Figure 5

Superposed epoch analysis of fire occurrence and PDSI and ENSO. The y-axis shows scaled mean values of each of two climate indices during the year of fire (year 0 on the x-axis), for five years before the year of fire (negative values on the x-axis), and for four years after fire years (positive values). Blue colored bars indicate a value of a climate index in that year that is significantly departed from mean climate values at the 95 % confidence interval (CI).
