Nyorai kupfuurira kweiyi ndima - Kukwira mumhepo kunokonzerwa nemhepo yakaderera-yakaderera ichipindana nepamusoro pemvura kunodzikisa makore uye zvichida kunaya kwemvura. Denga rine makore romunzvimbo ine mhepo yakaderera rinoderedza kuchinja-chinja kwetembiricha mukati mezuva. Sezvo makore achiratidza chiedza chezuva, mwaranzi yezuva inouya ishoma, izvo zvinoita kuti kutonhora kuve kwakaderera mukati mezuva. Usiku, simba rinopinza remakore pamwaranzi yemasaisai marefu inobuda, yakadai sesimba rinopisa rinobva pamusoro, rinobvumira tembiricha yakaderera inopisa mukati mezuva mumwaka yose. Kana nzvimbo ine kumanikidzwa kwakaderera yakasimba, mhepo dzinenge dziri pedyo nayo dzinenge dzakasimbawo. Munyika yose, masisitimu edzvinyiriro yakaderera anowanzowanwa pamusoro peTibetan Plateau uye mumakomo eRocky Mountains. MuEurope - zvikurukuru muUnited Kingdom neNetherlands - mamiriro okunze anodzokororwa anodzvinyirira anowanzozivikanwa semadzerere.
