The testing and evaluation of new observing systems (VHF-45MHz, UHF-961 MHz wind profilers) as well as their performance in a network was listed among the goals of the FRONTS87 European field experiment. Using the FRONTS87 dataset for the 12-13 January 1988 cold front, the two horizontal wind components from the INSU-METEO VHF and UHF wind profilers are' quantitatively compared with those derived from collocated special upper-air soundings. Comparison between the sounding and the protilers data shows good agreement with rms differences of 4-4·5 ms-1 for the VHF and 2·2ms-1 for the UHF wind profiler. The combined use of the two profilers with their high timeresolution data (one vertical profile every 15min) along with the high altituderesolution data of the UHF profiler (150m) allowed us to obtain, in precipitation as well as in clear sky areas, a detailed image of both the low-level and upperlevel jet associated with the cold front observed over Brittany France, 12-13 January 1988. The case-study analysis illustrates the potential application of the French UHF and VHF wind profiling systems for describing synoptic and mesoscale wind regimes. |
