Izici eziyinhloko zesimo sezulu se Canada ubukhulu be-latitude, ukuvimba imimoya yasentshonalanga enqamula ezintabeni iRocky endaweni yase-Alberta, kanye Columbia EBrithani, ukumiswa kwenqwaba yezwekazi etholakala ebangeni eliphakeme kakhulu nebanga ukupholisa okukhulu ebusika, nokusondela koLwandle i-Arctic oluphola kakhulu ehlobo. Isimo sezulu saseCanada sibonakaliswa ubusika obubandayo namakhaza apholile noma amancane, anomswakama usuku lonke.
El Isimo sezulu futhi i amazinga okushisa Kodwa-ke, ziyahlukahluka kakhulu ngokuya ngezifunda, yingakho inyakatho inesimo sezulu esisezindaweni ezibandayo, inkangala inesimo sezulu esine-amplitude eqinile yokushisa kusuka kwesinye isizini kuye kwesinye, ngenkathi inamandla futhi ilinganisela kakhulu entshonalanga, eBritish Columbia ngoba ukuhlasela komoya wase-Arctic kuvinjelwe yi Kunamadwala Abantu baseCanada. Ugu olusentshonalanga nesiQhingi saseVancouver ikakhulukazi sithokozela isimo sezulu sasolwandle, nobusika obumnene nobunemvula, ngenxa yethonya loLwandlekazi iPacific.
Incazelo ye- amazinga okushisa Izinga lokushisa lasebusika lenyanga lehla laya ku -15º C ngisho nasengxenyeni eseningizimu yezwe, futhi amazinga okushisa angama -40º C angafinyelelwa ngemimoya enamandla yeqhwa. Iqhwa lonyaka lingafinyelela ngamasentimitha angamakhulu ambalwa ngokwesilinganiso. Mayelana ne ehlobo, amazinga okushisa wangempela angakhuphuka aze afike ku-35 ° C noma ngisho naku-40 ° C ezinkangala zaseCanada.
La lokushisa Kuhlanganiswe nomswakama, kunikeza inkomba yomswakama ephakeme impela ehlobo engxenyeni esempumalanga yezwe. Enyakatho eyedlulele yezwe, amanye amadolobha angafinyelela emazingeni okushisa angama -50ºC ebusika. Amazinga okushisa e-Alberta, ngokwesibonelo, awavamile ukufika ku-5ºC ehlobo. Futhi, abanamandla imimoya i-glacial bangakwazi ukwehlisa izinga lokushisa ngaphansi kuka-60º C ngaphansi kuka-zero.
