Quantifying and Classifying Non‐Stationary Turbulence Under Sub‐Mesoscale Disturbances

Geophysical Research Letters
Non‐stationary turbulence induced by sub‐mesoscale disturbances can substantially bias flux estimates, yet is largely overlooked in existing evaluation frameworks.

Turbulence intensity footprints of built and natural environment as measured by anemometers at Hong Kong International Airport

Meteorologische Zeitschrift, 2022
Terrain and building-induced low-level turbulence is studied in this paper. Data from six anemometers, respectively along the North and South Runways of Hong Kong International Airport, are analysed over the period of 2012 to 2018.

Computational Fluid Dynamics (CFD) Investigation of Wind Turbine Nacelle Separation Accident over Complex Terrain in Japan

Energies, 2018
We have developed an unsteady and non-linear wind synopsis simulator called RIAM-COMPACT (Research Institute for Applied Mechanics, Kyushu University, COMputational Prediction of Airflow over Complex Terrain) to simulate the airflow on a micro scale, i.e.

Estimation of orographically induced wave drag in the stable boundary layer during the CASES-99 experimental campaign [PDF]

, 2009
This paper addresses the quantification of gravity wave drag due to small hills in the stable boundary layer. A single column atmospheric model is used to forecast wind and temperature profiles in the boundary layer.
