Ukushisa endaweni ethile kuthonywa izici ezifana nokuphakama ngaphezu kwezinga lolwandle, ukusondela kolwandle kanye nesimo esivela ku-equator.
©Peter DelaneyENingizimu Afrika, izinga lokushisa eliphansi kakhulu litholakala ezindaweni eziphakeme kakhulu nezintaba, kodwa lokhu kungathonywa ezinye izici.
Uma zonke ezinye izici zilingana, izinga lokushisa lomoya linciphisa ngokuphakama okwandayo ngaphezu kwezinga lolwandle; isib. izinga lokushisa liyehla, njengoba uya phezulu.
Isilinganiso se -6.5ºC nge-1 000 m ukuphakama ekuphakameni ngokuvamile kubhekwa njenge 'standard'. Amanani avela ngaphansi -4.6ºC kuya phezulu ku-9ºC ngo-1000 m ukuphakama kokuphakama alotshiwe ezindaweni ezahlukene emhlabeni.
Zombili izindawo zibeke cishe cishe nge-latitude efanayo. Ugu lolwandle olumpumalanga luthonywe yilezi zinsuku ezifudumele zaseMozambique, i-tributary ye-Agulhas yamanje, kanti umkhuhlane waseBenguela wamanje unciphisa amazinga okushisa ogwini olusentshonalanga yeNingizimu Afrika.
Ezindaweni ezishisayo zenyakatho eLimpopo, izinga lokushisa eliphezulu nomoya omile ngoSeptemba nasekuqaleni kuka-Okthoba kunemiphumela emibi kakhulu etizini ekhulile kule ndawo. Lesi yisici esibalulekile sokucabangela lapho ukhula ezinye izitshalo ngaphansi kokunisela kule ndawo.
Phakathi nezinyanga zasebusika, ingaphakathi elingaphakathi yezwe, ikakhulukazi i-Free State, liye lawa njalo ngezimo ezibandayo. Lezi zomoya ezinqamule zivela eningizimu kuya eningizimu-mpumalanga lapho iqhwa ezintabeni zase-Eastern Cape naseLesotho.
Ukuphakama Nokushisa
Uma zonke ezinye izici zilingana, izinga lokushisa lomoya linciphisa ngokuphakama okwandayo ngaphezu kwezinga lolwandle; isib. izinga lokushisa liyehla, njengoba uya phezulu.
Isilinganiso se -6.5ºC nge-1 000 m ukuphakama ekuphakameni ngokuvamile kubhekwa njenge 'standard'. Amanani avela ngaphansi -4.6ºC kuya phezulu ku-9ºC ngo-1000 m ukuphakama kokuphakama alotshiwe ezindaweni ezahlukene emhlabeni.
Ulwandle Nokushisa
Uma uqhathanisa izinga lokushisa lokushisa emoyeni ngasempumalanga nasentshonalanga yeNingizimu Afrika, uzobona umphumela wamanzi e-ocean ekushiseni kwemoya. Ukushisa okuvamile kwe-air eThekwini ogwini olusempumalanga ngu-21ºC kanti ukushisa kwePort Nolloth ogwini olusentshonalanga kuyinto engu-14.2ºC.Zombili izindawo zibeke cishe cishe nge-latitude efanayo. Ugu lolwandle olumpumalanga luthonywe yilezi zinsuku ezifudumele zaseMozambique, i-tributary ye-Agulhas yamanje, kanti umkhuhlane waseBenguela wamanje unciphisa amazinga okushisa ogwini olusentshonalanga yeNingizimu Afrika.
Ukwehla Nokushisa
Umthamo we-slope unomthelela omkhulu emazingeni okushisa ajwayelekile nsuku zonke ikakhulukazi ezindaweni ezinamapula aphansi nezintaba ezikhukhumezayo. ENingizimu Afrika, ama-slope aphakathi nenyakatho aphakathi nendawo anamazinga aphezulu okushisa kunemithangala eseningizimu.Ukushisa Namafu
Ezindaweni ezishisayo, ikhava yefu ithinta izikhathi zokushisa zonyaka. Imvula iyasebenza njenge-co-factor. Umkhuba jikelele wukuthi izinga lokushisa eliphakeme kunazo zonke endaweni evele ngaphambi kokuba izimvula zasehlobo ziqale. Izindawo ezinjalo zinehlobo elipholile elomile, elishisayo elomile kanye nehlobo elifudumele.Ezindaweni ezishisayo zenyakatho eLimpopo, izinga lokushisa eliphezulu nomoya omile ngoSeptemba nasekuqaleni kuka-Okthoba kunemiphumela emibi kakhulu etizini ekhulile kule ndawo. Lesi yisici esibalulekile sokucabangela lapho ukhula ezinye izitshalo ngaphansi kokunisela kule ndawo.
Ukushisa Nomoya
ENingizimu Afrika, imimoya ehlukahlukene inezimo ezinkulu kakhulu ekushiseni kwemoya. Okubaluleke kakhulu kulawa yizinto ezishisa kakhulu, ezomile kakhulu 'zezingulube ezinamandla', ezithinta indawo eshisayo, eyomile yangaphakathi ngaphansi kwe-escarpment ezindaweni ezingasogwini ngesikhathi sehlobo. Izindawo ezisogwini olusentshonalanga njenge-Olifants River Valley, iVredendal, kanye nezindawo zaseNtshonalanga Kapa, kungenzeka ukuthi zishaywa kakhulu yizingulube. Izindawo ezixilisiwe ezigodini zomfula zaseMpumalanga Kapa nazo zithonywa kakhulu yizingulube zeberg.Phakathi nezinyanga zasebusika, ingaphakathi elingaphakathi yezwe, ikakhulukazi i-Free State, liye lawa njalo ngezimo ezibandayo. Lezi zomoya ezinqamule zivela eningizimu kuya eningizimu-mpumalanga lapho iqhwa ezintabeni zase-Eastern Cape naseLesotho.
