Kune mhando dzakasiyana dzema metric anowanzo shandiswa kuyera saizi yedutu. Iwo akajairika metric anosanganisira radius yemhepo yakanyanya, iyo radius yemhepo ye34-knot (kureva dutu remhepo), iyo radius yekunze yakavharwa isobar (ROCI), uye radius yemhepo inonyangarika. Imwe metric ndeye radius iyo iyo cyclone's yakaenzana vorticity munda inodzikira kusvika 1 × 10−5 s−1.Panyika, madutu emvura anogara munzvimbo yakakura, kubva pa1002,000 km (62<unk>1,243 mi) sekuyerwa ne radius yemhepo inonyangarika. Iwo akakura paavhareji mudunhu rekuchamhembe kwakadziva kumadokero kwePacific Ocean uye madiki kuchamhembe kwakadziva kumabvazuva kwePacific Ocean. Kana radius yemhepo yakavharwa iri pasi pemadhigirii maviri emhepo (kureva 34-knot mhepo (kureva dutu remhepo), iyo radius yekunze yakavharwa yakavharwa isobar (ROCI), uye radius yemhepo inonyangarika.
