This display is intended to contrast the regions using patterns of color. In general, dark orange indicates high fi re, warm air temperatures, low precipitation, and low soil moisture, whereas dark blue indicates opposite conditions. The fi rst order similarities and dissimilarities among the regions are apparent and intuitive, e.g., wildfi re conditions in the Rocky Mountain region are highly dependent on temperature and moisture conditions. Counterintuitive patterns are displayed in the Southwest where high fi re years are associated with warm temperatures but wetter ranked conditions indicating the infl uence of high moisture levels on fuel supply and the association of lightning strikes with the summer monsoon.
