Orkaanid on Maa k\u00f5ige v\u00f5imsamad tormid. Need hiiglaslikud spiraalid tekivad Atlandi ookeani troopiliste soojade vete kohal ja liiguvad l\u00e4\u00e4ne poole, j\u00e4ttes endast maha h\u00e4vituse j\u00e4lgi. K\u00e4esoleva aasta seni v\u00f5imsaim orkaan on olnud orkaan Dean, mis tabas Mehhikot p\u00e4rast seda, kui oli l\u00e4binud Kariibi mere saared. ESA satelliidid j\u00e4lgisid orkaani Deani, kui selle 260 km\/h tuuled tekitasid hiiglaslikke laineid ja lammutasid hooneid. V\u00e4hemalt kaheksa inimest sai surma.<\/p>\n<\/div>\n

Orkaanide tugevuse ja liikumissuuna teadmine on varajaste hoiatuste v\u00e4ljastamiseks \u00fclioluline. \u00d5nneks on selliste satelliitide nagu ESA Envisat ja ERS-2 abil n\u00fc\u00fcd lihtsam neid ettearvamatuid tormi uurida. Nende optilised ja radariinstrumendid suudavad j\u00e4lgida muutusi pilvede struktuuris, tuules ja lainetes, merepinna temperatuuris ning merepinna k\u00f5rguses.<\/p>\n

Envisati optilised instrumendid n\u00e4itavad keerlevaid pilvede \u00fclemisi kihte, samas kui radar vaatab l\u00e4bi pilvede, et n\u00e4idata, kuidas tuuled merelaineid \u00fcles peksavad. Altimeetri radarimpulsid m\u00f5\u00f5davad merepinna k\u00f5rgust m\u00f5ne sentimeetri t\u00e4psusega. ERS-2 radar-scatteromeeter on eriti v\u00e4\u00e4rtuslik, kuna tugev vihm ei m\u00f5juta selle tulemusi peaaegu \u00fcldse. See suudab edastada andmeid tuule kiiruse ja suuna kohta ookeanipinnal isegi k\u00f5ige \u00e4gedamate tormide keskel.<\/p>\n

Kuna orkaanid toituvad soojast ja niiskest \u00f5hust, on mere temperatuuri andmed prognoosijate jaoks eriti olulised. \u00dcks Envisati pardal olevatest seadmetest on kosmoses asuv termomeeter, mis m\u00f5\u00f5dab merepinna temperatuuri murdosa t\u00e4psusega. Kui Dean vaibub, on ESA \u201esilmad taevas\u201c juba valmis j\u00e4rgmise laastava tormi jaoks.<\/p>","protected":false},"excerpt":{"rendered":"
