Impact of Weak‐Constraint Four‐Dimensional Variational data assimilation on the prediction of a sudden stratospheric warming event in 2024

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The Weak‐Constraint Four‐Dimensional Variational (WC‐4DVAR) system markedly improved the analysis and forecasting of the 2024 sudden stratospheric warming (SSW) event. It reduced biases and enhanced 7–9 day predictions of temperature across the SSW life cycle, with the most pronounced gains for winds also during the critical onset period.

The physical and synoptic‐dynamical differences between warm days, hot days, and heatwaves during summer in Victoria, Australia

Quarterly Journal of the Royal Meteorological Society, EarlyView.
During the day, there is composite mean cold advection in the boundary layer on warm days (WDs), hot days (HDs) and heatwaves (HWs). There is weaker surface‐sensible heating on HDs and HWs. A nocturnal jet advects warm air on HDs and HWs. There is a strong and slow‐moving upper‐level anticyclone on HWs.

Riparian Failure: Damming and Flow Stabilization Exclude Cottonwood Colonization Along a Dryland River

River Research and Applications, EarlyView.
ABSTRACT The Marias River flows from Glacier National Park through northcentral Montana, and into the Missouri River. Annual flows gradually declined from 1902 to 2024 (~3.2%/decade) and the 1952 Tiber Dam and Lake Elwell reservoir were operated to attenuate peak flows and stabilize downstream flows year‐round.

Impact of the Addition of a Shading Algorithm in a Physically Based Conceptual River Hydrological–Temperature Model

River Research and Applications, EarlyView.
ABSTRACT Anthropogenic impacts on the thermal regime of rivers include climate change and deforestation. For the latter, developing modelling tools that can account for the impact of varying vegetation cover on river temperatures is essential. This study describes a new addition to the CEQUEAU hydrological and water temperature model: a shading ...
