Precipitation in most of the Arctic falls only as rain and snow. Some locations near these coasts where the terrain is particularly conducive to causing orographic lift receive up 2,200 mm (87 in) of precipitation per year. Low spring and summer cloud frequency and the high elevation, which reduces the amount of solar radiation absorbed or scattered by the atmosphere, combine to give this region the most incoming solar radiation at the surface out of anywhere in the Arctic. 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. ), we offer high resolution simulations with hourly data. 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]. The Soviet Union was also interested in the Arctic and established a significant presence there by continuing the North-Pole drifting stations. The meteoblue climate diagrams are based on 30 years of hourly weather model simulations and available for every place on Earth. 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. Variations in cloud cover can cause significant variations in the amount of solar radiation reaching the surface at locations with the same latitude. Beginning in 1979 the Arctic Ocean Buoy Program (the International Arctic Buoy Program since 1991) has been collecting meteorological and ice-drift data across the Arctic Ocean with a network of 20 to 30 buoys. Over most areas snow is the dominant, or only, form of precipitation in winter, while both rain and snow fall in summer (Serreze and Barry 2005). [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. These pieces of software are sometimes relatively simple, but often become highly complex as scientists try to include more and more elements of the environment to make the results more realistic. As the snow disappears on land, the underlying surfaces absorb even more energy, and begin to warm rapidly. 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]. This map shows the location of Arctic research facilities during the mid-1970s and the tracks of drifting stations between 1958 and 1975. An essentially ice-free Arctic may be a reality in the month of September, anywhere from 2050 to 2100.[4]. As a result, the most complete collection of surface observations from the Arctic is for the period 1960 to 1990.[2]. During the winter months of November through February, the sun remains very low in the sky in the Arctic or does not rise at all. Download variables like temperature, wind, clouds and precipitation as CSV for any place on Earth. For vacation planning, you can expect the mean temperatures, and be prepared for hotter and colder days. Cold snow reflects between 70% and 90% of the solar radiation that reaches it,[2] and snow covers most of the Arctic land and ice surface in winter. [16] Geologists were able to track the summer Arctic temperatures as far back as the time of the Romans by studying natural signals in the landscape. The temperature is a November record for the entire archipelago that sits well above the Arctic Circle. The global average temperature is warming but the air temperatures in the Arctic are increasing twice as fast or possibly faster.The year 2019 will go down as the second-lowest minimum extent of sea ice. While the station was installed just last October, Svalbard weather data extends back to the start of the 20th century. The largest temperature increases are in the Arctic and the Antarctic Peninsula. In most of the Arctic the significant snow melt begins in late May or sometime in June. On average, these motions carry sea ice from the Russian side of the Arctic Ocean into the Atlantic Ocean through the area east of Greenland, while they cause the ice on the North American side to rotate clockwise, sometimes for many years. This program operated continuously, with 30 stations in the Arctic from 1950 to 1991. The maps on the right show the average temperature over the Arctic in January and July, generally the coldest and warmest months. An interesting example is the Tibetan Plateau, where the monsoon creates steady strong winds from December to April, and calm winds from June to October. By November, winter is in full swing in most of the Arctic, and the small amount of solar radiation still reaching the region does not play a significant role in its climate. During these early months of Northern Hemisphere spring most of the Arctic is still experiencing winter conditions, but with the addition of sunlight. This one was larger than the first, with 94 meteorological stations, but World War II delayed or prevented the publication of much of the data collected during it. 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. By July and August, most of the land is bare and absorbs more than 80% of the sun's energy that reaches the surface. 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 … More precipitation falls in winter, when the storm track is most active, than in summer. Please let us know if you agree. Weather Forecast Canadian Arctic Archipelago - Canada (Nunavut) ☼ Longitude : -93.5 Latitude : 74 Altitude : 83m ☀ Le Canada est le 2ème plus grand pays du monde avec une superficie de presque 10 millions de km carrés. Sea ice is frozen sea water that floats on the ocean's surface. Much of the ice sheet remains below freezing all year, and it has the coldest climate of any part of the Arctic. This is especially true near the coast, where the terrain rises from sea level to over 2,500 m (8,200 ft), enhancing precipitation due to orographic lift. 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. Svalbard weather. 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. 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). [2] As a result, expeditions from the second half of the nineteenth century began to provide a picture of the Arctic climate. 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. Svalbard is a Norwegian archipelago in the Arctic Ocean. 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). It shows the average temperature in the coldest months is in the −30s, and the temperature rises rapidly from April to May; July is the warmest month, and the narrowing of the maximum and minimum temperature lines shows the temperature does not vary far from freezing in the middle of summer; from August through December the temperature drops steadily. Usually, February is a freezing month at the far Arctic archipelago of Svalbard. 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. Climate is defined by the World Meteorological Organization as the average weather over a 30-year period. 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. This expedition also provided valuable insight into the circulation of the ice surface of the Arctic Ocean. The Greenland Ice Sheet covers about 80% of Greenland, extending to the coast in places, and has an average elevation of 2,100 m (6,900 ft) and a maximum elevation of 3,200 m (10,500 ft). [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. 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]. Dubai, one of the hottest cities on earth, has almost none days below 40°C in July. The continued low temperatures, and the persisting white snow cover, mean that this additional energy reaching the Arctic from the sun is slow to have a significant impact because it is mostly reflected away without warming the surface. Likewise, in the beginning of September both the northern and southern land areas receive their winter snow cover, which combined with the reduced solar radiation at the surface, ensures an end to the warm days those areas may experience in summer. 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. 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. As a result, precipitation amounts over these parts of the basin are larger in winter than those given above. Photographer Elena Chernyshova explores what it’s like to live in a city 400km north of the Arctic Circle. Particularly the eastern part of Svalbard sees relatively little precipitation annually. The first diagram shows the predicted temperatures for each model. Wind speeds are not displayed per default, but can be enabled at the bottom of the graph. 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. As the amount of solar radiation available to the surface rapidly decreases, the temperatures follow suit. Modern researchers in the Arctic also benefit from computer models. These regions receive many weakening cyclones from the North-Atlantic storm track, which is most active in winter. Accurate climatologies of precipitation amount are more difficult to compile for the Arctic than climatologies of other variables such as temperature and pressure. In 1966 the first deep ice core in Greenland was drilled at Camp Century, providing a glimpse of climate through the last ice age. These regions have summer temperatures between about 0 and 8 °C (32 and 46 °F). 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. 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. [2]. The maximum temperature diagram for Arctic Archipelago displays how many days per month reach certain temperatures. Annual precipitation totals increase quickly from about 400 mm (16 in) in the northern to about 1,400 mm (55 in) in the southern part of the region. Furthermore, most of the small amount of solar radiation that reaches the surface is reflected away by the bright snow cover.
