| 词条 | Ritsem |
| 释义 |
Ritsem, among other things has a hydroelectric plant(320MW,160m) which is located where the lake Sitasjaure falls into Akkajaure by a constructed tunnel(16km made by:"Swedish state powerboard"Vattenfall""). The location also has a camp used by the Sami people, and there is even a mountain cabin and Caravan camp run by the Svenska Turistföreningen.[1] The cabin is mostly used by tourists who are traveling to/from Northern Padjelanta and Northern Sarek and are using the ferry (run by Svenska Turistföreningen) across Akkajaure. Ritsem is located near the Stora Sjöfallet National Park. There is a regular bus line between Ritsem and Gällivare during both summer and winter. ClimateRitsem has a subarctic climate that is significantly moderated by the North Atlantic Current outside of the nearby Norwegian coastline. As a result, summers are chilly and winters cold, but not severely cold when compared to areas on such northerly latitudes elsewhere in the world. Given its very high latitude, Ritsem sees a long midnight sun period in summer, whereas a shorter polar night period with significant twilight hours occurs in winter. Due to the low sun however, summers can see frost well inside the midnight sun period. Ritsem's all-time record is lower than any other of the 100 stations featured in the national weather service's monthly reports.[2] It does have to be taken into account that these records only date back to 1981. By the time Atlantic depressions set in during late autumn, temperatures are far milder in Ritsem than further east and even further south in the country. Days above freezing are common throughout November. The ensuing winters very seldom see temperatures fall below {{convert|-30|C|F}}, unlike in the aforementioned areas. Even though the marine air is strong during winter, precipitation in form of snow is normally not extreme. {{Weather box|location = Ritsem (temperature 2002-2015; precipitation 1961-1990; extremes since 1981) |metric first = Yes |single line = Yes |Jan record high C = 5.8 |Feb record high C = 5.5 |Mar record high C = 7.6 |Apr record high C = 12.4 |May record high C = 24.6 |Jun record high C = 26.6 |Jul record high C = 27.1 |Aug record high C = 26.0 |Sep record high C = 19.2 |Oct record high C = 14.7 |Nov record high C = 9.7 |Dec record high C = 6.2 |year record high C = 27.1 |Jan high C = -6.3 |Feb high C = -5.4 |Mar high C = -3.3 |Apr high C = 1.8 |May high C = 7.0 |Jun high C = 12.4 |Jul high C = 16.8 |Aug high C = 15.1 |Sep high C = 9.3 |Oct high C = 3.2 |Nov high C = -0.8 |Dec high C = -3.7 |year high C = 3.8 |Jan mean C = -10.0 |Feb mean C = -9.0 |Mar mean C = -7.0 |Apr mean C = -1.5 |May mean C = 3.7 |Jun mean C = 8.7 |Jul mean C = 12.5 |Aug mean C = 11.5 |Sep mean C = 6.5 |Oct mean C = 0.7 |Nov mean C = -3.7 |Dec mean C = -7.0 |year mean C = 0.4 |Jan low C = -13.7 |Feb low C = -12.7 |Mar low C = -10.7 |Apr low C = -4.9 |May low C = 0.5 |Jun low C = 5.0 |Jul low C = 8.4 |Aug low C = 7.9 |Sep low C = 3.6 |Oct low C = -1.7 |Nov low C = -6.5 |Dec low C = -10.3 |year low C = -2.9 |Jan record low C = -31.5 |Feb record low C = -32.0 |Mar record low C = -30.8 |Apr record low C = -22.3 |May record low C = -13.0 |Jun record low C = -4.5 |Jul record low C = 0.8 |Aug record low C = -0.6 |Sep record low C = -9.5 |Oct record low C = -15.2 |Nov record low C = -27.0 |Dec record low C = -29.0 |year record low C = -32.0 |Jan precipitation mm = 46.4 |Feb precipitation mm = 35.5 |Mar precipitation mm = 25.6 |Apr precipitation mm = 25.5 |May precipitation mm = 26.6 |Jun precipitation mm = 30.9 |Jul precipitation mm = 64.8 |Aug precipitation mm = 60.3 |Sep precipitation mm = 47.0 |Oct precipitation mm = 47.6 |Nov precipitation mm = 43.9 |Dec precipitation mm = 56.1 |year precipitation mm = 510.1 |source 1 = SMHI precipitation average 1961-1990[3] |source 2 = SMHI climate data 2002-2015[4]}} References1. ^http://www.svenskaturistforeningen.se/sv/upptack/Omraden/Lappland/Fjallstugor/STF-Fjallstuga-ritsem/ 2. ^{{cite web|url=http://data.smhi.se/met/climate/time_series/month/vov_pdf/SMHI_vov_temperature_wind_jul15.pdf?66125|title=July 2015 Temperature & Winds - all time records section|publisher=SMHI|accessdate=22 June 2016}} 3. ^{{cite web| url =http://data.smhi.se/met/climate/time_series/month_year/normal_1961_1990/SMHI_month_year_normal_61_90_precipitation_mm.txt|title=Precipitation normals 1961-1990 (Swedish)| publisher =Swedish Meteorological and Hydrological Institute (Ritsem code 17 792 ) | language = }} 4. ^{{cite web| url=http://www.smhi.se/klimatdata/meteorologi/temperatur/2.1240| title=Yearly & Monthly statistics (Swedish)| publisher = SMHI| date= June 22, 2016}} External links
