Figure 5: The change of correlation coefficients between long-transformed burned area and the number of consecutive dry days defined by the threshold daily rainfall amount (mm) by fire size group and ecoregion. The six fire size classes (represented by black dots) are <1.0 (small fire), 1.0–9.9 (moderately small fire), 10.0–49.9 (moderate fire), 50.0–99.9 (moderately large fire), 100.0–500.0 (large fire), and 500–1000 (extremely large fire), respectively.
