Benguela wamanje: Incazelo kanye nezici

Benguela yamanje - abandayo kwabo amanzi afundwa kakhulu lwe-Afrika olusentshonalanga e-Atlantic Ocean. Ugeza engxenyeni esentshonalanga ye zwekazi, ivela eningizimu futhi egijimela enyakatho, kwase kuba kwabayishumi enyakatho-ntshonalanga. Ngesikhathi ukunyakaza, ukusakaza esiqhubekayo Imimoya Western nokudlula eNingizimu Equatorial. Nokusakazwa amanzi iqala ukuya eningizimu eCape of Good Hope. It iphela ngaso endaweni engasogwini Lasogwadule LwaseNamibia Esibamba Amanzi Ugwadule, esemgwaqweni engxenyeni esentshonalanga ye-Afrika.

Izinga lokushisa, ukugeleza kanye nokuvulwa

I lokushisa ukugeleza ebusweni ehlobo 18 + ... + 19 ° C eningizimu futhi +26 ° C, eNorth. Ebusika Benguela selehlile +15 ... + 22 ° C, ngokulandelana.
amanzi Isivinini zokhahlamba kusuka 1-2 km / h, esingeqile 20-25 cm / umzuzwana. ezingeni usawoti - 35-35,5 ppm.

James Rennell kwelinye izincazelo bokuqala ukugeleza engavamile ngasogwini Afrika. Emuva ngo-1832, wabhala mayelana Yiqiniso, wasinikeza igama "eseNingizimu Atlantic Benguela zamanje." Rennell wabhala ke wabe nasogwini eNtshonalanga Afrika, izinikele ibhande enkabazwe ke balibhekisa entshonalanga, baba Equatorial yamanje.

Izici Ezihilelekile Kule Benguela yamanje

Phakathi kubhekwe ababuthakathaka, azithele ngabandayo. Amanzi abandayo ageleza ukunweba amakoloni isiphetho Penguin Afrika ukuze 30 ° latitude eningizimu.

Benguela zamanje asitholayo i izenzakalo okungavamile ngaphansi kwethonya emkhathini. "Benguela Nino" - okubizwa ngokuthi isimangaliso esifanayo baya ePacific ukubonakaliswa okufanayo emanzini eduze Peru - El Niño. Make babe 3 amacala elafika ngo-1934, 1963, 1984. Ububanzi Benguela ukugeleza ifinyelela 200-300 km eningizimu kancane kancane kwanda ngasenyakatho, lapho kuyinto 750 km.
Kuyaziwa ukuthi omunye wemithombo ukugeleza kubhekwa i-Indian Ocean (25% we mass adluliselwe).

ulwazi olwengeziwe

Ukuze umthelela esimweni sezulu, ngenxa yalokho kwezulu akuvamile. Lokhu kungenxa emoyeni abandayo, okuyinto luthe ukuqina, kanti ngoyisiwula kusinda kunakho efudumele.

Ukunyakaza kwabantu noma izithunzi amanzi kubonakala ngokucacile kungagcini in mpumalanga amabhange kanye has kunezinxushunxushu ngaphezulu, nemvelo oluyingozi engxenyeni esentshonalanga. amavolumu yamanzi 20-25 Sv. Zonke uhamba zabo Benguela yamanje. Kukuyiphi ocean usengayibona kulezi zici? Kuba nezinguquko eziphawulekayo izinkomba ezinjalo awuzibhebhezeli. Ukusetshenziswa gidroanaliza Imiphumela ibonisa ukuthi ushintsho umthamo luphakathi 20%.

Lezi zazi zazithole khona asebenzayo vortex mesoscale ensimini. Siqukethe anticyclone izindandatho ezinkulu nge isikhungo efudumele futhi izimpawu asemkhathini we kwemizi abandayo.

Finyeta, singakwazi ukunikeza impendulo noma ubani abanesifiso sokwazi: Benguela yamanje - efudumele noma ezibandayo? Nakanjani kuyabanda, kuyilapho izici enamandla kakhulu, okuyinto kakade eshiwo ngenhla. Ukugeleza yaziwa isikhathi eside, kodwa ucwaningo eningiliziwe hydrologists yayo, ososayensi baqala esanda kutholakala. Ngesikhashana nje sakwazi ukuthola umsuka waso nokwanda ukunikeza incazelo encane. Futhi lokhu neqiniso lokuthi ngoba eqinile ngempela, futhi lokhu kumelele usongo navigation.
