Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Pane zvinhu zvakasiyana-siyana zvinowanzoshandiswa kuyera kukura kwedutu. Mametric akajairika anosanganisira nharaunda yemhepo yakanyanya, nharaunda yemhepo yemakumi matatu nemana (kureva simba remhepo), nharaunda yekunze yakavharwa isobar (ROCI), uye nharaunda yemhepo inonyangarika. Imwe metric ndeye radius iyo iyo cyclone's relative vorticity field inoderera kusvika 1×10−5 s−1.Panyika, madutu emuchadenga anotambanudza huwandu hukuru, kubva pa100<unk>2,000 makiromita (62<unk>1,243 mi) sekuyerwa ne radius yemhepo inonyangarika. Iwo akakura zvikurusa paavhareji munharaunda yokuchamhembe kwakadziva kumadokero kwePacific Ocean uye maduku zvikurusa munharaunda yokuchamhembe kwakadziva kumabvazuva kwePacific Ocean. Kana nharaunda yeisobar yakavharwa iri kunze isingasviki madhigirii maviri (222 km (138 mi)), ipapo dutu "duku zvikuru" kana kuti "duku". Nharaunda ye 3<unk>6 degree latitude (333<unk>670 km (207<unk>416 mi)) inoonekwa se "avhareji". Dutu remhepo rinopisa "rakakura kwazvo" rine nharaunda inopfuura madhigirii masere (888 km (552 mi)). Kucherechedza kunoratidza kuti kukura kunongobatana zvishoma chete nezvakasiyana-siyana zvakadai sokusimba kwedutu (kureva kumhanya kwemhepo kwakanyanya), nharaunda yemhepo yakanyanya, kureba, uye kusimba kwakanyanya. Kukura kunoita basa rinokosha mukugadzirisa kukanganisa kunokonzerwa nedutu. Zvimwe zvinhu zvose pazvinenge zvakaenzana, dutu guru rinokanganisa nzvimbo yakakura kwenguva yakareba. Mukuwedzera, nzvimbo yakakura yemhepo iri pedyo nepasi inogona kuunza dutu rakakwirira nekuda kwekubatanidzwa kwemhepo yakareba, nguva yakareba, uye kuwedzerwa kwemafungu.
