These Meteosat images show what the clouds would have looked like to someone in the satellite. They are called 'Visible images', as distinct from 'Infra-red images', which show temperatures. On a visible image, you see clouds as though you were looking with your own eyes but in black and white. Clouds appear white. Snow appears white.
Deserts are light-coloured.
The sea appears dark, except where the sun is reflected from it. On an infra-red image, white indicates cold, black indicates warm. Today was considerably cooler at our schools in south-east Australia than it was on some days last week. In Spain and Portugal today, the weather has been quite settled. At the other end of the Mediterranean, in Cyprus, there has been a lot of sunshine, but temperatures have not been very high.
