Ilanga. Umthombo wamandla wokuphila eMhlabeni. Yize iqhelelene ngamakhilomitha ayizigidi eziyi-149,6, inomthelela omangalisayo eplanethi yethu encane. Ngaphandle kwayo, bekungeke kube nje ngaphandle kwebhaluni elibandayo, elinamadwala elihamba ngomkhathi.
Kodwa, Ilanga lisithinta kanjani isimo sezulu? Buyini ubudlelwane phakathi kwenkanyezi nomhlaba?
Iplanethi esiphila kuyo inomoya ominyene, kangangoba ingxenye enhle yamandla elanga efinyelela kithi ilahleka lapho sidlula kuyo. Imisebe eyingozi kakhulu, njengemisebe ye-gamma, i-X nengxenye enhle yemisebe ye-ultraviolet, ayifinyeleli kwi-biosphere ngenxa yalolu ungqimba oluzungeze uMhlaba.
Asitholi inani elilinganayo lamandla elanga kuzo zonke izingxenye zomhlaba noma kuzo zonke izinsuku zonyaka. Ngokuya ngokuthambekela kwe-eksisi yeplanethi, kanye nobukhulu besibhakabhaka endaweni ethile, imisebe yelanga ingafika icishe ibe buthakathaka, futhi iqonde ngqo.. Lokhu kuchaza ukuthi kungani ezigxotsheni, izindawo ezikude kakhulu nelanga nalapho umoya ushubile kakhulu, i ithempelesha ingahle iye ku -80ºC noma ngaphezulu, noma ezingwadule ezishisayo zikhuphukela ku-60ºC. Imisebe yelanga eplanethini enguMhlaba iyisici esiyinhloko kulokhu kuhlukahluka kwezinga lokushisa, njengoba kuchazwe kabanzi esihlokweni esithi imisebe yelanga kanye nomthelela wayo esimweni sezulu.
Lokhu kuhlukahluka kubangela ushintsho lwengcindezi emkhathini, kwakheka imisinga yomoya ehlangana nemisinga yolwandle futhi ikhiqize izinto ezinjengeziphepho, izishingishane, njll. Ngaphezu kwalokho, imiphumela ehlobene nemisinga yolwandle i-cumulonimbus kanye nezinye izinhlobo zamafu ezithonya ukuziphatha kwesimo sezulu.
Imijikelezo yelanga nesimo sezulu
Isithombe - Met Office
Ilanga linemijikelezo yeminyaka eyi-11, lapho amabala amaningi noma amancane angabonwa khona. Kuyaziwa ukuthi izindawo ezimbalwa ezikhona, kuzoba kubanda kakhulu emhlabeni. Ngesikhathi se-Little Age Age esukela ekuqaleni kwekhulu le-XNUMX kuya maphakathi nekhulu le-XNUMX, umsebenzi welanga oboniswe emachosheni elanga wawuphansi kakhulu. Lesi sikhathi somsebenzi ophansi, esaziwa ngokuthi yi-Maunder Minimum, esiqondane nesikhathi lapho amazinga okushisa ephansi kakhulu, sithatha ukuthi amabala elanga athonya isimo sezulu. Ngenxa yalesi sizathu, akumangazi ukucabangela indlela ama-aerosols athonya ngayo isimo sezulu somhlaba wonke, njengoba kuchazwe esihlokweni esithi. amahlumela e-aerosol, okubuye kube nomthelela wokubonga emisebeni yelanga.
Ngabe sibheke e-Ice Age?
Kunokungabaza okuningi ngakho. Njengamanje, sicwiliswa esikhathini lapho ilanga linciphisa khona ukusebenza kwalo, futhi ngokusho kwe- a isifundo esishicilelwe kumagazini iSayensi kukhona cishe amathuba ayi-15-20% weMaunder Minimum entsha eyenzekayo.
Ngaleso sizathu, izinga lokushisa lomhlaba wonke lizokwehla ngo-0,1ºC, njengoba iYurophu, i-Asia neNyakatho Melika kuyizindawo lapho kuzobonakala khona kakhulu, ngokwehla phakathi kuka-0,4 no-0,8ºC. Lokhu kungaba nomthelela othile ekufudumaleni komhlaba, nakuba bekungeke kwanele ukukumisa. Ngalo mqondo, kuye kwashiwo okokuqala ukuthi umsebenzi welanga uthinta ukushintsha kwesimo sezulu kanye nobudlelwano bayo nomsuka wokufudumala kwembulunga yonke.
