Definition of wind shear in English:

wind shear

noun

  • [mass noun] Variation in wind velocity occurring along a direction at right angles to the wind's direction and tending to exert a turning force.

    • ‘Windsocks can also be good indicators of wind shear and turbulence.’
    • ‘Although the preponderance of thunderstorm effects are found directly under the storm, hail and wind shear have been documented more than 20 miles away.’
    • ‘Winds blowing in different directions, or at different speeds create what meteorologists call wind shear.’
    • ‘The atmospheric flow will also have an influence, as strong vertical wind shear can inhibit cyclogenesis (spawning of cyclones).’
    • ‘If you talk to the licensing or regulatory organizations, crosswind is a licensing issue, but turbulence or and wind shear is not an issue through which an airport can be condemned or denied a license.’
    • ‘In recent years, the term wind shear has often been used for only one kind of wind shear; the winds that blast down from thunderstorms.’
    • ‘Thunderstorms present aviators with many meteorological hazards: extreme turbulence and icing, low-level wind shear, microbursts, lightning strikes, and hail.’
    • ‘Its power is diminished by cooler water and upper level winds - known as wind shear - that can hinder the storm's development or tear it apart.’
    • ‘Of course strong wind shear at high altitude can cause problems.’
    • ‘Scientists believe that these variations may arise from significant vertical wind shear.’
    • ‘Near the ground, thunderstorms sometimes create quick changes in wind speed and direction, called wind shear, which has caused several crashes.’
    • ‘With the temperatures normally increasing throughout the day, what would be a benign canyon in the calm, early-morning air could be filled with dangerous up and down drafts, turbulence and wind shear by afternoon.’
    • ‘Reinforced concrete core walls linked to the exterior columns of the building will help, providing both resistance to wind shear and seismic forces.’
    • ‘Decreased wind shear - upper-level winds that can disrupt hurricane formation - would lead to more and stronger hurricanes.’
    • ‘Also, upper level winds - known as wind shear - can tear apart developing hurricanes.’
    • ‘If a tilt is created in these drafts by wind shear, additional up or downdrafts can occur and this can result in extra cells being formed.’
    • ‘Hurricane Rita's intensification also was aided by the fact that there are no upper-level winds - known as wind shear - to tear the storm apart or hinder its development, Beeler said.’
    • ‘Slow the airplane to reduce impact forces; also, you'll likely encounter wind shear and strong downdrafts.’
    • ‘Textbook orthodoxy had long excluded the possibility of such an event - sea temperatures, experts claimed, are too low and wind shear too powerful to allow tropical depressions to evolve into cyclones south of the Atlantic Equator.’
    • ‘We were then introduced to a little known (at that time) atmospheric phenomenon called wind shear.’
