Ngakhale tsinde lonyowa posungira kapena 'dzimbiri loyera' silisokoneza chitetezo cha zokutira zamagalasi, ndi vuto lokongola lomwe ndi losavuta kupewa.

Kuthimbirira kosungirako konyowa kumachitika pamene zida zamalata zatsopano zimakumana ndi chinyezi monga mvula, mame kapena condensation (chinyezi chachikulu), ndikukhalabe pamalo opanda mpweya wochepa pamtunda.Izi zitha kukhudza momwe patina yoteteza imapangidwira.

Nthawi zambiri, zinki imayamba ndi mpweya kupanga zinc oxide, kenako ndi chinyezi kupanga zinc hydroxide.Ndi mpweya wabwino, zinc hydroxide imasandulika kukhala zinc carbonate kuti ipereke chitetezo chotchinga ku zinki, motero kumachepetsa kuwononga kwake.Komabe, ngati nthaka ilibe mpweya wotuluka mwaulere ndipo imakhalabe pachinyezi, zinc hydroxide imapitilira kukula m'malo mwake ndikupanga banga lonyowa.

Dzimbiri loyera limatha kuchitika pakadutsa milungu ingapo kapena usiku ngati zinthu zili bwino.M'madera ovuta kwambiri a m'mphepete mwa nyanja, madontho osungiramo madzi amathanso kuchitika kuchokera kumalo amchere omwe amapangidwa ndi mpweya omwe amamwa chinyezi usiku.

Zitsulo zina zamagalasi zimatha kupanga mtundu wa banga lonyowa posungira lomwe limadziwika kuti 'mawanga akuda', omwe amawoneka ngati madontho akuda kapena opanda dzimbiri loyera mozungulira.Mtundu woterewu wamtundu wosungiramo madzi umakhala wofala kwambiri pazitsulo zoyezera mopepuka monga mapepala, ma purlins ndi zigawo za dzenje zoonda.Ndizovuta kwambiri kuyeretsa kuposa mitundu ya dzimbiri yoyera, ndipo nthawi zina madontho amatha kuwoneka akatsuka.
