Fig. 1a and 1b: Global (1a) and contiguous-US (1b) maps of mean precipitation (mm/day) for each of the four climatological seasons (e.g., spring is March 1-May 31), averaged over the period 1901-2000. The numbers at the upper right corner of each map are the means. In the US maps, "all" is the mean for all the 48 states, "W" is the mean over the 48 states west of 96°W and "E" is the mean east of 96°W.

Fig. 2a and 2b: Global (1a) and contiguous-US (1b) maps of precipitation change (mm/day) based on local linear trends for each of the four climatological seasons. for the period 1901-2000. The numbers at the upper right corner of each map are the means. In the US maps, "all" is the mean for all the 48 states, "W" is the mean over the 48 states west of 96°W and "E" is the mean east of 96°W.
