Wind shear at the blades nearest to the ground level compared to those at the top of blade travel, and this in turn affects the turbine operation. This low level wind shear can create a large bending moment in the shaft of a two bladed turbine when the blades are vertical. The reduced wind shear over water means shorter and less expensive wind turbine towers can be used in shallow seas. Wind shear Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear
