Isimo Sezulu kanye Nemvula eNingizimu Afrika
INingizimu Afrika yindawo eshisayo, eyomile, enesimo sezulu esiphezulu esingaphezu kwamaphesenti angama-65 endaweni engaphansi kuka-500 mm. Le mvula ibhekwa njengomkhawulo ophansi wokukhiqizwa kwezitshalo eziphumelelayo. Izitshalo eziningana zinemvula ephakeme kakhulu, njengemifula yetiyi edingeka ngaphezu kuka-1 000 mm ngonyaka.Imvelo yemvula eNingizimu Afrika idinga ukuchelela ngisho nasezindaweni zokulima ngenemvula ephakeme yaminyaka yonke. Isibonelo sokuthi izitshalo ezivuthiwe eCeres eWestern Cape. Izitshalo ziphuziswa ngesikhathi sehlobo olomile njengoba le ndawo ithola imvula ephakeme yaminyaka yonke ebusika.
Ngenxa yokuthi iNingizimu Afrika yileli zwe elishisayo, elomileyo isilinganiso sokulahlekelwa kwamanzi ngonyaka ngokukhuphuka kuphezulu futhi kwandisa isidingo samanzi okunisela.
Iyini iSimo Sezulu Ngokubanzi?
Isimo sezulu ngokubanzi isho isimo sezulu ngesilinganiso sezwe noma sezwe. Izindawo ezinkulu ezinezimo ezifanayo zezimo zihlelwe ndawonye futhi zichazwe emephini. Lezi zingaba izigaba ngokusekelwe ezinhlobonhlobo zemingcele yezulu efana nezindawo zezulu zakwaKöppen.Ukuhlukaniswa kwesimo sezulu saseKöppen kuhlukanisa izimo ezinhlanu zibe yizinhlobo ezinkulu ezinhlanu, ezimelelwe izinhlamvu ezinkulu A, B, C, D no-E. Isibonelo A sishisa futhi i-E iyisipula.
Kuyini iMeso-Isimo Sezulu?
I-Meso-sezulu isho isimo sezulu esendaweni. Izinhlobo eziningana ze-meso-climates zingatholakala ngaphakathi kwesimo esithile se-macro-sezulu.Izimo zezulu ze-meso-climates kanye nokusatshalaliswa kwazo ezindaweni eziningi zivame ngokuyinhloko ngokudweba indawo. I-Topography ihlanganisa izici ezifana nezigodi, izintaba nemifula.
Izimo zeMeso ezizungeze iMagaliesberg, egijima empumalanga nasentshonalanga ePitoli edlule eRustenburg inikeza isibonelo esihle kakhulu. Izindebe ezisemaphandleni ezisenyakatho zentaba zifudumala kakhulu kunezintambo zomphakathi ezingaseningizimu. Lawa ke ama-two-climates ahlukene.
Izindebe ezisenyakatho zibhekene nelanga futhi isixuku esithile semisebe yelanga sifike endaweni encane kakhulu, ngaleyo ndlela sinikeze ukushisa okwengeziwe endaweni ngayinye.
Izindebe ezisenyakatho zaseMagaliesberg zineqhwa futhi zinezinga lokushisa eliphakeme unyaka wonke ezifanele izitshalo ze-citrus nezamaxhaphozi ngaphansi kokunisela. Nokho, izintaba ezisezintanjeni ezingezansi, zinezulu ehluke ngokuphelele kusukela emathafeni aphakathi. Lapha, ubusika bubanda futhi iqhwa kwenza le ndawo ingakulungeli izitshalo ezingaphansi komhlaba.
Iyini Micro-Isimo Sezulu?
Kwemikhawulo yezinkanyezi ngokuvamile kuvame ukubonakala okuhambisana nezindawo ezincane.Ukunisela kuvame ukusetshenziselwa ukuguqula i-micro-climatic: insimu eceliwe endaweni enomile noma eyomile ihluke kakhulu kunesimo sezulu esendaweni engazange isetshenziswe, ikakhulukazi ezindaweni ezigwadule.
