Observations and numerical simulations of a valley‐exit wind in the Alpine Bolzano basin

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The evolution and spreading of the nocturnal valley‐exit wind flowing from the Isarco Valley into the Bolzano basin, in the Italian Alps, are found to be influenced by the basin temperature stratification. Measurements and high‐resolution simulations show that a cold‐air pool favors an upward trajectory of the flow at the exit of the valley.

AIRFLOW: An End-to-End Spatial–Channel Cross Attention Framework for Real-Time Passenger Detection and Tracking

IEEE Access
Real-time passenger detection and tracking in transportation environments presents significant challenges due to complex backgrounds, varying lighting conditions, dense crowds, and severe occlusions.

Numerical simulation and physical understanding of a locally initiated sea fog event over the eastern Yellow Sea with a transition of air–sea temperature difference

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Unexpected sea fog in the west coast of South Korea had a huge impact on the transportations in the Seoul–Incheon metropolitan area. We reproduced successfully the formation and evolution of a sea event with a transition of air–sea temperature difference using the Weather Research and Forecasting model.

Real-Time Pedestrian Detection and Multi-Object Tracking in Complex Airport Scenes via Frequency-Aware and Mamba-Enhanced Representation

IEEE Access
Real-time pedestrian detection and multi-object tracking (MOT) in complex airport surveillance scenarios present significant challenges, including drastic scale variation, frequent occlusion, cluttered backgrounds, and diverse motion dynamics.

The evaluation of boundary‐layer turbulence in high‐resolution numerical weather prediction simulations using Doppler lidar

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A new method compares both kilometer and sub‐kilometre weather model simulations with Doppler lidar observations to assess the representation of boundary‐layer turbulence. While bulk boundary‐layer properties are well represented, vertical velocity variance is strongly underestimated in both simulations.

Research on the Efficiency of Major Airports in China’s Six Major Airport Cluster: Based on Common Frontier Super-Efficiency DEA and Malmquist Method

Promet (Zagreb)
Airport clusters are of great significance to the sustainable development of the civil aviation transportation industry. The study utilises common frontier and super-efficiency DEA methods to assess the efficiency of China’s six major airport groups.

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.

Three‐Year Propagation Experiment at Ku‐, Ka‐, and Q‐Band in French West Indies

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT From January 2021 to December 2023, the Office National d'Etudes et de Recherches Aérospatiales (ONERA) and the Centre National d'Etudes Spatiales (CNES) conducted a three‐year Earth‐space propagation measurement campaign in Guadeloupe. The experiment used beacon receivers deployed in Pointe‐à‐Pitre airport to record signals at 11.2, 19.7, and
