Zusammenfassung |
As an introduction to this special issue of
Annales Geophysicae a review is given of the applicability and performance of
wind profilers. In meteorology, wind profilers play an increasingly important
role. They can provide upper-wind measurements with an accuracy comparable to
radiosonde data, but with a significantly higher temporal resolution. Height
coverage and vertical resolution depend on the operating frequency, which,
depending on the application, is usually chosen to be around 50, 400 or 1000
MHz. Measurements from stand-alone profilers in sparse data areas as well as
data from wind profiler networks - which have increased the spatial resolution
of an existing radiosonde network - have shown a positive impact on numerical
weather forecasting. Information from nearby profilers can help the individual
meterologist to optimize local short-term weather forecasts. In atmospheric
research, wind profilers have been used for various boundary layer studies. In
several mesoscale monitoring experiments wind profilers have played an important
role. In Europe the development and implementation of wind profiler networks
have been supported since 1987 by the CEC-sponsored COST-74 project. A follow-up
project will probably start in 1994. Several topics deserve attention. A further
assessment of the quality of wind profiler measurements is important. Automatic
quality control procedures should be refined. Improved data assimilation
techniques in numerical models will enable a better use of the high temporal
resolution of wind profiler data. For a cost-effective development and use of
wind profilers, the realization of frequency allocations, as globally harmonized
as possible, is essential. Finally, the integration of wind profilers with other
complementary measuring techniques is important. |
