Otok Reunion v Indijskem oceanu je za vsakogar sinonim za tropski raj. Vendar je 12. maja 2007 to \u010dudovito turisti\u010dno obmo\u010dje prizadela valovna nevihta z valovi, visokimi do 11 metrov. Mo\u010dni valovi so povzro\u010dili kaos in opusto\u0161enje: dva ribi\u010da sta izginila, ve\u010d pomolov se je zru\u0161ilo, domovi in hoteli pa so bili poplavljeni.<\/p>\n<\/div>\n

Dogodke, ki so vodili do tega uni\u010denja, je zabele\u017eil radarski instrument na krovu satelita Envisat agencije ESA. Ta instrument oddaja radijske signale, ki se odbijajo od morske povr\u0161ine, in zajema odmeve. Ti odmevi znanstvenikom razkrivajo velikost, vi\u0161ino in hitrost valov. V primeru poplav na otoku Reunion je satelit Envisat pokazal, da so valovi izvirali iz velike nevihte v ju\u017enem Atlantiku. V naslednjih treh dneh so se raz\u0161irili stran od sredi\u0161\u010da nevihte. Nekateri valovi so potovali proti severovzhodu skoraj 4000 km, preden so se zaleteli v otok Reunion.<\/p>\n

\u010ceprav so napovedovali, da bodo valovi dosegli otok, so na splo\u0161no pri\u010dakovali, da bodo visoki le nekaj metrov. Vendar analiza podatkov satelita Envisat ka\u017ee, da so bili valovi visoki pribli\u017eno 5 metrov in da so bili na odprtem morju med seboj zelo oddaljeni. Velika razdalja med valovi je znak, da so jih povzro\u010dili vetrovi z mo\u010djo nevihte. Ko so se valovi pribli\u017eevali obali, so upo\u010dasnili hitrost in podvojili vi\u0161ino.<\/p>\n

\u201cValovi so \u0161e vedno dejavniki presene\u010denja, ki so \u017eal lahko smrtno nevarni,\u201d je dejal Bertrand Chapron iz francoskega raziskovalnega in\u0161tituta za izkori\u0161\u010danje morja IFREMER. \u201cV bli\u017enji prihodnosti nameravamo uporabiti podatke o valovih, pridobljene s sistemom SAR (vesoljski radar), za napovedovanje \u010dasa njihovega prihoda in intenzivnosti.\u201d<\/p>","protected":false},"excerpt":{"rendered":"
