Wind, Wind Speed,

u & v Flux, Surface stress velocity
Definition
Air in motion relative to the surface of the
Earth.
Since vertical components of atmospheric motion are relatively small,
especially near the surface of the earth, meteorologists use the term to
denote almost exclusively the horizontal component. Meridional flow is the
atmospheric flow in which north south component (i.e. longitudinal, or along a
meridian) is pronounced relative to the zonal (east-west) component.
The equatorial easterlies, tropical (trade winds) and polar
easterlies blow from the east. The westerlies represent the dominant
west-to-east motion of the atmosphere centered over the 35-65 degree latituded
bands of both hemispsheres.
