Availability evaluation of wind farms considering the influence of vertical wind shear

Fifth Asia International Symposium on Mechatronics (AISM 2015), 2015
The 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 ...

Effects of Vertical Wind Shear on Tropical Cyclone Precipitation

Monthly Weather Review, 2010
Abstract The response of the precipitation field for tropical cyclones in relation to the surrounding environmental vertical wind shear has been investigated using ∼20 000 snapshots of passive-microwave satellite rain rates. Composites of mean rain rates, 95th percentile rain rates, and rain coverage were constructed to compare how the ...

Some Effects of Vertical Wind Shear on Thunderstorm Structure *

Bulletin of the American Meteorological Society, 1949
Observations 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 ...

Vertical wind shear measurements in the lower stratosphere

Quarterly Journal of the Royal Meteorological Society, 1975
AbstractDuring two flight series of superpressure constant‐level balloons conducted in the lower stratosphere by the Laboratoire de Météorologie Dynamique, the vertical wind shear vector over 100 metres has been measured. It has been found from a record of almost two months that the r.m.s. wind shear is about 1·5 × 10−2s−1.

Vertical Wind Shear Associated with Left-Moving Supercells

Weather and Forecasting, 2002
Vertical wind shear parameters are presented for 60 left-moving supercells across the United States, 53 of which produced severe hail ($1.9 cm). Hodographs corresponding to environments of left-moving supercells have a tendency to be more linear than those of their right-moving supercell counterparts.

Wind turbine wake vertical distributions considering different inflow shear indices

International Conference on Renewable Power Generation (RPG 2015), 2015
Wind shear inflow conditions with different indices lead to different wind speed distributions in wind turbine wakes, which further affects the power output of downstream turbines. In this study we focus on wind turbine wake considering different inflow shear indices.

Vertical Axis Wind Turbine Operational Modal Analysis in Sheared Wind Flow

There has been increased interest in implementing co-located renewable energy generation systems in urban areas, and vertical axis wind turbines (VAWTs) are a candidate technology for capturing the unsteady, omnidirectional winds that are typical of an urban environment.

Asymmetric Wind Expansion of an Idealized Simulated Tropical Cyclone by Vertical Wind Shear

Journal of the Atmospheric Sciences
Abstract This study investigates the impact of vertical wind shear (VWS) on vortex size expansion using a series of idealized numerical experiments. A control experiment (CTL) without ambient flow is compared with the experiments with 6 m s −1 (SH6) and 12 m s

Impacts of Vertical Wind Shear on Mesoscale Topographical Convective Precipitation

Chinese Journal of Geophysics, 2012
AbstractIn this study, a set of idealized three‐dimensional numerical simulations with mesoscale models are designed to study the impacts of vertical wind shear upon the topographically convective precipitation based on the mesoscale features of topography in the middle‐lower reaches of the Yangtze River and the main characteristics of vertical wind ...
