VADVelocity Azimuth DisplayVAD Wind ProfileA radar plot of horizontal winds, derived from VAD data, as a function of height above a Doppler Radar. The display is plotted with height as the vertical axis and time as the horizontal axis (a so-called time-height display), which then depicts the change in wind with time at various heights. This display is useful for observing local changes in vertical wind shear, such as backing of low-level winds, increases in speed shear, and development or evolution of nearby jet streams (including low-level jets). This product often is referred to erroneously as a VAD.Vadose ZoneThe locus of points just above the water table where soil pores may either contain
air or water. This is also called the zone of aeration
