In common usage, wind gradient, more specifically wind speed gradient or wind velocity gradient, or alternatively shear wind, is the vertical gradient of the mean horizontal wind speed in the lower atmosphere. It is the rate of increase of wind strength with unit increase in height above ground level. In metric units, it is often measured in units of meters per second of speed, per kilometer of height (m/s/km), which reduces to the standard unit of shear rate, inverse seconds (s−1).

Famous quotes containing the word wind:
“I say this because there is an uneasiness in things just now. Waiting for something to be over before you are forced to notice it. The pollarded trees scarcely bucking the wind and yet it’s keen, it make you fall over. Clabbered sky. Seasons that pass with a rush.”
—John Ashbery (b. 1927)
