Correlation between the meteorological analyses and the seasonal and random trends of the temporal analyses.

The stationary (Dickey Fuller test of null hypothesis of temporal non stationary) and the autocorrelation (Ljung-Box test) were tested for each index. p0 represents the rain precipitations during the decades the measures have been done, p1 during the previous decade, and p2 during the decade before. Tmin, Tmoy and Tmax represent respectively the weekly minimum, average and maximum temperatures.
