Ocean maqhubu 'me sebakeng sa bona ka enfelopo libaka ea Lefatše

Marine (kapa leoatle) nakong - na le molapo oa matšoele metsi le thepa tsoanang dvizhushiysya ka tataiso e 'ngoe. Ka lebaka la tseo e thehoa? Ka lebaka la meea e sa khaotseng. Le haufi le equator ho ea Leoatleng la Atlantic, e simoloha matla ka ho fetisisa a leoatle morao-rao tsa Lefatše ka leboea - Koung Phallela ho Eona. Ba ka bang 45 likhato leboea equator, e sokolohela ho North Atlantic Current.

Empa ka boroa ho equator, e kholo ka ho fetisisa ke ea meea e westerly eo encircles kaofela bophara. bophara ba eona e lekantsoeng - km 'maloa tse sekete,' me metsi a e tsamaea ka lebelo la km 3,5 ka hora. Ho lumeloa (le hoja li sa jeokrafi tsohle abelana boemo ba ena), e le hore ke, ho e leng moeli oa ho thoeng Southern Ocean (ea bohlano ka mola, le ileng la qala ho sebelisa sa tsoa feta).

Leoatle maqhubu oceanographers ithutile ka ho qaqileng ho sebelisa lijana tse khethehileng, hammoho le thekenoloji sathelaete. The enfelopo libaka tsa lefatše, ba ile ba phetha karolo ea bohlokoa haholo: ho fana ka ho falla Ocean matsoai, mocheso, lintho tse phelang, ho kgothalletsa ho kopanya tsa metsi. Ho phaella moo, ba haholo ama boemo ba leholimo ba lik'honthinenteng, haholo-holo libakeng tseo e lebōpong la leoatle.

E o tsejoa hore phallo batang fokotsa mocheso karolelano ka mabopo, hammoho eo ba feta, 'me mofuthu - mofuthu tlisa le lebōpo. Ba ile ba boela ama ka tjhelete e ya pula: batang - fokotswa, le mocheso - eketsang.

North Atlantic Current: mocheso le phallo ea metsi sekhahla

Nakong ngotsoe ke mofuthu, mocheso metsi na ranges ho tloha +7 ho +16 likhato Celsius.
