Number of drought events in the analysed period (SSI-1) - Existing climate
Number of Drought events as defined by the SSI-1 indicator (Standardised Streamflow Index cumulated on a 1-month window) a consecutive series of days below -1 in present climate conditions.

The existing climate refers to the entire historical period of the last 40 years (1979 - 2016) the methodology employed for the computation is exhaustively explained in the Background paper.

There are reference periods for the existing climate and for the future scenarios the average duration is computed over such periods in a statistical sense (for future years from 2060 to 2100 are considered). The definition of the indicator is a series of consecutive days where the used indicator is below -1.
