Nakuba ukukhathazeka ngoshaka, imisebe ne-jellyfish kuyinto evamile ogwini, kunosongo oluyingozi kakhulu olucashe ogwini lomhlaba wonke: ama-rip currents. Ngokuphambene nenkolelo evamile, imisinga egelezayo ayikudonseli ngaphansi kwamagagasi, kunalokho, ikuthwala ikususe ogwini ikuyise olwandle. Ngokudabukisayo, abantu abanqotshwa ukwethuka futhi balwe ngeze ngokumelene nomsinga bangase bazithole besesimweni esibi kakhulu, futhi basengozini yokuminza.
Kulesi sihloko sizokutshela indlela yokubona futhi ubalekele ama-rip currents.
Ayini ama-rip currents?
Ama-Rip currents, aziwa ngobunjalo bawo obungabazekayo, anegalelo ekutakuleni abahlengi bezilwane ezingaphezu kuka-80% e-United States kanye no-60% wezigameko zokuhlenga ezisingathwa yi-Royal National Lifeboat Institution e-United Kingdom. Inselele ilele ekubeni khona kwayo okungabonakali.
Ama-Rip currents, akha ezikhaleni phakathi kwezinguzunga zesihlabathi, Ziyimisinga yamanzi enamandla ekuyisa kude nogu. Le misinga yenziwa lapho amagagasi esondela ogwini ngendlela eqondile futhi engakwazi ukuhlakazeka.
NgokukaSimon Boxall, uprofesa eNational Oceanography Center eNyuvesi yaseSouthampton, amanzi awagelezi nhlangothi zombili, kodwa kunalokho ayanqwabelana futhi kufanele athole indlela yokuphuma, akwenza ngokuba khona kwe-rip current.
Zakhiwa kanjani
Imisinga ye-Rip inamandla okwenzeka kunoma iyiphi inkimbi yamanzi ezwa umsebenzi wamagagasi, kuhlanganise namachibi Amakhulu. Nokho, Zivame kakhulu kulokho okuvame ukubizwa ngokuthi amabhishi "akudala"., lapho ugu lwehlela kancane kancane lubheke olwandle. Ngokusho kochwepheshe, njengoba amagagasi esondela ogwini, ayahlehla noma agobe, futhi lapho umqansa wolwandle ukhuphuka, amagagasi aya ngokuya ehambisana. Lokhu, futhi, kwandisa amathuba okwakheka kwe-rip current.
Eyaziwa ngamandla ayo, ama-rip currents angatholakala emabhishi afana ne-Boomerang Beach e-Australia, i-Panama City Beach e-Florida, ne-Lamu Island e-Kenya. Kodwa-ke, kubalulekile ukukhumbula ukuthi le misinga ingenzeka kunoma yiliphi ibhishi elinamagagasi. Ngakho ungayibona kanjani i-rip current?
Indlela yokuyikhomba
Izinkomba zokugeleza kwamanzi zingase zibonakale njengezindawo zombala wamanzi ohlukile, ukuphazamiseka kwamaphethini amagagasi, noma ukuba khona kwesiteshi esithwala igwebu noma amanzi anesihlabathi esiya olwandle oluvulekile.
NgokukaRob Brander, owaziwa nangokuthi “uDkt. Rip” kusukela ku-UNSW Beach Safety Research Group e-Sydney, e-Australia, uma ubona ukuvuleka okungaguquki okumnyama ku-surf eqhubeka nokuya olwandle, kungenzeka ukuthi i-rip current.
Ekusesheni kwakho ama-rip currents, skena ngokucophelela usebe lolwandle imizuzu embalwa, kungaba ukusuka endaweni ephakeme ohlangothini noma endaweni ephakeme, njengendunduma yesihlabathi. NgokukaBrander, ukukhomba ama-rip currents asuka ogwini kuhlala kunzima kakhulu, ngakho-ke kubalulekile ukwenza okungaphezu kokubuka nje.
Ukubona ama-rip currents kungaba umsebenzi onzima, ngisho nakulabo abanolwazi, njengoba ngokuvamile ababoni futhi benamandla okushintsha ngokushesha. UChris Cousens, onguMholi Wezokuphepha Emanzini we-RNLI eWales, ulandisa ngokuhlangenwe nakho kwakhe, ethi: “Naphezu kweminyaka engu-30 ngintweza emanzini, ngezinye izikhathi ngikuthola kunzima ukubona ngokushesha imisinga lapho ngivakashela izindawo engingazijwayele.
Izinyathelo zokuqapha ngokumelene nama-rip currents
Ngenxa yokuthambekela kwabantu kokugwema ukubhukuda emanzini anolaka, izigameko zivame ukuvela lapho amagagasi enikeza umbono wokuzola. Ngokuka-Erik Heden, isazi sesimo sezulu esixwayisayo seNational Weather Service ye-National Oceanic and Atmospheric Administration (NOAA), ukufa okuningi kwenzeka ngezimpelasonto ezimnandi. Isimo sezulu ngokuvamile siyashisa futhi libalele, sidala inkohliso yokuphepha nezimo ezingasongelayo.
Ukuqinisekisa ukuphepha kwakho, ukuhlela okufanele kubalulekile. Thatha isikhathi sokuhlola isibikezelo samanje esiqondile esiqondene nendawo yakho, futhi uma kuboniswa ingozi enkulu, kuyafaneleka ukuyeka ukungena emanzini. Njengoba uHeden ephakamisa, mhlawumbe ukukhetha usuku echibini kungaba okufaneleka kakhulu.
Ngaphambi kokuthi uphumele emanzini olwandle, thatha isikhashana ubheke amafulegi okuphepha futhi uzijwayeze nezincazelo zawo, njengoba zingahluka kuye ngendawo okuyo emhlabeni. Ukwengeza, kuyatuseka ukubhukuda eduze komqaphi ukuze uphephe kakhulu.
U-Heden weluleka ngokuqinile ngokumelene nokubhukuda eduze kwamajethi noma amadokodo ngenxa yokuba khona kwamagagasi. Uma kwenzeka uzithola ubanjwe yi-rip current, nakhu okufanele ukwenze.
Uma ubanjwa yi-rip current, Isenzo sakho sokuqala kufanele kube ukuzama ukutshala izinyawo zakho ngokuqinile phansi olwandle. Uma ukwazi ukuthintana nephansi lolwandle, sukuma ngokushesha uqhubeke nokubuyela ogwini. Ngokuka-Cousens, ngokuvamile akunakwa ukuthi abantu bangase babe ngaphakathi ekujuleni kwabo lapho bezwa umuzwa wokudonselwa emanzini ajulile ngokugeleza kwamandla.
UHeden weluleka ngokuzama ukubhukuda ubuyele ogwini uma ungakwazi ukusukuma. Imisinga ingashesha ngendlela emangalisayo, ngisho nokudlula ijubane lombhukudi wama-Olympic, okwenza kungenzeki ukubadlula.
Zibambe ufune usizo. Ngokusho kukaBrander, ukuvumela ukwethuka kuphazamise ukuphefumula nokusebenza kahle komzimba okungaholela ekutheni ugwilize.
Ngokuka-Boxall, ake sicabange ngomsinga ogelezayo njengomfula ogelezayo. Esikhundleni sokuzama ukubhukuda uwele kuwo, njengoba ubungeke wenze ngomfula, bhukuda uhambisane nogu. Qhubeka ngale ndlela uze ubalekele ngokuphephile umsinga bese ubuyela ogwini.
U-Brander weluleka ngokuqapha lapho ebheka isiqondiso se-current. Kubalulekile ukuqaphela uma i-current ingena nge-engeli, njengoba ukubhukuda emaceleni kungabangela ukubhukuda ungaqondile ngokumelene nomsinga..
Ukuze wonge amandla futhi uvimbele ukukhathala, kunconywa ukuthi uthathe indawo entantayo emhlane wakho, uqiniseke ukuthi izindlela zakho zomoya zicacile. UCousens weluleka "ukuntanta ukuze uphile," egcizelela ukubaluleka kokuhlala uzolile, uphumule, futhi ululame ngenkathi ukulesi sikhundla.
Siza noma ubani oyidingayo
Uma kwenzeka uhlangabezana nomuntu ocindezelekile, kubalulekile ukuthintana ngokushesha nonogada, umnikeze umshini wokuntanta, futhi umqondise endaweni ephephile yokubhukuda.
Kunconywa ukuthi ungangeni emanzini ezimweni ezinjalo. UHeden uchaza ukuthi ukusabela okungokwemvelo kuwukunikeza usizo, kodwa inkinga isekutheni nini Uyazama ukubahlenga, ugcina usuba sengozini kuyilapho bona bengalimali.
Ukhiye wokuqinisekisa ukuphepha wukuba nolwazi ngezimo kanye nezinyathelo ezifanele ongazithatha uma kuhlangatshezwana nazo. Ngokusho kukaHeden, i-rip current akufanele yesatshwe, kodwa kunalokho ibhekwe ngenhlonipho enkulu.
Ngethemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nendlela yokubona nokubalekela ama-rip currents.
