Los neempukane Ziziganeko zemeteorological ezithi zibonwe sisathelayithi, zibonwe njengeenkqubo ezilungelelaniswe kakuhle, kwaye zinobuhle bodwa. Nangona kunjalo, zihlala zibangela ukonakala kwezinto ezibonakalayo kwaye zinokubulala abantu abangamakhulu, njengoko kwenziwe yiNkanyamba uMateyu eHaiti.
Kodwa ngubani ogqiba igama lenkanyamba? KUNYE, Kutheni le nto benamagama abo?
Uluhlu lwamagama ezitshingitshane zaseTropiki ezenzeka kuLwandlekazi lweAtlantic yadalwa ngo-1953 liZiko leNkanyamba leLizwe laseMelika (NHC). Okwangoku, olu luhlu lusetyenziswa njengomgangatho woluhlu lweminye imimandla yehlabathi, kwaye luhlaziywa yiWorld Meteorological Organisation (WMO), eyiarhente yeZizwe eziManyeneyo ezinze eGeneva (Switzerland).
Amagama enkanyamba ahlelwe ngokulandelelana, ngaphandle koonobumba u-Q, U, X, Y, no-Z, amagama abesilisa nabasetyhini bayatshintsha. Amagama ahlukile kwingingqi nganye, ukuze izilumkiso zinikwe ngcono kwaye akukho siphithiphithi.
Nangona kusenokubonakala ngenye indlela, amagama asetyenzisiweyo, hayi ngesiNgesi kuphela, kodwa nakwiSpanish nesiFrentshi. Ukongeza, ziphinda zisetyenziswe kwakhona rhoqo emva kweminyaka emithandathu, kodwa zikhona ezinye eziyekayo ukusetyenziswa ukuba inkanyamba ekuthethwa ngayo ibikhe yanzima, njengoko kwenzekayo kuKatrina, owashiya ama-2000 2005 ebhubhile eNew Orleans (USA) ngo-XNUMX, umzekelo.
Njengomdla, kufuneka kuthiwe izazi zemozulu zazisebenzisa uninzi lwamagama ababhinqileyo ngexesha leMfazwe yesibini (II) yeHlabathi: amagama oomama babo, abafazi babo okanye abathandanayo, ucacisile uKoji Kuroiwa, intloko yenkqubo yeWMO yetropiki. Ukususela ngo-1970, amagama angamadoda nawo afakwa ukunqanda ukungalingani ngokwesini.
Nangona kunjalo, iinkanyamba zabasetyhini zibulala abantu abaninzi kunalezo zinamagama angamadoda, ngokwe-a kufunda Ukusuka kwiDyunivesithi yaseIllinois (iUSA). Isizathu kukuba eyokuqala ayiqhelekanga ithathwa ngokungathí sina, kungoko ke kuthathwa amanyathelo okulungiselela ukujongana nazo. Ngesi sizathu, iZiko leNkanyamba leLizwe ligxininise ukuba, nokuba leliphi igama lenkanyamba, Ujoliso kufuneka lube kwisoyikiso esenziwa ngumntu ngamnye.
