ʻO ke ʻano o ke aniau ʻano maʻamau no ka teritori o nā kāʻei arctic a me nā kāʻei subarctic. Aia kekahi hanana e like me ka pō polar, ke ʻikea ʻole ka lā ma luna o ka pae no kahi manawa lōʻihi. I kēia wā, ʻaʻole lawa ka wela a me ke kukui.
Nā hiʻohiʻona o ke aniau Arctic
ʻO ke ʻano o ke aniau arctic kahi ʻano paʻakikī loa. Maʻaneʻi wale nō i kekahi mau manawa o ka makahiki e piʻi ai ka mahana ma luna o ka ʻole, i ke koena o ka makahiki - nā hau. Ma muli o kēia, ua hoʻokumu ʻia nā glacier ma aneʻi, a he ʻāpana hau ka uhi o ka ʻāpana o ka ʻāina nui. ʻO ia ke kumu i hoʻokumu ʻia ai kahi honua kūikawā flora a me nā holoholona ma aneʻi.
Hoakaka
Nā ʻano nui o ke aniau Arctic:
- hoʻoilo loa;
- kauwela pōkole a me ke anuanu;
- makani ikaika;
- he ua liʻiliʻi.
ʻIppilipili
Hoʻokaʻawale ʻia ka ʻāpana aniau ʻo Arctic i ʻelua mau ʻano. Ma kahi o ka ʻāinapuniʻole, ma kahi o 100 mau mile o ka ua e hāʻule i kēlā me kēia makahiki, i kekahi mau wahi - 200 mm. I ka ʻāpana o ke aniau kai, hāʻule ka ua ma lalo o ka liʻiliʻi. Hāʻule ka hapa nui o ka hau, a i ke kauwela wale nō, ke piʻi iki ka mahana i 0 kekelē Celsius, ua.
Teritori o ke aniau arctic
ʻO ke aniau Arctic kahi mea maʻamau no nā wahi polar. Ma ka Hemisphere Hema, ʻike nui ʻia kēia ʻano aniau ma nā ʻāina o ka ʻāina Antarctic. A ʻo ka ʻĀkau hoʻi, uhi ia i ka Moana Arctic, nā wahi o waho o ʻAkau ʻAmelika a me Eurasia. Eia ke kāʻei kūlohelohe o nā wao nahele arctic.
Nā holoholona
ʻOi aku ka maikaʻi ʻole o ka holoholona i loko o ka wahi kai o ka Arctic climatic, ʻoiai e hoʻololi nā mea ola i nā kūlana paʻakikī. ʻO nā ʻīlio hae ʻĀkau a me nā lemona, ʻo nā dia a me nā ʻalopeke poli ʻo Nūhōlani e noho ana ma nā panalāʻau o nā ʻāina a me nā mokupuni. Aia nā heluna o nā bipi musk ma Greenland. ʻO kekahi o nā kamaʻāina maʻamau o ke aniau Arctic ka bear polar. Noho ʻo ia ma ka ʻāina a ʻau i ka wai.
Hōʻike ʻia ka honua manu e nā pueo polar, nā guillemots, nā eider, nā ʻōkela rosy. Aia nā pūʻulu sila a me nā walrus ma ke kahakai. ʻO ka haumia o ka lewa, ka moana o ka Honua, ka hoʻoheheʻe ʻana o nā aniani, ka hoʻomehana honua ʻana i mea e hōʻemi ai ka heluna o nā holoholona a me nā manu. Pale ʻia kekahi ʻano e nā mokuʻāina like ʻole. No kēia, hana ʻia nā mālama ʻāina.
Mea kanu
ʻO ka flora o ka tundra a me ka wao akua i ke aniau arctic kahi maikaʻi ʻole. ʻAʻohe lāʻau ma aneʻi, he laʻalāʻau wale, mauʻu, moʻo a me nā limu. I kekahi mau wahi, i ke kauwela, ulu nā pīpī polar, polū polū, alopeke alpine, sedge, a me nā cereal. ʻO ka hapa nui o nā mea kanu ma lalo o ka permafrost, e mea paʻakikī ana i nā holoholona ke loaʻa nā meaʻai na lākou.
Hoʻonui
ʻO ka amplitude o ke aniau Arctic kekahi o nā hōʻailona nui. Ma ka laulā, ke ana wela ma loko o ka makahiki mai + 5- + 10 a –40 kekelē Celsius. I kekahi manawa ma kekahi mau wahi he emi a i -50 kekelē. He paʻakikī kēlā ʻano no ke ola kanaka, no laila, ʻimi ʻepekema ka noiʻi a me ka unuhi ʻana o nā mea maka ma aneʻi.
Mahana
ʻO ka hapa nui o ka hoʻoilo i loko o ka ʻāpana aniau arctic. ʻO ke ana wela o ke ea he –30 kekelē Celsius. Pōkole ke kauwela, mau ia i kekahi mau lā i Iulai, a piʻi ka mahana o ka lewa i nā kekelē 0, hiki ke piʻi i + 5 kekelē, akā hiki hou mai nā hau. ʻO ka hopena, ʻaʻohe manawa o ka ea e mehana ai i loko o kahi wā pōkole o ke kauwela, ʻaʻole hehee nā glacier, ʻoiai, ʻaʻole loaʻa ka wela i ka honua. ʻO ia ke kumu i uhi ʻia ai ka moku ʻāina ʻo ʻAmelika me ka hau, a lana nā glaciers i loko o ka wai.
