摘要: |
During the first year of this contract, research was directed toward the development of new techniques to monitor and forecast weather related aviation hazards with Doppler weather radar. Focus was on the characterization of the structure of severe convective storms and of synoptic scale baroclinic fronts. One aspect that was examined is the detection and quantization of the weak echo region usually seen in severe convective storms. Another has been the search for lightning precursors. Finally, considerable effort has been expended on the automated depiction of the wind and precipitation structure associated with baroclinic fronts.
