Directional wind wave development

Geophysical Research Letters, 1994
Using aircraft radar instruments designed for sea surface wave measurements, we have obtained fetch‐limited directional wind wave spectra under steady off‐shore wind conditions. The results from these observations in different areas at different times show that, up to a fetch of 150 km, the dominant waves propagate at an angle to the wind. The angle is

Increased power gains from wake steering control using preview wind direction information [PDF]

Wind Energy Science, 2023
Yaw controllers typically rely on measurements taken at the wind turbine, resulting in a slow reaction to wind direction changes and subsequent power losses due to misalignments.

Joint segmentation of wind speed and direction using a hierarchical model [PDF]

, 2007
The problem of detecting changes in wind speed and direction is considered. Bayesian priors, with various degrees of certainty, are used to represent relationships between the two time series.

Numerical Simulation on Wind Speed Amplification of High-Rise Buildings with Openings

Atmosphere, 2023
To explore the influence of openings on wind loads and wind speeds in high-rise buildings, the wind flow around three-dimensional (3D) square cylinders with a breadth/height aspect ratio of 1:6 was numerically simulated using the large eddy simulation ...

A Novel Integrated Algorithm for Wind Vector Retrieval from Conically Scanning Scatterometers

Remote Sensing, 2013
Due to the lower efficiency and the larger wind direction error of traditional algorithms, a novel integrated wind retrieval algorithm is proposed for conically scanning scatterometers. The proposed algorithm has the dual advantages of less computational

On the shape of barchan dunes

, 2005
Barchans are crescent-shaped sand dunes forming in aride regions with unidirectional wind and limited sand supply. We report analytical and numerical results for dune shapes under different environmental conditions as obtained from the so-called `minimal
