I-Sewula Afrika iyinarha ethloga amanzi wezulu nge-Sub-tropics, izombelezwe malwandle ekungiwo adlala indima eqakathekileko ekuniseni izulu ngokuya kweenkathi zonyaka. Amalwandle athumela imimoya ebujameni bokuna kwezulu begodu abanemithelela mayelana neendlela zobujamo bezulu obungaraga ubujamo lobu buye phambili, namkha bususwe enarheni.
Ukwahlukana kokuna kwezulu kungabangela ekutheni kube namatjhuguluko ebujameni bemimoya yezulu engaphezulu (isib. Imimoya yelwandle) emalwandle azombelezileko, namkha umthelela wobujamo bezulu obukhulu njenge El Niño/La Niña, namkha ezenzweni ezenziwa mumuntu namkha ekuhlanganisweni kwazo zoke izenzo lezi. Nasitjhejisisa kuhle, sitjheja ukudlalwa kwendima malwandle abomakhelwana we-Indiya ne-Atlantiki mayelana nokuna kwezulu e-Sewula Afrika.
Hlaza kwesibhakabhaka: ngaphezulu 125% yokuna kwezulu elijwayelekileko
Hlaza kotjani: 75% kufikela ku 125% yokuna kwezulu elijwayelekileko
Umebhe (ngesinceleni) ukhombisa ukuna kwezulu kilesisikhathi.

Ukuswaphelisa
Kafitjhazana, ukwahlukahlukana kwemimoya yamalwandle angePhasafiki, Indiya ne Sewula ye-Atlantiki kuba nomthelela wokuna kwezulu eSewula Afrika. Lezi akuzizenzakalo ezibanga ukuna kwezulu okuhlukahlukeneko kwaphela ngalokho amatjhuguluko we SSTs angabonisa amatshwayo angehla namkha angaphasi kwesimedo sokuna kwezulu endaweni ezinabileko zenarha ngesikhathi seenkhathi zonyaka.
Nanyana kunjalo, nakuneminingwana efaneleko mayelana nemimoya yelwandle efakwe emakhompyutheni ngaphambi kobana kufike isikhathi esithile sonyaka, Iindlela zekhompyutha lezi kanengi zingakhombisa amatshwayo anembako wobujamo bezulu esikhathini esizako kobana sizakuba nezulu namkha isomiso. Ukuthuthukisa inembo elizako mayelana neendlela ezisetjenziswa yikhompyutha kumsebenzi oragela phambili eKorweni YoBujamo BeZulu yeSewula Afrika kunye nezinye iinhlangano zikarhulumende eziphathelene nobujamo bezulu kunye namayunivesithi ephasini mazombe begodu kuthenjelwe kibososayensi ekufumaneni lokho ekwenzeka ngamalanga emalwandle wephasini kunye nemimoya yakhona.
