I dag er det nemt at finde ud af ved at se p\u00e5 satellitbilleder p\u00e5 tv eller p\u00e5 internettet.<\/p>\n<\/div>\n<p>For blot et par \u00e5rtier siden var vejrudsigterne langt mere usikre. Et af problemerne var, at der kun var opstillet vejrstationer p\u00e5 nogle f\u00e5 steder. Alle andre steder var vejrforholdene n\u00e6rmest et mysterium.<\/p>\n<p>I dag d\u00e6kker satellitterne hele Jorden. Man kan f\u00f8lge med i, hvordan hvert eneste skysystem og hver eneste storm opst\u00e5r og udvikler sig.<\/p>\n<p>Den f\u00f8rste vejrsatellit, TIROS (Television and InfraRed Observation Satellite), blev opsendt den 1. april 1960. Den var udstyret med to tv-kameraer, der sendte grynet billeder tilbage til jordoverfladen.<\/p>\n<p>Dagens vejrsatellitter er st\u00f8rre og langt mere avancerede. De forsyner meteorologerne med yderst detaljerede billeder og andre nyttige oplysninger om atmosf\u00e6ren og havene, som hj\u00e6lper dem med at forbedre deres prognoser. Nogle vejrsatellitter kredser altid over den samme del af Jordens overflade. De befinder sig i geostation\u00e6re baner, 36 000 km over \u00e6kvator.<\/p>\n<p>Andre kredser om Jorden fra Nordpolen til Sydpolen og tilbage igen. De flyver meget t\u00e6ttere p\u00e5 overfladen (nogle s\u00e5 lavt som 800 km) og leverer meget detaljerede n\u00e6rbilleder af vejrsystemer over hele verden.<\/p>","protected":false},"excerpt":{"rendered":"<p>Do you want to know whether it will rain on your picnic or be sunny for your day trip?
