Lequel est le plus fiable ?

Well, I would say the mobile phone. There the current measurements (temperature, wind speed etc. at the moment) are based on reliable calibrated instruments ;-) A barometer at home is very likely not calibrated for ages, thus giving rather vague measurement. But what comes to weather forecast (for tomorrow and next days), that is often very inaccurate, no matter what...

Übereinstimmend?

See my reply to Didier above ;-)

Oh, that's a great comparison. How things do change!

Indeed! I remember times when listening the weather forecast from radio, and also checking out the weather maps on newspaper.

great idea!

a series which show how people are becoming slaves of this little thing. Good idea.
