La Ukusasazeka kweGulf ngumsinga wolwandle osusa ubuninzi bamanzi. Yeyona ibaluleke kakhulu kubantu baseYurophu, kuba enkosi kuyo sinokuqiniseka ukuba imozulu efudumeleyo ithathela ingqalelo ububanzi esizifumana sikuyo. Kodwa kwakhona, kuxhomekeke apho idlula khona, kuya kubakho iintyatyambo ezahlukeneyo kunye nezilwanyana, ezinamathambo amaninzi kunxweme olusentshona lweIberia kunokuba kungasenyakatho yelizwe, umzekelo.
Kungoko ke, okwangoku kuyinto enomdla kakhulu ukuyazi, ke siza kuyenza 🙂.
Yintoni iGulf?
IGulf Stella (e-Itali)
Ngaphambi kokungena kulo mbandela, kubalulekile ukuba uyazi ukuba yintoni iGulf. Ewe, kulungile inxalenye enkulu yamanzi engena emhlabeni y Oko kuphakathi kwee-capes. Bahlala bedidekile kunye neebheyi, kuba ayaziwa ngokuqinisekileyo ukuba uphi umda wale ndawo kunye neendawo ezinamacala, kodwa kuyaqondakala ukuba iindawo ezincinci zincinci.
Ngayiphi na imeko, ibaluleke kakhulu indawo, kuba kulapho kwakhiwa khona amazibuko neediksi.
Udlula phi iGulf Stream?
Lo ngumsinga wolwandle ovela njengesiphumo sokuhamba ngokujikeleza komhlaba, ukumiliselwa konxweme kunye nomoya wasemhlabeni. Iqala uhambo lwayo kwi-Straits yaseFlorida, kwaye isinge eYurophuNangona indawo apho iphelela khona ingekagqitywa, ukusukela oko kugqityiwe kungaphezulu okanye ngaphantsi kububanzi obungama-40ºN kunye nama-50ºW, apho amanzi ashushu anetyuwa aqhubeka nendlela yawo emantla kumantla e-North Atlantic, kunye INorway yangoku, kunye nomazantsi edlula kwiiCanary Islands zangoku.
Kumantla eAtlantic, amanzi ayo afikelela eNorway naseGreenland, apho apholisa ngokukhawuleza ngenxa yokusondela kwiPole. Ngokwenza njalo, baya kubaxinana ngenxa yomxholo wetyuwa ephezulu, ke bayatshona ngenxa yamandla omxhuzulane. Ke, yondla ukujikeleza kwe-thermohaline oko kungena nzulu.
Zithini iimpawu zayo?
Ngobubanzi obuqhelekileyo obuyi-80 ukuya kwi-150km kunye nobunzulu obuphakathi kwe-800 ne-1200m, amanzi ayo ahamba ngesantya esiphezulu se- 2 yeemitha ngomzuzwana njengoko isondela kwiindawo ezinzulu. Iqondo lobushushu liyahluka kakhulu kwimida ngenxa yokunxibelelana namanzi abandayo aseMantla kunye namanzi ashushu aseMzantsi. Ke, umzekelo, kumxinwa ohlukanisa iFlorida neBahamas kunye neCuba, iqondo lobushushu kumphezulu li-25ºC, ngelixa eNorway, kuLwandle lweBaltic, lumalunga ne-9ºC.
Ukusuka kwimvelaphi yayo ukuya kummandla weeBhanki ezinkulu, le yangoku ine Umbala oluhlaza okwesibhakabhaka nzulu kunye neetyuwa ephezulu, kodwa iyalahleka xa ixubana nomsinga we-North Atlantic. Ewe kunjalo, ukuhamba kwayo kuyamangalisa: kufutshane neIreland Izigidi ezili-150 m3 / s, eyenza ukuba ibe lelona lwandle linomdla kakhulu kwihlabathi. Ukusinika umbono, ukuhamba kwayo yonke imilambo engena kuyo yonke imilambo engena kwiAtlantic yongeza ukuya kuthi ga kwi-0.6 * 106 m3 / s.
Nje ukuba ifike eYurophu, yahlulahlula yaba yimifudlana emincinci enezinga lokuhamba phakathi kwe-10 ukuya kwi-20 yezigidi zeekyubhiki ngomzuzwana.
Zithini iiRings?
Umfanekiso-iZiko leNqwelomoya leNASA Goddard
Le yeyangoku ukuba xa yahlulwe kunxweme lwaseMelika iqala ukuhamba kakhulu. Ke, amanzi abandayo ahlukana namanzi oLwandle lwaseSargasso, kwaye ahlala esenza i-meanders enokufikelela kuma-350km. Xa bezivala ngokwabo bayabizwa Amakhonkco, enobubanzi obuphakathi kwama-50 nama-200km kwaye unokuhlala ukusuka kwinyanga ukuya kwiminyaka eliqela. Bahamba iikhilomitha ezimbalwa ngosuku, besiya eNtshona okanye besiya kwiIkhweyitha.
Zizinto ezixhaphakileyo kwimida yamanzi enobushushu obahlukeneyo. Bona usasaze ubushushu kunye netyuwa ukusuka kwenye indawo ukuya kwenye. Kwakhona, kufuneka kuthiwe kukho iiRings ezinee-cores zamanzi abandayo, kunye neeRings ezinamanzi ashushu. Iindawo zangaphambili ezihambela emazantsi kwaye zinzulu (phakathi kwe-4000 kunye ne-5000 yeemitha), zinethuba elide "lobomi" kunye nobubanzi obukhulu.
Kutheni le nto iGulf Stream ibaluleke kangaka eYurophu?
Ngaphandle kweGulf Stream, iYurophu ibingazukuhluka kangako kwiPole North. Ewe, ngekhe kubande njengaleyo, kodwa iya kubonakala kwiithemometha. Ngoba? Kuba ubungakanani bamandla obushushu obuqhutywa yile yangoku bulingana nobungqingqwa bayo, oko kukuthi, ukuba amanzi aphindwe kaliwaka kunawomoya, ithwala ubushushu obuphindwe kaliwaka kunomthamo ofanayo womoya. Ukuthathela ingqalelo ukuba le yangoku ithwala amanzi ashushu ukusuka kumanzi ashushu eFlorida ukuya kwilizwekazi elidala, banendima ebaluleke kakhulu kwimozulu yaseYurophu.
Kwaye yile xa isondela eYurophu, amanzi ashushu adibana nomoya obandayo. Lo mahluko kubushushu bolwandle uqobo kunye nomoya ojikelezayo ngulo umisela imeko yemozulu yendawo edlula kuyo, hayi eYurophu kuphela, kodwa kwihlabathi ukusukela kumoya obandayo ovela eNtshona yeNorway, xa usiya kulo kwaye Inceda ukuzinzisa ubushushu beplanethi.
Ndiyathemba ukuba ufunde ngakumbi malunga neGulf Stream 🙂.
