Extreme rainfall events have important societal impacts: for example, by causing flooding, replenishing reservoirs, and affecting agricultural yields.

Precipitation occurs about once every seven days in the western part of the region and once every three days in the southeastern part.77 The 10 rainiest days can contribute as much as 40 % of total precipitation in a given year.77 Generally, annual precipitation increased during the past century (by up to 20 % in some locations), with much of the increase driven by intensification of the heaviest rainfalls.77, 78,79 This tendency towards more intense precipitation events is projected to continue in the future.80

Observational data, evidence from field experiments, and quantitative modeling are the evidence base of the negative effects of extreme weather events on crop yield: early spring heat waves followed by normal frost events have been shown to decimate Midwest fruit crops; heat waves during flowering, pollination, and grain filling have been shown to significantly reduce corn and wheat yields; more variable and intense spring rainfall has delayed spring planting in some years and can be expected to increase erosion and runoff; and floods have led to crop losses.4, 5,6,7

In addition, the pattern of sea surface temperatures at low latitudes is extremely important for regional climate variations (shown, for example, by the increased likelihood of heavy winter rainfall in California when the eastern tropical Pacific warms in El Niño events).

In Niger, a recent analysis of hourly rainfall data (Shinoda et al., 1999) reveals that the droughts in the 1970s and 1980s were characterised primarily by a reduced frequency of heavy rainfall events (those exceeding 30 mm / day) rather than by a reduction in rainfall amount within heavy events.
