Namhlanje siza kuthetha ngohlobo lwe impepho yasentabeni exhaphake kakhulu kwiindawo ezininzi kwilizwe lethu ngenxa yendalo esezintabeni.
Ngexesha lasebusuku obucacileyo umoya uhamba uhamba kumathambeka eenduli okanye weentaba uze wehle uye ezintlanjeni apho uqhubeka usiya khona emathafeni. Olu hlobo lokuhamba lubizwa umoya katabatic (livela kwisiGrike kwaye lithetha "phantsi"). Kubeka ebusuku xa umhlaba upholile yimitha.
Umoya odibene naloo mhlaba ubandayo uyaphola ze emva koko ubemandla ngakumbi kunomoya ojikelezileyo; ke amandla omxhuzulane anyanzela ukuba wehle ithambeka lendawo kwaye ukuhamba komoya okumiselweyo kuyamiselwa. Umoya uhlala unxibelelana nomhlaba obandayo kwaye uyaqhubeka nokuphulukana nobushushu; ke ukufudumeza akuyiyo i-adiabatic (utshintsha ubushushu kunye naphakathi) kwaye intshukumo iyaqhubeka.
Ngokubanzi, olu hlobo lomoya opholileyo lubuthathaka. Nangona kunjalo, kwezinye iimeko, xa ithambeka liqhinile kwaye ligudile, linokufikelela kumandla amakhulu. Oku kuyenzeka xa umphezulu ugqunywe likhephu okanye ngumkhenkce, into exhaphake kakhulu kwi Antarctica. Kwimeko apho iintaba zikufutshane nolwandle, umoya ococekileyo wasentabeni unokuqinisa impepho yomhlaba ebusuku ibangele imimoya enamandla kakhulu elwandle.
Okokugqibela, hlomla ukuba umoya we-catabatic yenye yeendlela eziyimfuneko kwisenzeko se Ukuguquka kobushushu, kuba umoya obandayo womxhuzulane uya kugcinwa emazantsi entlambo, iqondo lobushushu liphakame ngandlela ithile encotsheni yeentaba.
