Ukusakazwa kwe-Oceanic kungaba injini enkulu ye- asymmetry emibusweni ye izimvula ezishisayo Lina kakhulu enyakatho kunaseningizimu ye-equator, kepha inkabazwe on ivezwe kakhulu emisebeni yelanga, ngakho-ke ngezinga eliphakeme lokukhuphuka kwe- umswakama.
Lokhu kubhekwa bekuhlale kuyindlela ye- imfihlakalo, kepha namuhla iqembu labacwaningi baseMelika likhombisa ukuthi kungabangelwa yi ukusakaza i-meridian olwandle.
Ngaphansi kwe- ezishisayo, lina kakhulu enyakatho kunaseningizimu. Imvula enkabazwe ilungiswa ngendawo ye- ukuhlangana ezifudumele. Iqembu lomkhathi lamakhilomitha angamakhulu amaningana, akhiwa ukuhlangana kwenqwaba ye umoya kushisa futhi kumanzi, kududulwa yimimoya yezohwebo.
Leli bhande lefu lakha i- rama ukhuphuka yamaseli weHadley, asabalalisa ngakolunye uhlangothi kolunye i-ecuador insalela yamandla anqwabelene. Noma kunjalo, le ndawo ye ukuhlangana ezishisayo Ayikho ngqo enkabazwe, kepha ngo-5º N. Isikhundla saso sibangela asymmetry ezindaweni zemvula okwakungaziwa isikhathi eside isizathu sazo.
Ososayensi kudala bathi lo mehluko ku imvula ezishisayo ku-geometry yezilwandle. I- asymmetry imvula izobe ihlobene ne-asymmetry ye- lokushisa olwandle, nalo luhlobene ne-asymmetry ye- emuva Izwekazi.
Empeleni, kubonakala sengathi ukusakaza i-thermohaline kuyindlela esemqoka ebangela le asymmetry.
