How does vertical wind shear influence entrainment in squall lines?

, 2021
The influence of vertical wind shear on updraft entrainment in squall lines is not well understood. To address this knowledge gap, a suite of high-resolution idealized numerical model simulations of squall lines were run in various vertical wind shear ...

Wind Shear of Low-Level Jets and Their Influence on Manned and Unmanned Fixed-Wing Aircraft during Landing Approach

Atmosphere, 2021
Wind shear at low altitudes represents a potential hazard to landing aircraft. Based on two wind lidar data sets of one year, the occurrence of low-level jets (LLJs), the vertical wind shear and the rotation of the wind direction were analysed. The lidar

Performance of large-eddy simulations for capturing low-level wind shear at the Hong Kong International Airport for a whole wind-shear (spring) season

Meteorologische Zeitschrift, 2023
The wind-shear reports from pilots from a particular springtime wind-shear season at the Hong Kong International Airport, namely, January to April 2021, are considered in order to study the performance of a meteorological model in large-eddy simulations ...

The Impacts of Wind Shear on Spatial Variation of the Meteorological Element Field in the Atmospheric Convective Boundary Layer Based on Large Eddy Simulation

Atmosphere, 2022
As wind shear increases, the quasi-two-dimensional structure of flows becomes more significant in the convective boundary layer (CBL), indicating that wind shear plays an essential role in the variation of the field of atmospheric flow.

Impact of Negative Geostrophic Wind Shear on Wind Farm Performance

PRX Energy, 2022
Baroclinicity, which leads to height-dependent driving pressure gradients, occurs in various situations such as the flow transition between land and sea, and sloping terrain.
