Abstract
Sensitive research Doppler radars and now the operational WSR-88D and TDWR radars routinely observe clear-air echo in the boundary layer to ranges of at least 50-100 km during the warm season. Clear-air echo is also observed during the cold seasons, however, not as frequently nor to as great a range. It has become routine for both research and operational meteorologists to assume that clear-air echo accurately portrays the actual winds. However, in the case of particulate scattering the accuracy of this assumption is not clear. The purpose of this paper is two-fold: first to examine the origin and characteristics of clear-air radar echoes with multi-parameter radar data and second to examine the accuracy of clear-air wind fields derived from Doppler radar data. The radars used for this study are the NCAR multi-weavelenght (S- and X-band) dual-polarization Doppler radar, CP-2, and two C-band Doppler radars, CP-3 and CP-4. Data are presented from Florida and Colorado.
