amagagasi ayisikwele

Ulwandle luletha izingozi ezithile kubantu ababhukuda kuzo. Enye yalezi zingozi amagagasi ayisikwele. Kuyisimanga ukuthi, isikhathi esiningi, akubonakali ngaphandle, kodwa kwenzeka olwandle. Akuvamisile ukubanga izinkinga ngaphandle uma zisuka phezulu. Kulezi zimo, kungaholela ekufeni futhi kudale ingozi enkulu.

Ngalesi sizathu, sizonikezela lesi sihloko ukuze sikutshele ukuthi ayini amagagasi ayisikwele, ukuthi iyini imvelaphi yawo, imiphumela nokuthi ungawagwema kanjani.

Ayini amagagasi ayisikwele

Igagasi lesikwele, noma elibizwa nangokuthi "izilwandle ezinqamulayo", Kuyisimanga esenzeka lapho imisinga emibili yolwandle ishayisana ngesivinini esikhulu nangamandla amakhulu.. Olwandle, amagagasi afana ne-chessboard, njengokungathi adweba imigqa emanzini.

Lezi zinhlobo zezenzakalo zenzeka ekujuleni kolwandle, ngakho azivamile futhi ukuba khona kwazo akusho inkinga. Nokho, lapho lesi senzakalo senzeka phezu kolwandle, singabangela izinkinga ezinkulu ngisho nokufa. Amagagasi alolu hlobo avamile e-Ile de Ré eFrance, lapho le "crossover" ivame ukwenzeka khona. Lezi zenzakalo zasolwandle zibonakala ngamagagasi ashayeka emanzini futhi akhe izikwele.

Kuwebhusayithi yayo, i-European Space Agency iyachaza ukuthi:

    “Isimo solwandle esinamagagasi amabili ahamba ngama-oblique angles sibizwa ngokuthi ukukhukhumala. Ukuwela isimo solwandle sekube nentshisekelo ethile emphakathini wamagagasi olwandle. Izimo zivame kakhulu olwandle futhi zenzeka lapho amagagasi nokukhukhumala, noma izimiso ezimbili zokukhukhumala, kuhlangene.”

Lesi yisimo esiyivelakancane esingakheka futhi sihlakazeke emizuzwini embalwa, ukwakheka kwayo kuncike ekumeni kwesimo sezulu endaweni, okubangela amagagasi akheke ema-engeli ahlukene, futhi uma eshayisana, akha le phethini yegridi.

Kwenzeka futhi lapho umoya udonsa amagagasi ohlangothini olulodwa futhi amagagasi awaphushele ngakolunye uhlangothi. Ngokuqondene nososayensi, babona lesi simo njengesibonelo se-equation ye-Kadomtsev-Petviashvili. Lena ingxenye yezibalo ehlukanisayo echaza ukushintshashintsha okungaqondile, okuvame ukusetshenziselwa ukuchaza ukusebenzisana kwezinhlelo zesimo sezulu.

Zakhiwa kanjani

Amagagasi avamile akha igridi olwandle njengokungathi ibhodi le-chess. Lawa magagasi angavamile futhi ayivelakancane akhiwa ukushayisana kwezilwandle ezimbili ezijulile eziyizinkulungwane zamamitha ukujula, futhi ezinye izici ezifana nomoya zenza amagagasi ahambe ibanga elide kangangokuthi ubuso bolwandle bubukeka buxakile.

Ngenxa yalokho, le mithelela yenza idayimane noma iphethini yesikwele eyenza i-Ré ibe enye yezindawo ezinhle kakhulu emhlabeni. Kuyathakazelisa ukuthi abantu abaningi baya e-lighthouse yalesi siqhingi, eyakhiwa ngo-1854, ukuze babone lesi sigameko esimangalisayo. Nakuba amagagasi ayisikwele emuhle, futhi ayingozi kakhulu, kunconywa ukuthi ungabhukudi kulezo zindawo.

Ubungozi bamagagasi ayisikwele

Lapho lesi senzakalo senzeka, sidonsa izinkulungwane zezibukeli ngenxa yombono waso othakazelisayo, nokho, ochwepheshe baxwayisa ngokuthi la magagasi empeleni ayimisinga yamanzi, ngakho angaba yingozi kunoma isiphi isikebhe noma kumuntu osemanzini.

Endabeni ye-Ile de Ré, izikebhe eziningana ziye zabikwa ukuthi zibanjwe yile misinga, noma kunjalo, kube nezigameko kwezinye izingxenye zomhlaba ngenxa ye "square sea", okuyizona iziphathimandla ezikhiphe isexwayiso ngazo.

Ngalo mqondo ongoti sebexwayise ngobungozi baso base beluleka ngokuthi uma ubona lesi sigameko kuhle ukugweme ukuba selwandle ngesikhathi somcimbi ukuze ugweme ingozi.

Uma izimo zezulu zivumela lesi simo ukuba siqhubeke isikhathi eside, izikwele zingabonakala phezu kolwandle, kodwa uma lokhu kwenzeka imikhumbi ingabambeka. Ucwaningo luka-2004 olwenziwa ngu-Toffoli, oluqoqa uchungechunge lwedatha evela kwa-Lloyds Marine Information Services phakathi kuka-1995 no-1999, lwembula ukuthi amaphesenti amakhulu ezingozi zemikhumbi abangelwa amagagasi ayisikwele.

Kungani kufanele zigwenywe?

Sizoqala ngokucaphuna ingcaphuno yencwadi ethi “The Science of Waves: Ripples, Tsunami, and Stomy Oceans”:

    "Izitimela ezimbili zamagagasi ezinobude obufanayo kodwa ziwela ngezindlela ezihlukene (ezinqamula izilwandle) zakha iphethini yokuphazamiseka eholela kumagagasi aphezulu ngokungavamile."

Ngokocwaningo, izinga okwenzeka ngalo izingozi eziningi zemikhumbi olwandle libhekana nezinguquko ezisheshayo zesikhashana. Ikakhulukazi ezimweni ze-transoceanic, noma ngemva nje kwe-transoceanic, “lapho amagagasi nomoya wasolwandle kucishe kulingane”.

Ngamafuphi, abageza kanye nabagibeli bezikebhe abazisabi bona lezi zingozi, kodwa ngenxa yokuthi kungenzeka bavaleleke ebhokisini elinephethini. Ngakho-ke, abahlengi bezilwane bayeluleka ngokungena emanzini ukuvimbela lokhu kuziphatha. Uma usungaphakathi kungcono ukubhukuda uye ogwini ngokushesha ngangokunokwenzeka.

Izindawo lapho kukhona amagagasi ayizikwele

Amagagasi ayisikwele awuhlobo lwamagagasi ongafuni ukuhlangana nawo lapho ubhukuda noma untweza. Kodwa okumangazayo ukuthi abantu abaningana basahamba bayozibonela lesi senzakalo esingandile. Njengoba lawa magagasi athile ewumphumela wokunqamuka kwamagagasi kanye nokuhluka, ngokuvamile avela ezindaweni ezisogwini noma phakathi kwamatheku amancane. Indawo edume kakhulu lapho kungabonwa khona la magagasi yi-Ile de Ré. Noma kunjalo, awukwazi ukulindela ukubona igagasi lesikwele 100% wesikhathi. Uma ufuna ukubona la magagasi, kufanele uqale ubuke ilogi ukuze ubone ukuthi kungenzeka nini kwenzeke.

Kunezindaba nezihloko ezithi lesi siqhingi esincane saseFrance siwukuphela kwendawo lapho siwela khona ulwandle, noma kunjalo, lokhu kungamanga ngokuphelele. Ungabona futhi lawa magagasi ayisikwele eTel Aviv naseLisbon ePortugal. Kulezi zindawo, izivakashi zivame ukundiza ama-drones phezu kolwandle noma zigibele ezindlini zezibani ukuze zibone amagagasi ngeso lenyoni.

Kungenzeka futhi ukuthi uke wawabona amagagasi ayisikwele eduze nogu futhi awazi nje. Amagagasi ayisikwele angashoni aphephe kakhudlwana ngoba aphatha amandla amancane.

Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana namagagasi ayisikwele, izici zawo kanye nezingozi.
