VAD
Wind
Profile. A 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 .
