Table 2. For each site and each variable the mean and standard deviation (in brackets) of the anomalies from the average season for the periods without drought (white areas in Figs 1, 2, 3, 4, 5, 6), for the drought periods (grey areas in Figs 1, 2, 3, 4, 5, 6) and for the period preceding the first drought.
