Update of upper level turbulence forecast by reducing unphysical components of topography in the numerical weather prediction model

Geophysical Research Letters, 2016
On 2 November 2015, unrealistically large areas of light‐or‐stronger turbulence were predicted by the WRF‐RAP (Weather Research and Forecast Rapid Refresh)‐based operational turbulence forecast system over the western U.S. mountainous regions, which were

Stably stratified canopy flow in complex terrain [PDF]

Atmospheric Chemistry and Physics, 2015
Stably stratified canopy flow in complex terrain has been considered a difficult condition for measuring net ecosystem–atmosphere exchanges of carbon, water vapor, and energy.

Local law-of-the-wall in complex topography: a confirmation from wind tunnel experiments [PDF]

, 2001
It is well known that in a neutrally-stratified turbulent flow in a deep constant-stress layer above a flat surface, the variation of the mean velocity with respect to the distance from the surface obeys the logarithmic law (the so-called ``law-of-the ...

High‐resolution simulation of a severe case of low‐level windshear at the Hong Kong International Airport: Turbulence intensity and sensitivity to turbulence parameterization scheme

Atmospheric Science Letters, 2022
Large eddy simulations are performed for a severe windshear case of terrain‐induced airflow disturbances at the Hong Kong International Airport. The objectives of the study include: (i) to investigate the performance of large eddy simulation in capturing

Earth’s polar night boundary layer as an analogue for dark side inversions on synchronously rotating terrestrial exoplanets [PDF]

, 2020
A key factor in determining the potential habitability of synchronously rotating planets is the strength of the atmospheric boundary layer inversion between the dark side surface and the free atmosphere.

Field experimental study of traffic-induced turbulence on highways [PDF]

, 2012
This paper is focused on traffic-induced turbulence (TIT) analysis from a field campaign performed in 2011, using ultrasonic anemometers deployed in the M-12 Highways, Madrid (Spain). The study attempts to improve knowledge about the influence of traffic-

Accelerated impact of airborne glaciogenic seeding of stratiform clouds by turbulence [PDF]

Atmospheric Chemistry and Physics
Several recent studies have reported complete cloud glaciation induced by airborne-based glaciogenic cloud seeding over plains. Since turbulence is an important factor controlling mixed-phase clouds, including ice initiation, snow growth, and cloud ...

Impact of Negative Geostrophic Wind Shear on Wind Farm Performance

PRX Energy, 2022
Baroclinicity, which leads to height-dependent driving pressure gradients, occurs in various situations such as the flow transition between land and sea, and sloping terrain.
