Characteristics for wind energy and wind turbines by considering vertical wind shear
Journal of Central South University, 2015The probability distributions of wind speeds and the availability of wind turbines were investigated by considering the vertical wind shear. Based on the wind speed data at the standard height observed at a wind farm, the power-law process was used to simulate the wind speeds at a hub height of 60 m.

Investigation of Horizontal and Vertical Wind Shear Effects Using a Wind Turbine Emulator
IEEE Transactions on Sustainable Energy, 2019This paper presents modeling and analysis of horizontal and vertical wind shear effects using a wind turbine emulator (WTE) with a comprehensive model. These periodic effects generate power fluctuations and mechanical stress on the wind turbine (WT) components during its operation.

Effect of vertical wind shear on flicker in wind farm
2013 IEEE Global Humanitarian Technology Conference: South Asia Satellite (GHTC-SAS), 2013Scarcity of electric power, in developing countries like India, demands more generation of electric power. The conventional means of generating power are much time consuming and hence it is necessary to utilize renewable energy sources like wind, solar etc. Wind is intermittent in nature.

On the Classification of Vertical Wind Shear as Directional Shear versus Speed Shear
Weather and Forecasting, 2006Abstract Vertical wind shear is commonly classified as “directional” or “speed” shear. In this note, these classifications are reviewed and their relevance discussed with respect to the dynamics of convective storms. In the absence of surface drag, storm morphology and evolution only depend on the shape and length of a hodograph, on ...

Statistics on Vertical Wind Shear over Oceans
Journal of Atmospheric and Oceanic Technology, 1984Abstract Statistics on boundary layer vertical wind shear were gathered from rawinsonde soundings taken from three small islands and one weather ship. These soundings show a high correlation between surface and 1829 m altitude wind directions. Wind speeds also were vertically correlated except at one tropical station where the winds were light.

Effects of Vertical Wind Shear
2011The effects of vertical wind shear on convective development have been examined for decades (e.g., Pastushkov 1975; Corbosiero and Molinari 2002; Lang et al. 2007; Ueno 2007). The delayed initiation of convection is associated with a strong vertical wind shear (e.g., Xu et al. 1992).

THE ROLE OF VERTICAL AND HORIZONTAL WIND SHEAR IN THE DEVELOPMENT OF QUASI-TROPICAL CYCLONES
Meteorologiya i Gidrologiya, 2023Cloud-resolving modeling has been implemented to investigate a lifecycle of two quasi-tropical cyclones (QTCs) over the Black and Mediterranean seas in September 2005 and 2018. The formation of the Mediterranean QTC under the influence of the PV streamer and the problems of predicting this phenomenon are considered.

Availability evaluation of wind farms considering the influence of vertical wind shear
Fifth Asia International Symposium on Mechatronics (AISM 2015), 2015The probability distribution of wind speed and availability of wind farms are investigated considering the vertical wind shear. Wind speed at extended height (60 m) was generated from that of reference height (10 m) through the Power-law Process. The least square (LS) method, maximum likelihood estimation (MLE) method and modified method are used to ...

Some Effects of Vertical Wind Shear on Thunderstorm Structure *
Bulletin of the American Meteorological Society, 1949Observations of thunderclouds obtained with a 3-cm height-finding radar set are used to obtain a description of the vertical shear of thunderclouds. Several photographs are given which show the shearing of the radar clouds. A scattergram of wind shear plotted against echo shear is presented and shows that the two variables are related, with the former ...

Climatology of Vertical Wind Shear over the Tropical Atlantic
Journal of Climate, 2006Abstract The spatiotemporal variability of the 200–850-hPa vertical wind shear over the tropical Atlantic is examined for a period of 46 yr. This work extends and updates past studies by considering a longer data record as well as a tropospheric-deep measure of vertical wind shear.
