Aia ʻo ʻAmelike ʻĀkau ma ka hemisphere komohana ʻākau o ka honua. Mai ka ʻĀkau a i ka hema ka ʻāina ākea no ʻoi aku ma mua o 7 tausani km, a aia ma nā wahi kai.
Ke aniau Arctic
Ma ke kahakai ʻākau o ka pae ʻāina, ma Greenland a me kahi ʻāpana o ka pae ʻāina ʻo Kanada, aia kahi aniau arctic. Ua hoʻomalu ʻia e nā wao nahele arctic i uhi ʻia me ka hau, a ulu nā laikini a me nā limu i nā wahi. Hoʻololi ka mahana hoʻoilo ma waena o -32-40 kekelē Celsius, a i ke kauwela ʻaʻole ia ma mua o +5 kekelē. Ma Greenland, hiki i nā hau ke hāʻule i lalo i -70 kekelē. I kēia aniau, pā mai ka makani polū a me ka makani maloʻo i nā manawa āpau. ʻAʻole i ʻoi aku ka nui o ka ua makahiki i ka 250 mm, a ʻo ka hau ka hapa nui.
Noho ke kāʻei subarctic iā Alaska a me ka ʻākau o Kanada. I ka hoʻoilo, neʻe ka poʻe lewa mai ka Arctic a lawe mai i nā hau hau ʻino. I ke kauwela, hiki i ka mahana ke piʻi aʻe i + 16 kekelē. ʻO ka hoʻoulu makahiki 100-500 mm o. He akahai ka makani ma aneʻi.
Aniau mahana
Uhi ʻia ka hapa nui o ʻAmelika Hema e kahi aniau akahai, akā ʻokoʻa ke ʻano o ke aniau i nā wahi like ʻole, kaukaʻi ʻia. E hoʻokaʻawale i kahi kai ma ke komohana, ma waena konakona - ma ka hikina a me ka ʻāinapuniʻole - i waenakonu. Ma ka ʻaoʻao komohana, hoʻololi iki ka mahana i ka makahiki, akā hāʻule ka nui o ka ua ma aneʻi - 2000-3000 mm o ka makahiki. Ma ka hapa waena, pumehana nā kauwela, anuanu ka hoʻoilo, a me ka ua awelika. Ma ke kai hikina, anuanu ke anuanu a wela ʻole ke kauwela, me kahi o 1000 mm o ka ua i kēlā me kēia makahiki. ʻAno like ʻole nā ʻone kūlohelohe ma aneʻi: taiga, steppe, nā ulu ulu a deciduous.
Ma ka ʻāpana subtropical, e uhi ana ma ka hema o ʻAmelika Hui Pū ʻIa a me ka ʻākau o Mekiko, nā anuanu a me nā aniani kokoke e hāʻule ma lalo o 0 kekelē. I ka hoʻoilo, hoʻomalu ka ea mahana wela, a i ke kauwela, ka ea wela maloʻo. I kēia wahi anilā he ʻekolu mau ʻāina: ua hoʻololi ʻia ke anilā subtropical e ka Mediterranean a me ka monsoon subtropical.
Ke aniau pākea
Uhi ʻia kahi ʻāpana nui o ʻAmelika Hui Pū ʻIa e kahi aniau tropical. Ma ka ʻāina āpau, hāʻule nā nui o ka ua ma aneʻi: mai 250 a 2000 mm o kēlā me kēia makahiki. ʻAʻohe manawa anuanu ma aneʻi, a noho aliʻi ke kauwela kokoke i nā manawa āpau.
ʻO kahi ʻāpana liʻiliʻi o ka ʻāina ʻAmelika ʻAkau e noho ʻia e ka ʻāpana aniau subequatorial. Wela ma aneʻi i nā manawa āpau, ka ua i ke kauwela i ka nui o 2000-3000 mm o ka makahiki. Aia i kēia aniau nā ululāʻau, nā savannas, a me nā ulu lāʻau.
Loaʻa ʻo ʻAmelike ʻĀkau i nā wahi kai āpau, koe wale nō ke kāʻei kaulike. Ma kauwahi e ʻike ʻia kahi hoʻoilo, kauwela wela, a ma kekahi mau wahi o ka aniau i ka makahiki i aneane ʻike ʻole ʻia. Hoʻopili kēia i ka like ʻole o nā flora a me nā holoholona ma ka ʻāina nui.
