Mesoscale Model Forecast Skill for Hourly Rainfall During Postfire Flood and Debris-Flow Events in California

This study evaluates the performance of WestWRF and HRRR mesoscale weather models in forecasting hourly rainfall triggering postfire debris flows in California, finding that while both models reliably predict the occurrence of threshold rainfall within 24 hours, they consistently underestimate the intensity of extreme events.

Soil amelioration driven by diverse Herbaceous perennials cultivation: Responses of physicochemical properties, enzyme activities, and organic carbon

This study demonstrates that cultivating diverse herbaceous perennials in Northeast China significantly improves soil physicochemical properties, with *Pseudolysimachion spicatum* identified as the most effective species for enhancing soil aggregate stability, nitrogen availability, and microbial biomass carbon.

Vegetation recovery predicts soil carbon storage despite 350 years of metal-smelting legacies

This study demonstrates that in forests affected by 350 years of metal smelting, soil carbon storage is primarily predicted by the recovery of bryophyte-dominated vegetation and depth-organized nitrogen cycling rather than by the distance from the source or the remaining metal contamination levels.

Evolution of Boreal-Summer Quasi-Stationary Rossby Waves on Daily Time Scales

This study reveals that quasi-stationary Rossby waves, typically identified in seasonal-mean fields, also manifest as coherent daily-to-subseasonal events characterized by a distinct life cycle where wave centers remain longitudinally stable while their phase lines systematically rotate due to poleward variations in phase speed.

The Social Vulnerability Index and Exposure to Heat in California Census Tracts

This study of California census tracts reveals that while the CDC/ATSDR Social Vulnerability Index is widely used for climate policy, it shows only a weak overall spatial correlation with heat exposure, with significant variations depending on specific subregions and latent class groupings.

Direct tsunami wavefield sensing on submarine telecom cables enables coastal wave height forecasting

This study demonstrates that distributed acoustic sensing on existing submarine telecom cables can detect minute open-ocean tsunami signals, enabling the reconstruction of wavefields and the provision of 5 to 15 minutes of early warning for coastal impacts.
