Assessing high‐resolution numerical models and bottom‐boundary factors for a Mediterranean heavy precipitation event

Quarterly Journal of the Royal Meteorological Society, EarlyView.
State‐of‐the‐art, convection‐permitting NWP models reproduced the main features of the October 22–23, 2019 heavy precipitation event in Catalonia. However, slight configuration changes yielded varying streamflow responses and statistical performance, highlighting the challenge of simulating these events in Mediterranean medium‐sized basins ...

Modulation of North Atlantic atmospheric rivers by the Gulf Stream

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Gulf Stream ocean variability plays a key role in modulating atmospheric river (AR) activity over the North Atlantic during winter and spring at monthly time‐scales. Increased ocean heat transport and mesoscale activity in the Gulf Stream are linked to northward shifts in ARs, while stronger surface heat fluxes drive ARs southward.

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

River Research and Applications, EarlyView.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Propagation patterns of hydrological droughts in the source region of Yellow River: Insights from standardized versus threshold‐based approaches

River, EarlyView.
Abstract Understanding the propagation patterns of hydrological droughts is crucial for drought prevention, disaster mitigation, and water resource management. Two common methodological frameworks are employed: standardized indices, represented by the Standardized Streamflow Index (SSI), and threshold‐based (non‐standardized) indices, represented by ...
