Ukufudumala kwembulunga yonke kanye nokushintsha kwesimo sezulu kuya kuba namandla unyaka nonyaka. Ukwenyuka kwezinga lokushisa emhlabeni jikelele, amagagasi okushisa kanye nokwenyuka kwezinga lokushisa lolwandle kuyimiphumela ehlushwa umfutho okhulayo kanye nemvamisa. Amazinga okushisa angaphezulu kolwandle ayaqhubeka ehla esilinganisweni salesi sikhathi sonyaka. Ezinye izingxenye ze I-Western Mediterranean isivele ingu-5ºC ngaphezu kokujwayelekile futhi izibikezelo azikabuyeli kwesejwayelekile.
Kulesi sihloko sizokutshela ukuthi yini imiphumela yamazinga okushisa aphezulu oLwandle iMedithera nokuthi kungani ekhuphuka kakhulu.
ukufudumala kwezilwandle
Igagasi lokushisa elihlasele iNhlonhlo ezikhathini zamuva nje lingesinye sezindimbane zomoya ezifudumala kakhulu ebezilokhu zidlula kulesi sifunda. Ezinye zalezi zindimbane zomoya zakhiwe yi ukushisa okukhulu kwelanga kanye nokuntuleka kokunyakaza komoya, kuyilapho abanye bevela ezindaweni ezishisayo, njengeSahara. Lesi samba esikhulu somoya ofudumele sephule amarekhodi amaningi okushisa ezindaweni ezahlukene zeNhlonhlo, futhi sephule namarekhodi amasha eziteshini ezingaphezulu.
Ngaphambi kokuba lomoya ofudumele ungene, sadlula kwezinye izindimbane zomoya ezixakile, njengangoJune, negagasi lokushisa, futhi ngo-May, sihamba nemisinga enamandla efudumele. I-Mediterranean, i-Bay of Biscay kanye nezingxenye zoLwandlekazi i-Atlantic nazo zihlangabezana nezimo ezingezinhle zokushisa. Nakuba kungashisi njengesibonelo sokugcina, lawa mazinga okushisa asangavamile kakhulu ngesikhathi sonyaka futhi abaluleke kakhulu. Izindawo zaseWestern Mediterranean amazinga okushisa amanje angu-5 degrees ngaphezu kokuvamile engxenyeni yesibili kaJulayi.
Imiphumela yamazinga okushisa aphezulu oLwandle iMedithera
ULwandle iMedithera belubhekene namazinga okushisa aphezulu, kanye nokunye okungahambi kahle. Lezi ngeke zishintshe esikhathini esizayo esiseduze, ngokusekelwe ekuqondeni kwethu kwamanje. Ukushisa kuzohlala lapho okungenani isonto elizayo, ngokusho kwesibikezelo se-ECMWF. Isizathu siwukuthi kuzoba nokunyakaza okuncane kakhulu komoya ofudumele kanye nomswakama uzoba phansi phezulu, kukhawule ukupholisa okuhwamukayo. Ukuthi iMedithera inamazinga okushisa aphezulu kangaka akuyona into esike sayibona ngaphambili, futhi imiphumela izobonakala esikhathini esizayo esiseduze. Eminye yale miphumela isivele iqala ukubonakala.
Ezindaweni zolwandle eduze nogu noma eziQhingini zaseBalearic kungaba khona ukushisa okuphansi kakhulu. Lokhu kungaba nomthelela kwiphethini yomoya ohelezayo, kukhuphule umswakama womoya eduze nolwandle, futhi kube nomthelela omkhulu emiphakathini yasogwini. Futhi amandla angakhiqizwa ulwandle kulelo zinga lokushisa awavamile ukunganakwa. Ubuso bamanzi bungaphezu kuka-28 degrees Celsius nongqimba oluwugqinsi olunjalo, ulwandle lungabamba amasistimu wokuguquguquka anamandla, adale amaphethini anzima eziphepho.
Lezi zimo zingadala iziphepho ezinamandla ezindaweni ezisogwini. Ngokuvamile lawa mazinga okushisa avame ukuqala ngokufudumala kwezilwandle. Nokho, iqiniso lokuthi uLwandle iMedithera lunamazinga okushisa aphezulu akusho ukuthi lezi zinhlobo zeziphepho zizokwenzeka. I-troposphere kufanele ihlangabezane nazo zonke izimo ezidingekayo ukuze lezi zenzakalo zenzeke.
Amazinga okushisa angavamile kulezi zikhathi
Ulwandle iMedithera lunamazinga okushisa afana kakhulu nawaseCaribbean. Ngokungafani nalokho okuvamile ukwenzeka lapho ungeniswa emanzini olwandle, manje ayinikezi nhlobo uhlobo lombono nhlobo. Kweminye imikhakha ye-Balearic Sea izinga lokushisa Icishe ibe ngama-degree angama-30, kanti kwamanye amabhishi njengalawo aseningizimu yeMedithera icishe ibe ngu-28 degrees. Ngokujwayelekile lamazinga okushisa aphezulu afinyelelwa enyangeni ka-August noma ekuqaleni kuka-September lapho konke ukushisa sekunqwabelene ehlobo. Kodwa-ke, ukuba khona kwamazinga okushisa aphezulu, imimoya ebuthakathaka kanye nezinga eliphezulu lokukhanya kwelanga kule nyanga kubangele ukuthi sifinyelele amazinga okushisa aphezulu kangaka.
Ngaphandle uma kukhona uhlobo oluthile lweziqephu zokungaqini komkhathi, umoya wasentshonalanga noma into enamandla kakhulu engabangela amanzi ukuba avuselelwe futhi esikhundleni sawo kufakwe amanzi abandayo asuka phansi, lawa mazinga okushisa asenayo indawo eyanele yokukhuphuka. Sesivele siqaphela imiphumela eqondile yamazinga okushisa aphezulu oLwandle iMedithera. Imimoya yomoya ibuthaka futhi ayiqabuki. Lokhu kungenxa yokuthi zilayishwa ukushisa nomswakama futhi zikhulisa kakhulu umuzwa wokuphoxeka.
Phakathi kwamazinga okushisa aphezulu, umphumela wesiqhingi sokushisa sasemadolobheni nolwandle olufudumele, kwamanye amadolobha asogwini cishe awehli ngaphansi kwama-degree angu-20 ebusuku. Lokhu kubangela ubusuku obuncishanayo obunomswakama ophezulu kakhulu kanye namazinga okushisa aphakathi kuka-23-25° degrees. Akunakwenzeka ukwazi ukuthi konke lokhu kuzoguqulela izimvula ezinamandla ngesikhathi sekwindla. Siyazi kakade ukuthi ulwandle ngokwalo alukwazi ukuletha izimvula ezinamandla, njengoba kudingeka izimo ezikahle kulo.
Izimvula ezinkulu
Siyazi ukuthi ulwandle olufudumele luzokwengeza ikhalenda lezimvula ezinamandla, into evele ibonakale eminyakeni yamuva nje nezimo zezulu ezimbi kakhulu ebusika noma entwasahlobo. Leli qiniso seliyinto okufanele sizivumelanise nayo. Ukuguquka kwesimo sezulu kuya kugqama kakhulu futhi imiphumela yako inamandla kakhulu. Khumbula ukuthi ohulumeni bazama ukuthola izindlela zokuzivumelanisa noshintsho kunokuba baluvimbele. Kuyaziwa ukuthi cishe sekwephuze kakhulu ukunqanda imiphumela yokushintsha kwesimo sezulu. Ngisho noma singamisa konke ukukhishwa kwe-carbon dioxide namanye amagesi abamba ukushisa emkhathini manje, Imiphumela yokushintsha kwesimo sezulu izoqhubeka nokuthinta iplanethi.
Njengoba ubona, izikhathi ezishisayo zisilindile esingakwazi ukuzivumelanisa nazo nokuthi zingaba namiphi imiphumela, hhayi nje kuphela ezingeni lendawo ezungezile, kodwa nasezingeni lezenhlalo nelezempilo. Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nemiphumela yamazinga okushisa aphezulu oLwandle iMedithera.
