Bridge vibration under complex wind field and corresponding measurements: A review

Journal of Traffic and Transportation Engineering (English ed. Online), 2022
Due to increased demands in transportation development, bridge construction has been extended to areas with complex wind fields. In addition to common flow features such as high wind speeds and strong turbulence intensity, in coastal areas, bridges are ...

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.

Dynamical age of solar wind turbulence in the outer heliosphere

, 1998
In an evolving turbulent medium, a natural timescale can be defined in terms of the energy decay time. The time evolution may be complicated by other effects such as energy supply due to driving, and spatial inhomogeneity.

A framework to evaluate and identify development requirements for land‐surface models at km‐scale resolution: Application to a semi‐arid and mountainous region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This article provides a first evaluation of land‐surface models at the km‐scale resolutions at which they are used in weather and Earth‐system models. At these resolutions, the lateral transfers of water that organize landscapes play an important role in predicting evaporation correctly. Riparian processes and human water management for irrigation need

Impacts to the mountain‐valley circulation from the 2023 annular solar eclipse

Weather, EarlyView.
In October 2023, as part of the Nationwide Eclipse Ballooning Project (NEBP), faculty and students from the University of North Dakota (UND) in coordination with Pueblo Community College Southwest collected weather observations during an annular solar eclipse colloquially known as a ‘ring of fire’ eclipse.

Machine learning application and operational strategy for global low-level aviation turbulence forecasting

npj Climate and Atmospheric Science
Low-level turbulence (LLT), primarily driven by terrain-induced and convective processes, remains a critical hazard to aviation safety. This study establishes the applicability of machine-learning to global LLT forecasting below 10,000 ft, alongside the ...

Surface Morphology Effects on Turbulent Structure and Diffusion Across Multiple Underlying Surfaces in a Wind Tunnel

Applied Sciences
Turbulent structure and diffusion over different underlying surfaces are fundamental to understanding mass and momentum exchange in the atmospheric boundary layer. This study investigated these processes over six distinct surfaces—flat plate, sand, grass,
