Dabaylo qabow badan Western

About 70% ka mid ah dunida dacaladeeda mashquulin Ocean World. Waxay si joogto ah waa in mooshin sarkhaansan yihiin muddo dheer ama muddo gaaban saamaynta asal ahaan kala duwan. dhaqdhaqaaqa noocan oo kale ah ee tacsida weyn oo biyo ah saamayn caalami ah cimilada ee ka qeyb this dunida iyo cimilada oo dhan dhulka. In Hemisphere Southern ah, soo-gaadhista sida uu hadda qabow xoog leh, u yeedhay Wind West ah fakadaan.

Sababaha hadda badda

biyaha badweynta aduunka ee gobolada kala duwan ee caalamka kala duwan heerkulka, cufnaanta, salinity, midabka, oo aan jir ahaan waxay noqon kartaa hal conglomerate ah. waxaa soo guurista waxaa badanaa keena saamaynta isku dhowr ciidamada simaha siyaabo kala duwan ugu kacay moolka kala duwan.

On dusha sare ee hadda badda ee factor ugu weyn ee waxbarashada - dabaysha jirta. dabaylo ganacsiga taas oo ay jihada a yara joogto ah, loo yaqaan sababta ugu weyn ee formation of laba durdurrada waaweyn, jihada Dhawrista muddo dheer: Northern iyo Koonfurta hadda Equatorial. Waxay biyo ah si ay duleedka galbeed ee ka Atlantic iyo Pacific, halkaas oo, taas oo ku xidhan qaab reer qaaradood, durdurrada shaqsi loo sameeyay gareeyeen. wareegga la aasaasay, taas oo taageero oo ay ku jiraan dabaylo monsoon in la afuufo xagaagii la badda ilaa dalkii ku, iyo xilliga qaboobaha - on lid ku ah.

Kulul iyo kuwa qabow

Badaha - qaboojiye Global ee caalamka, taas oo uu leeyahay dhowr hababka heerkulka. Ka mid ah noocyada of mooshinka translational oo biyo ah kala saaro socodka kulul iyo kuwa qabow. badda Heerkulka socodka - ma buuxda laakiin qaraabo. Diiri waxa ay taasi jawi qabow ah, hargab - socodka ah ee layers badda kululaynta iyo cimiladu kulul.

Caadi ahaan socodka ka dhulbaraha iska faray, ka latitudes sare si hoose - diiran. Haddii webigu ku dhashay koonfur ama Waqooyiga Dhulbadhaha iyo biyaha ee gobolka a qabow xanbaarsan yahay, waa - hadda qabow.

heerkulka Relativity hadda badda sifo la arki karo in tusaale ahaan ka mid ah laba hadda badda, oo ku yaalla qaybo soo horjeeda ee caalamka. Gulf Stream - badda ugu caansan waayo sameynta cimilada ee Northern Hemisphere ee, heerkulka biyaha waa in kala duwan oo 4-6 ° C iyo la xidhiidha diiran, xashiyihii kulul xeebta. hadda qabow waa xoog badan yahay Benguela - mid ka mid ah laamihii Wind West ah fakadaan. By Cape waxa biyaha qaada, kululayn jiray ilaa 20 ° C.

At soohdinta reer Antarctic ah

Dhaqdhaqaaqa baaxad weyn oo ka mid ah biyaha ee gobollada kala horjeeda ee Hemisphere ka Koonfureed - ugu awoodda badan caalamka. Waxay sameeyaan Antarctic Circumpolar (circum Laatiin - agagaarka + Polaris - horjeeda) gudahood, giraan ah oo joogto ah encircles meeraha xagga galbeed iyo bari. The socodka weyn ee qabow - content ugu weyn ee waxbarashada shuruud juquraafi - Ocean koonfurta, aasaasay biyaha, Pacific Hindiya iyo badaha Atlantic wareegsan Jacaylku.

Dhinacyada bangiyada ee qaaradda lixaad, 55 ° loolka koonfureed, soohdinta koonfureed ee baas shuruud il this, iyo xagga woqooyi ka waddaa weheliyaan barbar 40aad. Isgooyska ee biyaha xeebta ah ee qaaradda koonfurta daboolay by baraf iyo kulul xadad badda koonfurta dhashay dabaysha xooggan ee Hemisphere Southern qabow.

ciyaya afartameeyaha

Tani waa magac kale in uu yahay caalamka ee dabaysha Western.

Latitudes, oo ay la socdaan oo ay maamushaa hadda ugu weyn qabow, loo xilsaaray in ay dhowr koob oo aad u daran. "Afartameeyaha ciyaya 'hareerayn" dugaaggu ka dhex ciyaan "iyo" foosha xun "ee konton konton iyo" dalooliyo "demoqaraadiyad. Celceliska xawaaraha dabaysha aagga - 7-13 m / s. dabayl Beaufort cusub ah oo xoog badan u yeedhay, sida duufaan, iyo duufaan daran (25 m / s) - wax a caadiga ah.

Xoogbadane hadda circumpolar qabow, ma si loo daboolo caqabadaha qaaradda, dabaylo galbeed xoog iyo joogto ah u sameeyey loolka ee wadada ugu gaaban for sailboats. Halkan jiifay "wadada of clipper ah" oo la odhan jiray si ay maraakiibta nooca tsenivshihsya loo gaarsiiyo si dhakhso ah alaabta gumeysiga ka soo Hindiya iyo Shiinaha in Europe. Caanka ah "shaah" clipper dhigay diiwaanka xawaaraha qarniyo XVIII-XIX, haddii ay awoodaan in ay si guul leh circumnavigate caarada koonfurta Africa iyo South America ahaayeen.

width, dhererka, heerka socodka

Marine for Southern dabaysha dherer guud ee 30,000 km iyo 1000 km ee width uu leeyahay awood ah (heerka socodka volumetric) - .. 125-150 Sv (svedrupov), ie in ay u dhaqaaqdo socodka labaad ilaa 150 kun oo mitir kuubo oo biyo ah. Tani waa u dhigma oo leh awooda in ay tahay in meelo qaar ka mid ah Stream Khaliijka. Heerka socodka ee lakabka dusha sare ee biyaha badda - ka soo 0.4 si 0.9 km / h, si qoto dheer - 0.4 km / h.

heer-kulka biyaha Antarctic Circumpolar hadda waa kala duwan ee laamaha ugu weyn, ka dhaca oo saddex badood oo kala duwan. The West Wind miyigii waa:

• Falkland iyo hadda Benguela ee Atlantic ah.
• West Australian The - Badweynta Hindiya.
• hadda Peruvian Pacific.

In qaybta koonfureed ee durdur socodka ah ee lakabka sare ee heer-kul C 1-2 ° a, ee waqooyiga - oo 12-15 ° C.

On dusha sare iyo gudaha

Badaha - hal shaqeeyo a. Waxa la ogaaday in dhumucdiisuna oo dhan oo biyo ah badda waa in mooshin joogto ah. barakac dadban ayaa la dhammaystirayaa toosan marka kor u qaaday layers kulul badan ama ka yar oo cufan. Waxay sii wadaan in ay wax ka barato hadda qoto dheer hore u geli karin in inta badan waa soo horjeeda ee jihada dusha sare.

In 2010, saynisyahano Japanese helay xeebaha Jacaylku degaanka ee Adelie Land, dhaqdhaqaaq qarsoon oo xoog leh. In biyaha Badda Ross socodka ka barafka glaciers si ay u sameeyaan at qoto dheer ah 3000 mitir awoodda socodka ah ee 30 million m ³ / s ah. qulquli heerka - 0.7 km / h, iyo heerkulka biyaha + 0.2 ° C. Tani waa hadda qabow ee Badaha South ah.
