Temporal United States Extreme Precipitation1997(Karl and Knight, 1997) 1910, precipitation has increased by about 10% across the contiguous United States. The increase in precipitation is reflected primarily in the heavy and extreme daily precipitation events. For example, over half (53%) of the total increase of precipitation is due to positive trends in the upper 10 percentiles of the precipitation distribution.
Warming Global Extreme Precipitation2013(Donat et al., 2013) in extreme precipitation are found, for example, for the number of heavy precipitation days (R10mm, Figure 8a) and the contribution from very wet days (R95pTOT, Figure 8b). Globally averaged, both indices display upward trends during the past 60 years. Similar patterns of change are also found for the average intensity of daily precipitation (Figure 8d)

Temporal India Extreme Precipitation2009(Krishnamurthy et al., 2009) a 1951-2003 gridded daily rainfall dataset for India... for the exceedance of the 99th percentile of daily rainfall, all locations where a significant increasing trend in frequency of exceedance is identified also exhibit a significant trend in rainfall intensity...there is support for the hypothesis that the frequency and intensity of extreme rainfall over India may be increasing over the previous 53 years
Anthropogenic Global Floods2002(Milly et al., 2002) find that the frequency of great floods increased substantially during the twentieth century. The recent emergence of a statistically significant positive trend in risk of great floods is consistent with results from the climate model, and the model suggests that the trend will continue.
Warming India Extreme Precipitation2008(Rajeevan et al., 2008) 104 years (1901-2004) of high resolution daily gridded rainfall data...The present study supports the hypothesis that the increasing trend of extreme rainfall events in the last five decades could be associated with the increasing trend of sea surface temperatures and surface latent heat flux over the tropical Indian Ocean
Temporal China Floods2005(Fengqing et al., 2005) is an increasing trend in flood disasters in Xinjiang during the second half of the 20th century, especially since the mid-1980s...the occurrence of flood disasters could be mainly induced by local human activities before the mid-1980s, and thereafter mainly by abnormal precipitation in Xinjiang...records showed that the number of heavy rainfall events and the frequency of rainstorm flood disasters increased since the 1980s
Warming Global Extreme Precipitation2009(Höppe and Grimm, 2009) the world...natural catastrophes have increased dramatically and are causing more and more damage...The upward trend in numbers of natural catastrophes is mainly due to weather-related events such as windstorms and floods...there is some justification for assuming that this trend is the result of changes in the atmosphere, most probably global warming.

Daily precipitation data for 147 meteorological stations from 1961-2000 and monthly discharge data for three stations in the basin have been analyzed...the rainstorms have aggravated floods in the middle and lower Yangtze River Basin in recent decades. The observed trends in precipitation and rainstorms are possibly caused by variations of atmospheric circulation (weakened summer monsoon) under climate warming.

Temporal Korea Extreme Precipitation2011(Jung et al., 2011) spatial and temporal variability of precipitation in Korea were investigated using 183 weather station data for 1973-2005...the increase of annual precipitation is mainly associated with the increase of frequency and intensity of heavy precipitation during summer season...this variation of precipitation is likely to increase flood and drought risk.
Warming United States Floods2015(Mallakpour?& Villarini, 2015), we show that while observational records (774 stream gauge stations) from the central United States present limited evidence of significant changes in the magnitude of floodpeaks, strong evidence points to an increasing frequency of flooding. These changes in flood hydrology result from changes in both seasonal rainfall and temperature across this region.
