Regional Climate Simulation for Arizona: Impact of Resolution on Precipitation

Figure 5

A year-by-year comparison of the simulated winter seasonal-mean rainfall with observation using the PRISM dataset. The 7 winters are arranged from top to bottom. The observation is shown at the leftmost column, followed to the right by the simulations with 3 km, 6 km, and 12 km resolution. For brevity, for the 6 km runs only the case with cumulus convective scheme turned off is shown. The results for the case with convective scheme turned on are similar in pattern and magnitude.
