Gululi linapeza pamaso pa yogwira mesoscale munda mmene kanyamaka. Amakhala ndi lalikulu mphete anticyclone ndi malo ofunda ndi zizindikiro mumlengalenga ya moto ozizira.

Mwachidule, tikhoza kupereka yankho kwa aliyense amene ali ndi chidwi mu funso: Benguela Current - ofunda kapena ozizira? Ndithudi ndi ozizira, pamene kukhala ndi makhalidwe amphamvu kwambiri, kale tatchulazi. otaya wakhala kudziwika kwa nthawi yaitali, koma kuphunzira zambiri za hydrologists ake, asayansi anayamba ndi posachedwapa. Mu nthawi yochepa ife anatha kupeza chiyambi chake ndi kupereka malongosoledwe yaing'ono. Ndipo ichi ndi choona kuti amphamvu kwambiri, ndipo ili mukuimira munthu kuopseza navigation.
