Siyaqhubeka nokubuyekezwa kwezinhlobo ezahlukahlukene zamafu ahlelwe yi Inhlangano Yezwe Yezulu (WMO). Kulesi senzakalo siqala ukuhlaziya amafu aphakathi nendawo futhi sizoqala ngokuchaza izici, izakhi zofuzo nezinye izinto ezibanga ukwazi I-Altocumulus.
Lolu hlobo lwamafu luchazwa njengebhange, ungqimba oluncane noma ungqimba lwamafu amhlophe noma mpunga, noma womabili amhlophe nampunga, anezithunzi ezakhiwe ngamathayili, uquqaba oluyindilinga, ama-roller, njll. ukusabalalisa futhi lokho kungahle kuhlangane noma kungahlangani; iningi le- izakhi ezincane zisatshalaliswa njalo, zinobubanzi obubonakalayo phakathi kuka-1º no-5º.
Imvamisa zenziwa ngamaconsi amanzi. Lapho izinga lokushisa liphansi kakhulu, kwakheka amakristalu eqhwa. Uhlobo lwayo luzoba kanjena, lapho umoya omkhulu, osunduzwa ngohlelo olungaphambili, ukhuphukela emazingeni aphakathi (4-6Km.) Futhi ngemuva kwalokho uyajiya. Ngokulandelayo, lawa mafu akhiwa ngu izindimbane zomoya ezingazinzile, ebanikeza ukubukeka kwabo kwe-cumuliform. Imvamisa ziyingxenye yemingcele ebandayo nezindawo ezifudumele. Kulokhu kokugcina axubene ungqimba olulodwa ne-Altostratus, ehlala ezinkulungwaneni zamakhilomitha-skwele ayizinkulungwane.
Mayelana nokuthi basinikeza yini izinkomba mayelana nesimo sezulu esizayo, kuyaziwa ukuthi abakude bodwa babonisa isimo sezulu esihle. Ngakolunye uhlangothi, uma zibonakala zanda noma zixubene ne-Altostratus, zikhomba ifayela le- ukusondela ngaphambili noma isiphepho. Kulezi zimo zingakhipha imvula. Akufanele zididaniswe neCirrocumulus, i-Altocumulus inkulu, hhayi iStratocumulus, ngoba i-Altocumulus incane.
Ukuthwebula lawa mafu kuhle ukuthi ilambu langemuva, njengasesithombeni esikhulu, bakhombisa ukubukeka okwesabekayo. Ngezikhathi zasekuseni noma zantambama imininingwane yayo iyaziswa kangcono. Ngamalensi e- "Wide Angle" athathwa ngobukhulu bawo. Ekushoneni kwelanga, baba bomvu okwesikhashana.
I-Altocumulos ingenzeka ku- Izinhlobo ezi-4 (Stratiformis, Lenticularis, Castellanus noFloccus) futhi Izinhlobo ezingama-7 (I-Translucidus, iPerlucidus, i-Opacus, iDuplicatus, i-Undulatus, iRadiatus, iLacunosus).
