Abstract:Atmospheric vapor pressure deficit (VPD) is closely related to fire activity in the western United States (US). Here, we demonstrate that the western US experiences an escalating VPD trend driven by increased atmospheric capacity to hold water vapor due to global warming, intensifying aridity and fire risk, especially in summertime. Atop these drying trends, the leading VPD mode, with a pronounced decadal component, displays a center-of-action in the southwest US. In its dry phase, this mode is characterized b… Show more
