Yintoni iTyphoon?

Inkanyamba ibonwa yisathelayithi

Xa kukho inkanyamba ebangela umonakalo omkhulu kwenye indawo kwintshona yePacific, igama liphindaphindwa kakhulu inkanyamba, ekhokelela ekudidekeni xa enyanisweni ingafanelekanga. Olu lwakhiwo luneempawu ezifanayo neziphepho ezenza iAtlantic. Ngapha koko, banomahluko omnye kuphela: indawo yabo yoqeqesho.

Oku kuthetha ukuba zizimo zemozulu ezinako ukusimangalisa kwaye zisibangele sibe noloyiko lwenene, kuxhomekeke kubunzulu bazo kunye nokuba zikuphi. Kodwa, Bazintoni?

Yenzeka njani inkanyamba?

Ukuqulunqwa kwenkanyamba okanye inkanyamba

Iinkanyamba okanye iinkqwithela zitshingitshane ezitshisa iAtlantic kunye nePasifiki, kodwa kuphela xa ulwandle lufudumele kakhulu, lunobushushu obungama-22 ngokukaCelsius. Umoya wolwandle ofudumeleyo nolufumileyo uyenyuka ubangela indawo enomoya ophantsi kufutshane nolwandle. Kwenzekani? Umoya, uhamba ngendlela eyahlukileyo, wenza ukuba isaqhwithi siqale ukujika.

Umoya uphakama ngokukhawuleza kwaye ngokukhawuleza uzalisa indawo ephantsi yoxinzelelo, wondliwe ngumoya ofudumeleyo ovela kulwandle. Kwangaxeshanye, ifunxa umoya obandayo kunye owomileyo ovela phezulu, oya ngqo ezantsi. Kodwa oku akupheleli apha: ngelixa uhamba elwandle, isantya somoya siyaqhubeka ukwanda njengoko iliso lesaqhwithi lithatha umoya oshushu. Embindini wale meko le meko izolile noko, kungoko uxinzelelo lomoya luphantsi kakhulu.

Udidi lwenkanyamba

Yintoni iSaffir-Simpson Scale?

Isantya esifikelelwe yimimoya yezi zinto zihlelwa ngokweSaffir-Simpson isikali senkanyamba. Eli nqanaba laphuhliswa yinjineli yaseburhulumenteni uHerbert Saffir kunye nomlawuli weZiko leNkanyamba leLizwe laseMelika, uBob Simpson ngo-1969.

Imvelaphi yaveliswa nguSaffir, owaqonda ukuba akukho sikali sichazayo sokuchaphazela iziphumo zenkanyamba. Ke, waqulunqa enezilinganisi ezintlanu ngokusekwe kwisantya somoya. Emva kwexesha, uSimpson uza kongeza iimpembelelo zamaza nezikhukula.

Ukongeza, njengoko inkanyamba yetropiki ifumana amandla, idlula kumanqanaba amabini okuqala, aludandatheko lwetrophiki kunye nesitshingitshane setropiki. Makhe sibone ukuba zahluke njani:

  • Uxinzelelo lwetrophiki: yinkqubo elungelelanisiweyo yamafu kunye nesaqhwithi sombane esine-circulation echazwe kakuhle. Uxinzelelo oluphakathi ngu> 980mbar, kwaye isantya somoya sisuka kwi-0 iye kwi-62km / h. Ingabangela izikhukula ezinkulu.
  • Isitshingitshane seTropical: yinkqubo ehleliweyo yeendudumo ezinamandla kakhulu ezinesasaza elijikeleziweyo. Inobume be-cyclonic, kwaye uxinzelelo oluphambili ngu> 980mbar. Umoya unokuvuthuza phakathi kwe-63 kunye ne-117km / h, ke bayakwazi ukuvelisa iinkanyamba.

Ulwahlulo lwenkanyamba

Iliso lesiphango

Ukuba inkanyamba iya isomelela ngakumbi, iya kuqala ukubizwa ngokuba yinkanyamba okanye inkanyamba.

  • Icandelo loku-1: uxinzelelo oluphakathi yi-980-994mbar, isantya somoya yi-74 ukuya kwi-95km / h, kwaye amaza aphakathi kwe-1,2 kunye ne-1,5m.
    Ibangela izikhukula zonxweme, kunye nomonakalo wemithi kunye namatyholo, ngakumbi lawo atyalwe ixesha elincinci.
  • Icandelo loku-2: uxinzelelo oluphakathi yi-965-979mbar, isantya somoya yi-154 ukuya kwi-177km / h, kwaye kukho amaza aphakathi kwe-1,8 kunye ne-2,4m.
    Kubangela ukonakala kophahla, iingcango, iifestile, kunye nohlaza, kunye namakhaya ahambayo.
  • Icandelo loku-3: uxinzelelo oluphakathi ngu-945-964mbar, isantya somoya yi-178-209km / h kwaye kukho amaza e-2,7 ukuya kwi-3,7 yeemitha.
    Ibangela ukonakala kunxweme, apho itshabalalisa izakhiwo ezincinci. Kusenokubakho izikhukula ngaphakathi elizweni.
  • Udidi 4: uxinzelelo oluphakathi yi-920-944mbar, isantya somoya yi-210 ukuya kwi-249km / h, kwaye amaza aphakathi kwe-4 kunye ne-5,5m.
    Idala umonakalo omkhulu kwizakhiwo ezincinci, ukhukuliseko lolwandle kunye nezikhukula zangaphakathi.
  • Icandelo loku-5: uxinzelelo oluphakathi ngu- <920, isantya somoya singaphezulu kwama-250km / h, kwaye kukho amaza angaphezulu kwe-5,5m.
    Yenza umonakalo omkhulu emanxwemeni: izikhukula, ukutshabalalisa uphahla, ukuwa kwemithi, ukukhukuliseka komhlaba. Ukukhutshwa kwabahlali kunokuba yimfuneko.

Ngaba ziluncedo?

Ukuthetha malunga neenkanyamba kushushu, okanye ngokufuthi kuhlala kuthethwa ngeziganeko ezibangela umonakalo omkhulu. Kodwa inyani kukuba ngaphandle kwabo, kwezinye iindawo zehlabathi banokuba neengxaki ezininzi.

Ke, izibonelelo zezi:

  • Batsala iimvula kunye nemimoya, Ukunceda ukuba iindawo ezomileyo azome kangako.
  • Bavuselela amahlathi. Izifo ezigulayo kunye / okanye ezibuthathaka azinakumelana nokudlula kwenkanyamba, ngoko ke xa zikhutshwa zishiya indawo yokuba imbewu ihlume ikhule.
  • Gcwalisa amadama uze uvuselele kwakhona imithombo yamanzi ukuze amafama axhamle.
  • Banceda ukunciphisa amaqondo obushushu kwiitropiki enokuphakama ngaphezulu.

Inkanyamba evela emajukujukwini

Izaqhwithi yenye yezona zinto zimangalisayo zemozulu, awucingi? Ndiyathemba ukuba eli nqaku beliluncedo kuwe ukuze wazi iimpawu zalo kunye nendlela ezihlelwa ngayo.
