Today’s Highlights
A single but impactful study from Geophysical Research Letters examines hydrologic whiplash — rapid transitions between high and low streamflow — in the Mississippi River Basin. Using CESM2 Large Ensemble projections under SSP3-7.0, the authors find dramatic increases in whiplash frequency on western tributaries, with the Missouri (+115%) and Arkansas (+137%) rivers most affected. The work reveals that antecedent precipitation and snowmelt pulses initiate these events, while soil moisture anomalies play a contrasting role compared to isolated extreme events.

Volatility and unpredictability of hydroclimate systems stresses planning and risk management. Notably, the rapid transition between periods of high and low streamflow, known as hydrologic whiplash, is gaining attention worldwide. Yet the specific mechanisms driving hydrologic whiplash events, and how they differ from singular events, remain poorly understood. We examine whiplash within the Mississippi River basin using observations and the Community Earth System Model version 2 Large Ensemble (CESM2‐LENS) to quantify historic occurrence on major tributaries and changes in frequency through the 21st century under a moderately high emissions scenario (SSP3‐7.0), and identify hydrologic mechanisms distinguishing these events from isolated events. We find that whiplash events increase in frequency most notably on western tributaries (Missouri, +115% and Arkansas, +137%), and that antecedent precipitation and snowmelt pulses or deficits initiate these whiplash events, while soil moisture anomalies can have opposite signs from those associated with singular events.
