North Atlantic Current: makhalidwe ake ndi chikoka pa nyengo

Aliyense akudziwa kuti nyanja - si mapangidwe malo amodzi, madzi likuyenda nthawi zonse. Nthawi zina limayenda mu mawonekedwe a mtsinje waukulu, amene asayansi dzina lake ndi mafunde a nyanja. Mmodzi wa akuluakulu mu dziko ndi North Atlantic Current, tikambirana chiyani m'nkhani ino.

Ocean mafunde ndi malo awo mu envelopu Hrs a Dziko Lapansi

M'madzi (kapena nyanja) pa - mtsinje wa misa madzi ndi katundu zofanana dvizhushiysya mu njira imodzi. Chifukwa umene unakhazikitsidwa? Chifukwa mphepo zonse. Kotero pafupi ndi equator mu nyanja ya Atlantic, kuti limachokera amphamvu kwambiri nyanja panopa cha kumpoto kwa dziko lapansi - Gulf Stream. 45 madigiri kumpoto kumpoto ndi wotembenuka mu North Atlantic Current.

Koma kum'mwera kwa dziko, yaikulu ndi mphepo kumadzulo amene lazungulira lonse lapansi. m'lifupi zoyerekeza - makilomita zikwi zingapo, madzi ikuyenda pa liwiro la makilomita 3.5 pa ola limodzi. Akukhulupirira (ngakhale geographers onse kugawana udindo uwu), ndiko kuti, ndi malire a otchedwa Kumwera Ocean (chachisanu mu mzere, amene anayamba kuthera posachedwapa).

Nyanja mafunde oceanographers anaphunzira mwatsatanetsatane ntchito zipangizo zapadera, komanso luso Kanema. Envelopu Hrs wa dzikoli, iwo amagwira nawo ntchito yofunika kwambiri: kupereka kusamuka Ocean salt, kutentha, zamoyo, kulimbikitsa kusakanikirana madzi. Komanso, iwo kwambiri bwanji nyengo ya mayiko, makamaka m'madera awo m'mphepete mwa nyanja.

Amadziwika kuti otaya ozizira kumachepetsa kutentha pafupifupi pa magombe, imene iwo pochitika, ndi kutentha - ofunda kubweretsa gombe. Iwo zimakhudza kuchuluka kwa mpweya: ozizira - yafupika, ndi kutentha - kuwonjezeka.

Zo awo pa malo nyengo tikhoza kuona chitsanzo yosavuta kumva. Choncho doko Murmansk ndi ayezi basi chifukwa chakuti chiwerengero cha mipita ya North Atlantic Current. Ndipo apa pali malo driest pa dziko - ndi Atacama chipululu mu gombe South America - osati mwangozi anapanga kumene ozizira loyenda Peru panopa.

North Atlantic Current wake "zogona" pa map

Kuti tipeze kumene North Atlantic Current, m'pofunika ayang'ane pa khadi yoyenera. Ake "dziko", monga mmene taonera, ndi Atlantic Ocean.

Izi ndi amphamvu nyanja panopa ndi mbali ina ya Gulf Stream, zochokera ku dziko. Umayamba pafupi Grand Banks cha Newfoundland ndi amphamvu chimachititsanso mtsinje nyanja ya Atlantic mu kumpoto kum'mawa. Komanso, pafupi ndi cisumbu ca Ireland, izo amang'amba pawiri. ofesi ina (zotchedwa Canary Current) akutembenukira m'njira kum'mwera, ndi zina - akupitiriza kusuntha kumpoto-kum'mawa, skirting m'mphepete kumpoto kwa dera poto-European. Ngakhale patali, nthambi izi kugawidwa mu Irminger Current ndi Chinorowe.

Amenewa ndi madera la maphunzirowa. ndi mbali thupi komanso malo kuti amakhala chiyani?

North Atlantic Current: kutentha ndi madzi mlingo

Pa zimachitika konzekera, kutentha madzi ranges ku +7 kuti +16 madigiri Celsius. Ofunda North Atlantic Current kwathunthu utakhazikika okha Ocean Arctic, kusakanikilana ndi madzi ake. liwiro la kayendedwe ka madzi zimasiyanasiyana 1.8 Km / h, kum'mwera wa ku 0.4 Km / h kumpoto.

Tikumbukenso kuti zofunika thupi ndi malo zizindikiro North Atlantic panopa variable. Ndi kutentha ndi mathamangidwe wa madzi ndi mwamphamvu amadalira mphamvu ya Gulf Stream, amene nawonso, umaonekera kusintha lakuthwa mu nyengo ku Ulaya (makamaka yozizira).

Modern kumuopseza zachilengedwe

Gulfstream, makamaka North Atlantic Current, n'chofunikira yovuta kutchukitsa nyengo European. Choncho, mu dzinja kumakhoza kwambiri mitigates chisanu ndi m'chilimwe - kumachepetsa kutentha ndi kubweretsa kwambiri kuchuluka kwa mvula. Izi makamaka noticeable mu UK, pamene chifunga ndi yaitali drizzle anakhala zizindikiro pafupifupi dziko.

M'zaka zaposachedwapa, zachilengedwe ambiri akulankhula za chakuti North Atlantic Current ndipo mwina amasiya kuvuta. Chifukwa - Atlantic kusintha madzi amenewa ndi chachikulu mumapezeka madzi nyanja. geographers ena amakana kuti zimenezi, ndikungonena zokhuza kuthekera kuchepetsa mlingo otaya chifukwa zimenezi. Malinga ndi kunena kwa iwo, zinachitika kangapo mu zaka zikwi 50.

pomaliza

North Atlantic Current - imodzi yofunika kwambiri mu North Atlantic. Ndi chinthu chofunika kwambiri kwa nyengo European. Komabe, padziko lonse zachilengedwe mavuto a kuipitsa mafuta a madzi a m'nyanja, tisakhale linakhalapo.
