I-United States National Hurricane Center (NHC) ikhiphe ukuguqulwa ku ISaffir-Simpson Hurricane Scale, elinganisa ubukhulu bemimoya yezishingishane ezishisayo lapho zifinyelela esigabeni sesiphepho. Lesi sikali sisuka ku-1 (amandla aphansi emimoya) kuye ku-5 (amandla aphakeme kakhulu emimoya ngakhoke angaba nomonakalo ongakanani).
Lokhu kuguqulwa kwenziwa ukuze kwenziwe ukuguqulwa kwamayunithi wokulinganisa asetshenziselwe ukulinganisa isivinini somoya kalula. Njengoba kusetshenziswa amakhilomitha ngehora (Km / h), amafindo (kt) namamayela ngehora (mph), isilinganiso esedlule besidukisa lapho kuzungezwa amanani we isivinini somoya emingceleni ephakathi kwezigaba ezahlukahlukene.
Njengoba kuboniswe ngu I-National Hurricane Centre Isikali esisha sizosebenza kusukela ngoMeyi 15, 2012, olwandle iPacific Ocean, iNorth-Eastern Pacific Ocean kanye neGulf of California, ngenkathi sizosetshenziswa kusukela ngoJuni 1, 2012 e-Atlantic Ocean, eGulf of Mexico nase Ulwandle lweCaribbean.
Ngokuhlukaniswa okusha, izigaba 1 no-2 azishintshiwe. Isigaba 3 manje sizofinyelelwa ngemimoya eqinile ka-96 kuya ku-112 kt (noma u-111 kuya ku-129 mph noma u-178 kuya ku-208 km / h). Isigaba 4 sizorekhodwa uma amandla aphakathi kuka-113 kuya ku-136 kt (130 kuya ku-156 mph noma u-209 kuye ku-251 km / h). Futhi ekugcineni, isigaba 5 sizolinganiswa nemimoya phakathi kuka-137 kt noma ngaphezulu (157 mph noma ngaphezulu noma 252 km / h noma ngaphezulu).
INational Hurricane Centre iveze esitatimendeni esishiwo ngenhla ukuthi iziphepho ezedlule emlandweni ngeke zihlupheke akukho ukuguqulwa Mayelana nokuqina kwemimoya abenze ukuba kwehle umhlaba, okungukuthi, lesi simo esisha sizosebenza ezinkathini ezintsha ezilandelayo zeziphepho.
