Regional Climate Simulation for Arizona: Impact of Resolution on Precipitation
Figure 2
The cumulative rainfall for winter season (November 1–January 31), averaged over 7 winters from 2003 to 2009, from different sets of runs. (a) Rainfall produced by subgrid-scale cumulus parameterization (RAINC) from the 12 km runs. (b) Rainfall produced by grid-scale convection (RAINNC) from the 12 km runs. (c) RAINC from the 6 km runs with cumulus parameterization turned on (d) RAINNC from the 6 km runs with cumulus parameterization turned on. Boxes (i) and (ii) in (a) are the areas chosen for the further analysis of the time-series of rainfall in Figures 5–7. Box (i) is defined as 111.78°W–113.61°W and 31.90°N–33.69°N and box (ii) is defined as 109.35–112.02°W and 33.25°N–35.18°N. The plot shows the whole innermost domain, including the sponge layer for nesting.
