| Zusammenfassung |
| A field campaign was carried out from 26
October to 7 November 1992, using the SOUSY-VHF radar and a mobile rawinsonde
system installed and operated nearby to produce vertical wind profiles. The
purpose of this campaign was to compare the two types of wind measurements with
one another and with results from forecast models. Numerical algorithms were
developed and applied to the radar data in order to eliminate random errors,
correct for velocity aliasing, and calculate the effective zenith angle of the
off-vertical beams. Differences between wind profiler data and rawinsonde or
model results depend not only upon the errors of the different systems, but also
on temporal and spatial variations of the wind field. Therefore, methods for the
comparison of radar and rawinsonde data were developed which take into
consideration these variations. The practical potential of these methods is
demonstrated by comparisons of rawinsonde and radar wind profiles. The
comparison of radar data and model output shows excellent agreement in the
direction and in the speed of the wind at virtually all altitudes. An evaluation
of the quality of wind profiler measurements is possible using the estimation of
variance and variability of wind components. |
