Ngokuqinisekileyo uvile amawakawaka ngamaxesha kwiindaba malunga ne I-Azores anticyclone. Yimeko yemeteorological echaphazela imozulu yePeninsula yase-Iberia kwaye kufuneka iqondwe kakuhle kakhulu ukuze kuqondwe izizathu kunye nemiphumo enayo kwimozulu yaseSpain. Izazinzulu ziye zafunda le anticyclone iminyaka emininzi kwaye inokubaluleka okukhulu kuqikelelo lwemozulu.
Ngenxa yesi sizathu, siza kunikezela eli nqaku ukukuxelela ukuba yintoni i-Azores anticyclone, yintoni iimpawu zayo, izizathu kunye nemiphumo.
Yintoni i-anticyclone
Into yokuqala kukwazi ukuba yintoni i-anticyclone. I-anticyclone yindawo yoxinzelelo oluphezulu (ngaphezu kwe-1013 Pa) apho uxinzelelo lwe-atmospheric luphezulu kunoxinzelelo lomoya olujikelezileyo kwaye luyanda ukusuka kwi-periphery ukuya kumbindi. Idla ngokunxulunyaniswa nemozulu eqhelekileyo ezinzile, isibhakabhaka esicacileyo, kunye nokukhanya kwelanga.
Ikholamu ye-anticyclone izinzile ngakumbi kunomoya ojikelezileyo. Ngokulandelayo, umoya owela ezantsi udala into ebizwa ngokuba iyatshona, oko kuthetha ukuba kuthintela ukwakheka kwemvula. Ewe kunjalo, kufuneka kuthathelwe ingqalelo ukuba indlela ehla ngayo umoya iya kwahluka ngokuxhomekeke kubume belizwe obukuwo.
Le airflows ye-anticyclonic kulula ukuyiphuhlisa ehlotyeni, iqhubekisela phambili ixesha elomileyo. Ngokungafaniyo nenkanyamba, leyo kulula ukuqikelela, badla ngokuba nemilo nehambo engaqhelekanga. Ukuthetha ngokubanzi, i-anticyclones inokwahlulwa ibe ngamaqela amane okanye iindidi.
Yintoni iAzores anticyclone
Ukuqala nje, ukuba yi-meteorologist kwi-Azores kunokubonakala kungumsebenzi olula, kodwa yonke into ekhazimlayo ayiyogolide. Ii-anticyclones ezidumileyo ungasoloko uguqulela kwimozulu ezinzileyo phezu kwechwebakazi. Kwilizwe lethu ngokuqhelekileyo isiqinisekisa imozulu eyomileyo nenelanga ehlotyeni, kodwa iyenzeka nakwiindawo zethu zasebusika. Ikwakwenza oku ngokunyakazisa umoya kwaye ibangele iziqendu ezidumileyo zongcoliseko lwasebusika kwizixeko ezikhulu. Ke ngoko, inoxanduva lokumakisha ixesha kwisibanzi sethu. Kodwa yenziwa njani?
Ukubunjwa kwayo kuhambelana nokujikeleza kwe-atmospheric kunye nokwahlukana kweqondo lokushisa phakathi kwe-ikhweyitha kunye nezibonda. Imitha yelanga iguqulela kubushushu obuphezulu kwimimandla ye-ikhweyitha, ebangela ukuba umoya ofudumeleyo unyuke ngenxa yokuxinana kwawo. Umoya ofudumeleyo awunyuki kuphela kwindawo ephakamileyo, kodwa nakwi-latitude.
Ukuya kuthi ga kuma-30°-40°N. Apha, ihla ngenkqubo yokucwila ekhokelela kwi-updraft eqhubekayo kunye ne-zero, ukudala i-anticyclone. Ngoko oku kuguqulela kwimozulu ezolileyo kunye nelanga.
Ehlotyeni, idla ngokusondela eNtshona Yurophu, ithintele ukungena kwezaqhwithi ezisuka kwiimitha ezisemantla. Ebusika, kwelinye icala, sithe qelele kulo kuba ukuthotywa kwenzeka emazantsi. Igalelo lesivunguvungu kunye nomoya obandayo ke ngoko ukhululekile ukuba uzulazule ngokukhululekileyo kwiindawo ezisezantsi. Isimo sezulu kwiPeninsula yase-Iberia siya kuchaphazeleka ngokutyhala kunye nokutsalwa kwe-anticyclones kunye nezivunguvungu ezivela ngasentla.
Injani imozulu ngeAzores anticyclone?
Nangona eli chwebakazi libizwa ngegama le-anticyclone idumileyo, imozulu yesiqithi ixakekile kunokuba besicinga ekuqaleni. Inyaniso, imozulu iyatshintsha kakhulu kwaye ifumile. Ewe kunjalo, ukuba uceba ukuya kweli hlotyeni, musa ukwenza oko ucinga ngelanga kunye neendawo zokuya elunxwemeni. Kunoko, cinga ngezi ziqithi njengendlela yokuphepha ubushushu. Uya kufumana amaqondo obushushu aphakathi, kodwa ngokuqinisekileyo uya kumangaliswa ukuba kunetha ngenye imini.
Kuxhomekeka kwiziqithi esizityelelayo, imozulu iya kwahluka, nangona ubukhulu becala ipholile kungekho xesha lonyaka lakubalela kunye nehlobo elipholileyo. Kwiziqithi ezisembindini nakwimpuma, imozulu ipholile, ihlobo elomileyo nelipholileyo.
Ngenxa yoko, ihlobo libandi kakhulu kunobusika, nezona mvula zininzi phakathi kukaOktobha noMatshi. Ngokubanzi, kukho umahluko omncinane phakathi kwexesha lonyaka kunye nelinye. Into eya kuhlala ikhona iya kuba kukufuma okuninzi. Utshintsho lwemozulu olunxulunyaniswa nempembelelo yaselwandle enika ichwebakazi uhlaza kunye nenxalenye yobuhle bomhlaba obuyiphawulayo.
Umahluko kunye nezaqhwithi
Kuqhelekile ukubhidanisa i-anticyclones kunye nezaqhwithi, kuba izaqhwithi zikwabizwa ngokuba zii-cyclone. Noko ke, zichasene noko. Ukuqonda umahluko omkhulu phakathi kwezi meko zimbini zemozulu, masiqonde ukuba yintoni na inkcazo yoqhwithela.
Izaqhwithi ngumoya osasazeke kancinane othanda ukunyuka. Yindawo apho uxinzelelo lwe-atmospheric luphantsi kunommandla ojikelezayo. Ukunyuka komoya ukuya phezulu kuthanda ukubunjwa kwamafu, ngoko ke ukuveliswa kwemvula. Iingqushu ziphenjelelwa ngumoya obandayo, yaye ubude bazo buxhomekeke kubungakanani bomoya obandayo eziwuphetheyo. Ezi ntlobo zobunzima bomoya azinzile kakhulu, zenza kwaye zihamba ngokukhawuleza.
Kumantla eikhweyitha, isaqhwithi sijikeleza ngasekunene. Ezi ngxilimbela zomoya zizisa nemozulu engazinzanga, amafu, imvula okanye isaqhwithi, kwaye ngamanye amaxesha ikhephu ebusika.
I-Azores anticyclone kunye nokutshintsha kwemozulu
Uphononongo lokufudumala kwehlabathi lubonisa ukuba i-Azores anticyclone inokuba iye yaqina kwiminyaka yakutshanje, izimeleyo kwi-oscillations eqhelekileyo yohlobo lwe-ENSO, ekhokelela kwiziganeko zemvula ezigqithiseleyo kumazantsi-mpuma e-United States. Kusenokubakho utshintsho lwe-latitudinal ye-crest, kunye neemodeli ezithile zekhompyuter ezimele ukwandiswa okungaphaya ngasentshona kwe-anticyclone yexesha elizayo. Nangona kunjalo, ebusika 2009-2010, i-anticyclone yaba ncinane, yafudukela kumntla-mpuma, kwaye yaba buthathaka kunesiqhelo, leyo kubangele ukunyuka okukhawulezileyo kwamaqondo obushushu kumbindi weAtlantiki.
Njengoko ubona, i-Azores anticyclone ibaluleke kakhulu kwimozulu yepeninsula kwaye iluncedo kakhulu ukuqikelela imozulu. Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga ne-Azores anticyclone kunye neempawu zayo.
