Siyazi ukuba iinkanyamba ezikwiitropiki zinokuqina ngokukhawuleza. Uninzi lwazo lunezigaba ezi-5 okanye ezifanayo. Xa inkanyamba efikelela kwezi ndidi yaziwa ngegama lenkanyamba okanye iinkanyamba. Uninzi lwazo lubonisa iliso elincinci, elichazwe kakuhle elibonakalayo, ngakumbi kwimifanekiso yesathelayithi kunye nereda. Zihlala ziimpawu eziphawula amandla enkanyamba yetropiki. Namhlanje siza kuthetha Inkanyamba uHagibis, kuba wayekhetheke kakhulu ngamehlo kunye noqeqesho.
Kule nqaku siza kukuxelela yonke into ofuna ukuyifumana malunga neTyphoon Hagibis, iimpawu zayo kunye nokwakheka kwayo.
Iimpawu eziphambili
Ukuba asibhekiseli kwiinkanyamba kunye neenkanyamba, ezi zinto zibunjwe ziinxalenye ezi-3: iliso, udonga lwamehlo kunye neziqwengana zemvula. Xa sithetha ngamehlo enkanyamba, sithetha ngeziko lenkanyamba apho yonke le nkqubo ijikelezayo. Kwi-avareji, iliso lenkanyamba lihlala malunga neekhilomitha ezingama-30-70 ubukhulu. Ngamanye amaxesha inokufikelela kububanzi obukhulu, nangona ingeyoyona ixhaphakileyo. Zizo kuphela ezo nkanyamba zikwenzayo. Ngamanye amaxesha, sinokuba neliso elincitshiswe laya kwiidayimitha ezincinci kwaye zihambelana ngakumbi. Umzekelo, iTyphoon Carmen kufuneka ibe neliso leekhilomitha ezingama-370, ibe lelona likhulu kwirekhodi, ngelixa iNkanyamba uWilma ineliso elinye leekhilomitha ezingama-3.7.
Ezinye iinkanyamba kunye neenkanyamba zivelisa oko kubizwa ngokuba liliso lokurenta okanye iliso lentloko eliqeshisayo. Kwenzeka xa iliso lenkanyamba lincinci kakhulu kunesiqhelo. Yile nto yenzekileyo kwiNkanyamba uHagibis ngo-2019. Iliso elincinci lenza ukuba inkanyamba ibe namandla ngakumbi njengoko inkanyamba ejikeleze iliso ijikeleza ngokukhawuleza okukhulu. Izitshingitshane ezinamandla zetropiki ezinamehlo aqeshisayo zihlala zenza ukuguquguquka okunamandla kubunzulu obuphezulu ngenxa yemimoya edibeneyo.
Phakathi kweempawu zeNkanyamba uHagibis Sifumana ubungakanani bayo be-mesoscale. Oku kuthetha ukuba yinkanyamba ekunzima ukuyichaza ngokubhekisele kumgaqo kunye nokuqina kwemimoya. Olunye uphawu lweNkanyamba uHagibis, ukongeza kwiliso lenkanyamba, ludonga lwamehlo kunye neebhendi zemvula ezibonisa onke amacandelo abalulekileyo kwisaqhwithi. Okokugqibela, izibophelelo zemvula ngamafu enza uqhwithela kwaye ajikeleza udonga lweliso. Zihlala zifikelela kumakhulu eekhilomitha ubude kwaye zixhomekeke kakhulu kubungakanani benkanyamba xa iyonke. Iibhendi zijikeleza ngokungqinelana newotshi rhoqo xa sikwi-hemisphere esemantla kwaye zihlala ziqulatha imimoya ngamandla amakhulu.
Ukuqiniswa okukhulu kweNkanyamba uHagibis
Elinye lawona matyala akhethekileyo kwimbali ukusukela oko kwabakho iinkanyamba kunye nezaqhwithi kubhalwe iTyphoon Hagibis. Yinkanyamba enkulu eyadlula emantla eeMariana Islands ebekwe kuLwandlekazi lwePasifiki ngo-Okthobha 7, 2019. Yadlula kwezi ziqithi njenge udidi lwenkqantosi yetropiki ekhatshwa yimimoya enamandla kakhulu ye-5 yeekhilomitha ngeyure.
Eyona nto yayibalasele ngale nkanyamba yayikukuqina ngokukhawuleza. Kwaye kukuba inqanaba lokuqiniswa okuye kwaphunyezwa ziinkanyamba ezimbalwa. Kwenzekile kwiiyure nje ezingama-24 ukuba kubekho umoya oyi-96 km / h ukuze ube nemimoya engama-260 km / h. Ukwanda kwesi santya kwimimoya ephezulu egcinwe luhlobo olunqabileyo nolukhawulezayo lokuqina.
Ukuza kuthi ga ngoku, iCandelo le-NOAA loPhando lweNkanyamba ludwelisa kuphela inkanyamba enye kwiPacific Northwest eyenze njalo: Super Typhoon Forrest yowe-1983. Namhlanje, isathathwa njengesona saqhwithi sinamandla ehlabathini. Eyona nto igqame kakhulu ngolu bukhulu bukhulu kodwa iliso elincinci elijikeleza embindini kwaye lijikeleze iliso elikhulu ngokungathi libhajwe ngaphakathi. Njengoko ixesha lihamba, Ubukhulu beliso lesaqhwithi lilinganise i-5 yeemayile zemayile, ngelixa iliso lesibini layibamba.
Iliso lenkanyamba liliziko lenkanyamba elinokuthi umndilili ungabi mkhulu kakhulu, kwaye libizwa ngokuba liliso lentloko yentloko. Kwiintsuku emva kokudalwa kwayo, yadibana nesiqithi esingenabemi saseAnatahan yaza yemka eMicronesia. Yabuthathaka njengoko yayihamba isiya emantla, kwaye malunga neveki kamva yajika yaba sisiqhwithi sodidi 1-2 ukufika kwayo eJapan. Igama elithi Hagibis lithetha isantya kwiTagalog, yiyo loo nto igama laso.
INkanyamba enkulu uHagibis
Yathathelwa ingqalelo njengesona siganeko sakha sasibi kwiplanethi kuba kwisithuba seeyure ezimbalwa ukusuka ekubeni sisiqhwithi esilula sethropikhi ukuya kwinqanaba lenkanyamba 5. Yeyona nguqulelo ikhawulezayo ngalo lonke ixesha, kwaye yenye yezona zinamandla ngenxa yobunzulu bayo . Ngokubala kwintloko yerenti yenze inkanyamba eyingozi ngokwenene.
Ukwenziwa kwayo, njengezinye iinkanyamba, zenzeka embindini wolwandle. Siyazi ukuba ngenxa yokwehla koxinzelelo, umoya uthambekele ekugcwaliseni isikhewu esishiyekileyo ngokuhla koxinzelelo. Nje ukuba inkanyamba ingene elwandle kwaye ifike kwilizwekazi, ayisenayo indlela yokuzondla nangaphezulu, yiyo ke loo nto iphelelwa ngamandla xa ingena. I-Forrest enkulu ye-1983 ye-Forrest, kwaye nangona yayinesantya esifanayo sokwakheka, yayingenamandla kangako ngenxa yokungabi naliso linye.
Olu tshintsho lunento eninzi yokwenza neempawu zalo ezingaqhelekanga. Imifanekiso yesethelayithi eyafunyanwa yabonisa ukuba ineliso elincinane kakhulu ngaphakathi kwelinye elikhulu. Zombini zadityaniswa zivelisa iliso elikhulu kwaye zonyusa amandla azo. Njengomgaqo jikelele Zonke iinkanyamba zineliso elinobubanzi obuxhomekeke kumandla onawo. Ukuba incinci inobungozi.
Ndiyathemba ukuba olu lwazi ungafunda ngakumbi malunga neTyphoon Hagibis kunye neempawu zayo.
