Session ID#: 17072

Session Description:
Drought is among the costliest natural hazards in the U.S. and around the world. Understanding drought’s hydroclimatic causes, frequency and severity, and producing reliable predictions are of critical importance for impact assessments, disaster mitigation, and future projection. This session invites contributions from all aspects of drought monitoring, diagnostics, prediction, and projection including (1) understanding the physical mechanism and manifestation of drought events, (2) estimation of drought frequency, spatial patterns, and intra-seasonal to inter-annual variability, (3) probabilistic and deterministic modeling and forecasting, (4) predictability of dynamic models and statistical methods in drought detection, (5) impacts of climate, landscape, and demand projections on the severity and frequency of future droughts, (6) drought indicators and assessment frameworks, and (7) diagnosis and attribution of drought events.
