Atmospheric water vapour. Coloured infrared satellite image of the whole Earth,showing upper atmospheric water vapour (yellow). North is at top. The central yellow area marks a dense area of water vapour evaporated by powerful equatorial solar radiation. Sub-tropical storms (black,northern hemisphere) return this water to the Earth's surface as rain. Their thick clouds (water droplets) absorb radiation at this wavelength (6.7 microns). There are advective weather systems (yellow swirls) in the temperate latitudes of both hemispheres. This image was taken by the American GOES-8 satellite on 23 September 1994 | |
