The climatology provides, for a given location or region, the time series of drought strength, the number, the mean duration, and the maximum duration of droughts of a given intensity, and the trend in drought incidence. The drought climatology is based on monthly standardized precipitation indices (SPIs) calculated on a 0.5° grid over the European region 35–70 °N and 35 °E–10 °W at time scales of 3, 6, 9, 12, 18, and 24 months for the period 1901–99.
