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 subgridscale cumulus parameterization (RAINC) from the 12 km runs. (b) Rainfall produced by gridscale 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 timeseries 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.
