Orkaner er de mest imponerende stormene p\u00e5 jorden. Hver sommer dannes disse enorme, roterende stormene over det varme Atlanterhavet. N\u00e5r de beveger seg vestover og treffer land, etterlater de seg et spor av \u00f8deleggelse.<\/p>\n<\/div>\n

Vind p\u00e5 over 200 km\/t river ned kraftledninger og jevner bygninger med jorden. Enorme b\u00f8lger og kraftig regn f\u00f8rer ofte til alvorlige oversv\u00f8mmelser.<\/p>\n

Orkaner tar opp enorme mengder energi og fuktighet n\u00e5r de passerer over det varme havet. Noen forskere mener at global oppvarming kan f\u00f8re til at antallet orkaner \u00f8ker og at de blir enda kraftigere.<\/p>\n

Den mest \u00f8deleggende orkanen de siste \u00e5rene var Katrina, som rammet den s\u00f8rlige delen av USA i august 2005. Enorme b\u00f8lger og piskende regn br\u00f8t gjennom flomvernet i New Orleans, slik at det meste av byen havnet under vann. Mer enn 1 800 mennesker mistet livet. Millioner av mennesker m\u00e5tte reddes, og mange har aldri kommet tilbake.<\/p>\n

En viktig oppgave for satellitter er \u00e5 gi tidlig varsel om orkaner, slik at folk kan komme seg i sikkerhet. Romfart\u00f8y hjelper ogs\u00e5 forskere med \u00e5 finne ut hva som skjer inne i de spiralformede stormene.<\/p>\n

ESAs romfart\u00f8y MetOP-A, ERS-2 og Envisat kan f\u00f8lge med p\u00e5 stormens uforutsigbare bevegelser og studere dem fra topp til bunn. Envisats instrumenter sender tilbake data om skyene som virvler rundt \u00f8yet i stormens sentrum. De m\u00e5ler ogs\u00e5 vindhastigheten rundt \u00f8yet.
Samtidig m\u00e5ler radarinstrumentet vind og b\u00f8lger over havet. Satellitten m\u00e5ler ogs\u00e5 temperaturen i de \u00f8vre skylagene og p\u00e5 havoverflaten, samt endringer i havniv\u00e5et.
All denne informasjonen er avgj\u00f8rende for \u00e5 kunne forutsi stormens utvikling.<\/p>","protected":false},"excerpt":{"rendered":"
