Vil du vite om det blir regn p\u00e5 pikniken din eller sol p\u00e5 dagsturen din? I dag er det enkelt \u00e5 finne ut av det ved \u00e5 se p\u00e5 satellittbilder p\u00e5 TV eller p\u00e5 internett.<\/p>\n<\/div>\n

For bare noen ti\u00e5r siden var v\u00e6rmeldingene langt mer usikre. Et av problemene var at det bare var opprettet v\u00e6rstasjoner p\u00e5 noen f\u00e5 steder. Alle andre steder var v\u00e6rforholdene n\u00e6rmest et mysterium.<\/p>\n

I dag gir satellitter full dekning av hele jorden. Hvert eneste skysystem og hver eneste storm kan observeres mens de dannes og endrer seg.<\/p>\n

Den f\u00f8rste v\u00e6rsatellitten, TIROS (Television and InfraRed Observation Satellite), ble skutt opp 1. april 1960. Den var utstyrt med to TV-kameraer som sendte kornete bilder tilbake til jordoverflaten.<\/p>\n

Dagens v\u00e6rsatellitter er st\u00f8rre og langt mer avanserte. De gir meteorologene sv\u00e6rt detaljerte bilder og annen nyttig informasjon om atmosf\u00e6ren og havene, noe som hjelper dem med \u00e5 forbedre prognosene sine. Noen v\u00e6rsatellitter holder seg alltid over den samme delen av jordoverflaten. De befinner seg i geostasjon\u00e6re baner, 36 000 km over ekvator.<\/p>\n

Andre kretser rundt jorden fra Nordpolen til Sydpolen og tilbake igjen. De flyr mye n\u00e6rmere jordoverflaten (noen s\u00e5 lavt som 800 km) og leverer sv\u00e6rt detaljerte n\u00e6rbilder av v\u00e6rsystemer over hele verden.<\/p>","protected":false},"excerpt":{"rendered":"
