Ukuthuthukiswa kwe- amafu kuhamba kancane, ngokusobala, lapho inqubo ebaqalayo iyeka ukwenzeka. Kepha ezinye izinto zingangenelela kubangele ukunyamalala amaconsi amanzi noma amakristalu eqhwa avela emafini njengokushisa komoya, imvula nokuxubana nomoya ozungezile owomile.
Ifu lingafudunyezwa ngokumunca imisebe yelanga noma yasemhlabeni, kepha zombili lezi zimo zibuthakathaka uma kuqhathaniswa ne- Ukushisa kwe-adiabatic.
Yilokhu okungenzeka uma umoya lapho ifu litholakala khona uxhaswa. Njengoba izinga lokushisa lomoya lenyuka, umswakama ohlobene nawo uyehla futhi umoya ungagcwala; bese kuthi izinhlayiya zamafu zihwamuke zibe umhwamuko ongabonakali wamanzi.
La ilanga kuvame ukudala ukuncibilika kwamafu okudalwe yisiyaluyalu. Uma imisebe yelanga eyanele ingena emhlabathini, ifudumeze umoya eduze komhlaba, izinga lokuncipha kwenhlanganisela liyakhuphuka futhi, ngakho-ke, isisekelo seStratus noma iStratocumulus siyakhuphuka futhi. Ngemuva kwalokho, ubukhulu befu obukhawulelwe ukuguqulwa kwesiyaluyalu buyancipha futhi ifu ekugcineni linyamalale ngokuphelele.
I-Los I-cumulus enhle yesimo sezulu, ezakhiwa emazweni angaphansi kwethonya lokuziqothula, ziyinto yesikhashana. Imvamisa zivela ekuseni, zifinyelela ukukhula kwazo okuphezulu phakathi nentambama futhi zinyamalale masisha lapho inhlabathi iphola futhi ekupheleni kosuku.
Umoya ozungeze ifu uvame ukungasuthiswa. Ukuxubaniswa kwefu nalo moya kungakhipha umswakama ohlobene ngaphansi kuka-100% futhi kukhiqize okunye ukuhwamuka efwini, eligugulayo futhi elingashabalala.
