Climate variability and forest fires in central and south‐central Chile
Abstract This paper evaluates the relationship between fire occurrence (number and burned area) and climate variability (precipitation and maximum temperatures) across central and south‐central Chile (32°–43° S) during recent decades (1976–2013). This region sustains the largest proportion of the Ch...
