Lamadegaanka Arctic

Far North Asia iyo North America mashquulin cidlada cidhifka woqooyi - meel aan Noolayn la Dhirta aad Finensej, oo ku yaalla ee barafka iyo barafka. Bbc Kuwani waa dabeecadda u ah inta badan dalka reer Greenland si Arctic Canadian ah Jasiiradaha iyo jasiiradaha kale ee Basin Arctic iyo jasiiradaha ku yaal xeebaha Jacaylku.

Cimilada ee aaga dabiiciga ah ee qabow ee cidhifka woqooyi. Qaboobuhu yihiin dheer iyo aad u daran (heerkulka celcelis ahaan - -10 si -35 ° C) iyo xagaayada gaaban oo qabow (0 ... + 5 ° C). Winter boqor habeen kala horjeeda, kuwaas oo, ku xiran tahay loolka ah, fidiyaa ka 98 maalmood ilaa lix bilood. Bishii June, waqti isku mid ah ula Bilowgii hore ee maalinta kala horjeeda, oo lamadegaanka cidhifka woqooyi si tartiib ah u timid inaad nolosha - guga yimaado. In kasta oo xaqiiqda ah in qorraxda wuxuu u iftiimaa saacad, carradu dhalaaliso oo kaliya dhowr sentimitir. Inta lagu jiro muddada gaaban inta lagu guda jiro kuwaas oo heerkulka waa positive, tag barafka oo kaliya in qaybo yaryar oo leh carradu kaneecada iyo dhagax ah.

Xilliga xagaaga, cirku waa dhif cad; sida caadiga ah waxaa baynamutaan siiyo roobab dheer (roobka, barafka inta badan). Muddadan, dhulka inta badan dabooli ceeryaanta qaro weyn ee ay uumi oo biyo ah ka dusha badda. Dhammaan qoyaanka Hawada weli dushiisa, ma uumi sababta oo ah booska ugu hooseeya ee Qorraxda iyo kul hoose, iyo Jeenawari ma dhulka qaboojiyey.

Waayo, zone this dabiiciga ah waxa lagu gartaa Muuse crustose, lichens iyo cows ku habboon nolosha ee waqooyiga. Meelaha daboolay Dhirta - nooc ka mid ah abaabulan dhexe ee barafka kala horjeeda iyo barafka, dhiirogelin cidlada cidhifka woqooyi. Halkan waxaad kula kulmi kartaa wakiilada ee dhirta ubax: saxifrage, foxtail iyo qaar ka mid ah dalagga kale, buttercup, calaamada cidhifka woqooyi, cranberries, dareemaduna. No ku xoortay geedihii iyo lichens, Muuse iyo noocyada herbaceous ma sameeyaan cover a joogto ah. height Plant dhif ka badan 10 cm, maxaa yeelay, hawada qabow la kululeeyo ka dalka cidhifka woqooyi iyo xagga hoose yara diirran. Cararaya dhirta dabaysha lagu cadaadiyey soo horjeeda dhagaxyada iyo degeen Niyadjabka, in marnay oo ka mid ah qarar oo sarreeya kale dhul, on dalcadaha koonfurta-gaadhista.

dubato jidhadhka dhulka ee aagga this dabiiciga ah waa mid aad u liita. Waxay hoy u tahay oo dawaco, lemmings, oo orso oo kala horjeeda. Xilliga xagaaga waxaa jira "rookeries": kaalay oo xilliga kulaylaha eider, guillemot, sandpiper, kittiwake, fulmar, guillemot, goose iyo noocyada kale. More hodan ku dubato badda.

zone cidlada Arctic of Russia ee koonfurta gaadho loolka ee Wrangel Island iyo tan iyo woqooyi waa xadidan oo ay ku gasiiradaha Franz Josef Land.

Badanaa glaciers qaarada dhexdeeda Godoo kale ilaa badda, baddayna ku jebi, la xirrira icebergs. On dalka, baraf-free, jirkiisa kala baahsan.

Jirkiisa, xagaaga qabow iyo gaaban iyo Dhirta Finensej abuuro xaaladaha allifey oo loogu talagalay nidaamka ciidda-sameynta. Sidaa darteed, ciidda dhulka ee aagga dabiiciga ah low-xoog, dhagaxa, masaakiinta.

Si kastaba ha ahaatee, inkastoo ay yaraadan ee xad-dhaaf ah ee ciidda iyo daaqsinka, iyo cidlada cidhifka woqooyi Russia waxaa lagu gartaa isbeddel ku Halabuurka noocyada jihada latitudes. Si zone woqooyi waxa lagu gartaa bulshooyinka cawska-ajada in u badalo dhammaaday koonfureed ee geed-ajada. In koonfureed ee ugu shishaysa ee lamadegaanka cidhifka woqooyi nooca geed-ajada caadiga ah la mid ah, laakiin la cover a loogu dhawaaqaa baadiyaha.
