Comparative analysis of indices of extreme rainfall events: Variations and trends from southern México

Studies from throughout much of the world have shown a general increase in extreme precipitation events over the past few decades, although most of these studies have focused on mid-to-high latitude land-based locations, particularly in the Northern Hemisphere. Many tropical and subtropical areas ha...
