INyakatho Melika ilele enkabazwe esentshonalanga yeplanethi, futhi ukusuka enyakatho kuya eningizimu izwekazi lihlala ngaphezu kwamakhilomitha ayizinkulungwane eziyi-7. Izwekazi linezimbali nezilwane ezahlukahlukene ngenxa yokuthi lilele cishe kuzo zonke izindawo zezulu.
Isimo sezulu saseNyakatho Melika
Isimo sezulu se-Arctic sibusa ngobukhulu be-Arctic, iziqhingi zaseCanada naseGreenland. Kukhona izingwadule zase-arctic ezinamakhaza amakhulu nemvula encane. Kulezi zindawo, izinga lokushisa lomoya kuyaqabukela liphakeme kunama-zero degrees. Ngaseningizimu, enyakatho yeCanada nase-Alaska, isimo sezulu asithambile, ngoba ibhande le-arctic lithathelwa indawo yangaphansi komhlaba. Izinga lokushisa eliphakeme ehlobo lingu- + 16 degrees Celsius, kanti ebusika kunamazinga okushisa angama- –15–35 degrees.
Isimo sezulu esipholile
Ingxenye enkulu yezwekazi ilele esimweni sezulu esipholile. Izimo zezulu zolwandle i-Atlantic nePacific ziyehluka, njengoba kunjalo nangesimo sezulu kuleli zwekazi. Ngakho-ke, kuyisiko ukuhlukanisa isimo sezulu esipholile sibe empumalanga, maphakathi nasentshonalanga. Le nsimu enkulu inezindawo zemvelo eziningana: i-taiga, ama-steppes, amahlathi ahlanganisiwe nalawo anqunyiwe.
Isimo sezulu esishisayo
Isimo sezulu esishisayo sizungeze i-United States eseningizimu nenyakatho yeMexico, futhi sihlanganisa indawo enkulu. Imvelo lapha yehlukile: amahlathi ahlala eluhlaza futhi axubekile, amahlathi asemaqeleni namathafa, amahlathi ahlukahlukene anomswakama nezingwadule. Futhi, isimo sezulu sithonywe yizinkumbi zomoya - izulu elomile lamazwekazi nezimvula. I-Central America imbozwe izingwadule, ama-savanna, namahlathi ahlukahlukene anomswakama, futhi le ngxenye yezwekazi ilele endaweni eshisayo yesimo sezulu.
Iningizimu esezingeni eliphakeme yeNyakatho Melika ilele ngebhande le-subequatorial. Kukhona ihlobo elishisayo nobusika lapha, izinga lokushisa lama- + 20 degrees ligcinwa cishe unyaka wonke, futhi kunemvula eningi - kufika ku-3000 mm ngonyaka.
Kuyathakazelisa
Asikho isimo sezulu esisenkabazwe eNyakatho Melika. Le ukuphela kwendawo yesimo sezulu engekho kuleli zwekazi.
