Kwete mukupfuura kweArctic Circle mudziyo nemvura inotonhora uye chando anogeza nemahombekombe makondinendi, hemispheres uye Groenlândia kubva kuchamhembe. Avhareji udzamu kweArctic Ocean iri zvakanaka diki, asi mvura mairi coldest. Pamusoro nzvimbo - mamiriyoni 14,75 mativi makiromita, vhoriyamu - 18.070.000 cubic makiromita. Avhareji udzamu kweArctic Ocean muna metres - 1225, apo gobvu pfungwa iri pana 5527 metres pazasi pemvura. Pfungwa iyi ndohwaJehovha bheseni kweGungwa Zimbabwe.

pasi gandiwa

About kuti, chii paavhareji uye kufadza kudzika kweArctic Ocean, masayendisiti akadzidza kare, asi izvi pamusoro pasi ruyamuro kukwira kuhondo 1939-1945 anenge chinhu chakazozikamwa. Mumakore gumi apfuura, mumwe mujenya siyana mashoko ikaunganidzwa kuburikidza nzendo pamusoro dzinopwanya aizi uye Ngarava dzepasi pemvura. In sechivako pasi nechepakati mukaha uri kure, izvo dziri kumativi shoma gungwa.

Chinenge hafu yacho yaigara penyanza pasherufu. The Russian ndima, akatambanudza kusvika 1300? Km kupfuura pasi. Pedyo European pamhenderekedzo pasherefu iri zvikuru kudzika uye gogonera chaizvo. Kune mazano kuti kwakaitika pasi pokudzora Pleistocene mazitombo echando. Muzinda chinhu negomba denderedzwa mukuru udzamu, iyo inokamukana muhomba University, yakawanikwa uye vakadzidza omei pashure pehondo. Eurasian pakati pasherefu akati muhomba atambanudza bheseni ane udzamu ari pakati 4 uye 6 km. Kune rimwe divi muhomba atambanudza muchanza wechipiri, izvo 3400m udzamu.

From Pacific Arctic hwakabatana Bering Strait, akasungwa pamwe Atlantic anomhanya kuburikidza Sea Norwegian. Sechivako pasi muitire rakakura pave pemvura uye pasi pemvura Continental nzvimbo. Izvi anotsanangura yakaderera chaizvo avhareji kudzika kweArctic Ocean - anopfuura 40% of nzvimbo haina kudzika kudarika 200 M vamwe iri kumhenderekedzo ..

dzinongoitika ezvinhu

Ocean Climate vagara vandifungira nzvimbo yaro. utsinye okunze ari kuwedzera nokuti vabereki guru yakawanda chando - gobvu rukoko asingagari zvinonyauka nokusingaperi nechepakati chikamu bheseni.

Yegore iri kweArctic madutu kukudziridza. Anticiklon kushingaira runonyanya muchando, apo muzhizha zviri ndanogara mhesano pamwe nePacific Ocean. Madutu noumharadzi pamusoro munharaunda yezhizha. Nokuda neshanduko iyi polar chando yakajeka Misiyano mumhepo kumanikidzwa. Winter kunotora November kusvika April, zhizha - kubva June kusvika August. Kunze kwakatanga pamusoro penyanza madutu pano kazhinji vanofamba madutu kuti vaibva kunze.

Mhepo hurumende iri North Pole haisi yunifomu, asi nokukurumidza rinopfuura 15 m / S kushanda zvikasaitika. Mhepo pamusoro kweArctic Ocean advantageously vane nokumhanya 3-7 m / s.
Paavhareji tembiricha iri chando - +4 kusvika -40 zhizha - kubva 0 kusvika +10 Celsius.

Low makore ane mumwe periodicity mukufamba kwegore. Muchirimo, mukana wokuti yakaderera makore rinosvika 90-95% munguva yechando - 40-50%. denga Clear zvinowanzoitika kuti chando mwaka. Summer fogs vari kakawanda, dzimwe nguva havaiti kusimuka kuti vhiki.

Kunonaya, hwakanga nzvimbo iyi - chando. Mvura inenge regai kuitika, uye kana vari, ari kakawanda nesinou. Falls pagore 80-250 neMM, mudunhu Europe kuchamhembe kweArctic Basin - zvishoma. The chando chakanyanya kuderera, hazvina zvakaenzana anoparadzirwa. Munyaya anodziya mwedzi, chando inonyunguduka vachishingaira, dzimwe nguva anoenda kure zvachose.

The dzinotaurwa nechepakati nharaunda iri manyoro kupfuura noruwa (pedyo nemahombekombe Asian chikamu Eurasia uye North America). Mvura zvinopfuura inodziya dzenzvimbo Atlantic, izvo zvinoumba chadenga yose mvura nzvimbo munyanza.

Biota

Avhareji udzamu kweArctic Ocean ndiye zvakakwanira kwaita vazhinji siyana zvinenge zviri chomupepanhau yake. Munharaunda yeAtlantic kazhinji dzinogona kuonekwa nhamba akasiyana-siyana hove dzakadai cod, gungwa Bass, herring, haddock, saithe. Mugungwa inogarwa hove huru, kunyanya Greenlandic uye mitsetse.

In zvikuru kweArctic hapana miti, kunyange kuchamhembe Russia uye Air Peninsula ichikura spruce, nemipaini uye kunyange Birch. Zvinomera achinaya mvura raimiririra bota, lichens, vanoverengeka mhando Birch, petsanga, zvipfupi nemikonachando. Summer ipfupi, asi chando iri nemafashamo pamwe zuva nemwaranzi, kunomutsa basa kukura nemiti. Ivhu inogona kudziyirwa chokumusoro akaturikidzana 20 madhigirii, uye kuwedzera neyamapani tembiricha mhepo akaturikidzana.

The peculiarity pamusoro fauna of kweArctic - kuitwa kwemarudzi zvakawanda vamiririri neimwe. The Arctic - musha kune polar mabheya, arctic makava, chena-namazizi, shiri, rarira, partridges uye achinaya mvura lemmings. Mumakungwa vachisasa walrus nemombe, narwhals, zvisimbiso beluga hove huru.

Kwete chete avhareji uye kufadza kudzika kweArctic Ocean kuwanda mhuka uye zvinomera vakananga pakati penyanza zvinoderedza yacho arambe achirema zhinji mhuka kuti agare nzvimbo yacho.
