The data revealed bands up to six kilometers deep, spaced from 20 40 km apart. The Doppler spectra were retrieved from the profiler data during PlOWS, as well as the signal-to-noise ratio (SNR, similar to radar reflectivity) and total vertical velocity. After correcting the total vertical velocity for spectral broadening due to wind shear and the contribution of the horizontal wind speed due to the wide beamwidth, vertical air motion was retrieved above the bright band in several bands from the three cases. Analysis of these Doppler spectra indicated a high correlation between the vertical velocity and the signal-to-noise ratio (SNR) of the bands. High velocities corresponded to higher SNR values and low (even negative) velocities to lower SNR values. The retrieved velocities are believed to be the first measurements of vertical velocities within these bands and were surprisingly large, between 1-2 m s-1. The complete methodology and results will be presented.
