Interaction of elevation and climate change on fire weather risk

Most wildfire studies are regional to global in scale; however, many of the values interest and weather local phenomena that may give rise large spatial variability risk. We assessed interaction elevation climate on fire for Penticton Creek watershed southwestern Canada historic weather, five change scenarios. Daily temperature precipitation records spanning 100 years were generated using LARS-WG5 generator used calculate indices Canadian Forest Fire Danger Rating System. season length, restricted activity season, severity all projected increase by 2050s some scenarios further 2080s. Low mid-elevations had substantially worsening risks, whereas at highest elevations, risks mitigated continuation snowpack. Increasing temperatures lengthened while decreasing (increasing) exacerbated (ameliorated) intensity These results indicate more variable effects than literature. Over 24 million km 2 globally forestland have a similar or higher degree slope, highlighting need detailed topographic integration meet needs planners.
