Using WSR-88D Polarimetric Data to Identify Bird-Contaminated Doppler Velocities
Figure 8
Vertical profiles of (a) absolute value (m s−1) and (b) azimuthal angle (clockwise from the north) for two types of horizontal velocities: (i) the horizontal velocity of air plus birds (plotted by the solid profiles) produced by the VAD analysis from the KICT-scanned volumetric velocity data at 090142 UTC but within the 150 km radial range to cover BSb pixels only and (ii) the horizontal velocity of air (plotted by the dashed profiles) interpolated from RAP hourly wind analyses to the KICT radar location at 090142 UTC on 30 September 2012. The absolute value and azimuthal angle of the vector difference of the above two velocities (the first minus the second velocity) are plotted by the dotted vertical profiles in panels (a) and (b), respectively.
