Nyengo subarctic: makhalidwe, mbali ndi zimasintha wa anthu

Subarctic nyengo - ndi mtundu winawake wa nyengo, womwe ndi umodzi wa mabacteria dziko ndi nyengo. Mwachirengedwe ili pafupi ndi North Pole. mtundu wa kusintha pakati pa zinthu ozizira Arctic ndi yabwino zolimbitsa nyengo. Subarctic nyengo umalamulira mu kumpoto kwa dziko lapansi, ndi South pa ufulu chomwecho ndi boma linakwanitsa.

Anafotokoza lamba amathamanga limodzi kumpoto Canada, Alaska Peninsula, Gombe kum'mwera kwa Greenland, mbali wakumpoto wa Iceland, ndi Scandinavia Peninsula, Far East ndi Siberia.

Kaperekedwe nyengo

• subarctic nyengo ali ofala: lili nyengo yake yaitali ndi yotenthera yochepa (nthawizina kwina palimodzi).
• The ulamuliro wa zowononga pa chaka (kozizira, Siberia ndi North America yozizira, nthawi zonse m'malo mnzake).
• Kutentha pazipita mwezi lotentha kwambiri +15 ° C.
• Chaka chonse frosts zitheka. M'nyengo yozizira, ndi thermometer makamaka kusonyezedwa -5 ° C mu zilumba ndi -40 ° C kumtunda.
• The otsika mpweya kutentha si ladzala ndi chinyezi, inatuluka mpweya wa zone nyengo ndi laling'ono kwambiri. Iwo adzagwa makamaka m'chilimwe. Komabe, chifukwa kutentha otsika mvula akadali kuposa evaporation, ndipo izi zimakhudza dera madzi.
• M'nyengo yozizira, pamene mtengo kubwera kozizira misa mpweya adatchithisira kutentha. m'maiko Gouged, izo angafikire -60 ° C.
• Avereji chizindikiro kunja kutentha imasiyana malingana zone zachilengedwe ndi kutalikirana nyanja: a Titafika pamalo yotentha pafupifupi sizichitika, kutentha mu July salinso +12 ° C, ndi nyengo frosty yaitali, mpweya - zosakwana 300 mamilimita; mu zone nayonso wa ukuwonjezeka mpweya 400 mamilimita / chaka, akuonekera bwino, ngakhale sakhalitsa, koma chilimwe nyengo.
• Usiku kumalo ozizira ndi kutalika otsika dzuwa masana amaperekedwa pa dera la cheza bwino zoipa, ndipo izi zimakhudza zonse ozizira chimapangitsa pamwamba. Ngakhale nyengo magwiridwe kutentha kwa masiku angapo, nthaka komabe si nthawi konzekera.

mitundu

Subarctic nyengo lagawidwa mitundu 4 chachikulu. Muyezo waukulu ndi kusiyana yonyowa ozizira chizindikiro (Köppen gulu):

• DWC - ozizira amtengo nyengo ndi nyengo youma;
• dwd - ozizira youma nyengo frosts kwa -40 ° C;
• dfc - ozizira amtengo nyengo ndi chinyezi yunifolomu;
• dfd - ozizira amtengo nyengo ndi kutentha otentha mpaka + 20 ° C.

Features

Subarctic mtundu nyengo linapanga eponymous zachilengedwe lamba Hrs ndi malo achilengedwe Titafika pamalo ndi Titafika pamalo nkhalango.

Cold mzati (kutentha wotsikitsitsa) anali mayina a Republic Saha (Yakutia), mu. Oymyakon. Pali nyengo subarctic kwambiri makamaka: kutentha wotsikitsitsa unali wolunjika pa kuzungulira -71 ° C. Avereji yozizira kutentha Oimyakon Valley - -50 ° C. Kudera limeneli imatengedwa kumpoto kwenikweni kumene kuli dera la dziko.

moyo wa munthu

Izi mtundu wa nyengo ndi akumane kuti anthu akhalemo. nyengo ndi kwakuti kupulumuka zovuta okwanira mu malo awa. Komabe, moyo m'madera amenewa alipo. Mbiri anthu a anthu amene ndinazolowera zikhalidwe za mtundu winawake wa nyengo (ecotypes). Mmodzi wa yaikulu ndi Arctic dziphunzitsiranso mtundu. Izi ndi anthu amene amakhala mkati kozizira ndi mabacteria subarctic nyengo.

Ngati anthu moyo mpaka kalekale ku Arctic simungathe, ndiye moyo mu subarctic zotheka. Chinthu chokha kuona: lili peculiarities yake. Anatengera anthu kwa nyengo subarctic, pamafunika yaitali ndithu ndi zovuta. M'dera la Madzi oundana ndi nthaka mazira zovuta nyumba, makamaka m'tawuni.

Munthu nyengo komanso zimawononga: okhazikika ozizira frosts chisanu ndi thupi pansi chimfine pafupipafupi matenda ena tizilombo, ndipo nthawi yaitali wa usiku kumalo ozizira m'mavuto wamanjenje dongosolo.

N'chiyani chimachititsa moyo wa munthu akuchita zimenezi?

moyo wa munthu mu zone ya subarctic zikudalira pa chikhalidwe: Mwachidule yotentha anthu kusonkhanitsa zipatso, bowa ndi zitsamba. Nayonso lili ndi masewera ndi nyama zina za m'madzi wolemera mu nsomba.

Zochita za nyengo kum'mwera kwa Arctic momveka bwino kuti kulima mbewu wotere nthawi zina tikhoza kusangalatsa, koma nthawi zina - Zingatikhumudwitse. kuchuluka kwa chakudya si chinthu zonse, kukolola wolemera chilimwe mwina amasinthidwa pa Taphunzira yozizira. Pachifukwa ichi, malire a lamba subarctic chosamanga lalikulu mafakitale m'mizinda, anthu amakhala kumidzi ochepa, amene angathe kuzidyetsa wokha.

M'zaka zaposachedwapa, anthu amakonda otsutsana zachilengedwe, ndi kuti anali zinkaoneka ngati zosatheka poyamba, tsopano kukhala chenicheni. Mkulu umisiri kuthandiza kuthetsa vuto yomanga nyumba oyenera kukhala mu zigawo izi wouma mtima, ndi kuthekera zoyendera mwadzidzidzi amapatsa anthu a kumpoto ndi mankhwala kuti iwo Mwachidule kotunga (zipatso, masamba).

Pakufunika zitsanzo za anatengera anthu nyengo subarctic? Anthu okhala m'dera limeneli, anakakamizika kubala chakudya chawo ndi kugula zovala ofunda. Chukchi ndi Nenets ndi zinthu zikopa mphalapala ndi tsitsi. Ukugwira kusaka kapena kusodza kuzidyetsa wokha.

M'dera lino zilumba kum'mwera a Nyanja Barents, madera ena a Russia: Western Siberia, kumpoto-kum'mawa ndi East European Plain.
