Orkaner er de mest voldsomme storme p\u00e5 Jorden. Hver sommer dannes disse enorme, roterende storme over det varme Atlanterhav. N\u00e5r de bev\u00e6ger sig mod vest og rammer land, efterlader de et spor af \u00f8del\u00e6ggelse.<\/p>\n<\/div>\n

Vindst\u00f8d p\u00e5 over 200 km\/h river elledninger ned og j\u00e6vner bygninger med jorden. K\u00e6mpe b\u00f8lger og voldsomme regnskyl for\u00e5rsager ofte alvorlige oversv\u00f8mmelser.<\/p>\n

Orkaner optager enorme m\u00e6ngder energi og fugt, n\u00e5r de passerer over det varme hav. Nogle forskere mener, at den globale opvarmning kan f\u00f8re til flere orkaner og g\u00f8re dem endnu kraftigere.<\/p>\n

Den mest \u00f8del\u00e6ggende orkan i de senere \u00e5r var Katrina, som ramte det sydlige USA i august 2005. K\u00e6mpe b\u00f8lger og voldsom regn overvandt New Orleans\u2019 oversv\u00f8mmelsesv\u00e6rn, hvilket efterlod det meste af byen under vand. Mere end 1.800 mennesker mistede livet. Millioner af mennesker m\u00e5tte reddes, og mange er aldrig vendt tilbage.<\/p>\n

En af satellitternes vigtige opgaver er at give forvarsel om orkaner, s\u00e5 folk kan s\u00f8ge i sikkerhed. Rumfart\u00f8jer hj\u00e6lper ogs\u00e5 forskerne med at finde ud af, hvad der foreg\u00e5r inde i de hvirvlende storme.<\/p>\n

ESA\u2019s rumfart\u00f8jer MetOP-A, ERS-2 og Envisat kan f\u00f8lge deres uforudsigelige bev\u00e6gelser og unders\u00f8ge dem fra top til bund. Envisats instrumenter sender data tilbage om de skyer, der hvirvler rundt om stormens \u00f8je i midten. De m\u00e5ler ogs\u00e5 vindhastigheden omkring stormens \u00f8je.
Samtidig m\u00e5ler radarinstrumentet vind og b\u00f8lger over havet. Satellitten m\u00e5ler ogs\u00e5 temperaturen i de \u00f8verste skylag og p\u00e5 havoverfladen samt \u00e6ndringer i havniveauet.
Alle disse oplysninger er afg\u00f8rende for at kunne forudsige stormens forl\u00f8b.<\/p>","protected":false},"excerpt":{"rendered":"
