Cold watsopano wa Atlantic Ocean - ndi chiyani? Kufotokozera za mafunde ozizira a Atlantic

Atlantic Ocean - chigawo chimodzi cha nyanja dziko ndi mtsinje wamphamvu misa mpweya. Malinga ndi gawo azikhala, iye ali mu malo chachiwiri. M'dera madzi lili mabacteria osiyana nyengo. The kufalitsidwa misa utuluke mwa madzi ndi kutentha ndi kuzizira otaya ya Atlantic Ocean. Pa yotsirizira kunena payokha. Ndicho, za zimayambitsa awo ndi makhalidwe. Tiyeni tiyambe wodziwa kwambiri amafotokozera madzi.

Mafunde ya Atlantic

Atlantic Ocean (pa mapupa Tingaone momveka) amatsuka pafupifupi m'maiko. Mwachibadwa, zimenezi m'dera madzi ndipamene mbali nyengo ya m'madera amenewa m'dziko. Koma chifukwa chimene chikuchitika? A mbali yaikulu mu chitukuko cha nyengo ankaimba osati misa mpweya, komanso otaya. Ofunda nyanja akanagonjetsa kuzizira. Atsopano pa nambala pali 5 okha.

Mu Atlantic Ocean mafunde ndi peculiarity: iwo akusuntha mu mobwerera malangizo, kupanga mtsinje wamphamvu Kusintha kwa madzi ndi kuchotsa ofunda madzi ozizira. Chotero m'zinthu m'madzi ziwiri: mwa kumpoto ndi kum'mwera Hemispheres.

ndi panopa ozizira ya Atlantic Kodi Ocean (dzina)? Monga tidanena kale, zikuluzikulu kuonetsetsa 5:

1. Labrador.
2. Canary.
3. Benguela.
4. Falkland.
5. The West Mphepo Kuthetsa.

Kuthetsa West Mphepo

Cha Kumwera kwa dziko lapansi Atlantic Ocean makamaka kutchulidwa kwa mphepo Western. Dzina chachiwiri - Antarctic Circumpolar. Amaona amphamvu kwambiri ndiponso zazikulu otaya nyanja ya dziko lonse, kudutsa meridians onse a Dziko Lapansi. Iwo analanda osati unyinji wa madzi a Atlantic Ocean, komanso Indian ndi Pacific. M'litali otaya wa - 30 sq .. Km, m'lifupi - mpaka 1 zikwi makilomita.. Kutentha kwa madzi pamwamba mu mtsinje ranges pakati + 2 ° C m'madera kum'mwera kwa + 12 ° C - kumpoto.

Izi wamphamvu ozizira panopa wa Atlantic Ocean anali zotsatira za mphepo imene inkawomba ali Western. Kwenikweni, zilamulire m'dera m'dera kotentha m'dera pakati pa 35 ° S. yakumadzulo. kwa 65 ° S. yakumadzulo. Mphepo kuchokera kumadzulo kupita kum'mawa, ndi mphamvu m'nyengo yozizira, kupatula - m'chilimwe. Anaphulitsa mtunda onse kumpoto hemispheres Kumwera. Koma otsiriza a mphamvu zawo kangapo apamwamba chifukwa chakuti sakhala ndi malo chotchinga mu mphepo. dera lomwe chomveka Western mphepo kaŵirikaŵiri anaunika ngati osiyana Kumwera Ocean. Mlingo wa otaya madzi pamwamba wosanjikiza mpaka 9 m / s, mu zigawo kwambiri yafupika 4 m / s. Izi amapereka moyo kwa wina ziwiri kufalitsidwa misa ozizira: Benguela ndi Falkland.

pa Malvinas

Falkland Islands (Malvinas) - panopa ozizira ya Atlantic Ocean. Bifurcation Antarctic Circumpolar mtsinje. Kulekana naye m'dera pa nsonga ya. Tierra del Fuego. Pa njira chake, skirting gombe kum'mawa kwa Africa South America ndi Patagonia, umayenda pamodzi Islands ndi Falkland, itha dera La Plata Bay. Kenako, madzi amalowa ofunda Brazil panopa. The confluence a mitundu iwiri kufalitsidwa madzi zimasonyeza bwinobwino kuchokera kumwamba, ndipo ngati timaphunzira Atlantic Ocean pa mapu. Popeza kuti otaya madzi ozizira ndi wobiriwira, ndi ofunda - buluu.

mlingo Falkland otaya ndi zazing'ono - mpaka 1 m / s. Madzi kutentha pa - pakati + 4 ° C kwa + 15 ° C. Poyerekeza ndi kufalitsidwa misa ena ali m'munsi amenewa madzi - mpaka 33 ‰. Ichi ndi chifukwa chakuti otaya ku Nyanja Weddell kuti anayamba kuyenda namkholowa awo amene pang'onopang'ono kusungunula.

Benguela Current

Benguela - nthambi ina ya otaya ozizira pa nyanja akudzipatula ku West Mphepo Kuthetsa. Pamafunika kunayambira ku Cape of Good Hope ndi wakuti kumpoto, mathero a m'dera la Kachikumbu chipululu (Africa). Kenako anatembenukira kumadzulo, izo anazitsanulira mwa South Equatorial Current, motero kuthetsa vuto la misa kufalitsidwa mu Kumwera kwa dziko lapansi. Bengal madzi kutentha ndi zosiyana kwambiri ndi kutentha kwa madzi m'nyanja, ndi kuchepetsedwa ndi ° 3-4 yokha. mtsinje ali pafupi kwambiri m'mphepete kumadzulo kwa Africa. otaya malangizo ndi kumadzulo mphepo pachiyambi ndi mphepo ya mwera kum'mwera easterly m'tsogolo.

Labrador Current

Mu kumpoto kwa dziko lapansi ikuimira Atlantic ozizira - Labrador. otaya ili la madzi nyanja akuyamba ulendo wake ku Baffin Bay, wakuti pa. Newfoundland. Chitadutsa pakati Canada ndi Greenland. Kupita kuchokera kumpoto mpaka kummwera, pa mapeto a njira likukwaniritsa ofunda Gulf Stream. Chimakankhira madzi, akuwatumiza kum'mawa. Amadziwika kuti lili panopa ofunda zinthu zambiri yabwino nyengo ku Ulaya. Tikhoza kunena kuti ndi Labrador kumathandiza kuti ichi.

The moyandikana kwa Ocean Arctic ndi oundana amapereka yaing'ono otaya amenewa madzi 32%. Chifukwa cha Labrador Current kum'mwera kwa Atlantic kusambira namkholowa ambiri, complicating njira ya navigation mu zigawo izi. Onse a chinyozo Titanic inawombana ndi madzi oundana amene loletsa mu nyanja uwu.

Canary Current

Canary - panopa ozizira ya Atlantic Ocean. Iwo ali choyimira losanganikirana. Kumayambiriro a m'gulu lawo (pa gombe la kumpoto-kumadzulo kwa Africa ndi Canary Islands) kwa amanyamula madzi ozizira. Kenako, kusamukira kumadzulo, m'malo ozizira kutentha madzi konzekera ndipo m'kupita amalowa North Equatorial Current.
