\u00cenc\u0103 de duminic\u0103, cu aproximativ o sut\u0103 de recorduri lunare de temperatur\u0103 dobor\u00e2te \u00een toat\u0103 Fran\u021ba, Finist\u00e8re a fost plasat sub o avertizare galben\u0103 de val de c\u0103ldur\u0103. Acest lucru nu se mai \u00eent\u00e2mplase \u00een luna mai de c\u00e2nd sistemul a fost instituit \u00een 2004, potrivit M\u00e9t\u00e9o-France, care luni a extins avertizarea la  <\/span>18 departamente <\/span><\/a> concentrate \u00een vestul Fran\u021bei \u0219i \u00een capital\u0103, apoi a plasat 8 departamente sub o avertizare portocalie de val de c\u0103ldur\u0103 pentru mar\u021bi (Finist\u00e8re, Morbihan, Manche, Ille-et-Vilaine, Maine-et-Loire, Mayenne, Vend\u00e9e \u0219i Loire-Atlantique).<\/span><\/p>\n

Un val de c\u0103ldur\u0103 este definit ca o perioad\u0103 de trei zile consecutive \u00een care temperatura medie na\u021bional\u0103 (temperatura medie m\u0103surat\u0103 la nivel na\u021bional) este de cel pu\u021bin 23,4\u00b0C, o zi ating\u00e2nd 25,3\u00b0C sau mai mult. Fran\u021ba se confrunt\u0103 cu acest fenomen.<\/span><\/p>\n

\u201eAcesta este chiar cel mai timpuriu val de c\u0103ldur\u0103 observat vreodat\u0103 \u00een peste un secol<\/span><\/em> \u201d, noteaz\u0103 Cyril Wuest, meteorolog la <\/span> La Cha\u00eene M\u00e9t\u00e9o<\/span><\/a> *. <\/span><\/p>\n

El explic\u0103 faptul c\u0103 acest episod este cauzat de aerul cald din Sahara care se ridic\u0103 din Marea Mediteran\u0103 \u0219i se a\u0219eaz\u0103 deasupra Europei, unde r\u0103m\u00e2ne prins sub presiunea ridicat\u0103 a unui sistem anticiclonic blocat chiar deasupra \u021b\u0103rilor Benelux \u0219i a M\u0103rii Nordului. <\/span>\u201eAcest sistem \u00eempinge c\u0103ldura intens\u0103 spre sol \u0219i o re\u021bine pentru o perioad\u0103, cre\u00e2nd ceea ce este cunoscut sub numele de  <\/span><\/em>\u00abdom\u00bb deasupra Europei:<\/span><\/em><\/a>  f\u0103r\u0103 v\u00e2nt sau nori, c\u0103ldura devine auto-sustenabil\u0103 \u0219i se intensific\u0103 timp de zile \u00eentregi.\u201d<\/span><\/em><\/p>\n

\u00cen Fran\u021ba, valurile de c\u0103ldur\u0103 ar putea fi de zece ori mai frecvente dec\u00e2t \u00een \u200b\u200banii 1990<\/span><\/h2>\n

Aceste valuri de c\u0103ldur\u0103 recurente \u2013 \u0219i intensificarea lor \u2013 sunt un semn incontestabil al \u00eenc\u0103lzirii globale. \u00cen Europa, aceast\u0103 tendin\u021b\u0103 a sistemelor meteorologice de a se \u201ebloca\u201d (precum anticiclonul de aici care creeaz\u0103 aceast\u0103 \u201edom de c\u0103ldur\u0103\u201d) \u201e  <\/span>se explic\u0103 \u00een principal printr-o reducere a diferen\u021bei de temperatur\u0103 dintre diferite latitudini<\/span><\/em> \u201d, potrivit lui Cyril Wuest. <\/span><\/p>\n

Odat\u0103 cu schimb\u0103rile climatice, polii se \u00eenc\u0103lzesc mult mai repede dec\u00e2t restul globului, astfel \u00eenc\u00e2t diferen\u021ba de temperatur\u0103 dintre poli \u0219i tropice scade. Acest lucru duce la o \u00eencetinire a curen\u021bilor-jet (aceste v\u00e2nturi de mare altitudine care bat de la vest la est), care apoi tind s\u0103 \u0219erpuiasc\u0103. Drept urmare, anticicloanele \u0219i depresiunile r\u0103m\u00e2n \u00een acelea\u0219i regiuni zile, chiar s\u0103pt\u0103m\u00e2ni.\u201d<\/span><\/em> <\/span><\/p>\n

El afirm\u0103 c\u0103 aceast\u0103 pierdere de dinamism nu a mai fost observat\u0103 \u00eenainte. Dincolo de aceast\u0103 observa\u021bie, contextul \u00eenc\u0103lzirii globale intensific\u0103 aceste episoade de c\u0103ldur\u0103. <\/span>\u201eDe \u00eendat\u0103 ce se prev\u0103d temperaturi excep\u021bional de ridicate, recordurile sunt mai u\u0219or de dobor\u00e2t\u201d,<\/span><\/em> subliniaz\u0103 meteorologul.<\/span><\/p>\n

Fran\u021ba,  <\/span>prin intermediul planului s\u0103u na\u021bional de adaptare,<\/span><\/a>  se preg\u0103te\u0219te acum pentru o cre\u0219tere a temperaturii cu 4\u00b0C pe teritoriul s\u0103u continental p\u00e2n\u0103 la sf\u00e2r\u0219itul secolului. <\/span><\/p>\n

\u00cen acest scenariu, <\/span> M\u00e9t\u00e9o-France avertizeaz\u0103<\/span><\/a>  c\u0103 zilele cu valuri de c\u0103ldur\u0103 ar putea fi de zece ori mai frecvente dec\u00e2t \u00een \u200b\u200banii 1990. Aceste perioade de c\u0103ldur\u0103 persistent\u0103 ar putea <\/span>\u201eap\u0103rea \u00eenc\u0103 de la mijlocul lunii mai \u0219i dura p\u00e2n\u0103 la sf\u00e2r\u0219itul lunii septembrie\u201d.<\/span><\/em> <\/span><\/p>\n

\u00cen ceea ce prive\u0219te actualul \u201edom de c\u0103ldur\u0103\u201d, se a\u0219teapt\u0103 ca acesta s\u0103 persiste cel pu\u021bin p\u00e2n\u0103 la weekendul viitor. La Paris, ast\u0103zi, Canalul Saint-Martin s-a transformat \u00eentr-o piscin\u0103 pentru tinerii care au vrut s\u0103 se r\u0103coreasc\u0103 din cauza valului de c\u0103ldur\u0103.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
