Kuze kube manje sesibhekane namafu ubukhulu bawo obukhuliswe kakhulu ku- isandiso enezingqimba kepha kulokhu sikhuluma nge amafu athuthukayo aqondile futhi sizoqala ngolunye lwezinhlobo ezimbili ezingabekwa kanjena, sikhuluma ngeCumulus.
I-Cumulus ngamafu ahlukanisiwe, ngokuvamile aminyene futhi anemigqa echazwe kahle, ekhula ibheke phezulu ngendlela ye amabhampu, izindlu, noma imibhoshongo, futhi izingqimba ze-convex zazo zivame ukufana nokholifulawa. Izingxenye ezikhanyiswe ilanga zalawa mafu zimhlophe qwa; isisekelo saso simnyama futhi siqondile. Kwesinye isikhathi zibonakala zidwengulwe umoya.
Akhiwa ikakhulukazi ngamaconsi amanzi noma amakristalu eqhwa kulezo zingxenye zefu okuthi, ngenxa yokuphakama kwazo, kumazinga okushisa angaphansi kuka-0º C. Zingaqukatha amaconsi amanzi aqoshwe phezulu. Ziyakhula lapho zenzeka imisinga ehambayo kubangelwa ukushisa okungalingani komoya ebusweni bomhlaba. Lapho ukhuphuka, lo moya uyajiya uye efwini futhi uzokhula kuye ngezinga lokungazinzi komoya okukhona ngaleso sikhathi.
Isimo sezulu esikahle i-Cumulus ikhula ehlobo kusuka emini kuze kube sekushoneni kwelanga, lapho ichitheka. Uma kunesilinganiso esithile sokungazinzi bangadlulela phambili I-Cumulus congestus kuthi yena abe yiCumulonimbus, ngezihlambi ezinkulu neziphepho. Akufanele zididaniswe nazo iStratocumulus, noma ngeCumulonimbus.
Ziqhathanisa ngokuphelele nombala oluhlaza okwesibhakabhaka ngenxa yobuningi bazo obenza zibonakale zimhlophe futhi zikhanya. Ngesizathu esifanayo izisekelo zizovela zimnyama noma zimnyama. Kufanele usebenzise Isihlungi se-polarizing ngokungafani okuphelele phakathi kwefu nesibhakabhaka kanye nokulungisa ukugxila kuma-bumps.
Zihlukile izinhlobo ezine (Cumulus humilis, Cumulus mediocris, Cumulus congestus and Cumulus fractus) kanye nezinhlobonhlobo (Cumulus radiatus).
