I Alaska, hoʻololi ke aniau mai ka moana a i ka subarctic, a lilo i pana. Ua hana kēia i nā mea kū i ke ʻano o ke aniau, ma muli o ke ʻano he ʻelima mau ʻāpana pae i hiki ke hoʻomaopopo ʻia. Aia kekahi wahi kahakai nui a me nā wai waiwai nui, nā kuahiwi a me nā wahi o permafrost.

Kahi āpana kai

Aia ka ʻaoʻao hema o ka peninsula ma ka ʻāpana kai moana, i hoʻohuli ʻia e ka aniau o ka Moana Pākīpika. Ua kuapo ʻia e kahi aniita kai e uhi ana i ka waena o Alaska. I ke kauwela, hoʻohuli ʻia ke aniau e nā lehulehu o ka lewa e hoʻopuni nei mai ka ʻāpana ʻo Bering Sea. Pā nā ʻenekini Continental i ka hoʻoilo.

Aia kekahi mahele hoʻololi ma waena o nā ʻano ʻĀinapuniole a me nā kai o ke aniau. Ua hoʻokumu ʻia kekahi mau kūlana anilā ma aneʻi, i hoʻopili ʻia e ka lehulehu o ka ʻaoʻao hema a me ka ʻākau i nā manawa like ʻole o ka makahiki. Uhi ka ʻāinapuniʻole i nā panalāʻau o Alaska. Aia ka ʻaoʻao ʻākau o ka peninsula ma ka ʻāpana kai o ka Arctic climatic. ʻO kēia kahi o ka Arctic Circle.

Ma ka laulā, ma Alaska, hāʻule kahi pae kiʻekiʻe o ka wai a me ka ua mai 3000 mm a 5000 mm i kēlā me kēia makahiki, akā kaulike ʻole ko lākou nui. Hāʻule ka hapa nui o lākou āpau i kahi o nā pali mauna, a ʻo ka mea liʻiliʻi loa ma kahakai ʻākau.

Inā mākou e kamaʻilio e pili ana i ke ʻano mahana o ke ʻano o Alaska, a laila ma ka awelika ʻokoʻa ia mai + 4 kekelē a i -12 kekelē Celsius. I nā mahina kau wela, hoʻopaʻa ʻia kahi mahana wela o +21 kekelē ma aneʻi. Ma ka ʻaoʻao kai, ʻo + 15 kekelē i ke kauwela, a ma kahi o -6 i ka hoʻoilo.

Ke aniau subarctic o Alaska

Aia nā ʻāina tundra a me nā ʻāina tundra-tundra i ke aniau subarctic. He pōkole loa ke kauwela ma aneʻi, ʻo ka hoʻomaka ʻana o ka hau e hoʻoheheʻe wale i ka hoʻomaka o Iune. Kū ka wela ma kahi o ʻekolu a ʻehā mau pule. Aia nā lā polar a me nā pō ma ʻō aku o ka Circle Arctic. Ma kahi kokoke i ka akau o ka peninsula, hoʻemi ka nui o ka ua i 100 mm o ka makahiki. I ka hoʻoilo, i ka wahi subarctic, hāʻule ka mahana i -40 kekelē. He lōʻihi loa ka hoʻoilo a ma kēia manawa ua paʻakikī ke aniau. Hāʻule ka heluna nui o ka ua i ke kauwela, ke piʻi ka mahana i kahi kiʻekiʻe o +16 kekelē. I kēia manawa, ke nānā ʻia nei ka mana o nā ea ea lōkahi ma aneʻi.

ʻO ke kūkulu ʻākau o ka ʻĀkau a me nā mokupuni e pili ana i kahi aniau arctic. Aia nā wao akua pōhaku me nā lichen, nā limu, a me nā aniani. Noho ka hoʻoilo i ka hapa nui o ka makahiki, a i kēia manawa hāʻule ka mahana i -40 kekelē. ʻAʻohe pili i ka ua. Eia kekahi, ʻaʻohe kauwela ma aneʻi, no ka mea piʻi iki ka mahana ma luna o 0 kekelē.
