The basic results seen in previous studies also were manifested in the S-Pol 3D dataset; that is, convective rainfall increased after noon local time in the highest terrain, and the rainfall maximum there led the maxima at lower elevations.…”

“…Terrain bands were broken down as follows: Gulf of California (over water; 12 726 grid points in the DEM), coastal plain (0-500 m MSL; 6713 grid points), 500-1500 m MSL (2934 grid points), and .1500 m MSL (4852 grid points). The land terrain bands roughly corresponded to the low, middle, and high elevation groups used for the NAME Event Rain Gauge Network (NERN) data (Gochis et al 2004). See Fig.…”

“…As noted by Nesbitt et al (2008), monsoon rainfall in the NAME region provides between 40% and 80% of the annual water resource (Douglas et al 1993;Adams and Comrie 1997;Brito-Castillo et al 2003;Gochis et al 2006). Thus, there exists a need for improved hydrological prediction and water resource management there.…”

The spatial and temporal variability of convection during the North American Monsoon Experiment (NAME) was examined via analysis of three-dimensional polarimetric radar data. Terrain bands were defined as the Gulf of California (over water) and elevations of 0-500 m above mean sea level (MSL; coastal plain), 500-1500 m MSL, and .1500 m MSL. Convective rainfall over the Gulf typically featured the smallest values of median volume diameter (D 0 ) regardless of rain rate. Gulf convection also contained reduced precipitationsized ice water mass but proportionally more liquid water mass compared to convection over land. These maritime characteristics were magnified during disturbed meteorological regimes, which typically featured increased precipitation over the Gulf and adjacent coastal plain. Overall, the results suggest increased reliance on warm-rain collision and coalescence at the expense of ice-based precipitation growth processes for convective rainfall over the Gulf, relative to the land. Over land D 0 , ice, and liquid water mass all increased with decreasing terrain elevation, suggesting intensification of convection as it moved off the Sierra Madre Occidental. The results are consistent with the hypothesis that both warm-rain and ice-based rainfall processes play important roles in precipitation formation over land. Coastal-plain convection underwent microphysical modifications during disturbed meteorological regimes that were similar to Gulf convection, but the changes were less dramatic. High-terrain convection experienced little microphysical variability regardless of meteorological regime.

“…Complementing national networks operated by the NWS, the SMN, and the Mexican CNA, hundreds of new rain gauges were installed by NAME investigators in the tier-1 region to fill in data-sparse regions and to help ameliorate a low-elevation bias in the existing observing network (cf. Gochis et al 2003Gochis et al ,2004. The variety of new gauge types included simple wedge gauges that record daily accumulations, event-logging tipping-bucket gauges, and sophisticated siphoning tipping-bucket gauges.…”
