MathWorks should have an office in my village ... !!

The idea is to compare everyday at 1:00 PM the temperature between my village Corbières (04220) in the South of France (near Marseille) and Meudon (French MathWorks Office which is near Paris)

After a few months , taking the decision to build a new office at Corbières should be easy ;-)

The information is gathered from Meteociel : http://www.meteociel.fr/previsions/1599/corbieres.htm and http://www.meteociel.fr/previsions/33209/meudon.htm. They use the American system Global Forecast System which is a global numerical weather prediction computer model.

If we look at the mean temperature, we can use the formula "Six degrees of separation" !!

In 4 months (121 days), it happened only 3 times that the temperature was higher in Paris ...
