Kunethiwekhi yemisinga yomoya emhlabeni wonke, kunezinhlobo ezahlukahlukene zemimoya evunguza kakhulu endaweni futhi ngokuqhubekayo noma kaningi, kuya ngezimo zemvelo. Kulokhu, ukusakazwa kwemimoya evunguza endaweni yase-Argentina kunqunywa ingcindezi ephansi noma isikhungo se-cyclonic kanye nama-anticyclone amabili noma izikhungo ezinengcindezi ephezulu. Lokhu kubangela kunemimoya emithathu yasendaweni evunguza e-Argentina: i-El Pampero, i-El Zonda neLa Sudestada. Ngabe ufuna ukwazi kabanzi ngale mimoya?
Ukusakazwa kwemimoya yendawo
Imimoya yendawo yase-Argentina ilandela amaphethini asungulwe yi-South Atlantic Anticyclone kanye ne-South Pacific Anticyclone. Okokuqala, inethonya layo elikhulu enyakatho yoMfula iColorado. Le anticyclone idala ukuthi imimoya iwele i-Argentina isuka eSouth Atlantic, iwele iBrazil. Imvamisa, imimoya ehambisana nalokhu ifudumele futhi inomswakama, edala imvula eningi enyakatho-mpumalanga yezwe futhi inciphe njengoba isondela ebangeni lezintaba.
I-anticyclone yesibili, eyaseNingizimu Pacific, ihlose ukuthonya isifunda sasePatagonia. Le mimoya nayo igcwele umswakama futhi ivela eSouth Pacific. Lokhu kudala imvula eningi phezu kwePatagonian Andes. Ngaphezu kwalokho, le mimoya iba nomphumela wesibili: isebenze njengomgoqo we-condensation, okwenza ukuthi yonke eminye imimoya ifike icishe yome emathafeni asePatagonia.
E-Argentina kunezici ezinjenge-latitude, impumuzo nokujikeleza komoya okungenelela ezicini zezinhlobo zezulu. Yile mimoya yendawo ethinta isimo sezulu zezindawo ezahlukahlukene zensimu yase-Argentina. Imimoya emithathu yasendaweni evunguza e-Argentina yiPampero, i-El Zonda neLa Sudestada.
IPampero
Imvelaphi yaleli gama ibuyela emuva ekufikeni kokuqala kwabaseSpain bokuqala eRío de la Plata, abashaywa ngumoya onamandla ovela emkhakheni oseningizimu nentshonalanga owaletha umoya omile nomile. Amakholoni asendulo abona izinguquko zezulu kule ndawo zihluke kakhulu kulezo ezenzeka eYurophu.
Ipampero inemvelaphi yayo ngenxa esikhungweni sokucindezela okuphansi esemathafeni asenkabeni nasenyakatho-ntshonalanga ye-Argentina. Lesi sikhungo sezingcindezi eziphansi sinamandla kakhulu ehlobo futhi singakhanga imimoya ye-anticyclone yaseNingizimu Pacific.
Lapho isikhungo sezingcindezi eziphansi senziwa, ngokwesibonelo lapho amazinga okushisa enza inani elikhulu lomoya likhuphuke ukuphakama, izindimbane zomoya ezizungezile zama ukufaka esikhundleni indawo eshiywe nenani elincane lomoya. Ngakho-ke, yonke imimoya esendaweni yeSouth Pacific anticyclone iya enkabeni yengcindezi ephansi.
Njengoba kushiwo ngaphambili, le mimoya yase-South Pacific anticyclone iyabanda futhi yomile, ngoba isebenza njengesithiyo futhi ilahlekelwa umswakama. Imvamisa ishaya ngezinsuku zasehlobo futhi izinga lokushisa nomswakama walo kuyanda ngenxa yokufika kwemimoya yezohwebo.
Ngakho-ke, uPampero uthuthuka ngokushesha eLa Pampa, esungula phambi kwesiphepho endaweni yokuxhumana phakathi kwalezi zixuku ezimbili, ngoba banokuhluka ngokomswakama nokushisa.
IPampero ubukhulu obubandayo nobomile, kanti enye ifudumele futhi inomswakama, ivela emimoyeni yezohwebo. Lokhu kuxhumana phakathi kwenqwaba yamakhaza omile nofudumele kubangela iziphepho zikagesi, izimvula eziningi, noma kaningi ngesichotho futhi kuhambisana nokwehla okungazelelwe kokushisa. Lapho umphambili unyamalala ngemuva kwesikhashana, kubuye kuphole futhi kome futhi.
Lapho umoya wePampero ulahlekelwa umswakama wawo lapho unqamula uhla lwezintaba, kubanda futhi kome kuphela, kubizwa ngokuthi yiPampero seco. Lapho kubangela imvula engaphambili eshiwo ngaphambili, ibizwa ngokuthi yi-humid Pampero. Uma umoya waseningizimu-ntshonalanga ungakhi imvula futhi uveza izivunguvungu zomhlaba, ubizwa ngokuthi yi-Dirty Pampero.
Isibikezelo sePampero
Ukuthola ukuthi iPampero ishaya nini, izazi zezulu zibheka uhlelo lokucindezela okuphezulu oluseningizimu yeBrazil. Lesi sikhungo sengcindezi ephezulu siveza imimoya evunguza phezu kweRío de la Plata nayo yonke inyakatho nendawo yezwe. Njengoba le mimoya ivunguza izinga lokushisa nomswakama kuyanda njalo nengcindezi iphezulu.
Umoya ungahlala phakathi kwezinsuku ezimbili noma ezintathu njengoba ubukhulu bomoya obandayo nokomile obuthatha yonke iPatagonia busondela. Lapho lesi sikhathi sidlula, ingcindezi iqala ukwehla kancane kancane, kanti umswakama nokushisa kugcina amanani aphezulu kakhulu). Ngaphansi kwalezi zimo, ukwehla kwengcindezi kuyabonakala (kufika ku-1.5 hPcal), bese ngokuzumayo kubhekwe ngaseningizimu noma ngaseningizimu-ntshonalanga umugqa omnyama wamafu eziqhubekela phambili zibheke eRío de Plata. Lawa mafu amaka ngaphambili kwenyakatho-mpumalanga ebandayo ehamba ngamafindo angama-20-30.
Isudestada
I-sudestada ingenye uhlobo lomoya wendawo ohlasela e-Argentina. Imvelaphi yayo ingenxa yokuvela kwesikhungo sengcindezi esiphansi ogwini lwasePampean. Lapho lesi sikhungo sezingcindezi eziphansi sakhiwa, iheha yonke imimoya ebisakazeka endaweni yengcindezi ephezulu eSouth Pacific.
Leli seli elisendleleni yalo liwela iPatagonia futhi lapho libuyela e-Atlantic liphinde lifake umswakama, okhishwa lapho liphinda lingena ezwenikazi. Lapho lezi zimvula zenzeka, ngokuvamile zihlala kancane izinsuku ezintathu kuya kwezinhlanu. Azivamisile ukudlula kuma-drizzles ngendlela eqhubekayo phakathi naleso sikhathi esifushane.
Izinyanga lapho lolu hlobo lomoya luvame kakhulu ku izinyanga zika-Ephreli no-Okthoba.
AbakwaZonda
Lokhu kungomunye umoya wasendaweni ovunguza lapho emkhakheni osempumalanga wamagquma aseLa Rioja, eSan Juan naseMendoza, kusungulwa isikhungo sengcindezi ephansi esiheha imimoya yeSouth Pacific Anticyclone. Ukusebenza kwayo kufana neSudestada.
Uma isiqalile, ikhuphuka ngokuqhubekayo njengoba ifinyelela ebangeni lezintaba futhi izinga lokushisa layo liyancipha. Lokhu kubangela ukujiya komswakama, kwakheke amafu aqhamukayo imvula ngesimo semvula neqhwa. Ngemuva kwalokho, ngejubane elingadlula amakhilomitha angama-50 ngehora, umoya wehlela emthambekeni osempumalanga, ubangele ukushisa kwawo kukhuphuke ngenxa yokushayisana kwama-molecule omoya omelene njengoba ecindezelwa ngesikhathi sokuwa. Ngakho ekugcineni ufinyelela ezinyaweni zentaba njenge umoya ofudumele owomile, ngamazinga okushisa asondele ku-40 ° C.
Yize lo moya ubacasula kakhulu abantu, kuqinisekisa ukutholakala kwamanzi okuqhubekayo wokunisela nokunye okusetshenziswayo njengokuphakelwa.
Njengoba ukwazi ukubona, i-Argentina ibuswa yimimoya emithathu yasendaweni, enezici ezibenza bahluke futhi babhekane nesimo sezulu sezwe.
Nginibhalela ngenhloso yokuthola imininingwane ngemithombo eceliwe ukubonisa imimoya yendawo. Lolu lwazi luzosetshenziselwa ukwenza iphrojekthi yocwaningo ezokwenziwa e-Escuela Normal Superior uDkt Luis Cèsar Ingold. Ngiyethemba ngobuqotho impendulo yakho. ngiyabonga
Umoya okhona ehlobo lethu elifudumele eParaná, i-ER, ungabonakala uyiPampero (yize ngingaqiniseki ngempela). Ukuqondiswa kwayo kusuka phakathi eningizimu naseningizimu-ntshonalanga kungafaneleka ukuklama i-aeration yemvelo yendlu yesihlanu esemaphethelweni edolobha. Ngamanye amagama, ukuvumela umoya ukuthi udlule kuyo yonke indlu ukusiza ukunciphisa umuzwa oshisayo wasendlini.
Uhlelo lukaZonda alulungile. Umoya uyanda lapho ufuthelana futhi ucindezela lapho selehlile. Ku-schema lolu lwazi lubuyiselwa emuva.
Kuhle ekuseni
I-pampero kanye ne-sudestada akuzona imimoya, kodwa izimo zezulu ezenzeka kulezi zindawo.
Okwenzekayo ukuthi ngesikhathi sesimo se-Pampero esingavamile umoya okhona yi-SW. Kodwa akuwona wonke ama-SW angama-pampero.
Okufanayo esimweni esingavamile kakhulu sase-Sudestada (izikhathi ezimbalwa kuphela ngonyaka) umoya ungu-SE, kodwa akuyona yonke i-SE eseningizimu-mpumalanga.
