Ukwanda kokukhishwa kwe-CO2 kuzothena amandla imvula yaseNyakatho Melika

Izwe elinemvula

Siphila ezweni lapho, yize kungabonakala kungakholeki, okwenzeka lapha kungaba nemiphumela kwenye ingxenye yomhlaba. Ngokuqondene nesimo sezulu, besivele sikhulume ku-a isihloko ukuthi inani elikhulu lamanzi akhiqizwa amahlathi emvula alawula amazinga okushisa emhlabeni jikelele.

Manje, ucwaningo olushicilelwe ephephabhukwini i-Nature Climate Change, seluthole ukuthi, ngokuqhubeka nokukhipha isikhutha emkhathini, isiphepho saseNyakatho Melika singancipha. Uma bekwenza, imiphumela ingaba mikhulu.

Yini imonono?

Amafu emvula

Ukuze siqonde ubucayi bendaba, ake sichaze ukuthi ziyini izimvula. Imonsoon umoya wonyaka okhiqizwa ukufuduka kwebhande lemvula elishisayo, osuka enyakatho yeTropic of Cancer uye eningizimu yeTropic of Capricorn ngokuhamba konyaka. Leli bhande lithwala izimvula eningizimu yezwe kusukela ngo-Okthoba kuya kuMashi, nasenyakatho Nenkabazwe kusukela ngo-Ephreli kuya kuSepthemba.

Ngenkathi kwenye ingxenye lina kakhulu, liholele kwizikhukhula ezimbi kakhulu, kokunye, isikhathi sonyaka owomile sikhona.

Ikhiqizwa kanjani?

Ifu phezu kolwandle

Zibangelwa ukuthi umhlaba uyaphola futhi ushise ngokushesha kunamanzi. Kukhona imvula yasehlobo, nemvula yasekwindla. Owokuqala wakhiwa ngenxa yokuthi umhlaba ufinyelela izinga lokushisa eliphakeme kunalelo lolwandle, ukuze umoya ukhuphuke ubheke emkhathini obangela isiphepho noma indawo yengcindezi ephansi. Umoya uvunguza usuka ezindaweni ezinengcindezi ephezulu uye ezindaweni ezinengcindezi ephansi ukuzama ukulinganisa zombili izingcindezi, ngaleyo ndlela udale umoya onamandla ovela olwandle. Ekugcineni, imvula iba khona ngenxa yokuphakama nokupholisa komoya ezintabeni.

Ngesikhathi sokuwa nobusika umhlaba uphola ngokushesha okukhulu, kepha ulwandle luthatha isikhathi eside ukwenza njalo, ngakho-ke izinga lokushisa lihlala liphezulu. Ngakho-ke, umoya uyakhuphuka ubangele indawo yengcindezi ephansi olwandle, bese kuvunguza umoya osuka emhlabeni uye olwandle. Njengoba umehluko emazingeni okushisa phakathi kokunye nomunye ungaphansi kakhulu kunasehlobo, umoya ophephuka kusuka ku-anticyclone uye esivunguvungwini awuhlali njalo.

Kungani isivunguvungu saseNyakatho Melika singase sibe buthakathaka?

I-Carbon dioxide

AmaMonsoon abucayi kakhulu kumagesi abamba ukushisa, ngokusho kwababhali besayensi be ukutadisha USalvatore Pascale, uWilliam R. Boos nethimba labo. Besebenzisa imodeli yezulu yomhlaba, bakutholile lokho Uma ukukhishwa kwe-carbon dioxide kuphindwe kabili, imvula yaseNyakatho Melika ibingancipha, ikakhulukazi eningizimu-ntshonalanga ye-United States. Kungani?

Ukusimama komkhathi, ngakho-ke, ukuhlangana okuncane okubangelwe ukushisa okufanayo kobuso bolwandle kubonakala kuyimbangela yokwehla kwezulu.

Ukuze, kuzothathwa izinyathelo zokuzivumelanisa nezimo futhi, ngaphezu kwakho konke, ukusebenzisa kangcono imithombo yamanzi.
