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.

Effect of vertical wind shear on the growth of convective clouds
Quarterly Journal of the Royal Meteorological Society, 1967AbstractThe relationship between vertical wind shear and the vertical extent of convective clouds is examined. In order to take into consideration the movement of the cloud, a ‘Relative Top Shear’ (RTS) is defined. Radar data and upper winds at some Indian stations in different seasons have been studied and a comparison made between RTS at different ...

Vertical wind shear measurements in the lower stratosphere
Quarterly Journal of the Royal Meteorological Society, 1975AbstractDuring 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.

Effects of Vertical Wind Shear on Tropical Cyclone Precipitation
Monthly Weather Review, 2010Abstract 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 ...

Effects of Vertical Wind Shear on the Predictability of Tropical Cyclones
Journal of the Atmospheric Sciences, 2013Abstract Through cloud-resolving simulations, this study examines the effect of vertical wind shear and system-scale flow asymmetry on the predictability of tropical cyclone (TC) intensity during different stages of the TC life cycle.

The effects of vertical wind shear on the evolution of convective clouds
Quarterly Journal of the Royal Meteorological Society, 1975AbstractThe effects of ambient wind shear Uo on the evolution of an isolated three‐dimensional convective cloud are studied. Sixteen cases are considered which differ from one another both in the value of U′0 in the initial value of the energy of atmospheric instability per unit height of the unstable layer, E0.

On the frictional influence of horizontal wind shear on vertical motion
Quarterly Journal of the Royal Meteorological Society, 1946AbstractIt is suggested that a reason for the association between anticyclonic vorticity and subsidence lies in the divergence produced by the frictional forces when a strong horizontal wind shear is present. In particular the region just to the south of a strong westerly upper wind (northern latitudes) is favourable for subsidence.A case in which such

Vertical Axis Wind Turbine Operational Modal Analysis in Sheared Wind Flow
2012There 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.

The Effects of Vertical Wind Shear on the Distribution of Convection in Tropical Cyclones
Monthly Weather Review, 2002Abstract The influence of vertical wind shear on the azimuthal distribution of cloud-to-ground lightning in tropical cyclones was examined using flash locations from the National Lightning Detection Network. The study covers 35 Atlantic basin tropical cyclones from 1985–99 while they were over land and within 400 km of the coast over water.
