Az \u00e1rv\u00edz a vil\u00e1g legk\u00f6lts\u00e9gesebb term\u00e9szeti katasztr\u00f3f\u00e1ja. A glob\u00e1lis \u00e1rv\u00edzk\u00e1rok k\u00f6lts\u00e9ge t\u00f6bb sz\u00e1zmilli\u00e1rd eur\u00f3t tesz ki. Csak a 2010. j\u00faliusi pakiszt\u00e1ni \u00e1rv\u00edz t\u00f6bb mint 7 milli\u00e1rd eur\u00f3 k\u00e1rt okozott.<\/p>\n<\/div>\n

Az \u00e1rvizek a part menti ter\u00fcleteken vagy a foly\u00f3k k\u00f6zel\u00e9ben fordulhatnak el\u0151. Amikor hatalmas v\u00edzt\u00f6megek bor\u00edtj\u00e1k el az alacsonyan fekv\u0151 ter\u00fcleteket, hatalmas anyagi k\u00e1rokat okozhatnak, \u00e9s \u00e9leteket is vesz\u00e9lyeztethetnek.<\/p>\n

Az eur\u00f3pai \u0171rtechnol\u00f3gia kulcsfontoss\u00e1g\u00fa eszk\u00f6z az \u00e1rvizek elleni k\u00fczdelemben. Az els\u0151 v\u00e9delmi vonalat a Meteosat \u00e9s a MetOp id\u0151j\u00e1r\u00e1si m\u0171holdak biztos\u00edtj\u00e1k. Ezek megmutatj\u00e1k a kialakul\u00f3 viharrendszereket, \u00e9s lehet\u0151v\u00e9 teszik a sz\u00e9l \u00e9s az es\u0151 pontos el\u0151rejelz\u00e9s\u00e9t.<\/p>\n

A hagyom\u00e1nyos kamer\u00e1kkal nappal, tiszta \u00e9gbolt mellett lehet r\u00f6gz\u00edteni az \u00e1rvizeket. Az \u00e1rvizek azonban \u00e1ltal\u00e1ban felh\u0151takar\u00f3 alatt alakulnak ki.<\/p>\n

Az ESA Envisat \u00e9s ERS-2 \u0171reszk\u00f6zei olyan radarberendez\u00e9sekkel vannak felszerelve, amelyek nappal \u00e9s \u00e9jjel egyar\u00e1nt k\u00e9pesek \u00e1tl\u00e1tni a felh\u0151ket. Ezek pontos f\u00f6ldhaszn\u00e1lati t\u00e9rk\u00e9peket k\u00e9sz\u00edtenek az el\u00e1rasztott ter\u00fcletekr\u0151l, megmutatva, hogy a v\u00edz mez\u0151ket, erd\u0151ter\u00fcleteket vagy be\u00e9p\u00edtett ter\u00fcleteket bor\u00edtott-e el.<\/p>\n

A radaradatokb\u00f3l ak\u00e1r az is kider\u00fclhet, hogy mennyi v\u00edz sziv\u00e1rgott be a talajba, \u00e9s hogy a \u201cszivacs\u201d megtelt-e m\u00e1r. A kor\u00e1bbi esem\u00e9nyekr\u0151l sz\u00f3l\u00f3 m\u0171holdas adatok felhaszn\u00e1l\u00e1s\u00e1val a j\u00f6v\u0151beli \u00e1rvizekre is fel lehet k\u00e9sz\u00fclni.<\/p>","protected":false},"excerpt":{"rendered":"
