what is the weather like in arctic archipelago

NOAA's annual Arctic Report Card, released on Tuesday, Dec. 8, … 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. Marlink is providing vital connectivity for an Arctic Climate Science project – Hearts in the Ice.. Neither the models nor the data are perfect, so these maps may differ from other estimates of surface temperatures; in particular, most Arctic climatologies show temperatures over the central Arctic Ocean in July averaging just below freezing, a few degrees lower than these maps show [2][3](USSR, 1985)[citation needed]. weather anomaly Arctic Archipelago Sees October Temps 10 Degrees Hotter Than Normal The Russian archipelago of Severnaya Zemlya also saw the … Much of the winter variability in this region is due to clouds. This period of setting sun also roughly corresponds to summer in the Arctic. They are also used to try to predict future climate and the effect that changes to the atmosphere caused by humans may have on the Arctic and beyond. The project is led by Hilde Fålun Strøm and Sunniva Sorby, two experienced Arctic explorers who will be spending seven months in a trapper’s hut in Bamsebu, in the Norwegian Arctic Archipelago of Svalbard. These frequent cyclones lead to larger annual precipitation totals than over most of the Arctic. The presence of the land allows temperatures to reach slightly more extreme values than the seas themselves. During these ice ages, large areas of northern North America and Eurasia were covered by ice sheets similar to the one found today on Greenland; Arctic climate conditions would have extended much further south, and conditions in the present-day Arctic region were likely colder. By May, temperatures are rising, as 24-hour daylight reaches many areas, but most of the Arctic is still snow-covered, so the Arctic surface reflects more than 70% of the sun's energy that reaches it over all areas but the Norwegian Sea and southern Bering Sea, where the ocean is ice free, and some of the land areas adjacent to these seas, where the moderating influence of the open water helps melt the snow early.[2]. For comparison, annual precipitation averaged over the whole planet is about 1,000 mm (39 in); see Precipitation). Where sea ice remains, in the central Arctic Basin and the straits between the islands in the Canadian Archipelago, the many melt ponds and lack of snow cause about half of the sun's energy to be absorbed,[2] but this mostly goes toward melting ice since the ice surface cannot warm above freezing. Unless otherwise noted, all precipitation amounts given in this article are liquid-equivalent amounts, meaning that frozen precipitation is melted before it is measured. As the snow disappears on land, the underlying surfaces absorb even more energy, and begin to warm rapidly. [15] Samples from ice cores, tree rings and lake sediments from 23 sites were used by the team, led by Darrell Kaufman of Northern Arizona University, to provide snapshots of the changing climate. [9], During all seasons, the strongest average winds are found in the North-Atlantic seas, Baffin Bay, and Bering and Chukchi Seas, where cyclone activity is most common. 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. Svalbard weather. Fifty years after the first IPY, in 1932 to 1933, a second IPY was organized. 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. The interior ice sheet remains snow-covered throughout the summer, though significant portions do experience some snow melt. The climate of the Arctic also depends on the amount of sunlight reaching the surface, and being absorbed by the surface. In addition the length of each day, which is determined by the season, has a significant impact on the climate. 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 / … 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. Though the Vikings explored parts of the Arctic over a millennium ago, and small numbers of people have been living along the Arctic coast for much longer, scientific knowledge about the region was slow to develop; the large islands of Severnaya Zemlya, just north of the Taymyr Peninsula on the Russian mainland, were not discovered until 1913, and not mapped until the early 1930s 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. FILE – In this July 24, 2017 file photo, an iceberg floats past Bylot Island in the Canadian Arctic Archipelago. The precipitation diagram for Arctic Archipelago shows on how many days per month, certain precipitation amounts are reached. [2] The Arctic is experiencing climate warmingfaster and more intensely than lower-latitude parts of the world. But what makes Canada’s Arctic so different from many of the other Arctic regions in the world are its islands. These reanalysis datasets help compensate for the lack of observations over the Arctic. 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. This region is continuously below freezing, so all precipitation falls as snow, with more in summer than in the winter time. Sea ice is frozen sea water that floats on the ocean's surface. [2] Another significant moment in Arctic observing before World War II occurred in 1937 when the USSR established the first of over 30 North-Pole drifting stations. 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. 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. (USSR 1985). 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]. While Reykjavík on Iceland has mostly cloudy days, Sossusvlei in the Namib desert is one of the sunniest places on earth. Between 1947 and 1957, the United States and Canadian governments established a chain of stations along the Arctic coast known as the Distant Early Warning Line (DEWLINE) to provide warning of a Soviet nuclear attack. This map shows the location of Arctic research facilities during the mid-1970s and the tracks of drifting stations between 1958 and 1975. These have very small annual temperature variations; average winter temperatures are kept near or above the freezing point of sea water (about −2 °C (28 °F)) since the unfrozen ocean cannot have a temperature below that, and summer temperatures in the parts of these regions that are considered part of the Arctic average less than 10 °C (50 °F). [7], The map at right shows the areas covered by sea ice when it is at its maximum extent (March) and its minimum extent (September). The North Atlantic Current moderates Svalbard's temperatures, particularly during winter, giving it up to 20 °C higher winter temperature than … 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). Much of the ice sheet remains below freezing all year, and it has the coldest climate of any part of the Arctic. In the figure above showing station climatologies, the lower-left plot, for NP 7–8, is representative of conditions over the Arctic Basin. In summer, the coastal regions of Greenland experience temperatures similar to the islands in the Canadian Archipelago, averaging just a few degrees above freezing in July, with slightly higher temperatures in the south and west than in the north and east. Photographer Elena Chernyshova explores what it’s like to live in a city 400km north of the Arctic Circle. Beginning in the 1850s regular meteorological observations became more common in many countries, and the British navy implemented a system of detailed observation. 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. Normally, the average February temperature at Svalbard is minus 16,2 degrees. 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. In the station climatology figure above, the Centrale plot is representative of the high Greenland Ice Sheet. Auyuittuq National Park is home to iconic mountains Sea ice is important to the climate and the ocean in a variety of ways. Second, because colder air holds less water vapour than warmer air, in the Arctic, a greater fraction of any increase in radiation absorbed by the surface goes directly into warming the atmosphere, whereas in the tropics, a greater fraction goes into evaporation. 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. Changes in the Arctic have global implications. The northern islands receive similar amounts, with a similar annual cycle, to the central Arctic Basin. Eleven nations provided support to establish twelve observing stations around the Arctic. Sixteenth- and seventeenth-century expeditions were largely driven by traders in search of these shortcuts between the Atlantic and the Pacific. The average high temperature in summer approaches 10 °C (50 °F), and the average low temperature in July is above freezing, though temperatures below freezing are observed every month of the year. The east coast of the central third of the island receives between 200 and 600 mm (7.9 and 23.6 in) of precipitation per year, with increasing amounts from north to south. The ice may be bare ice, or it may be covered by snow or ponds of melt water, depending on location and time of year. 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. In September and October the days get rapidly shorter, and in northern areas the sun disappears from the sky entirely. Modern researchers in the Arctic also benefit from computer models.
