Ukwakheka kwamafu amaningi kubangelwa ukunyuka okuphezulu komoya oswakeme owanda ngenxa yokwehla kwengcindezi nge kokuwa ngakho-ke ukuphola kwe-adiabatic. Ngemuva kwalokho ingxenye yomhwamuko wamanzi iyabumbana yakhe ifu.
Phambilini besichaza izici zezinhlobo ezahlukahlukene zamafu nokuthi ubujamo bawo bungumphumela wezinqubo zokukhuphuka komoya okuyizinto eziwakhayo. Izinhlobo ezahlukahlukene ze ukunyakaza okuqondile okungaholela ekwakhekeni kwamafu kubhalwe ngezansi:
- Ukuhlukumezeka kwemishini (noma ukuqubuka kwesiphithiphithi)
- I-Convection (noma isiphithiphithi esishisayo)
- Ukukhuphuka kwe-Orographic
- Umqansa omude nohamba kancane
La ukuxokozela kwemishini noma ngokushayisana kuvela lapho umoya ogeleza ebangeni eliseduze lomhlaba ususwa ngamandla okulwa ochungechungeni lwe-eddies. Lesi siphithiphithi sithandwa ukuba khona kwezithiyo (izihlahla, izakhiwo, amagquma, njll.).
Imisinga ye ukuhlangana Zikhula lapho umoya ushiswa endaweni eseduze. I- ukuhlangana noma i-turbulence eshisayo ihlangana ne-mechanical noma i-frictional turbulence ukudala ukuxuba kwezingqimba ezingezansi zomkhathi.
Ku ukwenyuka kwe-orographic okwenzekayo ukuthi lapho umoya ufinyelela ochungechungeni lwezintaba noma amagquma uphoqeleka ukuba uvuke kokubili ezingxenyeni ezingezansi nasendaweni ephakeme. Ukunyukela phezulu kuthinta ungqimba olujulile lomkhathi futhi ukwabiwa okuqondile mpo kokushisa okukuwo kuyashintshwa. Umoya ophoqelelwe ukuba uvuke upholile ngokwandiswa kwe-adiabatic futhi amafu angakha.
El ukwenyuka kwesandiso esikhulu esivundlileImvamisa ekuqaleni kubangelwa ukwehluka kwe-troposphere ephezulu. Ukugeleza okuhlukile ezindaweni eziphakeme kubangela ukwehla kwengcindezi ezingxenyeni ezingezansi eduze kobuso bomhlaba, kwakheke ukucindezeleka. Ukuhlangana bese kwenzeka eduze kogu lolwandle futhi ukukhuphuka okuningiliziwe nokubanzi okuvundlile kwenzeka ngaphezulu kobukhulu obukhulu be-troposphere bese kuthi, uma nje kukhona umswakama owanele, kwenzeka ukukhula okukhulu kwamafu.

Imininingwane engaphezulu - I-Cumulonimbus, Ukuphakama, ukuphakama, ubukhulu obuqondile namazinga wefu, Ukujiya, ukubanda kanye ne-sublimation
