Isimo sezulu esisezindaweni eziphansi komhlaba sibonakala ngamazinga okushisa aphansi, ubusika obude, imvula encane nezimo zokuphila ezingathandeki. Kodwa-ke, ngokungafani nesimo sezulu se-arctic, kukhona ihlobo lapha. Ngesikhathi saso esishisa kakhulu, umoya ungafudumala kuze kufike ku- + 15 degrees.
Izici zesimo sezulu esingaphansi komhlaba
Indawo enalolu hlobo lwesimo sezulu iba nezinguquko ezinkulu ekushiseni komoya kuya ngesizini. Ebusika, i-thermometer ingehla iye -45 degrees nangaphansi. Ngaphezu kwalokho, isithwathwa esibi singanqoba izinyanga ezimbalwa. Ehlobo, umoya ufudumala ufike kuma-degree ayi-12-15 ngaphezu kuka-zero.
Amaqhwa amakhulu abekezelelwa kalula ngabantu ngenxa yomswakama ophansi. Esimweni sezulu esingezansi komhlaba, imvula ayivamile. Ngokwesilinganiso, cishe ama-350-400 mm awe lapha ngonyaka. Uma kuqhathaniswa nezindawo ezifudumele, leli nani liphansi kakhulu.
Kumele kuqashelwe ukuthi inani lemvula lincike ekuphakameni kwensimu ethile ngaphezu kogu lolwandle. Indawo ephakeme, imvula iba ngaphezulu kuyo. Ngakho-ke, izintaba ezisesimweni sezulu esishisayo zithola imvula enkulu kunamathafa nokudangala.
Izimila endaweni engaphansi komhlaba
Akuzona zonke izitshalo ezikwazi ukusinda ebusika obude obunamakhaza angaphansi kwama-degree angama-40 kanye nehlobo elifushane elingenayo imvula. Ngakho-ke, izindawo ezinesimo sezulu esingaphansi komhlaba zibonakala ngezimbali ezilinganiselwe. Awekho amahlathi acebile futhi, ngaphezu kwalokho, awekho amadlelo anotshani obude. Kodwa-ke, inani eliphelele lezinhlobo liphezulu impela. Izitshalo eziningi zingubulembu, ubulembu, ubulembu, amajikijolo, utshani. Ehlobo, zinikeza ingxenye enkulu yamavithamini ekudleni kwezinyamazane nakwezinye izilwane ezidla utshani.

Izihlahla zeConiferous zakha isisekelo sehlathi. Amahlathi angohlobo lwe-taiga, aminyene impela futhi amnyama. Kwezinye izindawo, esikhundleni sama-conifers, kwethulwa i-birch encane. Ukukhula kwesihlahla kuhamba kancane futhi kungenzeka kuphela isikhathi esilinganiselwe - ngesikhathi esifudumele esifushane sasehlobo.

Ngenxa yemininingwane yesimo sezulu esisezindaweni eziphansi komhlaba ezindaweni ezinethonya layo, umsebenzi wezolimo ogcwele awunakwenzeka. Ukuthola imifino nezithelo ezintsha, kuyadingeka ukusebenzisa izakhiwo zokwenziwa ngokushisa nokukhanyisa.
Izilwane zesimo sezulu esingaphansi komhlaba
Izindawo ezithonywe yisimo sezulu esingaphansi komhlaba zibukeka zingafani ezinhlobonhlobo zezilwane nezinyoni. Izakhamizi ezijwayelekile zalezi zindawo yi-lemming, i-arctic fox, i-ermine, impisi, i-reindeer, isikhova esineqhwa, i-ptarmigan.

Inani lezinhlobo ezithile ngqo lincike ezimweni zezulu. Ngaphezu kwalokho, ngenxa yochungechunge lokudla, ukuguquguquka kwesibalo sezinye izilwane kuthinta inani lezinye.
Isibonelo esigqamayo ukungabi bikho kokuhlangana kwamaqanda esikhova esineqhwa ngesikhathi sokwehla kwenani lemammings. Kwenzeka ukuthi la magundane akhe isisekelo sokudla kwale nyoni edla inyama.
Izindawo Emhlabeni ezinesimo sezulu esingaphansi komhlaba
Lolu hlobo lwesimo sezulu lusabalele emhlabeni futhi luthinta amazwe amaningi. Izindawo ezinkulu kunazo zonke zitholakala eRussian Federation naseCanada. Futhi, indawo yesimo sezulu esingezansi komhlaba ifaka izindawo ezithile ze-USA, Germany, Romania, Scotland, Mongolia kanye neChina.
Ukwabiwa kwezindawo ngokuya ngesimo sezulu esikhona kunezinhlelo ezimbili ezivamile - i-Alisova neKeppen. Ngokuya ngabo, imingcele yezindawo inokuhluka okuthile. Kodwa-ke, noma ngabe kunjani ukwahlukana, isimo sezulu esisezindaweni eziphansi komhlaba sisebenza njalo ezingxenyeni ze-tundra, i-permafrost noma i-subpolar taiga.
