Figure 9: Comparison of annual total precipitation and seasonal range (summer minus winter) in inches per month for the US from (a) observations, (b) the Canadian Model Scenario, and (c) the Hadley Model Scenario. Results are average inches/month for the period 1961-90. The model-simulated precipitation totals, their spatial patterns, and their seasonal ranges are in reasonable agreement with observations generated by the VEMAP project (Kittel et al. 1997, 1995; VEMAP Members, 1995). [Difference plots are also provided on the Web site containing the figures.]
