Ukwakhiwa kwamafu amaninzi kubangelwa kukunyuka okuphezulu komoya ofumileyo owandayo ngenxa yokwehla koxinzelelo kunye ukuphakama kwaye ke ukupholisa adiabatic. Emva koko inxalenye yomphunga wamanzi iyadibana ukuze yenze ilifu.
Ngaphambili besichaza iimpawu zeentlobo ezahlukeneyo zamafu kunye nendlela ezime ngayo zisisiphumo seenkqubo zokuphakamisa umoya eziyiloyo. Iindidi ezahlukeneyo ze iintshukumo nkqo ezinokukhokelela ekwakhiweni kwamafu zidweliswe apha ngezantsi:
- Uqhushululu loomatshini (okanye isiphithiphithi esinokukhuhla)
- Ikhonkco (okanye isiphithiphithi se-thermal)
- Ukunyuka kwe-Orographic
- Ukunyuka okude kunye nokucotha
La isiphithiphithi soomatshini okanye ngokhuphiswano luqala xa ukuhamba komoya kufutshane nomphezulu womhlaba kususwe ngamandla omlo ngoxinzelelo kuthotho lweeddi. Esi siphithiphithi sithandwa bubukho bezithintelo (imithi, izakhiwo, iinduli, njl.
Izahlulo ze indibano zikhula xa umoya uvutha kufutshane nomphezulu. Inkqubo ye- indibano okanye isiphithiphithi se-thermal sidibanisa nesiphithiphithi soomatshini okanye sokukhuhlana ukubangela ukuxubana kwamanqanaba asezantsi omoya.
Kulo ukunyuka kwe-orographic Into eyenzekayo kukuba xa umoya ufikelela kuthotho lweentaba okanye iinduli kuye kunyanzeleke ukuba iphakame kokubini kwimiqolo esezantsi kunye nokuphakama. Ukunyuka okuphezulu kuchaphazela umaleko onzulu weatmosfera kunye nokusasazwa kweqondo lobushushu nkqo kulo kutshintsha. Umoya onyanzelwe ukuba uphakame upholile ngokwandiswa kwe-adiabatic kwaye amafu angenza.
El Ukunyuka kolwandiso olukhulu oluthe tyabaIhlala ichukunyiswa ekuqaleni kukwahluka kwi-troposphere ephezulu. Ukuhamba okungafaniyo kwiindawo eziphakamileyo kubangela ukwehla koxinzelelo kumanqanaba asezantsi kufutshane nomphezulu womhlaba, ukwenza uxinzelelo. Ukudibana emva koko kwenzeka kufutshane nenqanaba lolwandle kwaye ukunyuka okuthe ngcembe nokubanzi okuthe tyaba kwenzeka ngaphezulu kobukhulu be-troposphere kwaye emva koko, ukuba kukho ukufuma okwaneleyo, ukukhula kwefu okuninzi kuyenzeka.
