Ukuqeda ukubuyekeza kwethu izinhlobo ezahlukahlukene zamafu Sikhuluma ngefu okungenzeka ligqame kakhulu nelithakazelisayo, sibhekisa ku- I-Cumulonimbus, uhlobo lwesibili lwamafu wokuthuthuka mpo, yize empeleni kungumphumela weqoqo elinentuthuko enkulu.
Ngokwe-WMO ichazwa njengefu elijiyile neliminyene, eline- ukuthuthukiswa mpo okukhulu, ngesimo sentaba noma imibhoshongo emikhulu. Ingxenye, okungenani ephezulu yayo, imvamisa ibushelelezi, inemicu noma inesitashi, futhi cishe ihlala isicabalele; le ngxenye ivame ukunwetshwa ngesimo se-anvil noma i-plume enkulu. Ngezansi kwesisekelo esimnyama kakhulu, amafu aphansi anezikhukhula nemvula noma izihlambi.
Njengoba sishilo, iCumulonimbus yisinyathelo esilandelayo sokuthuthuka, ekukhuphukeni kokuhlangana, kuye eCumulus Congestus, ngakho-ke, amafu entuthuko enkulu emile (iziqongo zivame ukuba phakathi kwamakhilomitha ayisishiyagalombili kuya kwayi-8 ukuphakama). Ezingxenyeni zethu zivela ikakhulu entwasahlobo nasehlobo izimo ezingazinzile.
Akhiwe ngamaconsi amanzi namakristalu eqhwa phezulu noma etafuleni. Ngaphakathi aqukethe namaconsi emvula amakhulu, amakhekheba eqhwa, iqhwa eliwugwadule, isichotho futhi ezimweni zokungazinzi ngokweqile isichotho yobukhulu obukhulu.
Cishe bahlala bekhiqiza ukuhlushwa, okungukuthi, imvula enjengezihlambi, imvula noma isichotho, imvamisa, yize kuneqhwa ebusika, kuhambisana nemimoya enamandla nokukhipha ugesi okwenzeka phakathi kwamafu noma phakathi kwefu nomhlabathi (umbani).
AmaCumulonimbus amakhosi amafu, athwetshulwe kakhulu futhi okumangalisa kakhulu. Bayazibophezela ekubonisweni kunoma yisiphi isimo futhi kuyathakazelisa ukukwazi ukubathwebula ngokulandelana kwesiphepho. Akufanele kudidaniswe I-Cumulus congestus njengoba iCumulonimbus yinde, yethula isakhiwo semicu eziqongweni.
Zethula izinhlobo ezimbili (iCalvus neCapillatus) futhi azilethi izinhlobo.
