North America ili kumpoto kwa dziko lapansi kumadzulo kwa dziko lapansi. Kontinentiyo imayambira kumpoto mpaka kummwera kuposa ma 7,000 km, ndipo ili m'malo ambiri anyengo.
Nyengo ya Arctic
Ku gombe lakumpoto kwa kontrakitala, ku Greenland ndi gawo lina lazilumba zaku Canada, kuli nyengo yozizira. Amayang'aniridwa ndi zipululu za arctic zokutidwa ndi ayezi, ndi mbewa ndi ntchentche zokula m'malo. Kutentha kwachisanu kumasiyana pakati -32-40 madigiri Celsius, ndipo nthawi yotentha sikadutsa +5 madigiri. Ku Greenland, chisanu chimatha kutsika mpaka -70 madigiri. Munthawi imeneyi, mphepo yamkuntho ndi youma imawomba nthawi zonse. Mpweya wamvula wapachaka sukupitilira 250 mm, ndipo kumakhala chipale chofewa.
Lamba wapansi panthaka amakhala ku Alaska ndi kumpoto kwa Canada. M'nyengo yozizira, magulu ampweya ochokera ku Arctic amasunthira kuno ndikubweretsa chisanu choopsa. M'chilimwe, kutentha kumatha kukwera mpaka +16 madigiri. Mpweya wapachaka ndi 100-500 mm. Mphepo pano ndiyapakati.
Nyengo yozizira
Ambiri aku North America amakhala ndi nyengo yotentha, koma malo osiyanasiyana amakhala ndi nyengo zosiyana, kutengera chinyezi. Gawani malo am'madzi kumadzulo, moyenerera kontinenti - kum'mawa ndi kontrakitala - pakati. Kudera lakumadzulo, kutentha kumasintha pang'ono chaka chonse, koma pamakhala mpweya wambiri - 2000-3000 mm pachaka. Pakatikati, nyengo yotentha imakhala yotentha, nyengo yozizira imakhala yozizira, komanso mvula yambiri. Ku gombe lakummawa, nyengo yachisanu imakhala yozizira ndipo nyengo yotentha siyotentha, pafupifupi mamilimita 1000 amvula chaka chilichonse. Zigawo zachilengedwe nazonso ndizosiyanasiyana: taiga, steppe, nkhalango zosakanikirana.
Kudera lotentha, lomwe limakhudza kumwera kwa United States ndi kumpoto kwa Mexico, nyengo yozizira ndiyabwino ndipo kutentha sikumatsika konse pansi pa madigiri 0. Mphepo yamkuntho yotentha imalamulira nthawi yachisanu, komanso nyengo youma yotentha nthawi yotentha. Pali madera atatu mdera lino lanyengo: nyengo yotentha yamakontinenti imasinthidwa ndi nyengo ya Mediterranean komanso yotentha.
Nyengo yotentha
Gawo lalikulu la Central America limakutidwa ndi nyengo yotentha. M'dera lonselo, mvula imagwa mosiyanasiyana: kuyambira 250 mpaka 2000 mm pachaka. Palibe nyengo yozizira pano, ndipo chilimwe chimalamulira pafupifupi nthawi zonse.
Kachigawo kakang'ono ka kontinenti yaku North America kumakhala malo ozungulira nyengo. Kumatentha kuno pafupifupi nthawi zonse, mvula yotentha mchaka cha 2000-3000 mm pachaka. Nyengo iyi ili ndi nkhalango, nkhalango, ndi nkhalango.
North America imapezeka m'malo onse anyengo kupatula dera la equatorial. Kwina kumatchulidwa kuti nyengo yozizira, yotentha chilimwe, ndipo m'malo ena kusinthasintha kwa nyengo mchaka sichimawoneka. Izi zimakhudza kusiyanasiyana kwa zinyama ndi zinyama kumtunda.
