La Antarctica Inzvimbo iyo migumisiro yekuchinja kwemamiriro ekunze iri kuwedzera kuoneka. Iye nyungudika Ndiyo imwe yematambudziko anonyanya kunetseka akatarisana nekondinendi ino, kwete kungotyisidzira mararamiro ezvipenyu zvinogara mairi, asi zvakare kuisa njodzi yakakomba kunharaunda dzemahombekombe kutenderera pasirese nekuda kwe Kukwira kwemwero wegungwa. Izvi zvinosimbisa kukosha kwekunzwisisa zviitiko zvine hukama, senge mhedzisiro yekunyungudutsa ice muAntarctica, uye mukana wekuti Antarctica icharasikirwa ne25% pasi peaizi pakupera kwezana ramakore..
Ongororo ichangoburwa yakaitwa nevanoongorora pa ARC Center yekunakisa yeClimate System Sainzi kwaratidza kuti mhepo dziri mu East Antarctica Vanogona kukonzera mhirizhonga mugungwa inopararira kuburikidza nechiitiko chinozivikanwa se Kelvin anozunguza, kirasi yemafungu egungwa.
ari Kelvin anozunguza Dzinoumba munyanza uye, padzinosangana nepamusoro pemvura yeEastern Antarctic Peninsula, dzinosaidzira mvura inodziya ichienda kumasherufu makuru echando ari pamhenderekedzo. Izvi zvine hukama zvakanyanya nekukasira kunyungudika muWestern Antarctic chikamu, sezvo, padhuze nesherufu yekondinendi yedunhu rino, the Antarctic Circumpolar Warm Current inopa nguva dzose mvura inopisa iyo inowedzera dambudziko racho. Kuti uwane maonero akazara, zvinokurudzirwa kuverenga nezvazvo kunyunguduka kwematanda y Nyaya yekunyunguduka kweTotten Glacier.
Mhedzisiro yaKelvin Waves paIce Melting
Kana masaisai aya asangana ne marine topography, bvisa mvura yakawanda inodziya ichienda kumasherufu echando, izvo zvinobatsira ku kukurumidza kunyunguduka zvezvivakwa izvi. Iri harisi dambudziko riri roga, sezvo shanduko yekushisa kwemvura munzvimbo ino inogona kukonzera inoparadza mhedzisiro kwete chete paiyo Antarctica, asi mumamiriro ekunze enyika yose. Iye arctic kunyungudika Iyo ine zvakare yakakosha mhedzisiro, pamwe neiyo kukwira kwekushisa munharaunda yeAntarctic.
ari kuchinja kwemhepo dzomugungwa mudunhu rino zvine chekuita nekushanduka kwemamiriro ekunze, sezvo, sezvo tembiricha yepasi rose inowedzera, mhepo dzekumavirira dzakafanana nemadutu mumhepo. Southern Ocean vanopisawo. Izvi zvinogadzirisa mafambiro emhepo anowanikwa pedyo ne Antarctica, kuva chiitiko chinokanganisa zvakare tundras inoshanda semaamplifiers ekuchinja kwemamiriro ekunze.
Sea Level Rise Projections
Kunyura mu Antarctica Idambudziko remangwana repasi. Kufungidzira kunoratidza kuti panosvika gore ra2100, Mwero wegungwa unogona kukwira kupfuura mita, uye panosvika gore ra2500, anopfuura 15 metres, kana maitiro ezvino ekubuda achienderera mberi. magasi anodziya. Chiitiko ichi hachingokanganisa Antarctica chete, asi chinozokonzeresa nhevedzano yematambudziko kunharaunda dzemahombekombe pasirese, sezvakatsanangurwa muchinyorwa che. kukwira kwekushisa muAntarctica and the zvinogona kukanganisa kuputika kwemakomo munharaunda.
Vatsvagiri vanosimbirira pakuda kutora matanho nekukasika kuderedza kudziya kwepasi. Nekudzoreredza kuburitsa, pane tariro yekuti nzira dzemadutu dzekumaodzanyemba enda kuchamhembe, izvo zvinogona kubatsira kunonotsa kunyunguduka kweaizi. West Antarctica. Uyezve, izvi zvingaderedza kudziya kwemakungwa, zvichibvumira mamwe mahombe echando kuti agadzikane, uye ane hukama zvakananga Larsen C thaw ichikonzera kusagadzikana munharaunda.
Kelvin Waves uye Kwavanobva
ari Kelvin anozunguza Izvo zvinhu zvakasikwa izvo zvakadzidzwa uye zvakanyorwa kweanopfuura zana remakore. Aya masaisai emugungwa anofamba achitevedza mahombekombe, achitakura mvura inodziya kubva munyanza kuenda kunzvimbo dzinotonhorera. Ichi chiitiko chakaoma, sezvo zvinosanganisira zvinhu zvakawanda zvine chekuita neiyo ocean dynamics and the atmospheric physics. Chinyorwa chinobata chiitiko ichi zvakadzama ndeichi kuumbwa kwemadziva ebhuruu muAntarctica, pamwe chete nemigumisiro ye.
Somuenzaniso, kuchinja kwetembiricha yegungwa, mafambiro emhepo, uye mhepo yemhepo zvose zvinoita basa rinokosha mukuumbwa nokupararira kwemafungu eKelvin. Mhepo inodziya iyi inotangira kune rumwe rutivi rwe Antarctica, kupfuurisa 6000 makiromita kure, uye inogona kuve nemhedzisiro pamamiriro ekunze eAntarctic. Mukuwedzera, the rekodha yakaderera gungwa ice muAntarctica inoratidza kuti zviitiko izvi zvinodyidzana sei.
Tsvagiridzo yakaratidza kuti mhepo idzi dzinogona kukonzera kuwedzera kwekushisa kwemvura yegungwa kusvika 1 ° C pakadzika kwemasherufu echando, iyo ine zvirevo zvakakosha kuitira kugadzikana kwemasherufu echando enharaunda. Nyaya yakabatana uye inoshungurudza ndeye kukanganisa kwakashata kwekunyunguduka kwechando panyika.
Hukama neClimate Change
Kubatana pakati pe Kelvin anozunguza uye kuchinja kwemamiriro ekunze hakurambike. Sezvo vanhu vachiramba vachiburitsa huwandu hukuru hwemagasi egreenhouse, iwo kupisa kwepasi pose zvinova pachena. Iko kukurumidza mukunyunguduka kwe Antarctica chiratidzo chakajeka cheizvi, uye ongororo dzinoratidza kuti kunze kwekunge danho rekukurumidza rakatorwa kumisa kuburitswa, tarisiro yeramangwana inova isina kujeka. Kuti utarise zvakanyanya, zvakakosha kuziva iyo Antarctic inokanganisa mamiriro ekunze enyika.
Somuenzaniso, mumwe mushumo wenguva pfupi yapfuura unonyevera kuti kana nzira yazvino ikasachinjwa, tinogona kuona kukwira kwemvura yegungwa kunogona kudzinga mazana emamiriyoni evanhu kubva mumisha yavo panopera zana rino remakore. Uku kudanwa kwekumuka kune wese: isu tinofanirwa kuita izvozvi kuchengetedza pasi redu nemamiriro ekunze ayo. Iye chando chinonyunguduka muAntarctica Icho chiratidzo chekukurumidzira kwemamiriro edu ezvinhu.
Sezvo tembiricha dzichiramba dzichikwira, pane zvakare njodzi yekuti mamwe masherufu makuru echando achabva kure Antarctica. Zviitiko izvi, zvakaita sekudonha kwesherufu yeaizi yeLarsen C, zvinoratidza kuti kudziya kwepasi kungave nekukanganisa sei nharaunda yenharaunda. Kuputsika kunogona kuverengwa muzvinyorwa pamusoro kupunzika kwepuratifomu yeLarsen C uye hukama hwake naye Kunyunguduka kweAntarctic Ocean, iyo inogona kuwedzera kuumbwa kwegore.
Kudiwa Kwechiito
Tichifunga nezvezvinetswa izvi zvese, masayendisiti anosimbisa kukosha kwekushandisa mitemo inoshanda yekugadzirisa shanduko yemamiriro ekunze. Batanidza mafomu e kuderedza kubudiswa uye kusimudzira simba rinogonekazve matanho akakosha atinofanira kutora kuti tive nechokwadi cheramangwana rakagadzikana. The Tundras, semuenzaniso, yakakosha mune ino mamiriro..
Kusavimbika kwakatarisana neramangwana remamiriro ekunze epasi rose kuri pachena, asi kune nzira dzinogona kubatsira kuderedza kukanganiswa kwemamiriro ekunze Antarctica. Somuenzaniso, nzira dze geoengineering izvo zvinogona kubatsira kudzoreredza mamwe emhedzisiro yekudziya kwepasi.
