IPampero, iZonda kunye neSudestada

Kuthungelwano lwemisinga yomoya kwihlabathi liphela, kukho iintlobo ezahlukeneyo zomoya ovuthuza ngakumbi apha ekhaya ngokuqhubekayo okanye rhoqo ngakumbi, kuxhomekeke kwimeko yendalo esingqongileyo. Kule meko, ukujikeleza komoya ovuthuzayo kwingingqi yeArgentina kumiselwa ngoxinzelelo oluphantsi okanye iziko lecyclonic kunye neendawo ezimbini zokulwa neentsholongwane okanye amaziko oxinzelelo oluphezulu. Oku kubangela kukho imimoya emithathu yasekhaya evuthela eArgentina: El Pampero, El Zonda kunye neLa Sudestada. Ngaba uyafuna ukwazi ngakumbi ngale mimoya?

Ukujikeleza kwemimoya yendawo

Imimoya yendawo yaseArgentina ilandela iipateni ezisekwe yi-South Atlantic Anticyclone kunye ne-South Pacific Anticyclone. Eyokuqala, inefuthe layo elikhulu kumantla oMlambo iColorado. Le anticyclone ibangela ukuba imimoya iwele iArgentina isuka emazantsi eAtlantic, inqumle iBrazil. Ngokwesiqhelo, imimoya ehamba kunye nayo ifudumele kwaye ifumile, ebangela ubuninzi bemvula emantla mpuma welizwe kwaye yehle njengoko isondela kwintaba.

I-anticyclone yesibini, leyo ye-South Pacific, yenzelwe ukuba nefuthe kwingingqi yePatagonia. Le mimoya ikwathwele ukufuma kwaye ivela eMzantsi Pacific. Oku kubangela imvula eninzi ngaphezulu kwePatagonian Andes. Ngapha koko, le mimoya inesiphumo sesibini: isebenze njengomqobo wokunciphisa, kubangele ukuba yonke eminye imimoya ifike phantse yome kumathafa asePatagonia.

EArgentina kukho izinto ezinje ngobubanzi, isiqabu kunye nokuhamba komoya okungenelela kwiimpawu zemozulu. Yimimoya yalapha echaphazela imozulu yemimandla eyahlukeneyo yommandla waseArgentina. Imimoya emithathu ephambili yasekhaya eArgentina yiPampero, El Zonda kunye neLa Sudestada.

IPampero

Imvelaphi yegama ibuyela ekufikeni kokuqala kwabaseSpain bokuqala eRío de la Plata, abathi babethwa ngumoya onamandla ovela kwicandelo elisemazantsi-ntshona elizisa umoya ococekileyo nowomileyo. Abakholoniyali bakudala babona utshintsho lwemozulu kulo mmandla lwahluke kakhulu kunolo lwenzeka eYurophu.

Ipampero inemvelaphi yayo ngenxa kwiziko loxinzelelo oluphantsi imi kumathafa asembindini nasentshona yeArgentina. Eli ziko loxinzelelo oluphantsi lomelele ehlotyeni kwaye linokutsala imimoya ye-anticyclone yoMzantsi-Pacific.

Xa iziko loxinzelelo olusezantsi lenziwe, umzekelo xa amaqondo obushushu enyusa isixa esikhulu somoya ukuphakama, imikhosi yomoya engqongileyo zama ukubuyisela indawo esele ishiye isixa esincinci somoya. Ngesi sizathu, yonke imimoya esemazantsi e-Pacific Pacific anticyclone isiya kumbindi woxinzelelo olusezantsi.

Njengoko bekutshiwo ngaphambili, le mimoya ivela kwiPacific anti-cyclone iyabanda kwaye yomile, kuba isebenza njengomqobo kwaye iphulukana nokufuma. Ihlala iqhuma ngeentsuku zehlobo kwaye ubushushu bayo kunye nokufuma kuyanda ngenxa yokufika kwemimoya yorhwebo.

Yiyo loo nto uPampero eqhubela phambili ngokukhawuleza eLa Pampa, eseka uqhwithela ngaphambili kummandla wonxibelelwano phakathi kwezi zimbini, kuba banomahluko ngokobushushu kunye nobushushu.

IPampero bubunzima obomileyo nobomileyo, ngelixa elinye lifudumele kwaye lifumile, livela kwimimoya yorhwebo. Olu qhakamshelwano phakathi kwengqele eyomileyo kunye nefudumeleyo ibangela izaqhwithi zombane, iimvula ezininzi, nokuba zihlala zikhona ngesichotho kwaye zikhatshwa kukuhla ngequbuliso kweqondo lobushushu. Xa umphambili unyamalala emva kwethutyana, iyaphola yome kwakhona.

Xa umoya wePampero ulahla ukufuma kwawo xa unqumla intaba, kubanda kuphela kwaye komile, kubizwa ngokuba yiPampero eyomileyo. Xa ibangela imvula ngaphambili, ibizwa ngokuba yiPampero emanzi. Ukuba umoya wasezantsi-ntshona awuyivelisi imvula kwaye uvelise izivunguvungu zomhlaba, ubizwa ngokuba ngu-Dirty Pampero.

Uqikelelo lwePampero

Ukufumanisa ukuba uPampero uqhuma nini, izazi zemozulu zijonga inkqubo yoxinzelelo ephezulu ebekwe emazantsi eBrazil. Eli ziko loxinzelelo oluphezulu lubangela imimoya evuthuza iRío de la Plata kunye nomntla wonke kunye neziko lelizwe. Njengoko kuvuthuza le mimoya ubushushu kunye nokufuma zihlala zisanda kwaye uxinzelelo luphezulu.

Umoya unokuhlala phakathi kweentsuku ezimbini ukuya kwezintathu njengoko umoya obandayo nokomileyo ohlala kuyo yonke iPatagonia usondela. Xa eli xesha lidlulayo, uxinzelelo luqala ukwehla ngokuthe chu, ngelixa ukufuma kunye nobushushu kugcina amaxabiso aphezulu). Ngaphantsi kwezi meko, ukwehla koxinzelelo kuyabonwa (ukuya kuthi ga kwi-1.5 hPcal), kwaye ngequbuliso kubonwa kumazantsi okanye kumazantsi mpuma umgca omnyama wamafu eziqhubela phambili eRío de Plata. La mafu abonisa umphambili wokubanda okuhamba mpuma mpuma kuma-20 ukuya kuma-30 amaqhina.

Isudestada

I-sudestada lolunye uhlobo lomoya wasekhaya ovuthuza eArgentina. Imvelaphi yayo ibangelwa kukuvela kweziko loxinzelelo olusezantsi kunxweme lwePampean. Xa eli ziko loxinzelelo olusezantsi lenziwe, itsala yonke imimoya ejikeleze kwindawo yoxinzelelo oluphezulu kwiPasifiki yoMzantsi.

Iseli ekumzila wayo inqumla iPatagonia kwaye xa ibuyela kwiAtlantic iphinda ifake ukufuma kwakhona, ekhutshiweyo xa iphinda ingena kwilizwekazi. Xa le mvula isenzeka, zihlala zikhanya zihlala iintsuku ezintathu ukuya kwezintlanu. Abaqhele ukuhamba ngemichiza eqhubayo ngendlela eqhubekayo ngeli xesha lifutshane.

Iinyanga apho olu hlobo lomoya luqheleke kakhulu kwi iinyanga zika-Epreli no-Okthobha.

UZonda

Lo ngomnye umoya wasekhaya ovuthuzayo xa kwicandelo elingasempuma leentaba zaseLa Rioja, eSan Juan naseMendoza, iziko loxinzelelo olusezantsi lusekiwe nolutsala imimoya yeSouth Pacific Anticyclone. Ukusebenza kwayo kuyafana neSudestada.

Nje ukuba iqale, inyuka ngokuthe ngcembe njengoko ifikelela kwintaba kwaye iqondo lobushushu liyancipha. Oku kubangela ukufuma kunciphise, kuyila amafu avelayo imvula ngohlobo lwemvula nekhephu. Emva koko, ngesantya esingadlula kwiikhilomitha ezingama-50 ngeyure, umoya wehla ithambeka elingasempuma, ubangele ubushushu bawo bunyuke ngenxa yokukhuhlana kwee-molekyuli zomoya ngokuchasene nezinye njengoko zixinekile ngexesha lokuwa. Yiyo loo nto ekugqibeleni efikelela kunyawo lwentaba njenge umoya oshushu owomileyo, ngamaqondo obushushu akufutshane nama-40 ° C.

Nangona lo moya uyabacaphukisa abemi, uqinisekisa unikezelo lwamanzi oluqhubekayo ukunkcenkceshela kunye nezinye izinto ezinje ngokubonelela.

Njengoko ubona, iArgentina ilawulwa yimimoya emithathu yendawo, eneempawu ezizenza zahluke kwaye zinoxanduva lwemozulu yelizwe.
