Chii thermohaline riparadzirwe nyanza?

The zvachose nzvimbo nyanza - mvura goko Nyika - 361 100 000 km². Zviri imwe gadziriro, iyo ine zvipenyu, zvemakemikari uye chitarisiko, nokuchinja umwe kana mhiri penyanza "kurarama", iri Akave nokuvandudza uye rinoparadzirwa.

Nyanza - iri mvura, saka zvose zvayo maitiro mumuviri makemikari kuvimba nokuchinja zvakatipoteredza.

VaBennett mvura kuparadzirwa mugungwa

Water - iri Urume zvakasikwa zviri nguva dzose kugara zvitange. Riparadzirwe mvura mugungwa kunoitika nezvikonzero zvinoverengeka:

1. Riparadzirwe zvomumhepo - mhepo.
2. nyika kumativi ayo akabatana.
3. Igaroziva simba kukwezvana yomwedzi zuva.

The chikuru chinokonzera mvura rwokufamba ndiyo mhepo. Zvinokanganisawo mvura negurumwandira nyanza hunokonzera pamusoro dzenzvimbo, uye ivowo, uchatamisa kurema kuti dzakasiyana-siyana mugungwa. Nokuda womukati kukweshera nesimba pakati translational inofamba iri kune dambudziko akaturikidzana, uye naivowo, anotanga kufamba.

Wind inobata chete chenyika rukoko mvura - anosvika 300 metres pachiso. Uye kana okumusoro akaturikidzana vanotama yokutsanya zvakakwana, ipapo yakaderera zvishoma nezvishoma tinofamba uye kuvimba pasi kwakaita nzvimbo yacho.

Kana tikafunga mumakungwa seboka, zano dzenzvimbo unogona kuona kuti vari vaviri whirlpool guru, izvo dzakaparadzaniswa neequator. Muna Northern Hemisphere mvura unotii Kutenderera muna Southern - pamusoro. Panguva ano Continental varikumahombekombe ingasiyana pakuendeswa yavo. Uyewo, mwero kuyerera kumativi kumadokero pamhenderekedzo kupfuura pamusoro Oriental.

Dzenzvimbo haifambi nenzira yakarurama mutsetse, uye vakatsauka pane imwe nhungamiro: kuchamhembe hemisphere - rworudyi, uye muna South - negwara risiri. Izvi imhaka kuna Coriolis simba, iyo unovapo somugumisiro Dzenyika majana kumativi ayo akabatana.

The mvura mugungwa anogona vachamutswa uye ashaye. Izvi imhaka kukwezvana yomwedzi zuva, nekuti izvo pane ebbs uye Rwako. kuchinyanya yavo zvichisiyana mukati imwe nguva.

Thermohaline riparadzirwe nyanza

"Halina" rinoshandurwa kuti "salinity". Pamwe, mvura tembiricha uye salinity kuona arambe achirema kwayo. Water circulates munyanza, kuerera iri kubva mumvura inodziya iri Equatorial latitudes polar - saka Hot mvura yakavhenganiswa nemvura inotonhora. Uyewo, kubuda mvura inotonhorera iri kubva kuna polar kusvikira Equatorial latitudes. Izvi kunoitika dzose.

Thermohaline kuparadzirwa kunoitika panguva imwe kudzika panzvimbo dzapasi rukoko Rwako. Somugumisiro izvi zvaitika convective inofamba remvura - inotonhora, munhu rinorema mvura pairi uye inofamba nenzira dzinopisa. Saka, pose dzenzvimbo kufamba muna rimwe divi, uye kudzika - kune mumwe. Uye pane vakawanda makopi munyanza.

thermohaline dzenzvimbo

Pamusoro dzenzvimbo nyanza uchingounganidza kupisa pa neequator, uye kana uchifamba pamatunhu latitudes zvishoma nezvishoma haachandidi. Yakaderera latitudes, somugumisiro wacho kwemvura remvura kunowedzera chaizvo giravhiti, ayo salinity inowedzerawo ayo. Kusvika panguva polar latitudes, mvura Madonhwe vari vakaumba dzenzvimbo yakadzika.

Kune akawanda dzenzvimbo guru akadai Gulf Stream (kudziya), Brazilian (kudziya), Canary (chando), Labrador (chando), uye vamwe. The thermohaline akaparadzirwa ndiyo mumuitiro yose nemiitiro: zvose kupisa nokutonhora.

Gulf hill

Chimwe chikuru inodziya dzenzvimbo yepasi - Gulf Stream. It ane hombe kukanganisa okunze wokumusoro uye vokumadokero kweEurope. Gulf Stream anotakura mvura inodziya kuti yaro pamhenderekedzo kondinendi, saka anosarudza vade munyoro okunze mu Europe. The mvura iri ipapo dzaserera uye pairi, uye rakadzika rukova anotakura kuti neequator.

The nomukurumbira ice-isina chengarava Murmansk akadaro nokuda Gulf Stream. Kana tikafunga mashanu latitudes of Northern Hemisphere, unogona kuona kuti kumadokero chikamu (mu Canada) pane imwe Latitude ravakwa hasha okunze, inopfuura achinaya mvura mapazi ari Eastern Hemisphere iri rakafanana Latitude kukura masango Deciduous. Pedyo chaizvo inodziya miti zvichida kunyange kukura pamusoro, saka ushamwari okunze pano.

The simba pamusoro riparadzirwe kuyerera kunosiyana-siyana gore rose, asi zvinoitwa Gulf Stream anogara guru.

Sei okunze Pasi

Munzvimbo kuGungwa Weddell uye Norwegian runobva Equatorial latitudes mvura yakakwirira salinity. At dzakakwirira latitudes zviri dzaserera kusvikira oma pfungwa. Kana chando siyana, munyu haina zvaisanganisira mairi, saka kuti dambudziko akaturikidzana zvakawanda wakawanda uye batana. mvura kwakadaro anonzi North Atlantic kana Antarctic benthic rakadzika.

Thermohaline riparadzirwe nyanza kunoitika nenzira namahwindo ino.

Saka, isu vakagumisa kuti mukuru kudzama, kunokonzera arambe achirema mvura. Mugungwa tinyanye arambe achirema mitsetse anenge chinjikira. Mvura zvakasiyana mumuviri uye makemikari zvivako nyore manyukunyuku panguva dzose arambe achirema mutsetse pane naro.

The thermohaline kuparadzirwa anodzidzwa hakuna kunaka zvakakwana. Zvinozivikanwa kuti izvi kwete chete kunokanganisa mamiriro mvura munyanza, asi isina rinokanganisa ekunze Wepasi. All Hurongwa panyika yavharwa, saka kuchinja chimwe subunit alters mumwe.
