Uhlobo lwesimo sezulu se-arctic lujwayelekile ensimini yamabhande e-arctic nase-subarctic. Kukhona into efana nobusuku be-polar, lapho ilanga lingabonakali ngaphezu komkhathi isikhathi eside. Ngalesi sikhathi, akukho ukushisa okwanele nokukhanya.
Izici zesimo sezulu se-Arctic
Isimo sezulu se-Arctic siyizimo ezinzima kakhulu. Lapha kuphela ngezikhathi ezithile zonyaka izinga lokushisa likhuphuka ngaphezu kuka-zero, kulo lonke unyaka - isithwathwa. Ngenxa yalokhu, kwakheka izinguzunga zeqhwa lapha, futhi ingxenye yezwekazi elikhulu limboze iqhwa. Kungakho lapha kwakhiwe umhlaba okhethekile wezitshalo nezilwane.
Imininingwane
Izici eziyinhloko zesimo sezulu se-arctic:
- ubusika obubanda kakhulu;
- ihlobo elifushane nelipholile;
- umoya onamandla;
- imvula yehla kancane.
Ukuzikisa
Indawo yesimo sezulu se-Arctic ihlukaniswe yaba izinhlobo ezimbili. Endaweni yohlobo lwezwekazi, cishe imilimitha eyi-100 yemvula yehla ngonyaka, kwezinye izindawo - 200 mm. Esifundeni sesimo sezulu sasolwandle, imvula yehla kakhulu. Iningi leqhwa liyawa, futhi ehlobo kuphela, lapho izinga lokushisa likhuphuka laya ku-0 degrees Celsius, lina.
Indawo yesimo sezulu se-arctic
Isimo sezulu se-Arctic sijwayelekile ezifundeni eziphakeme. ENingizimu Nenkabazwe, lolu hlobo lwesimo sezulu luvamile endaweni yezwekazi i-Antarctic. Ngokuqondene nenyakatho, ihlanganisa i-Arctic Ocean, emaphethelweni eNyakatho Melika nase-Eurasia. Nali ibhande lemvelo lezingwadule zase-arctic.
Izilwane
Izilwane endaweni yesimo sezulu se-arctic zimbi kakhulu, ngoba izinto eziphilayo kufanele zivumelane nezimo ezinzima. Izimpisi zasenyakatho nolamula, izinyamazane zaseNew Zealand nezimpungushe ezibandayo zihlala endaweni yamazwekazi naseziqhingini. Kunabantu abaningi bezinkabi ze-musk eGreenland. Esinye sezakhamuzi zendabuko zesimo sezulu se-Arctic ibhere elisendaweni emhlophe. Uhlala emhlabeni futhi uyabhukuda emanzini.
Izwe lezinyoni limelelwa izikhova ezibandayo, ama-guillemots, ama-eider, ama-rosy gulls. Kunemihlambi yezimpawu nezikhonkwane ogwini. Ukungcola komkhathi, i-World Ocean, ukuncibilika kwezinguzunga zeqhwa, ukufudumala kwembulunga yonke kunomthelela ekwehleni kwesibalo sezilwane nezinyoni. Ezinye izinhlobo zivikelwe izifundazwe ezahlukahlukene. Ngenxa yalokhu, izinqolobane zikazwelonke nazo ziyakhiwa.
Izimila
Izimbali ze-tundra ne-desert esimweni sezulu se-arctic zimbi. Azikho izihlahla lapha, kuphela izihlahlana, utshani, ubulembu nobulembu. Kwezinye izindawo, ehlobo, ama-poppies ase-polar, i-bluegrass, i-alpine foxtail, i-sedge, nezinhlamvu ziyakhula. Izimila eziningi zingaphansi kweqhwa, okwenza kube nzima ngezilwane ukuzitholela ukudla.
Ubungako
Ukuphakama kwesimo sezulu se-Arctic kungenye yezinkomba eziyinhloko. Ngokuvamile, izinga lokushisa unyaka wonke lisuka ku- + 5- + 10 kuya -40 degrees Celsius. Kwesinye isikhathi kwezinye izindawo kunokuncipha okufika ku -50 degrees. Izimo ezinjalo zinzima empilweni yomuntu, ngakho-ke kwenziwa ucwaningo lwesayensi nokukhishwa kwezinto zokusetshenziswa ikakhulukazi.
Ithempelesha
Ubusika obuningi buhlala endaweni yesimo sezulu se-arctic. Izinga lokushisa lomoya elingu- 30 degrees Celsius. Ihlobo lifushane, lihlala izinsuku ezimbalwa ngoJulayi, kanti izinga lokushisa lomoya lifinyelela kuma-degree angama-0, lingafinyelela kuma-degree ama-5, kepha maduzane amakhaza abuya futhi. Ngenxa yalokho, umoya awunaso isikhathi sokuzifudumeza ngesikhathi esifushane sasehlobo, izinguzunga zeqhwa azincibiliki, ikakhulukazi njengoba umhlaba ungakutholi ukushisa. Yingakho indawo yezwekazi imbozwe yiqhwa, futhi izinguzunga zeqhwa zintanta emanzini.
