Abstract
During the 1962-2015 period, this region experienced successive regional long-term wet (1962-1995) and dry (1996-2015) dominated periods of more than 20 years each. During the wet period, precipitation intensity ranging from 1 to 12Â mm were 20% less likely to occur while event daily average precipitation and number of events increased by 10% and 11%, respectively. Also, the average daily precipitation occurred more often at lower intensities. In contrast, during the dry period, instantaneous intensity ranging from 1 to 12Â mm became more likely to occur (64% increase; 1996-2015) while event daily average precipitation and number of events decreased by 16% and 18%, respectively. Overall, comparisons with the baseline data (1962-2015) indicated that in the last 20 years, sub-hourly precipitation intensities have increased while daily event duration and extreme 5-min precipitation intensities larger than 24Â mm (precipitation intensification below extremes) have remained unchanged.
