Uraganele sunt cele mai impresionante furtuni de pe P\u0103m\u00e2nt. Form\u00e2ndu-se deasupra apelor calde ale Oceanului Atlantic tropical, aceste uria\u0219e spirale se \u00eendreapt\u0103 spre vest, l\u0103s\u00e2nd \u00een urm\u0103 o d\u00e2r\u0103 de distrugere. Cel mai puternic uragan din acest an a fost uraganul Dean, care a lovit Mexicul dup\u0103 ce a str\u0103b\u0103tut insulele din Caraibe. Sateli\u021bii ESA au urm\u0103rit uraganul Dean \u00een timp ce v\u00e2nturile sale de 260 km\/h au generat valuri uria\u0219e \u0219i au d\u0103r\u00e2mat cl\u0103diri. Cel pu\u021bin opt persoane \u0219i-au pierdut via\u021ba.<\/p>\n<\/div>\n

Cunoa\u0219terea intensit\u0103\u021bii \u0219i a traiectoriei uraganelor este esen\u021bial\u0103 pentru emiterea avertismentelor prealabile. Din fericire, sateli\u021bii precum Envisat \u0219i ERS-2 ai ESA faciliteaz\u0103 acum studierea acestor furtuni imprevizibile. Instrumentele lor optice \u0219i radar pot monitoriza schimb\u0103rile survenite \u00een structura norilor, v\u00e2nturile \u0219i valurile, temperatura suprafe\u021bei m\u0103rii \u0219i \u00een\u0103l\u021bimea suprafe\u021bei m\u0103rii.<\/p>\n

Instrumentele optice de pe Envisat arat\u0103 v\u00e2rfurile norilor \u00eenv\u00e2rtindu-se, \u00een timp ce radarul vede prin nori pentru a ar\u0103ta cum v\u00e2nturile agit\u0103 valurile oceanului. Impulsurile radar ale altimetrului m\u0103soar\u0103 \u00een\u0103l\u021bimea suprafe\u021bei m\u0103rii cu o precizie de c\u00e2\u021biva centimetri. Scatterometrul radar de pe ERS-2 este deosebit de util, deoarece rezultatele sale nu sunt aproape deloc afectate de ploile toren\u021biale. Acesta poate furniza date privind viteza \u0219i direc\u021bia v\u00e2ntului deasupra suprafe\u021bei oceanului chiar din miezul celor mai violente furtuni.<\/p>\n

\u00centruc\u00e2t uraganele se alimenteaz\u0103 cu aer cald \u0219i umed, informa\u021biile privind temperatura m\u0103rii sunt de o importan\u021b\u0103 deosebit\u0103 pentru meteorologi. Unul dintre instrumentele de la bordul satelitului Envisat este un termometru spa\u021bial, care m\u0103soar\u0103 temperatura suprafe\u021bei m\u0103rii cu o precizie de o frac\u021biune de grad. Pe m\u0103sur\u0103 ce uraganul Dean \u00ee\u0219i pierde din intensitate, \u201eochii ESA din cer\u201d sunt deja \u00een alert\u0103 pentru urm\u0103toarea furtun\u0103 devastatoare.<\/p>","protected":false},"excerpt":{"rendered":"
