the north. Sea ice is frozen sea water that floats on the ocean's surface. Likewise, "mean daily minimum" (solid blue line) shows the average minimum temperature. The largest temperature increases are in the Arctic and the Antarctic Peninsula. This map shows the location of Arctic research facilities during the mid-1970s and the tracks of drifting stations between 1958 and 1975. Cape Horn, the southernmost land point of South America, has a characteristic strong west-wind, which makes crossings from East to West very difficult especially for sailing boats. The presence of the islands, most of which lose their snow cover in summer, allows the summer temperatures to rise well above freezing. Air temperatures, at the standard measuring height of about 2 meters above the surface, can rise a few degrees above freezing between late May and September, though they tend to be within a degree of freezing, with very little variability during the height of the melt season. The precipitation chart is useful to plan for seasonal effects such as monsoon climate in India or wet season in Africa. The presence of the land allows temperatures to reach slightly more extreme values than the seas themselves. A cloudy sky can emit much more energy toward the surface than a clear sky, so when it is cloudy in winter, this region tends to be warm, and when it is clear, this region cools quickly.[2]. Weather models comparison for Arctic Archipelago. Water in lakes and streams fed by glacial meltwater is cloudy, due to the large amounts of sediment – sand, silt, and clay – that is released with the meltwater.
