Characteristics of wildfire-igniting lightning in the western United States
Annually, over half the wildfires on federal lands in the conterminous western United States are caused by lightning. However, broad-scale characteristics of wildfire-igniting lightning flashes are poorly understood, and limit our ability to predict what role climate change might have on lightning patterns and in turn on future patterns of wildfire. I investigated lightning-wildfire relationships by comparing the characteristics of lightning flashes that start fires to those that do not across 29 ecoregions in the western US from 2003-2007. After accounting for ecoregional variation, I found ...
