The latter criterion typically is associated with a minimum single-Doppler velocity differential of 22-30 m s^sup -1^ across the mesocyclone/mesoanticyclone. [...] the observed velocity differential or tangential shear is range dependent (e.g., Stumpf et al. 1998), with lower thresholds at farther ranges because the measured peak velocity values - relative to the true values - decrease with range as a result of beam broadening (e.g., Donaldson 1970).
