Future Changes in Drought Characteristics under Extreme Climate Change over South Korea

Table 6

Changes in the severity of drought in severe dry stages with three-month SPI less than −1.5 for past and future climate change projections. Observed severity of drought for the period 1976–2010 and projected change in severity of drought by each GCM and MME average for the period 2011–2099 for the climate change scenario. Difference is a percentage change in severity of drought between past and future periods, and positive value indicates increasing trend and vice versa. Note that the SPI series is calculated from a downscaled monthly precipitation using the four GCMs as inputs.
