%X the 12-month standardized precipitation index (spi) is used to identify and assess drought severity in m¨¦xico during the 1949-2098 period under the a2 emissions scenario of the intergovernmental panel on climate change (ipcc). the analysis indicates more frequent and severe drought events in m¨¦xico, shown by a negative trend of the 12-month projected spi time series. furthermore, this study concludes that projected future drought events would surpass the time-length, magnitude and frequency of those modelled during the second half of the 20th century.
