Nyengo yam'madzi otentha imakhala ndi kutentha pang'ono, nyengo yayitali, mvula yambiri komanso moyo wosasangalatsa. Komabe, mosiyana ndi nyengo yozizira, kuno kuli chilimwe. Nthawi yotentha kwambiri, mpweya umatha kutentha mpaka madigiri 15.
Makhalidwe anyengo yakutentha
Dera lomwe lili ndi nyengo yamtunduwu limasintha kwambiri kutentha kwa mpweya kutengera nyengo. M'nyengo yozizira, thermometer imatha kutsika mpaka -45 madigiri ndikutsika. Komanso, chisanu cholimba chimatha kulamulira kwa miyezi ingapo. M'chilimwe, mpweya umawotha mpaka madigiri 12-15 pamwamba pa zero.
Kutentha kwambiri kumalolera mosavuta anthu chifukwa chinyezi chochepa. M'nyengo yotentha kwambiri, mvula imagwa kawirikawiri. Pafupifupi, pafupifupi 350-400 mm imagwera kuno pachaka. Poyerekeza ndi madera otentha, mtengowu ndiwotsika kwambiri.
Tiyenera kudziwa kuti kuchuluka kwa mpweya kumadalira kutalika kwa gawo linalake pamwambapa. Malo okwezekawo, ndi omwe amagwa mvula yambiri. Chifukwa chake, mapiri omwe amakhala m'malo otentha kwambiri amalandira mvula yambiri kuposa zigwa ndi malo ogumuka.
Zomera m'malo otentha kwambiri
Sizomera zonse zomwe zimatha kupulumuka nthawi yayitali yozizira ndi chisanu pansi pa 40 madigiri komanso chilimwe chochepa popanda mvula. Chifukwa chake, madera okhala ndi kotentha kotentha amadziwika ndi zomera zochepa. Kulibe nkhalango zolemera komanso, kulibe madambo okhala ndi udzu wamtali. Komabe, mitundu yonse ya zamoyo ndiyokwera kwambiri. Zomera zambiri ndizokoma, ndere, ndere, zipatso, udzu. M'chilimwe, amapereka gawo lalikulu la mavitamini pazakudya za agwape ndi zitsamba zina.

Mitengo ya Coniferous imapanga maziko a nkhalango. Nkhalangoyi ndi yamtundu wa taiga, yolimba kwambiri komanso yamdima. M'madera ena, m'malo mwa conifers, amamera birch. Kukula kwa mitengo kumakhala kochedwa kwambiri ndipo kumatheka kokha kwakanthawi kochepa - nthawi yayitali yotentha.
Birch wachinyamata
Chifukwa chodziwika ndi nyengo yakumadzulo kwa madera omwe ali ndi mphamvu zake, ntchito zonse zaulimi ndizosatheka. Kuti mupeze ndiwo zamasamba ndi zipatso, pamafunika kugwiritsa ntchito zinthu zopangira kutentha ndi kuyatsa.
Zinyama zam'mlengalenga
Madera omwe amakhudzidwa ndi nyengo ya kum'mwera kwenikweni samasiyana paminyama ndi mbalame zosiyanasiyana. Omwe amakhala m'madela awa ndi lemming, nkhandwe, armine, nkhandwe, mphalapala, kadzidzi wachisanu, ptarmigan.

Chiwerengero cha mitundu ina mwachindunji chimadalira nyengo. Kuphatikiza apo, chifukwa cha chakudya, kusinthasintha kwa ziweto zina kumakhudza ena.
Chitsanzo chochititsa chidwi ndi kusowa kwa nkhwangwa za mazira mu kadzidzi wachisanu pakuchepa kwa kuchuluka kwa mandimu. Zimachitika kuti makoswewa amapanga maziko azakudya za mbalame yodyerayi.
Malo Padziko Lapansi okhala ndi nyengo yozizira
Nyengo yamtunduwu ikufalikira padziko lapansi ndipo imakhudza mayiko ambiri. Madera akulu kwambiri ali ku Russian Federation ndi Canada. Komanso, madera ozungulira kotentha akuphatikizapo madera ena a USA, Germany, Romania, Scotland, Mongolia komanso China.
Kugawidwa kwa madera kutengera nyengo yomwe ili pano kuli njira ziwiri zofananira - Alisova ndi Keppen. Malingana ndi iwo, malire a madera ali ndi kusiyana. Komabe, mosasamala kanthu za magawanowa, nyengo yakum'mwera kwenikweni imagwira ntchito m'malo amtundra, permafrost kapena subpolar taiga.
