La Gulf Stream ndiyo yemvura yegungwa iyo inotsiva huwandu hwakawanda hwemvura. Iyo inonyanya kukosha kune veEuropean, nekuti nekuda kwayo tinogona kuva nemamiriro ekunze anodziya tichifunga nezve latitude yatinozviwana tiri. Asi zvakare, zvinoenderana nekwaanopfuura, pachave nemiti nemhuka zvakasiyana, iine arthropods kumahombekombe ekumadokero eIberian Peninsula pane asiri kuchamhembe kwenyika, semuenzaniso.
Izvo, saka, irizvino iyo inonakidza kwazvo kuziva, saka tichazviita 🙂.
Chii chinonzi Gulf?
Gulf Stella (Itari)
Usati wapinda mune iyi nyaya, zvakakosha kuti uzive kuti chii Gulf. Zvakanaka, zviri chete chikamu chikuru chemvura chinopinda muvhu y iri pakati pemusoro. Ivo anowanzo kuvhiringidzwa nemabhesi, nekuti hazvizivikanwe chaizvo kuti muganho weiyi nemumapapu uripi, asi zvinonzwisiswa kuti iwo mabheji madiki.
Chero zvazvingaitika, iyo yakakosha nzvimbo nzvimbo, nekuti ndipo panovakwa madoko nemadoko.
Iyo Gulf Stream inopfuura kupi?
Iyi inguva yegungwa inotangira semhedzisiro yekufamba kwekutenderera kwepasi, kurongeka kwemahombekombe nemhepo yepasi. Inotanga rwendo rwayo muStraits yeFlorida, uye inonanga kuEurope, kunyangwe nzvimbo chaipo painoperera haisati yatemwa, sezvo kupera kwayo kuri kwakawanda kana kushoma pane latitude 40ºN uye 50ºW, uko mvura yaro inodziya uye ine munyu inoenderera mberi nenzira yavo kuchamhembe muNorth Atlantic yazvino, uye Norway ikozvino, uye kumaodzanyemba kuburikidza neCanary Islands ikozvino.
MuNorth Atlantic, mvura dzayo dzinosvika kuNorway neGreenland, kwadzinotonhora nekukurumidza nekuda kwekuswedera padanda. Mukudaro, vanove vanonyanyisa nekuda kwekuwanda kwavo kwemunyu, saka vanonyura nekuda kwesimba regiravhiti. Saka, fudza iyo thermohaline kutenderera zvinoyerera zvakadzika.
Ndeapi maitiro ayo?
Iine avhareji yehupamhi hwe80 kusvika ku150km uye kudzika kuri pakati pe800 ne1200m, mvura yayo inofamba nekumhanya kwakanyanya kwe 2 metres pasekondi sezvo iri kusvika munzvimbo dzisina kudzika. Iyo tembiricha inosiyanawo zvakanyanya mumiganhu nekuda kwekusangana nemvura inotonhora yekuchamhembe uye nemvura inodziya yekumaodzanyemba. Nekudaro, semuenzaniso, munzvimbo yakamanikana inopatsanura Florida kubva kuBahamas neCuba, tembiricha yepasi inofadza 25ºC, nepo muNorway, muBaltic Sea, ingangoita 9ºC.
Kubva kwayakatangira kusvika kudunhu reGreat Banks, ino ndiyo yazvino ine yakadzika bhuruu ruvara uye yakakwira munyu, asi inorasikirwa nayo painosanganiswa neNorth Atlantic yazvino. Ehezve, kuyerera kwayo kunoshamisa: padyo neIreland ndizvo 150 mamirioni m3 / s, iyo inoita kuti ive inonakidza kwazvo yemvura yegungwa pasi rese. Kutipa zano, kuyerera kunotakurwa nenzizi dzese dzinoyerera dzichiyerera dzenzizi dzese dzinoyerera dzichipinda muAtlantic dzinowedzera kusvika ku0.6 * 106 m3 / s.
Kana ikangosvika muEurope, inopatsanurwa kuita hova diki diki dzinoyerera pakati pegumi nemakumi maviri emamirimita pa sekondi.
Ndeapi maRingi?
Mufananidzo - NASA Goddard Space Flight Center
Iyi ndiyo yazvino yekuti kana yapatsanuka kubva kumahombekombe eAmerica inotanga kuyerera zvakadzama. Nekudaro, mvura inotonhorera inoparadzaniswa nemvura yeGungwa reSargasso, uye inowanzo gadzira mamanders ayo anokwanisa kusvika kuma350km. Kana vazvivharira vodaidzwa Zvindori, iyo inosvika pakapakati pakati pe50 ne200km uye inogona kugara kubva pamwedzi kusvika kumakore akati wandei. Vanofamba makiromita mashoma pazuva, vakananga kumadokero kana akananga kuEquator.
Izvo zvinowanzoitika zviitiko mumiganhu yemvura ine tembiricha dzakasiyana. Ivo govera kupisa uye munyu kubva kune imwe nzvimbo kuenda pane imwe. Zvakare, zvinofanirwa kutaurwa kuti kune maRings ane anotonhora emvura macores, uye maRings ane anopisa emvura macores. Iwo aimboenda kumaodzanyemba uye akadzika (pakati pe4000 ne5000 metres), ane yakareba "hupenyu" nguva uye yakakura dhayamita.
Nei Gulf Stream yakakosha kwazvo kuEurope?
Pasina Gulf Stream, Europe ingadai isina kusiyana zvakanyanya neNorth Pole. Ehe, zvaisazove kutonhora senge iriko, asi zvingave zvichinyatso kuoneka pane ma thermometer. Sei? Nekuti huwandu hwesimba rinopisa iro rino razvino rinotakura rakaenzana nehukuru hwayo, ndiko kuti, kana mvura yakapetwa kane chiuru kupfuura mweya, Inotakura zvakapetwa chiuru zvakapfuura mwero wakaenzana wemhepo. Tichifunga nezvekuti ino yazvino inotakura inodziya mvura kubva kunzvimbo dzinopisa dzemvura dzeFlorida kuenda kuOld Continent, vane basa rakakosha kwazvo mumamiriro ekunze eEuropean.
Uye ndezvekuti painosvika Europe, mvura inodziya inosangana nemhepo inotonhora. Musiyano uyu mumatembiricha egungwa chairo nemuchadenga ndizvo zvinosarudzira mamiriro ekunze kwenzvimbo kwainopfuura, kwete muEurope chete, asi munyika kubva mhepo inotonhora inouya ichibva kuWest yeNorway, painenge ichiyerera pane ino inopisa uye inobatsira kudzikamisa tembiricha yepasi.
Ndinovimba wakadzidza zvakawanda nezve Gulf Stream 🙂.
