Revisiting bare‐ground evaporation in a high‐resolution numerical weather prediction system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An improved method is proposed to parameterize evaporation in numerical weather prediction models. The figure shows dew‐point temperature forecast error (standard deviation of forecast error and bias) versus lead time over the North Plains region during spring 2022 for three parameterizations: CTL, the α$$ \alpha $$ method of Jacquemin and Noilhan; IFS:

The Mediterranean Extreme Events Experiment and storm Harry in January 2026

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This article introduces the Mediterranean Extreme Events Experiment (M3E) – a new project consisting of partners from Europe and the United States – whose main objective is to improve the weather forecasting of extreme events in the Mediterranean region via the deployment of drifting buoys with barometers (shown).

Satellite radiance observation error inflation and spatial thinning: Reconciling idealized theory with near‐operational applications

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Satellite radiance observations are spatially thinned using a grid‐based selection that retains one representative profile per cell. When observation errors are spatially correlated but treated as uncorrelated in the assimilation system, reducing thinning increases their influence, leading to overfitting and reduced analysis fit with other observations.

Design and Testing of a Minimal Configuration Underwater Micro‐Glider: Automating Lake and Reservoir Monitoring

Journal of Field Robotics, EarlyView.
ABSTRACT Uncrewed underwater vehicles (UUVs) have transformed oceanographic research through autonomous data gathering. Similarly, lake and other aquatic research can potentially be automated and transformed. However, UUVs would need to be smaller, lighter, less complex, and cheaper than currently available to make them more practical and user‐friendly

Vulnerability to Dams of the Last Undammed Large Rivers of Southeast Asia

River Research and Applications, EarlyView.
ABSTRACT The vast majority of large Eurasian rivers are regulated by hydropower dams, but some have survived as free‐flowing rivers so far in the Arctic and along stretches of the Myanmar coast. There, the Ayeyarwady (Irrawaddy) and Salween Rivers, two of the largest rivers of Southeast Asia, provide a huge amount of sediment, nurturing floodplains and

Historical remote sensing highlights long‐term persistence of Emperor Penguin (Aptenodytes forsteri) colonies

Remote Sensing in Ecology and Conservation, EarlyView.
Remote sensing can reveal population dynamics of Antarctic penguin colonies. In this study, we analyze emperor penguin (Aptenodytes forsteri) guano stains in remote sensing imagery and discover colony presence predating known records for 18 colonies across Antarctica.
