Today’s Highlights
Two Geophysical Research Letters papers tackle the future of extreme hydrology under climate change. Bae et al. introduce a semi-parametric framework with a bounded logistic link function that prevents unrealistic flood estimates in climate-informed frequency models, demonstrating improved stability across 548 CONUS basins. Leake et al. use convection-permitting simulations at 3.75 km resolution to show that US sub-daily precipitation will become more polarized — with heavy events intensifying (>100% increase in the Northwest) while lighter events decrease 10–40% — a redistribution that will strain water infrastructure and management planning.

On the Stability and Sensitivity of Climate‐Informed Flood Frequency Models
Authors: Kichul Bae, Jeongwoo Hwang, Chandramauli Awasthi, Arumugam Sankarasubramanian

Matched topics: flood, climate change
Reliable flood change projections under climate change are critical for water resources planning yet remain challenging due to uncertainty in climate‐informed statistical models. Conventional approaches relate flood distribution parameters to climate variables using log‐linear formulations, which can produce unrealistically large flood estimates. In this study, we develop a semi‐parametric statistical framework that constrains flood variability using a bounded logistic link function and estimates parameters from hydroclimatically analogous samples. Using 548 natural basins across the coterminous United States, we evaluate the proposed approach against log‐linear formulations from the entire sample. Model performances are assessed based on both the accuracy and sensitivity of flood quantiles to climate forcings. Results show that the proposed framework yields more stable and realistic flood quantile estimates, particularly under high precipitation conditions, and better preserves flood sensitivity. These findings highlight the value of bounded, locally informed statistical models for robust flood risk assessment under climate change.
Distributions of Short‐Duration High‐Intensity Precipitation Events in the United States Under Intermediate and Pessimistic Climate Change Scenarios

Journal: Geophysical Research Letters · DOI: 10.1029/2026gl122710
Matched topics: water management, seasonal, climate change
Under a warming climate, the magnitude and frequency of intense precipitation are expected to increase globally, on average. However, changes in the regional variability of short‐duration high‐intensity (SDHI) precipitation across the contiguous United States—both temporally and spatially—remain uncertain, and most projections rest on resolutions too coarse to resolve the responsible processes. Herein, convection‐permitting, dynamically downscaled simulation output at 3.75 km grid spacing and 15‐min intervals is used to examine potential changes in the occurrence, accumulation, and magnitude of sub‐daily precipitation relative to simulated historical levels. Changes are concentrated at both tails of the intensity distribution: precipitation at or above the 99th percentile increases significantly in five of seven regions, exceeding 100% in the Northwest, while lighter intensities decrease by 10%–40%. These changes are regionally and seasonally concentrated rather than uniform, and their dependence on accumulation duration varies by region, so future hydroclimates may be characterized by fewer light‐to‐moderate events punctuated by more intense ones, a redistribution that will challenge water management and infrastructure design.
