O mo\u017enom v\u00fdvoji informoval port\u00e1l Severe Weather Europe<\/a>, ktor\u00fd analyzoval aktu\u00e1lne sez\u00f3nne meteorologick\u00e9 modely aj v\u00fdsledky viacer\u00fdch vedeck\u00fdch \u0161t\u00fadi\u00ed. Meteorol\u00f3govia z\u00e1rove\u0148 zd\u00f4raz\u0148uj\u00fa, \u017ee nejde o klasick\u00fa predpove\u010f zimy. Hovoria iba o faktoroch, ktor\u00e9 m\u00f4\u017eu zv\u00fd\u0161i\u0165 pravdepodobnos\u0165 chladnej\u0161ieho priebehu po\u010dasia v druhej polovici zimy. To, \u010di sa tento scen\u00e1r napln\u00ed, uk\u00e1\u017eu a\u017e nasleduj\u00face mesiace.<\/p>\n

V\u0161etko sa za\u010d\u00edna nad severn\u00fdm p\u00f3lom<\/p>\n

Jedn\u00fdm z najd\u00f4le\u017eitej\u0161\u00edch hr\u00e1\u010dov zimn\u00e9ho po\u010dasia je pol\u00e1rny v\u00edr. Ide o rozsiahlu cirkul\u00e1ciu vzduchu vysoko nad severn\u00fdm p\u00f3lom, ktor\u00e1 po\u010das zimy dr\u017e\u00ed najchladnej\u0161\u00ed arktick\u00fd vzduch na severe. Pokia\u013e je pol\u00e1rny v\u00edr siln\u00fd a stabiln\u00fd, studen\u00fd vzduch zost\u00e1va tam, kde m\u00e1.<\/p>\n

Ke\u010f v\u0161ak zoslabne alebo sa naru\u0161\u00ed, jeho prirodzen\u00e1 bari\u00e9ra sa otvor\u00ed a \u010das\u0165 arktick\u00e9ho vzduchu sa m\u00f4\u017ee presun\u00fa\u0165 ju\u017enej\u0161ie. Pr\u00e1ve vtedy rastie \u0161anca, \u017ee mrazy \u010di sne\u017eenie zasiahnu v\u00e4\u010d\u0161iu \u010das\u0165 Eur\u00f3py. Pod\u013ea najnov\u0161ej anal\u00fdzy moment\u00e1lne existuj\u00fa tri faktory, ktor\u00e9 by mohli tak\u00fdto scen\u00e1r podpori\u0165.<\/p>\n

Pol\u00e1rny v\u00edr pritom neovplyv\u0148uje po\u010dasie iba na nieko\u013eko dn\u00ed. Ak d\u00f4jde k jeho v\u00fdraznej\u0161iemu naru\u0161eniu, n\u00e1sledky sa m\u00f4\u017eu prejavova\u0165 aj nieko\u013eko t\u00fd\u017ed\u0148ov. Pr\u00e1ve preto meteorol\u00f3govia venuj\u00fa jeho v\u00fdvoju tak\u00fa pozornos\u0165 u\u017e po\u010das leta a jesene, ke\u010f sa za\u010d\u00ednaj\u00fa objavova\u0165 prv\u00e9 n\u00e1znaky toho, ako by mohla vyzera\u0165 nadch\u00e1dzaj\u00faca zima.<\/p>\n

Mimoriadne siln\u00e9 El Ni\u00f1o m\u00f4\u017ee v\u00fdrazne zamie\u0161a\u0165 kartami<\/p>\n

Prv\u00fdm z nich je v\u00fdvoj klimatick\u00e9ho javu El Ni\u00f1o v Tichom oce\u00e1ne. Modely moment\u00e1lne nazna\u010duj\u00fa, \u017ee by mohlo \u00eds\u0165 o jednu z najsilnej\u0161\u00edch epiz\u00f3d za posledn\u00e9 desa\u0165ro\u010dia, takzvan\u00e9 super El Ni\u00f1o. Pr\u00e1ve po\u010das siln\u00fdch epiz\u00f3d El Ni\u00f1o sa pod\u013ea historick\u00fdch \u00fadajov \u010dastej\u0161ie objavuje n\u00e1hle stratosf\u00e9rick\u00e9 oteplenie. Ide o jav, ktor\u00fd dok\u00e1\u017ee oslabi\u0165 alebo naru\u0161i\u0165 pol\u00e1rny v\u00edr.<\/p>\n

Sez\u00f3nne modely z\u00e1rove\u0148 nazna\u010duj\u00fa, \u017ee najv\u00fdraznej\u0161ie oslabenie by mohlo pr\u00eds\u0165 po\u010das janu\u00e1ra 2027. Aj v tomto pr\u00edpade v\u0161ak meteorol\u00f3govia zd\u00f4raz\u0148uj\u00fa, \u017ee ide o dlhodob\u00fd v\u00fdh\u013ead, ktor\u00fd sa bude e\u0161te spres\u0148ova\u0165.<\/p>\n

Siln\u00e9 El Ni\u00f1o pritom neovplyv\u0148uje iba zimn\u00e9 po\u010dasie. Tento jav pravidelne men\u00ed rozlo\u017eenie zr\u00e1\u017eok aj tepl\u00f4t vo viacer\u00fdch \u010dastiach sveta a b\u00fdva spojen\u00fd s \u010dastej\u0161\u00edmi extr\u00e9mami po\u010dasia. Pr\u00e1ve preto patr\u00ed medzi najd\u00f4le\u017eitej\u0161ie klimatick\u00e9 faktory, ktor\u00e9 meteorol\u00f3govia sleduj\u00fa pri tvorbe sez\u00f3nnych v\u00fdh\u013eadov.<\/p>\n

V\u00fdznamn\u00fa \u00falohu zohr\u00e1vaj\u00fa aj vetry vysoko nad Zemou<\/p>\n

Druh\u00fdm sledovan\u00fdm faktorom je takzvan\u00e1 kv\u00e1zidvojro\u010dn\u00e1 oscil\u00e1cia, zn\u00e1ma pod skratkou QBO. Ide o pravideln\u00e9 zmeny smeru vetra vo vysokej vrstve atmosf\u00e9ry nad rovn\u00edkom. Sama osebe e\u0161te neznamen\u00e1, \u017ee pol\u00e1rny v\u00edr zoslabne. V kombin\u00e1cii so siln\u00fdm El Ni\u00f1o v\u0161ak m\u00f4\u017ee pod\u013ea odborn\u00edkov vytvori\u0165 podmienky, ktor\u00e9 naru\u0161enie v\u00edru podporia, najm\u00e4 v druhej polovici zimy.<\/p>\n

Tret\u00edm faktorom je mno\u017estvo morsk\u00e9ho \u013eadu v Arkt\u00edde. V\u00fdskumy ukazuj\u00fa, \u017ee ke\u010f je v oblasti Barentsovho a Karsk\u00e9ho mora menej \u013eadu ne\u017e zvy\u010dajne, pol\u00e1rny v\u00edr b\u00fdva \u010dastej\u0161ie slab\u0161\u00ed. Presne tak\u00fdto v\u00fdvoj nazna\u010duj\u00fa aj aktu\u00e1lne \u00fadaje. Ak sa potvrd\u00ed aj po\u010das jesene, m\u00f4\u017ee pod\u013ea autorov anal\u00fdzy zv\u00fd\u0161i\u0165 pravdepodobnos\u0165, \u017ee zimn\u00e1 cirkul\u00e1cia nad severnou pologu\u013eou bude menej stabiln\u00e1.<\/p>\n

\u010co z toho vypl\u00fdva pre Slovensko<\/p>\n

Pre Slovensko to zatia\u013e neznamen\u00e1, \u017ee n\u00e1s ur\u010dite \u010dak\u00e1 tuh\u00e1 zima. Ani oslaben\u00fd pol\u00e1rny v\u00edr toti\u017e automaticky neprinesie mrazy do ka\u017edej \u010dasti Eur\u00f3py. Zvy\u0161uje v\u0161ak pravdepodobnos\u0165, \u017ee sa po\u010das zimy objavia v\u00fdraznej\u0161ie vp\u00e1dy studen\u00e9ho arktick\u00e9ho vzduchu. Tie m\u00f4\u017eu prinies\u0165 chladnej\u0161ie obdobia, viac sne\u017eenia aj v\u00e4\u010d\u0161ie v\u00fdkyvy po\u010dasia.<\/p>\n

O tom, ako bude zima napokon vyzera\u0165, rozhodn\u00fa udalosti v atmosf\u00e9re po\u010das nasleduj\u00facich mesiacov. Meteorol\u00f3govia preto bud\u00fa v\u00fdvoj pol\u00e1rneho v\u00edru, El Ni\u00f1o aj stav arktick\u00e9ho \u013eadu na\u010falej podrobne sledova\u0165.<\/p>\n
