CONVECTIVE VELOCITY SCALE (w*)
Field observations, laboratory experiments, and numerical modeling studies show that the large turbulent eddies in the CBL have velocities proportional to the convective velocity scale ( w*) (Wyngaard, 1988). Thus in order to estimate turbulence in the CBL, an estimate of , w* is needed. AERMET calculates the convective velocity scale from its definition (see Wyngaard, 1988) as:
