Here, U.S. composites of radar data from 1995 to 2013 are used to demonstrate the possibilities offered by such a data set. Three topics are touched: a) daily and annual cycles of precipitation, convection, and severe weather and what they can teach us about precipitation mechanisms; b) the influence of weekly activity cycles and of cities on precipitation and convection, and on the power and challenges of looking for a small signal in even such a large dataset; and c) the spatial and temporal distribution of the appearance of convection, and what it reveals on the importance of surface terrain properties for these events.>act 240001 modified by 132.206.246.51 on 8-8-2013-->
