Evaluating the Effect of Turbulence on Aircraft During Landing and Take-Off Phases

International Journal of Aviation, Aeronautics, and Aerospace, 2018
—— Low level wind shear and turbulence present a serious safety risk to aircraft during the approach, landing and take-off phases. Low level wind shear has been identified as one of the primary factors for aircraft go-arounds and aborted landings. During

The Influence of Vertical Wind Shear on Moist Thermals

Journal of the Atmospheric Sciences, 2019
Although it is well established that vertical wind shear helps to organize and maintain convective systems, there is a longstanding colloquial notion that it inhibits the development of deep convection.

Wind shear estimation model using load measurement of wind turbine tower and surrogate model

Wind Energy, 2020
A wind shear estimation method based on fore‐aft moment is proposed to estimate wind shear strength without a Doppler lidar. We construct wind shear estimation models (WSEMs) using surrogate models whose input is the time‐averaged fore‐aft moment and ...
