What units are used to report vertical wind shear?
  • A
  • B
    kt/100 ft.
  • C
  • D
    m/100 ft

WIND SHEAR is a sudden change in wind direction and/or speed over a very short distance. We can think of wind shear as a gradient in wind velocity that can be interpreted in the same way as a pressure or temperature gradient.

Wind shear can be broken up into two parts:

  • Horizontal wind shear - A change in the wind over a horizontal distance. Measured in knots/1 000 ft.
  • Vertical wind shear - A change in speed and/or direction with change of height. Measured in knots/100 ft.
