Review of Variability in the North American Monsoon
Annual Precipitation Graphs for Selected Sites
Figure 1. Seasonal distribution of precipitation for southwestern North America. The largest peaks in mid-to-late summer rainfall (i.e., monsoonal)are found in northwestern Mexico. Note that northeastern Mexico and Texas display early summer/early fall precipitation peaks. Areas south of the broken line receive 50% of their annual rainfall during July, August and September (after Douglas et al. 1993).
