Vortexul polar<\/a> este un vast fenomen ce const\u0103 \u00een v\u00e2nturi foarte puternice, care se manifest\u0103 la altitudini cuprinse \u00eentre 10 \u015fi 50 de kilometri deasupra Arcticii \u00een timpul iernii din emisfera nordic\u0103. Varia\u0163iile ap\u0103rute \u00een intensitatea sa \u015fi \u00een configura\u0163ia sa (form\u0103, temperatur\u0103 etc.) pot avea consecin\u0163e asupra st\u0103rii vremii din Europa, determin\u00e2nd, de exemplu, o sc\u0103dere important\u0103 a temperaturilor.<\/p>\n\u201eModelele computerizate indic\u0103 o perturbare major\u0103 a vortexului \u00een atmosfera \u00eenalt\u0103 (\u00eentre 10 \u015fi 50 de kilometri altitudine) \u00een acest \u00eenceput al lunii noiembrie\u201d, care \u201enu s-a mai produs \u00eenainte de sf\u00e2r\u015fitul lui noiembrie (…) din anii 1950\u201d, a transmis M\u00e9t\u00e9o France.<\/p>\n
Aceast\u0103 perturbare apare, cel mai adesea, \u00een ianuarie sau \u00een februarie.<\/p>\n
O astfel de precocitate \u201eeste excep\u0163ional\u0103\u201d, a declarat Grahame Madge, purt\u0103tor de cuv\u00e2nt al Met Office din Regatul Unit. O posibil\u0103 explica\u0163ie ar fi \u201eamplitudinea fenomenului El Nino din Pacific\u201d \u00een acest an, a ad\u0103ugat el.<\/p>\n
Met Office a explicat c\u0103 o sl\u0103bire a vortexului, cauzat\u0103 mai ales de o \u00eenc\u0103lzire stratosferic\u0103, poate s\u0103 creasc\u0103 probabilitatea ca aerul mai rece s\u0103 coboare din Arctica spre sud, precum \u015fi s\u0103 determine o perturbare a regimului v\u00e2nturilor de vest, duc\u00e2nd la o vreme mai secetoas\u0103.<\/p>\n
\u00cen acest moment, M\u00e9t\u00e9o France estimeaz\u0103 c\u0103 urm\u0103rile pentru starea vremii r\u0103m\u00e2n \u201efoarte incerte\u201d \u00een Fran\u0163a \u015fi \u201evor depinde de modul \u00een care va evolua perturbarea”.<\/p>\n
Fenomenul ar putea \u201es\u0103 sporeasc\u0103 \u00een urm\u0103toarele s\u0103pt\u0103m\u00e2ni\u201d diferen\u0163ele de temperatur\u0103 dintre nordul \u015fi sudul Europei, cu o vreme mai rece \u00een nord \u015fi mai cald\u0103 \u00een sud, a ad\u0103ugat agen\u0163ia francez\u0103.<\/p>\n
\u00cens\u0103 aceast\u0103 precocitate ar putea, de asemenea, s\u0103 genereze efecte \u201emai pu\u0163in marcante\u201d dec\u00e2t atunci c\u00e2nd perturbarea se produce \u00een plin\u0103 iarn\u0103, a precizat Grahame Madge.<\/p>\n
\u201e\u00centr-adev\u0103r, temperaturile din regiunile care reprezint\u0103 sursa acestor mase de aer, precum Siberia \u015fi Arctica, nu sunt \u00eenc\u0103 la fel de sc\u0103zute precum cele care vor exista \u00een februarie\u201d, a explicat el.<\/p>\n
De asemenea, \u201eva trebui ca un anumit num\u0103r de elemente s\u0103 se manifeste \u00eentr-o ordine precis\u0103 pentru ca noi s\u0103 putem s\u0103 resim\u0163im efectele, iar o astfel de evolu\u0163ie nu este deloc garantat\u0103\u201d, a ad\u0103ugat purt\u0103torul de cuv\u00e2nt de la Met Office.<\/p>\n
