Zomera zochepa, matalala ndi chipale chofewa ndizofunikira kwambiri m'chipululu cha Arctic. Madera osazolowereka amapita kudera lakumpoto kwa Asia ndi North America. Madera achisanu amapezekanso kuzilumba za Arctic Basin, zomwe zimapezeka mdera la polar. Dera la chipululu cha Arctic limakhala lokutidwa ndi zidutswa zamiyala.
Kufotokozera
Chipululu chokhala ndi chipale chofewa chimapezeka kumtunda kwenikweni kwa Arctic. Chimakwirira dera lalikulu ndipo chimafikira pa chipale chofeŵa ndi chipale chofeŵa makilomita zikwizikwi. Nyengo yosavomerezeka yakhala chifukwa cha zomera zopanda pake, chifukwa chake, palinso oimira ochepa nyama. Ndi nyama zochepa zokha zomwe zimatha kusintha kutentha, komwe kumafika -60 madigiri m'nyengo yozizira. M'chilimwe, zinthu zimakhala bwino kwambiri, koma madigiriwo sakwera pamwamba +3. Mpweya wam'mlengalenga m'chipululu cha arctic sukupitilira 400 mm. M'nyengo yotentha, chipale chofewa chimasungunuka, ndipo dothi limanyowetsedwa ndi matalala.
Nyengo yovutayi imapangitsa kuti mitundu yambiri ya nyama isakhale m'malo amenewa. Chivundikirocho, chopangidwa ndi chisanu ndi ayezi, chimakhala miyezi khumi ndi iwiri yonse. Usiku wa kum'mwera kumawerengedwa kuti ndi nthawi yovuta kwambiri m'chipululu. Itha kukhala pafupifupi miyezi isanu ndi umodzi. Pakadali pano, kutentha kumachepa mpaka pafupifupi madigiri -40, komanso mphepo zamkuntho zamkuntho, mkuntho wamphamvu. Ngakhale kuyatsa nthawi yotentha, nthaka singasungunuke chifukwa pamakhala kutentha pang'ono. Nthawi imeneyi ya chaka imadziwika ndi mitambo, mvula ndi chipale chofewa, nkhungu zazikulu komanso kuwerengera kutentha mkati mwa madigiri 0.
Zinyama zam'chipululu
Dera la chipululu cha Arctic ku North America ndi komwe kuli nyama zochepa. Izi ndichifukwa cha kusowa kwaudzu, komwe kumatha kukhala chakudya cha nyama. Mwa oyimira odziwika bwino padziko lonse lapansi ndizisindikizo, mimbulu yanyanja, mandimu, ma walrus, zisindikizo, zimbalangondo zakumtunda ndi mphalapala.

Kadzidzi ku Arctic, ng'ombe za musk, guillemots, nkhandwe, ma gulls, ma eider ndi puffins amasinthidwanso kukhala nyengo yovuta. Kwa gulu la cetaceans (narwhals, bowhead whales, polar dolphins / beluga whale), zipululu za arctic ndizovomerezeka pamoyo.

Mwa nyama zochepa zomwe zimapezeka kuzipululu zakumpoto kwa North America, mbalame zimawonedwa kuti ndizofala kwambiri. Woyimira chidwi ndi duwa lakuda, lomwe limakula mpaka masentimita 35. Kulemera kwake kwa mbalame kumafikira 250 g, zimapirira nyengo yozizira yozizira ndikukhala pamwamba panyanja yokutidwa ndi madzi oundana otengeka.

Ma guillemots amakonda kukhala pamapiri ataliatali ndipo samamva kukhala pakati pa ayezi.
Abakha akumpoto (eider) amalumphira m'madzi oundana mpaka mamita 20. Kadzidzi amadziwika kuti ndi mbalame yayikulu kwambiri komanso yoopsa kwambiri. Ndi nyama yolusa yomwe imaphedwa mwankhanza ndi makoswe, nyama zazing'ono ndi mbalame zina.
Zomera za m'chipululu cha ayezi
Omwe akuyimira kwambiri zomera za m'chipululu cha glacial ndi mosses, lichen, herbaceous plants (dzinthu, kubzala nthula). Nthawi zina m'malo ovuta mumatha kupeza Alpine foxtail, arctic pike, buttercup, chipale chofewa saxifrage, poppy polar ndi bowa wosiyanasiyana, zipatso (cranberries, lingonberries, cloudberries).

Zonsezi, zomera za m'zipululu za Arctic ku North America sizoposa mitundu ya zomera 350. Mavutowa amalepheretsa nthaka kupanga nthaka, chifukwa ngakhale chilimwe dziko lapansi silikhala ndi nthawi yosungunuka. Komanso, ndere zimasiyanitsidwa pagulu limodzi, momwe pali mitundu pafupifupi 150.
