North Atlantic hadda: sifooyinka iyo saamaynta ay ku cimilada

Qof walba waa ogyahay in Badda - ma ahan formation a ma guurto ah, biyaha waa in mooshin joogto ah. Mararka qaarkood waxaa guuro qaab durdur ballaadhan, oo cilmibaadhe oo loo magacaabay by hadda badda. Mid ka mid ah waaweyn ee dunida waa Atlantic Waqooyiga ee hadda, oo laga wada hadli doonaa in this article.

Ocean hadda iyo meesha baqshadda juquraafi dhulka

Marine (ama Badda) inta lagu jiro - il of tacsida biyaha la guryaha isku dvizhushiysya in hal jiho. Sababtoo ah kuwaas oo waxaa la sameeyey? Sababo la dabaysha joogto ah. Sidaas dhow dhulbaraha ee Badweynta Atlantic ah, waxa u billaabay ugu awooda badan ee hadda badda ee u Safra waqooyiga - Stream Khaliijka. About 45 digrii loolka woqooyi, waxaa diinta ee Atlantic Waqooyiga ee hadda.

Laakiin koonfureed ee dhulbaraha, ugu weyn waa dabaylo galbeed oo encircles oo dhan dacaladeeda. Its width qiyaas - dhowr kun oo kiiloomitir, iyo biyaha ay u guurayaan xawaare ka mid ah 3.5 kiiloomitir saacaddiiba. Waxaa la rumeysan yahay (in kastoo oo dhan geographers wadaagin booska this), in uu yahay, waa xuduudda oo ka mid ah wax-u Koonfurta Badweynta (shanaad oo xiriir ah, taas oo bilaabay inuu sooco more dhawaan).

Badda hadda oceanographers bartay si faahfaahsan iyadoo la isticmaalayo weelal gaar ah, iyo sidoo kale technology satellite. baqshadda juquraafi ahaaneed ee adduunka, waxay ka ciyaaraan door aad u muhiim ah: bixinta a cusbada Ocean socdaalka, kulaylka, noolaha, kor u qasin biyo ah. Waxaa intaa dheer, waxay si weyn u saameeya cimilada ee qaaradood, gaar ahaan goobaha ay xeebta.

Waxaa la og yahay in qulqulka qabow yaraynaysaa heerkulka celceliska on soohdimaha, oo ay la socdaan oo ay Marayaan, iyo diiran - diiran keenaan xeebaha. Sidoo kale waxay saamayn ku yeelan xaddiga roobabka: qabow - dhimay, oo kulaylka - kordhay.

In raadka ay ku leeyihiin meelaha cimilada waxa aan arki karnaa tusaale fudud. Sayidka, dekedda ee Murmansk waa baraf-free kaliya sababtoo ah xaqiiqda ah in tiro ka mid ah baas ee Atlantic Waqooyiga ee hadda. Oo halkan waa meesha ugu qalalan on meeraha - Desert Atacama ee xeebaha South American - ma by fursad sameeyay halkaas oo qabow ah dal hadda Peruvian.

North Atlantic hadda, uu "deganaansho" on map dunida

Si aad u ogaato meesha Atlantic Waqooyiga ee hadda, waxaa lagama maarmaan ah in ay eegaan kaarka ku haboon. Its "hooyo", sida laga arki karaa, waa Badweynta Atlaantik.

Tani waa awood badweynta hadda waa qayb ka mid ah Stream Khaliijka, asal ahaan ka soo dhulbaraha. Waxa uu bilaabo dhow Grand Banks ee Newfoundland iyo durdur awood u dhaqaaqdo guud ahaan Atlantic ee waqooyi-bari. Dheeraad ah, u dhaw jasiiradda of Ireland, waxa jajabiyaa laba qaybood. Mid ka mid ah laan (yeedhay Canary hadda) jirsado jihada a koofureed, oo tan kalena waxay - waddaa in ay u guuraan waqooyi-bari, albaaka ku laayeen waqooyi ee gobolka digsiga-Yurub. Xitaa dheeraad ah, laan this mar kale u qaybsan hadda Irminger iyo Norway.

Kaasi waa juqraafiga ee koorsada. Maxay yihiin astaamaha jirka iyo juquraafi waxaa lagu gartaa?

North Atlantic hadda: heerka kulka iyo socodka biyaha

Inta lagu jiro loo aaneeyey inay u kululee, heerkulka biyaha halkaas ka +7 in +16 degrees Celsius u dhaxeysa. The diiran North Atlantic hadda si buuxda loo qaboojiyey kaliya ee Ocean Arctic ah, mingling la biyaheeda. xawaaraha dhaqdhaqaaqa ee biyo ku kala duwan tahay 1.8 km / h, ee qaybta koonfureed ee ilaa 0.4 km / h ee waqooyiga.

Waa in la ogaadaa in tilmaamayaasha aasaasiga ah jirka iyo juquraafi North Atlantic variable hadda. Oo heerkulka iyo xawaare biyaha waa si xoog leh ku tiirsan xoogga Stream Khaliijka, taas oo, markeeda, waxaa ka muuqda isbedel fiiqan ee xaaladaha cimilada ee Europe (gaar ahaan xilliga qaboobaha).

hanjabaad deegaanka Modern

Gulfstream, gaar ahaan North Atlantic hadda, kaalin muhiim qaabaynta cimilada Yurub. Sidaas daraaddeed, in xilliga qaboobaha waxaa si weyn u mitigates qabow iyo xagaaga - yaraynaysaa kulaylka iyo keentaa qadar weyn oo roob ah. Tani gaar ahaan waa la dareemi karo ee UK, halkaas oo ceeryaanta iyo meelsare oo sii dheerayn noqday calaamadaha ku dhowaad qaranka.

Sanadihii la soo dhaafay, deegaan sii kordheysa hadalka ku saabsan xaqiiqada ah in North Atlantic hadda waxaana laga yaabaa in dhammaantiis la joojiyo. Sababta - Atlantic isbedel salinity biyaha iyo weyn daatay biyaha badda. geographers kale diidi suuragalnimada in this, iyagoo leh kaliya oo ku saabsan suurtagalnimada of yaraynta heerka socodka sabab u ah arrimo kuwan. Tani, sida laga soo xigtay iyaga, ayaa ka dhacay in ka badan hal mar in 50 kun oo sano ee ugu dambeysay.

Gebogebadii

North Atlantic hadda - mid ka mid ah kuwa ugu muhiimsan ee North Atlantic. Waa muhiimad weyn u cimilada Yurub. Si kastaba ha ahaatee, dhibaatooyinka deegaan ee caalamiga ah ee la xidhiidha saliiddu wasakhayso biyaha badda, khatar jiritaankeeda.
