Amaza

Amaza

Zonke okanye phantse zonke zivile nge amaza elunxwemeni. Yinto eyenzeka ngamaxesha athile kwaye iyakwazi ukuhambisa isixa esikhulu samanzi kungena okanye ngaphandle konxweme. Amandla anyanzeliswa yintshukumo yamanzi ngumxhuzulane wenyanga kunye neLanga emhlabeni. Inyanga yisathelayithi eneyona nto inamandla kula maza kwaye idityaniswa ngumtsalane weLanga, onobunzima obukhulu ngakumbi.

Kule nqaku, siza kuchaza indlela amaza akhiwa ngayo kwaye axhomekeke ntoni. Ukongeza, siza kuthetha malunga nokuba ziyintoni iitafile zamaza kunye nokusebenziseka kwawo ekulobeni imidlalo. Ngaba uyafuna ukwazi ngakumbi ngayo?

Zisebenza njani

Amaza entwasahlobo

Zombini iintshukumo ezenziwa yinyanga eMhlabeni zidityaniswe neLanga, kufuneka sidibanise iziphumo ukuhamba komhlaba ezinje ngokujikeleza nokuguqula. Intshukumo yokujikeleza inamandla esiwaziyo njenge-centrifugal. Nangona imikhosi emininzi isebenza ekuveliseni le nto, ngaphandle kwamathandabuzo inyanga inamandla amakhulu.

Amaza asebenza ngokujikeleza. Kuba kuthabatha iiyure ezingama-24 ukuba uMhlaba ujikeleze ngokwawo ngokupheleleyo, uyakube uhambelana ngokupheleleyo nenyanga. Ingqiqo isixelela indlela Kufuneka kubekho umjelo omnye kuphela (umsinga omkhulu wamanzi) yonke imini. Kodwa oku akunjalo. Kukho amaza amabini aphakamileyo aneeyure ezili-12 zemijikelezo kunye namaza asezantsi (umsinga ophantsi) phakathi. Kutheni le nto isenzeka kwaye ingeyiyo eyokuqiqa?

Siza kuchaza inyathelo ngenyathelo. Njengokuba uMhlaba nenyanga zenza inkqubo ejikeleza kumbindi wokujikeleza, yinyanga etsala amanzi xa emi nkqo nkqo, ke ngoko, ayenyuka. Kwelinye icala lomhlaba Kuya kwenzeka okufanayo ngenxa yamandla e-centrifugal aveliswe yintshukumo yokujikeleza komhlaba. Olu tide luphezulu lwenzeka kwelinye icala loMhlaba alunamandla kangako.

Nangona kunjalo, kubuso obungahambelani nenyanga, kwenzeka okwahlukileyo. Amandla omxhuzulane kunye ne-centrifugal ayaphikisana kwaye akhokelela kumaza aphantsi.

Umjikelo wamaza

Ukusebenza kwamaza ngelanga nenyanga

Kufuneka sicinge ngokuhamba komhlaba ukuze siwuqonde kakuhle lo mjikelo. Ngokujikeleza kwi-axis yayo yokujikeleza, inyanga ikwajikeleza umhlaba ngokuguqulela. Kuthatha malunga neentsuku ezingama-29 ukugqiba ukujikeleza kwayo. Le nto yiyo ebangela ukuba uMhlaba ungangqinelani nenyanga rhoqo emva kweeyure ezingama-24, kodwa endaweni yoko ithatha ixesha elide (ngaphezulu okanye ngaphantsi kwemizuzu engama-50). Le nyani ibizwa ngokuba yinyanga kwaye yiyo ephawula umjikelo wamaza.

Ngoko ke, Umjikelo opheleleyo phakathi kwamaza amakhulu kunye nomsinga omkhulu ziiyure ezili-12, ngelixa umsinga ophakamileyo nophantsi ziiyure ezingama-6. Oku akusoloko kuchanekile, kuba iplanethi yethu ayenziwanga ngamanzi kuphela. Kukho umhlaba ongaphezulu kunye nezinto ezingahambelaniyo ezichaphazela amaza. Ikwachaphazela ijiyometri yamanxweme, ubunzulu beendawo zonxweme, i Imisinga yolwandle, umoya owenza ngalo mzuzu kunye nobubanzi esikuso. Ngamanye amaxesha uxinzelelo lomoya ludlala indima.

Iindidi kunye netafile yamaza

Amaza aphezulu kunye namaza asezantsi

Njengokuba besesitshilo, ukutsalela inyanga yeyona nto inamandla emanzini. Kodwa kukho iintlobo ezininzi zamaza. Kwelinye icala, sinayo amaza entwasahlobo. Luhlobo olubhengezwe ngakumbi lomsinga ophakamileyo nowaphantsi owenzeka xa inyanga nelanga zihambelana noMhlaba. Ngaba kunjalo xa yomibini imikhosi itsala amanzi ngobukhulu obukhulu kwaye ngakumbi ukubonakaliswa kwamaza aphezulu naphantsi ayenziwa.

Isichasi siyinyani. Xa iLanga nenyanga zikwikona elungileyo, imikhosi enomtsalane incinci, ke isenzo somxhuzulane sincinci. Kula maxesha xa amaza emancinci kwaye abizwa ngokuba yi-neap tide. Ukuba ezinye zeenguqu ezichaphazela amaza akhankanywe apha ngasentla anexabiso elikhulu uqhwithela.

Iitafile zamaza Ziindibaniselwano zeeyure zamaza aphezulu naphantsi. Ziluncedo kakhulu ekucwangciseni ukuloba kwezemidlalo. Ndiyabulela kwezi tafile ungalazi ixesha ekuya kwenzeka ngalo lamaza aphezulu kunye naphantsi. Ukongeza, umsebenzi wentlanzi uqikelelwa ukuba uyanda okanye awunakuba nawo amathuba okufumana okulotyiweyo.

Nanku umzekelo wetafile yomsinga:

Itafile yeTide

Ngaba kukho amaza eLwandle lweMeditera?

Isenzo senyanga kumaza

Xa kuthelekiswa nolunye ulwandle kunye neelwandlekazi, amaza aphezulu naphantsi akathakazeliswa kuLwandle lweMeditera. Kungenxa yokuba lulwandle oluvaliweyo. Kulungile ukuvulwa kweStrait yaseGibraltar apho kukho ukutshintshiselana kobuninzi bamanzi noLwandlekazi lweAtlantic.

Umjelo usebenza njengohlobo lwempompo evala ukuhamba kwamanzi kwaye ayivumeli amaza ukuba abekho ngolu hlobo lubhengeziweyo. Ngokudlula kumthamo wamanzi kwindlela emxinwa, unobangela kukuba kukho imisinga yolwandle eyomeleleyo kodwa azikhawulezi ngokwaneleyo ukutshintsha amanqanaba amanzi kakhulu kwinto edlula kwimijikelo.

Ngexesha lokuchitha, kwenzeka okwahlukileyo. Kukho ukuphuma okukhoyo ngoku okukhokelela kwiAtlantic. Ke ngoko, kuba iMeditera lulwandle oluncinci kwaye luvaliwe, nangona amaza aqatshelwa kwinqanaba lonxweme ukuze anyuke okanye awe iisentimitha, ayikuguquki ukuhamba. Kuyinyani ukuba nabani na oselunxwemeni lolwandle uyakulubona utshintsho imini yonke. Kodwa ngaphaya koko, ayinamsebenzi.

Ndiyathemba ukuba ngolu lwazi ungafunda ngakumbi malunga nokuba yintoni amaza kunye nendlela abasebenza ngayo.
