Precipitation Extreme Response to Warming across Different Scales

Extreme precipitation events are normally localized in time and in space. The small and short nature of these events pose a significant challenge for traditional general circulation models (GCMs). GCMs are known to underestimate the intensity of precipitation extremes, partially due to their coarse resolution. In this study we use a global storm resolving model (GSRM), with 3.25 kilometer horizontal resolution to explore the sale dependence of extreme precipitation in response to uniform warming and isolated radiative effect of CO2 increase. More specifically, we focus on response of the sub-daily and sub ~200km scales and show that the response can be different in different scales.
