precipitation, including the frequency of extreme precipitation, with substantial bias and
uncertainty relative to their representation of other fields. Thus, while theory predicts
changes in the hydrologic cycle under anthropogenic warming, there is generally low
confidence in future projections of extreme precipitation frequency for specific river basins. In
this paper, we explore whether a GCM simulates large‐scale atmospheric circulation indices …
Floods are responsible for significant loss of life and economic damages both within 39 the
United States (US) and worldwide. Flood impacts in the US are estimated at $ USD 8 bil-40
lion (in 2014 dollars) and 82 fatalities per year from 1984 to 2013 [NWS Internet Services 41
Team, 2015], while worldwide flood losses were estimated to be about $ USD 85 billion (in
42 2012 US dollars) in 1993 alone [Kundzewicz et al., 2013]. Furthermore, trends in popula-
43 tion and urbanization are expected to increase exposure to hydroclimate extremes …
