Iyo Totten Glacier ndiyo hombe kumabvazuva kweAntarctica uye iyo yakanyungudika iri kukurumidza nekuda kwekuwedzera kwemhepo muSouth Ocean. Nekudziya kwepasirese, iyo polar ice cap iri kunyungudika pamwero unowedzera nekukasira uye kana tikawedzera kune izvi mhepo dzinovatakura kuenda kumvura inodziya, nyoro yavo ichaitika nekukurumidza.
Iwe unoda kuziva mamiriro eiyo Totten glacier?
Totten glacier inonyunguduka nekukurumidza
IAustralia Antarctic Chirongwa chiri kuenderera mberi ichitarisa mamiriro eAntarctic glaciers. Iyo Totten Glacier ndiyo hombe kumabvazuva kweAntarctica uye kunyungudika kwayo kuri kuramba kuchizivikanwa, nekuda kwe mhepo dziri kuvhuvhuta zvikuru uye iri kusverera yakanangana nemvura inodziya yeAntarctic mhenderekedzo yegungwa iyo inopinda pasi pechikamu chinoyangarara chechando.
Kuenderera mberi kwekupinda kwemvura inodziya muchikamu chinoyangarara chechando inoita kuti inyunguduke nekukurumidza. Iyi mhedziso yakavakirwa pamubatanidzwa wesataneti mifananidzo, dhata dhata, uye kuongororwa kwenzvimbo dzemakungwa. Zvinonyatso kuoneka kuti chikamu chepazasi chiri kunyungudika nekukurumidza uye nekumhanyisa kufamba kwechando kuenda kugungwa.
“Basa redu rinopa humbowo hwekubatana kwemichina mu kupisa kupisa kubva mumhepo yakapfuura nemugungwa kusvika muchando, "akadaro mumwe wevaongorori, David Gwyther, anobva kuYunivhesiti yeTasmania, muchirevo.
Nekuda kwekushanduka kwemamiriro ekunze, kumhanyisa kwemhepo kunochinja muSouth Ocean uye izvi zvinofungidzirwa kuti zvichawedzera nekuwedzera, nokudaro, girazi reTotten richanyungudika nekukurumidza, zvichikonzera kusimuka kwepasirese pagungwa.
Mhepo yakasimba uye inodziya mvura
Izvo zvinhu zvinokonzeresa kunyungudika kwemazaya echando imhepo uye tembiricha yemvura. Munguva iyo mhepo inenge yakasimba, iyo yemvura yepamusoro inofamba ichienda uye inotsiviwa nemvura yakadzika uye inodziya, kuitira kuti painobata mazaya echando, inomhanyisa kunyungudika kwavo.
Iyo glacier inodhonzera 538.000 mativi emakiromita kumabvazuva kweAntarctica uye anorasa matani emamirioni 70.000 echando gore rega, maererano neAustralia Antarctic Division katsamba.
