Fig. 5 shows that AN and QM produce quite similar geographical
patterns, which was expected, as QM can be regarded as an evolution
of AN. These methods predict a diminution of precipitation on
most of the region, but also an increase near the Mediterranean
coast and the maritime Alps. These anomalies are only significant
near the Massif Central and in a region between the Alps and the
Rhône. On the other hand, the spatial structure of the mean calculated
by WT is different. In this case, the anomaly is wetter on a larger
area and dryer on the swiss part of the Alps. The changes are
significant mainly in the upper alpine region, towards Switzerland,
where the anomaly is negative. This first comparison shows that
the differences between methods can be important.
