Hydroclimate and Extremes in the Western United States in a Changing Climateagu.confex.com The western United States is particularly susceptible to adverse impacts from a wide range of hydroclimate events including droughts, floods, heat waves, fire weather extremes, and compounding extremes resulting from different hydroclimate hazards occurring concurrently or in sequence. Anthropogenic forcing can shape such risks by altering temperature, precipitation, and humidity in ways that modify vapor pressure deficit, evapotranspiration, precipitation phases and intensity, and snowpack. It is thus crucial to advance the fundamental knowledge of drivers of hydroclimatic processes and extremes under the present and future climates in this region.
This session focuses on recent advancements in understanding hydroclimate and related extremes/hazards in the western United States under the present and future climates. Abstracts focused on physical processes, observations, numerical modeling, and societal/environmental impact analysisâparticularly those examining droughts, floods, snowpack, atmosphere-land interactions as well as the role of temperature, precipitation, and humidity in driving hydroclimatic processesâare welcome.

Long-duration and in some cases record-breaking heatwave across much of CA in early July - Weather Westweatherwest.com June ended up being a very warm (and warmer than expected) month in CA except at immediate coast June was...well, a pretty toasty one across most of the Southwest (unless you happen to live close to the immediate Pacific coast!). In fact, across a large portion of the interior Southwest (including some desert and mountain
Future fire events are likely to be worse than climate projections indicate – these are some of the reasons whywww.publish.csiro.au Background Climate projections signal longer fire seasons and an increase in the number of dangerous fire weather days for much of the world including Australia.Aims Here we argue that heatwaves, dynamic fire–atmosphere interactions and increased fuel availability caused by drought will amplify potential fire behaviour well beyond projections based on calculations of afternoon forest fire danger derived from climate models.Methods We review meteorological dynamics contributing to enhanced fire behaviour during heatwaves, drawing on examples of dynamical processes driving fire behaviour during the Australian Black Summer bushfires of 2019–20.Results Key dynamical processes identified include: nocturnal low-level jets, deep, unstable planetary boundary layers and fire–atmosphere coupling.Conclusions The future scenario we contend is long windows of multi-day fire events where overnight suppression is less effective and fire perimeters will expand continuously and aggressively over multiple days and nights.Implications Greater overnight fire activity and multi-day events present strategic and tactical challenges for fire management agencies including having to expand resourcing for overnight work, manage personnel fatigue and revise training to identify conditions conducive to unusually active fire behaviour overnight. Effective messaging will be critical to minimise accidental fire ignition during heatwaves and to alert the community to the changing fire environment
