Mhepo inokonzerwa nokusiyana kwepuresha yemweya munzvimbo dzakasiyana pano paNyika. Mhepo inovhuvhuta ichibva kupuresha yakakwirira ichienda kupuresha yakaderera. Apo mhepo inofamba ichienda kune puresha yakaderera (sezvarehwa), gwara rainotevera rinopandana negwara repakutanga; izvi zvichikonzerwa neFosi yaCoriolis. Mhepo inovhuvhuta kuChamhembe kweMuenzanisi inopandukira kuruboshwe ichisundwa neFosi yaCoriolis. Mhepo inovhuvhuta kuMaodzanyemba kweMuenzanisi inopandukira kurudyi. Mwero wekupanduka kwemhepo kubva mugwara repakutanga unoyenderana nespidhi kuti mhepo iri muvhuvhuta munzvimbo yerumbariro rwupi. Mhepo ine spidhi yakakakura inopanduka zvakakurawo. Mhepo iri kuvhuvhuta kurumbariro rwakakwirira pedyo nemagonga (poles) inopanduka zvakanyanya kubva mugwara repakutanga. Fosi yaCoriolis inenge iri zero pamuenzanisi.
