A cyclo-stationary complex multichannel wiener filter for the prediction of wind speed and direction [PDF]

open access: yes, 2013
This paper develops a linear predictor for application to wind speed and direction forecasting in time and across different sites. The wind speed and direction are modelled via the magnitude and phase of a complex-valued time-series.

Copula‐based joint distribution analysis of wind speed and wind direction: Wind energy development for Hong Kong

open access: yesWind Energy, 2023
Accurate and reliable assessment of wind energy potential has important implication to the wind energy industry. Most previous studies on wind energy assessment focused solely on wind speed, whereas the dependence of wind energy on wind direction was ...

PCA analysis of wind direction climate in the baltic states

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2021
Wind direction is one of the fundamental parameters of weather. In this study we investigate the wind direction climate 10 m above surface level in the Baltic States (Estonia, Latvia, Lithuania).

Study on Wind Field Characteristics in a Coastal Plain Based on a New Three-Dimensional Joint Distribution Model

open access: yesApplied Sciences, 2021
This paper studied the joint probability distribution of wind speed, wind direction, and wind height. The measured wind field data of a coastal plain in Zhongshan city, Guangdong Province, China, were taken as the research object.

Wind Direction Retrieval Using Spaceborne GNSS-R in Nonspecular Geometry

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
A wind direction retrieval algorithm using spaceborne global navigation satellite system reflectometry (GNSS-R) in nonspecular geometry is presented. This article first focuses on investigating the influence of wind direction on the scattering strength ...

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

open access: yes, 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.

Research on Wind Field Characteristics Measured by Lidar in a U-Shaped Valley at a Bridge Site

open access: yesApplied Sciences, 2021
Currently, research on wind fields of U-shaped valleys is rarely reported, and anemometers or wind observation towers are usually used for field measurement, but the measured position is limited and the cost is high.

Domestic Wind Energy Planning for Deprived Communities in the Tropics: A Case Study of Nigeria

open access: yesInternational Journal of Renewable Energy Development, 2023
Despite the notable inventions in solar energy, it is still too high for standalone users from developing countries. For example, it cost $2200 to provide power for a two-bedroom apartment while the average citizen lives below the country’s poverty line ...
