Hot Droughts and Hotter Extremes: Investigating Changes in Extreme Events in Hydrology, Aquatic Biogeochemistry, and Ecosystems

Submit an Abstract to this Session

Session ID#: 23658

Session Description:
Rapidly rising temperatures will increasingly change the character of extreme hydrologic events and associated disturbances of aquatic environments and natural ecosystems. The hot drought concept illustrates the perfect example—present and future droughts will have a more severe impact on hydrology, leading to differences in the disturbance of aquatic biogeochemical fluxes and associated vegetation when compared with past droughts of similar magnitude, due to the compounding effects of enhanced vapor pressure deficit and evaporative demand induced by warming temperatures. In this session, we invite submissions that investigate how increased warming is changing extreme events properties (e.g. magnitude, frequency, or duration) in hydrology including land surface climate feedbacks, and/or related disturbances of freshwater biogeochemistry and natural ecosystems. We welcome presentations that explore these changes in any terrestrial environment through the lens of hydrology, ecology, or aquatic biogeochemistry including those using observations (in-situ or remote sensing), experiments, and/or computational models.
