Aerosol Impacts on Mesoscale Convective Systems Forming Under Different Vertical Wind Shear Conditions

open access: yesJournal of Geophysical Research - Atmospheres, 2020
Following our previous study of wind shear effect on mesoscale convective system (MCS) organization under a clean atmospheric condition using the Weather Research and Forecasting model coupled with spectral‐bin microphysics, we conduct sensitivity ...

From shear to veer: theory, statistics, and practical application [PDF]

open access: yesWind Energy Science, 2023
In the past several years, wind veer – sometimes called “directional shear” – has begun to attract attention due to its effects on wind turbines and their production, particularly as the length of manufactured turbine blades has increased.

Some observations of low level wind shear at the Hong Kong International Airport in association with tropical cyclones

open access: yesMeteorological Applications, 2020
In summer, Hong Kong is affected by tropical cyclones moving northwestwards over the northern part of the South China Sea. They may bring strong southeasterly airflow to the territory.

Development of an Advanced Fluid-Structure-Acoustics Framework for Predicting and Controlling the Noise Emission from a Wind Turbine under Wind Shear and Yaw

open access: yesApplied Sciences, 2020
Noise generated from wind turbines is a big challenge for the wind energy industry to develop further onshore wind energy. The traditional way of reducing noise is to design low noise wind turbine airfoils and blades.

Characterization of offshore vertical wind shear conditions in Southern New England

open access: yesWind Energy, 2020
Vertical wind shears could have a significant effect on the energy produced by a wind turbine and on its loads. Although the development of several wind farms has been planned on the East Coast of the United States, there are no studies that characterize

Study on the influence of topography on wind shear numerical simulations based on WRF–CALMET [PDF]

open access: yesGeoscientific Instrumentation, Methods and Data Systems
This study focuses on the critical issue of low-altitude wind shear, which is vital for aircraft safety during takeoff and landing. Using the WRF–CALMET model, we assess the impact of topography on low-level wind shear at Zhongchuan Airport.

Hong Kong Airport Wind Shear Now-Casting System Development and Evaluation

open access: yesAtmosphere, 2022
A wind-shear now-casting system for Hong Kong International Airport is described. The system has been configured and run retrospectively for the period from January to April 2018 at 20-min intervals using two sets of meteorological inputs to quantify ...

Identification and Forecasting of Typical Wind Shear and Shear Line Based on Two‐Dimensional Wind Field

open access: yesMeteorological Applications
The forecasting of clear‐air wind shear presents a significant challenge in aviation meteorology. To improve the accuracy of wind shear identification and forecasting using coherent Doppler wind lidar, this study proposes an advanced method for ...

Windshear Identification Algorithms by Doppler Pulse Lidar [PDF]

open access: yesITM Web of Conferences, 2019
Doppler pulse lidars are increasingly common as a tool for monitoring hazardous wind phenomena. Possible applications include measurements of wake vortices behind aircraft, detection of vertical and horizontal wind shear, detection of gust fronts, and ...

Implementation of large-scale average geostrophic wind shear in WAsP12.1 [PDF]

open access: yes, 2018
The vertical extrapolation model described in the European Wind Atlas Troen and Petersen (1989) is modified to take into account large-scale average geostrophic wind shear to describe the effect of horizontal temperature gradients on the geostrophic wind.
